Remarks

The S3 class allows you to access Amazon's Simple Storage Service (S3), as well as other S3-compatible services, in a secure manner using Secure Sockets Layer/Transport Layer Security (TLS/SSL). S3-like services allow you to store arbitrary data objects in various buckets and to access them from anywhere with an internet connection.

A brief synopsis follows, but please refer to Amazon's S3 documentation for more information about the general capabilities of S3.

S3 supports the following providers:

• Amazon S3
• Backblaze B2
• Cloudflare R2
• Digital Ocean Spaces
• Google Cloud Storage
• IBM Cloud Object Storage
• Linode Object Storage
• Oort DSS
• Oracle Cloud Object Storage
• Seagate Lyve Cloud
• Wasabi
• And more!

A "custom provider" option also allows you to interact with any S3-compatible API by specifying its base URL.

Getting Started

To begin, use the ServiceProvider property to select the S3 service provider to use. Then, use the AccessKey and SecretKey properties to specify the access key and secret key that the class should use to sign requests. These keys can be obtained after signing up for an account with the selected service provider.

Working with Buckets

S3 services store objects in various buckets. The following methods can be used to interact with the buckets in an S3 account:

• Creating and deleting buckets: CreateBucket and DeleteBucket
• Checking whether a bucket exists, and its location: BucketExists and GetBucketLocation
• Listing buckets: ListBuckets
• Updating a bucket's canned ACL: UpdateBucketACL

Working with Objects

Once the desired buckets are ready, the following methods can be used to interact with objects:

• Creating, downloading, and deleting objects: CreateObject, GetObject, DeleteObject
• Copying objects: CopyObject
• Listing objects, or getting information about a single object: ListObjects, GetObjectInfo
• Updating an object's canned ACL: UpdateObjectACL

Working with Multipart Uploads

For S3 providers that support them, multipart uploads make it possible to upload very large objects in multiple parts.

• Starting, completing, and aborting multipart uploads: StartMultipartUpload, CompleteMultipartUpload, AbortMultipartUpload
• Listing multipart uploads: ListMultipartUploads
• Uploading and copying parts: UploadPart, CopyPart
• Listing parts: ListParts

Cloudflare R2 Notes

The Cