The GoogleStorage class implements the Google Storage for Developers API.

Syntax

cloudstorage.googlestorage()

Remarks

GoogleStorage allows you to easily manage storing and retrieving files using the Google Storage for Developers service.

Before using the class you must have a valid Google Storage account.

Authentication

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth* properties to set the appropriate fields for the chosen OAuthClientProfile and OAuthGrantType.

The class has the following defaults:

Below is a brief description of the different OAuthClientProfile and OAuthGrantType values that are supported by this class. For a more in-depth description of what needs to be set, refer to the service documentation.

Application Profile

This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the class. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.

To start the authentication and authorization process, the Authorize method should be called. If the authorization and authentication was successful, then the OAuthAccessToken property will be populated. Additionally, if a refresh token was provided the OAuthRefreshToken property will be populated as well. These values of the fields are for informational purposes. The class will also cache these tokens along with when the OAuthAccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the class will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new OAuthAccessToken. If the Authorize method was not used and user interaction would be required, the class will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the OAuthGrantType property. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.

A brief description of the supported values for the OAuthGrantType property are below. For more information, see the service documentation.

Authorization Code

When using the Authorization Code grant type, the class will use an authorization code to get an access token. For this OAuthGrantType the class expects a OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, and OAuthServerTokenURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the authorization code, setting the OAuthAuthorizationCode property, from the redirect. Immediately, the class will make a request to the token server to exchange the authorization code for an access token. The token server will return an access token and possibly a refresh token. If the OAuthRefreshToken property is set, or a refresh token is cached, then the class will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.

Example: GoogleStorage googlestorage = new GoogleStorage(); googlestorage.OAuth.ClientProfile = OAuthClientProfiles.cocpApplication; googlestorage.OAuth.GrantType = OAuthGrantTypes.cogtAuthorizationCode; googlestorage.OAuth.ClientId = CLIENT_ID; googlestorage.OAuth.ClientSecret = CLIENT_SECRET; googlestorage.Authorize();

Implicit

Note: This grant type is considered insecure and should only be used when necessary.

When using the Implicit grant type, the class will request the authorization server to get an access token. For this OAuthGrantType the class expects a OAuthClientId, OAuthClientSecret, and OAuthServerAuthURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the access token from the redirect.

A disadvantage of the grant type is that can not use a refresh token to silently get a new access token. Most service providers offer a way to silently get a new access token. See the service documentation for specifics. This means the class will not be able to automatically get a fresh token once it expires.

Web Profile

External OAuth Support

Bearer ACCESS_TOKEN_VALUE

Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the class to ignore the values set in the OAuth property.

For Example: Oauth oauth = new Oauth(); oauth.ClientId = "CLIENT_ID"; oauth.ClientSecret = "CLIENT_SECRET"; oauth.AuthorizationScope = "https://www.googleapis.com/auth/cloud-platform"; oauth.ServerAuthURL = "https://accounts.google.com/o/oauth2/auth"; oauth.ServerTokenURL = "https://accounts.google.com/o/oauth2/token"; oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode; googlestorage.Authorization = oauth.GetAuthorization(); Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Once you have a valid Google Storage account you can start creating buckets in your account using CreateBucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using CreateObject.

There are other methods such as ListBuckets, ListObjects, GetObject, DeleteObject etc. that further enable you to manage your Google Storage data store.

When authenticating via OAuth the ProjectId property is also required.

Alternatively, this service also supports authenticating by setting the AccessKey and SecretKey configuration settings.

• CreateBucket
• CreateObject
• StartMultipartUpload
• UpdateBucketACL
• UpdateObjectACL

Valid values are:

GoogleStorage.Authorization Property

OAuth 2.0 Authorization Token.

Syntax

getAuthorization(): string;
setAuthorization(authorization: string): void;

Default Value

""

Remarks

This class supports authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth* properties, using the OAuth class or a separate process. If using the OAuth* properties, then the Authorization property will not be used.

Bearer ACCESS_TOKEN

GoogleStorage.Bucket Property

Selects a bucket.

Syntax

getBucket(): string;
setBucket(bucket: string): void;

Default Value

""

Remarks

This property selects a bucket, by name, for the class to operate against. It must be set before attempting most operations.

GoogleStorage.Buckets Property

A collection of buckets.

Remarks

This collection holds a list of S3Bucket items.

Calling ListBuckets will populate this collection.

This property is read-only and not available at design time.

GoogleStorage.ContentDisposition Property

Content disposition to send for an object.

Syntax

getContentDisposition(): string;
setContentDisposition(contentDisposition: string): void;

Default Value

""

Remarks

This property can be set before calling CreateObject to have its value submitted as the object's Content-Disposition header value. This same value will then be returned in the Content-Disposition header by the server anytime the object is downloaded.

This property is not available at design time.

GoogleStorage.ContentType Property

Content type to send for an object.

Syntax

getContentType(): string;
setContentType(contentType: string): void;

Default Value

""

Remarks

This property can be set before calling CreateObject to have its value submitted as the object's Content-Type header value. This same value will then be returned in the Content-Type header by the server anytime the object is downloaded.

This property is not available at design time.

GoogleStorage.EncryptionAlgorithm Property

The encryption algorithm.

Syntax

getEncryptionAlgorithm(): GooglestorageEncryptionAlgorithms;
setEncryptionAlgorithm(encryptionAlgorithm: GooglestorageEncryptionAlgorithms): void;

enum GooglestorageEncryptionAlgorithms {

GoogleStorage.EncryptionPassword Property

The encryption password.

Syntax

getEncryptionPassword(): string;
setEncryptionPassword(encryptionPassword: string): void;

Default Value

""

Remarks

If this property is populated when UploadFile or DownloadFile is called, the class will attempt to encrypt or decrypt the data before uploading or after downloading it.

The class uses the value specified here to generate the necessary encryption Key and IV values using the PKCS5 password digest algorithm. This provides a simpler alternative to creating and managing Key and IV values directly.

However, it is also possible to explicitly specify the Key and IV values to use by setting the EncryptionKey and EncryptionIV configuration settings. This may be necessary if, e.g., the data needs to be encrypted/decrypted by another utility which generates Key and IV values differently.

This property is not available at design time.

""

Remarks

This property specifies the location of a file on disk. This is used as the source file when calling CreateObject or UploadPart; and as the destination file when calling GetObject.

GoogleStorage.LocalHost Property

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

getLocalHost(): string;
setLocalHost(localHost: string): void;

Default Value

""

Remarks

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

GoogleStorage.Metadata Property

A collection of metadata items.

Syntax

getMetadata(): S3MetadataList;
setMetadata(metadata: S3MetadataList): void;

Default Value

Remarks

This collection holds a list of S3Metadata items.

Syntax

getObjectData(): Uint8Array;
setObjectData(objectData: Uint8Array): void;

Default Value

""

Remarks

This property is populated with object data after calling GetObject if LocalFile is not set.

This property can also be set before calling CreateObject or UploadPart; its data will be uploaded if LocalFile is not set.

This property is not available at design time.

GoogleStorage.ObjectDelimiter Property

The delimiter string to use when listing objects.

Syntax

getObjectDelimiter(): string;
setObjectDelimiter(objectDelimiter: string): void;

Default Value

""

Remarks

If this property is non-empty when ListObjects or ListVersions is called, any objects (or object versions) whose names contain the same string between the specified ObjectPrefix and the first occurrence of the specified delimiter that follow will be rolled up into a "common prefix" element, which is returned in place of the individual objects themselves.

The PrefixList event will fire once for each common prefix returned. If the StorePrefixList configuration setting is enabled, the class will also populate the PrefixCount and Prefix[i] configuration settings

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

This property is not available at design time.

GoogleStorage.ObjectMarker Property

A marker indicating what page of objects to return next.

Syntax

getObjectMarker(): string;
setObjectMarker(objectMarker: string): void;

Default Value

""

Remarks

This property will be populated when ListObjects is called if the results are paged and there are more pages. To list all objects, continue to call ListObjects until this property returns empty string.

Refer to ListObjects for more information.

This property is not available at design time.

GoogleStorage.ObjectPrefix Property

A prefix used to restrict the results returned when listing objects.

Syntax

getObjectPrefix(): string;
setObjectPrefix(objectPrefix: string): void;

Default Value

""

Remarks

This property, if non-empty, is used to restrict the results returned by ListObjects (or ListVersions) to only the objects (or object versions) whose names begin with the given value.

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

This property is not available at design time.

GoogleStorage.Objects Property

A collection of objects.

Syntax

getObjects(): S3ObjectList;
setObjects(objects: S3ObjectList): void;

Default Value

Remarks

This collection holds a list of S3Object items.

Calling GetObjectInfo, ListObjects, or ListVersions will populate this collection.

This property is not available at design time.

GoogleStorage.OtherHeaders Property

This property includes other headers as determined by the user (optional).

Syntax

getOtherHeaders(): string;
setOtherHeaders(otherHeaders: string): void;

Default Value

""

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties like ContentType and From.

The headers must follow the format Header: Value as described in the HTTP specifications. Header lines should be separated by .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the class beyond what is provided.

This property is not available at design time.

GoogleStorage.Overwrite Property

Determines if local files are overwritten.

Syntax

isOverwrite(): boolean;
setOverwrite(overwrite: boolean): void;

Default Value

FALSE

Remarks

This property controls whether local files are overwritten when calling GetObject. It is only applicable to local files. The default value is false.

GoogleStorage.ParsedHeaders Property

This property includes a collection of headers returned from the last request.

Syntax

getParsedHeaders(): HeaderList;

Default Value

Remarks

This property contains a collection of headers returned from the last request. Whenever headers are returned from the server, the headers are parsed into a collection of headers. Each Header in this collection contains information describing that header.

MaxHeaders can be used to control the maximum number of headers saved.

This property is read-only and not available at design time.

GoogleStorage.ProjectId Property

The Id of the project.

Syntax

getProjectId(): string;
setProjectId(projectId: string): void;

Default Value

""

Remarks

This property specifies the user's project Id obtained from the Google API Console. It is required when authentication using OAuth 2.0.

GoogleStorage.Proxy Property

A set of properties related to proxy access.

Additional query parameters to be included in the request.

Syntax

getQueryParams(): QueryParamList;
setQueryParams(queryParams: QueryParamList): void;

Default Value

Remarks

This is a collection of query parameters that will be added to the request. Parameters can be added via the AddQueryParam method.

GoogleStorage.Range Property

The range of bytes to request.

Syntax

getRange(): string;
setRange(range: string): void;

Default Value

""

Remarks

This property specifies the range of bytes to request from the server. If this property is non-empty when a GetObject request is being constructed, a header like Range: bytes=Range will be added to the request, with Range substituted with the specified value.

There are two valid formats for this property's value:

• StartByte-
• StartByte-EndByte

Note: If the StartByte property is greater than zero when GetObject is called (i.e., when a download is being resumed), and this property is non-empty, the class will automatically advance the StartByte value in the specified range by StartByte bytes when sending the Range header to the server. This ensures that the previously-downloaded data at the start of the specified range is not downloaded again when the download is resumed.

This property is not available at design time.

GoogleStorage.Region Property

The location the class will create buckets in.

Syntax

getRegion(): string;
setRegion(region: string): void;

Default Value

"us"

Remarks

This property control which location the class will create buckets in. By default the class uses us, the US-regional location. This property should be changed to create buckets in other locations.

Regions:

The class will always convert this property's value to lowercase. If this property is cleared, the class will reset it to the default value.

GoogleStorage.SSLAcceptServerCert Property

Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.

Syntax

getSSLAcceptServerCert(): Certificate;
setSSLAcceptServerCert(SSLAcceptServerCert: Certificate): void;

Default Value

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

GoogleStorage.SSLCert Property

The certificate to be used during SSL negotiation.

Syntax

getSSLCert(): Certificate;
setSSLCert(SSLCert: Certificate): void;

Default Value

Remarks

The digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the field to the encoded certificate. To select a certificate, use the store and subject fields.

GoogleStorage.SSLProvider Property

This specifies the SSL/TLS implementation to use.

Syntax

getSSLProvider(): GooglestorageSSLProviders;
setSSLProvider(SSLProvider: GooglestorageSSLProviders): void;

enum GooglestorageSSLProviders {
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
}

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected the platform implementation will be used by default in all cases in the JavaScript edition.

Note: The Internal provider is not support at this time.

GoogleStorage.SSLServerCert Property

The server certificate for the last established connection.

Syntax

getSSLServerCert(): Certificate;

Default Value

Remarks

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

GoogleStorage.StartByte Property

The byte offset from which to resume the download.

Syntax

getStartByte(): number;
setStartByte(startByte: number): void;

Default Value

0

Remarks

This property specifies the byte offset from which to resume a download initiated by GetObject; refer to its documentation for more information.

This property is not available at design time.

GoogleStorage.Timeout Property

A timeout for the class.

Syntax

getTimeout(): number;
setTimeout(timeout: number): void;

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class .

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

GoogleStorage.UseSSL Property

Whether to use SSL/TLS when connecting.

Syntax

isUseSSL(): boolean;
setUseSSL(useSSL: boolean): void;

Default Value

TRUE

Remarks

This property specifies whether the class should use SSL/TLS when connecting.

This property is not available at design time.

GoogleStorage.UseVirtualHosting Property

Determines which style request to use.

Syntax

isUseVirtualHosting(): boolean;
setUseVirtualHosting(useVirtualHosting: boolean): void;

Default Value

TRUE

Remarks

If set to true (default), buckets will be referenced in the request using the hosted-style request: http://yourbucket.storage.googleapis.com/yourobject. If false, the class will use the path-style request: http://storage.googleapis.com/yourbucket/yourobject.

NOTE: When set to true, there are more limitations when choosing a bucket name due to DNS server naming restrictions. See Google's documentation for more detailed naming information.

This property is not available at design time.

GoogleStorage.VersionId Property

The object version to make requests against.

Syntax

getVersionId(): string;
setVersionId(versionId: string): void;

Default Value

""

Remarks

This property can be set to the Id of a specific object version before calling the following methods in order to make requests against the specified object version instead of the base object; refer to each one's documentation for more information:

• CopyObject (to copy from a specific object version)
• DeleteObject
• GetLink (to build a link for a specific object version)
• GetObject
• GetObjectInfo
• SendCustomRequest
• UpdateObjectACL

Refer to Amazon's Versioning documentation for more information about versioning.

This property is not available at design time.

GoogleStorage.VersionMarker Property

A marker indicating what page of object versions to return next.

Syntax

getVersionMarker(): string;
setVersionMarker(versionMarker: string): void;

Default Value

""

Remarks

This property will be populated when ListVersions is called if the results are paged and there are more pages. To list all object versions, continue to call ListVersions until this property returns empty string.

Refer to ListVersions for more information.

This property is not available at design time.

GoogleStorage.addMetadata Method

Adds a metadata item to the Metadata properties.

Syntax

async googlestorage.addMetadata(name : string, value : string): Promise<void>

Remarks

This method adds a metadata item to the Metadata* properties. Name specifies the name of the item, and Value specifies the value of the item. Keep in mind that the server stores metadata names in lowercase.

If Name begins with a service-specific metadata (e.g., x-amz-meta-, x-goog-meta-, etc.), it will be stripped off. The class will take care of prepending it when sending metadata to the server.

GoogleStorage.addQueryParam Method

Adds a query parameter to the QueryParams properties.

Syntax

async googlestorage.addQueryParam(name : string, value : string): Promise<void>

Remarks

This method is used to add a query parameter to the QueryaParam* properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the class automatically. Consult the service documentation for details on the available parameters.

GoogleStorage.authorize Method

Get the authorization string required to access the protected resource.

Syntax

async googlestorage.authorize(): Promise<void>

Remarks

This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the OAuthClientProfile property and the OAuthGrantType property. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth* properties.

For more information, see the introduction section.

GoogleStorage.bucketExists Method

Checks whether the bucket exists.

Syntax

async googlestorage.bucketExists(): Promise<boolean>

Remarks

This method checks whether the bucket specified by Bucket exists, returning true if so or false if not.

GoogleStorage.calcAuthorization Method

Calculates the Authorization header based on provided credentials.

Syntax

async googlestorage.calcAuthorization(): Promise<void>

Remarks

This method calculates the Authorization value using the values provided in AuthScheme, User and Password.

In most cases this method does not need to be called. The class will automatically calculate any required authorization values when a method is called such as Get or Post.

This method may be useful in cases where the Authorization value needs to be calculated prior to sending a request.

GoogleStorage.checkVersioningEnabled Method

Checks whether versioning is enabled for the currently selected bucket.

Syntax

async googlestorage.checkVersioningEnabled(): Promise<boolean>

Remarks

This method can be used to check whether the bucket currently selected by Bucket has versioning enabled.

Note that if Bucket is empty, or refers to a bucket that does not exist, this method will always return false when queried.

Refer to Amazon's Versioning documentation for more information about versioning.

GoogleStorage.composeObjects Method

Creates a composed object using multiple objects already on the server.

Syntax

async googlestorage.composeObjects(composedObjectName : string): Promise<void>

Remarks

This method is used to compose objects on the server. Object composition is a server-side method of building an object by concatenating multiple existing objects together. This feature is a simpler alternative to the typical multipart-upload method of building objects.

A composed object looks and acts just like a regular object. However, its data is determined by its component objects (that is, the objects that make it up) and the order in which they are composed together.

To use this method, specify the names of the objects that should be composed together using the Objects property. When this method is called, the ComposedObjectName parameter determines what name is given to the resulting composed object. See the following code snippet for examples: // Upload some objects to start with. Let's assume we have some text files to upload. for (int i = 1; i <= 3; i++) { gstorage.LocalFile = "file" + i + ".txt"; gstorage.CreateObject("file" + i + ".txt"); } // Compose a new object. SetObjectNames("file1.txt", "file2.txt", "file3.txt"); gstorage.ComposeObjects("composed1.txt"); // Compose a new object using a composed object. SetObjectNames("file1.txt", "composed1.txt"); gstorage.ComposeObjects("composed2.txt"); // Compose onto an existing composed object. // (Similar to appending, but all server-side, no uploading needed.) SetObjectNames("file1.txt", "file2.txt"); gstorage.ComposeObjects("composed3.txt"); SetObjectNames("composed3.txt", "file3.txt"); gstorage.ComposeObjects("composed3.txt"); // Compose a new object using the same object twice. SetObjectNames("file1.txt", "file1.txt"); gstorage.ComposeObjects("composed4.txt"); // Compose a composed object onto itself. SetObjectNames("composed4.txt", "composed4.txt"); gstorage.ComposeObjects("composed4.txt"); Assume we have this helper method for the above code: void SetObjectNames(params string[] names) { gstorage.Objects.Clear(); foreach (string name in names) gstorage.Objects.Add(new S3Object(name, "", 0, "", "", "", "", "")); }

Object composition is a powerful and flexible feature. However, there are some things to keep in mind when doing object composition:

• The order of the object names in the Objects property is the order that they will be concatenated in when they are composed.
• Objects from multiple buckets cannot be composed together.
• No more than 32 object names may be specified in a single compose request.

GoogleStorage.config Method

Sets or retrieves a configuration setting.

Syntax

async googlestorage.config(configurationString : string): Promise<string>

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

GoogleStorage.copyObject Method

Copies an object.

Syntax

async googlestorage.copyObject(srcObjectName : string, destBucket : string, destObjectName : string): Promise<void>

Remarks

This method copies the object specified by SrcObjectName (in the bucket currently selected by Bucket) to the object specified by DestObjectName in DestBucket. If DestBucket is empty, the bucket specified by Bucket is used as the destination bucket.

If the VersionId property is non-empty, the specified version of the source object will be used as the copy source. In this case, DestObjectName may be the same as SrcObjectName to "promote" the version, copying its contents back to the base object.

If there are any metadata items present in the Metadata* properties, they will set on the destination object; otherwise, the server will copy any metadata items present on the source object to the destination object.

Notes:

• Objects may only be copied to buckets that exist within the same region.
• Objects larger than 5GB cannot be copied using this method. To copy such objects, start a new multipart upload for the destination object using StartMultipartUpload, and then use the CopyPart method to create parts for said multipart upload using the source object's data.

GoogleStorage.createBucket Method

Creates a new bucket.

Syntax

async googlestorage.createBucket(): Promise<void>

Remarks

This method creates a new bucket using the name specified by the Bucket property. The bucket is created in the region specified by the Region property.

GoogleStorage.createObject Method

Creates a new object in the currently selected bucket.

Syntax

async googlestorage.createObject(objectName : string): Promise<void>

Remarks

This method creates a new object named Object in the bucket currently selected by Bucket. If there are any metadata items present in the Metadata* properties, they will included in the creation request.

If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ObjectData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

This method can automatically handle the multipart upload of objects (See Below). If it is desired to manually take control of the multipart upload process see StartMultipartUpload.

GoogleStorage.deleteBucket Method

Deletes a bucket.

Syntax

async googlestorage.deleteBucket(): Promise<void>

Remarks

This method deletes the bucket currently selected by Bucket. Note that bucket names share a global namespace, and it may not be possible to recreate a deleted bucket if its name has been taken by another user in the meantime.

GoogleStorage.deleteObject Method

Deletes an object.

Syntax

async googlestorage.deleteObject(objectName : string): Promise<void>

Remarks

This method deletes the object specified by ObjectName in the bucket currently selected by Bucket.

If the VersionId property is non-empty, this method deletes the specified version of the object instead. Note that deleting the latest version of an object will not automatically "restore" the previous version.

GoogleStorage.disableVersioning Method

Disables versioning for the currently selected bucket.

Syntax

async googlestorage.disableVersioning(): Promise<void>

Remarks

This method can be used to disable versioning for the bucket currently selected by Bucket.

Refer to Amazon's Versioning documentation for more information about versioning.

GoogleStorage.doEvents Method

Processes events from the internal message queue.

Syntax

async googlestorage.doEvents(): Promise<void>

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

GoogleStorage.enableVersioning Method

Enables versioning for the currently selected bucket.

Syntax

async googlestorage.enableVersioning(): Promise<void>

Remarks

This method can be used to enable versioning for the bucket currently selected by Bucket.

Refer to Amazon's Versioning documentation for more information about versioning.

GoogleStorage.getBucketLocation Method

Gets a bucket's location.

Syntax

async googlestorage.getBucketLocation(): Promise<string>

Remarks

This method retrieves and returns the location (i.e., region) of the bucket currently selected by Bucket.

GoogleStorage.getObject Method

Downloads an object.

Syntax

async googlestorage.getObject(objectName : string): Promise<void>

Remarks

This methods downloads the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is non-empty, the specified version of the object is downloaded instead. The Range property can be used to download a specific range of bytes from the object.

If LocalFile is set, the object data will be saved to the specified location; otherwise, the object data will be held by ObjectData.

To download and decrypt an encrypted object, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading an object looks like this: s3.LocalFile = "../MyData.zip"; s3.GetObject(s3.Objects[0].Name);

Resuming Downloads

The class also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyData.zip"; s3.LocalFile = downloadFile; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded file s3.StartByte = new FileInfo(downloadFile).Length; s3.GetObject(s3.Objects[0].Name);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. s3.LocalFile = "../MyData.zip"; s3.EncryptionPassword = "password"; s3.GetObject(s3.Objects[0].Name); //The transfer is interrupted and GetObject() above fails. Later, resume the download: //Get the size of the partially downloaded temp file s3.StartByte = new FileInfo(s3.Config("DownloadTempFile")).Length; s3.GetObject(s3.Objects[0].Name);

GoogleStorage.getObjectInfo Method

Gets an object's information and metadata.

Syntax

async googlestorage.getObjectInfo(objectName : string): Promise<void>

Remarks

This method gets information and metadata for the object specified by Object in the bucket currently selected by Bucket. If the VersionId property is non-empty, information and metadata for the specified version of the object is retrieved instead.

Calling this method will fire the ObjectList and MetadataList events, and will re-populate the Objects* and Metadata* properties.

GoogleStorage.interrupt Method

Interrupt the current method.

Syntax

async googlestorage.interrupt(): Promise<void>

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

GoogleStorage.listBuckets Method

Lists all buckets in the account.

Syntax

async googlestorage.listBuckets(): Promise<void>

Remarks

This method lists all buckets in the account.

Calling this method will fire the BucketList event once for each bucket, and will also populate the Buckets* properties.

GoogleStorage.listObjects Method

Lists the objects in a bucket.

Syntax

async googlestorage.listObjects(): Promise<void>

Remarks

This method lists the objects in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the objects whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the ObjectList event once for each object, and will also populate the Objects* properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more objects available to list when this method returns, the ObjectMarker property will be populated. Continue to call this method until ObjectMarker is empty to accumulate all pages of results in the Objects* properties.

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

GoogleStorage.listVersions Method

Lists the object versions in a bucket.

Syntax

async googlestorage.listVersions(): Promise<void>

Remarks

This method lists the object versions in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the object versions whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.

Calling this method will fire the ObjectList event once for each object version, and will also populate the Objects* properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If there are still more object versions available to list when this method returns, the VersionMarker property will be populated. Continue to call this method until VersionMarker is empty to accumulate all pages of results in the Objects* properties.

Object Hierarchy Traversal

By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

• MyCompany/
• MyCompany/Department1/
• MyCompany/Department2/
• MyCompany/Department2/EmployeeA
• MyCompany/Department2/EmployeeB

With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:

GoogleStorage.reset Method

Resets the class to its initial state.

Syntax

async googlestorage.reset(): Promise<void>

Remarks

This method resets the class to its initial state.

GoogleStorage.resetHeaders Method

Resets all HTTP headers, cookies, and LocalFile.

Syntax

async googlestorage.resetHeaders(): Promise<void>

Remarks

Resets all the HTTP headers as well as LocalFile to "" (empty string), and clears the Metadata* and QueryParam* properties.

Call this method before creating a new request, so that headers and query parameters from the previous request are not carried over to the next one.

GoogleStorage.sendCustomRequest Method

Sends a custom request to the server.

Syntax

async googlestorage.sendCustomRequest(httpMethod : string, objectName : string, requestBody : string): Promise<void>

Remarks

This method can be used to send arbitrary requests to the server.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• DELETE

The ObjectName and RequestBody parameters may be empty if not needed.

Usage

When this method is called, the class does the following:

1. Builds a request URL, including query parameters, based on the following:
   • UseSSL, Region, and UseVirtualHosting for the base URL.
     • Alternatively, if a custom URL has been specified using the URL configuration setting, it is used directly, and these properties are ignored.
   • Bucket (if non-empty)
   • ObjectName (if non-empty)
   • VersionId (if both it and ObjectName are non-empty)
   • QueryParam*
2. Adds request headers from:
   • ContentDisposition
   • ContentType
   • OtherHeaders
   • ProductToken
   • SessionToken
   • UserToken
3. Signs the request (unless the SignCustomRequest configuration setting is disabled).
4. Sends the request, including RequestBody if non-empty.
5. Stores the response headers in the ParsedHeader* properties; and the response body in the specified LocalFile, or ObjectData (using the same logic as GetObject).

If the response body is XML data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

GoogleStorage.updateBucketACL Method

GoogleStorage.MetadataList Event

Fires once for each metadata item returned when object information and metadata is retrieved.

Syntax

googlestorage.on('MetadataList', listener: (e: {readonly name: string, readonly value: string}) => void )

Remarks

This event fires once for each metadata item returned when GetObjectInfo is called.

Name is the name of the metadata item, without the service-specific prefix (e.g., x-amz-meta-, x-goog-meta-, etc.). Keep in mind that the server stores metadata names in lowercase.

Value is the metadata item's value.

GoogleStorage.ObjectList Event

Fires once for each object, object version, or multipart upload returned when listing such items.

Syntax

googlestorage.on('ObjectList', listener: (e: {readonly bucketName: string, readonly objectName: string, readonly lastModified: string, readonly size: number, readonly ETag: string, readonly ownerId: string, readonly ownerName: string, readonly uploadId: string, readonly versionId: string, readonly latestVersion: boolean, readonly deleted: boolean}) => void )

GoogleStorage.Progress Event

Fires during an upload or download to indicate transfer progress.

Syntax

googlestorage.on('Progress', listener: (e: {readonly direction: number, readonly bytesTransferred: number, readonly totalBytes: number, readonly percentDone: number}) => void )

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the class tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the class will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

GoogleStorage.SSLServerAuthentication Event

Fired after the server presents its certificate to the client.

Syntax

googlestorage.on('SSLServerAuthentication', listener: (e: {readonly certEncoded: string, readonly certEncodedB: Uint8Array, readonly certSubject: string, readonly certIssuer: string, readonly status: string, accept: boolean}) => void )

Remarks

This event fires with information about the server certificate. The Status property shows why verification failed (otherwise, Status contains the string OK). To manually accept an untrusted certificate, the SSLAcceptAnyServerCert setting must be set to True before initiating the connection.

Fired when secure connection progress messages are available.

Syntax

googlestorage.on('SSLStatus', listener: (e: {readonly message: string}) => void )

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

GoogleStorage.StartTransfer Event

This event fires when a document starts transferring (after the headers).

Syntax

googlestorage.on('StartTransfer', listener: (e: {readonly direction: number}) => void )

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

GoogleStorage.Transfer Event

This event is fired while a document transfers (delivers document).

Syntax

googlestorage.on('Transfer', listener: (e: {readonly direction: number, readonly bytesTransferred: number, readonly percentDone: number, readonly text: string, readonly textB: Uint8Array}) => void )

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
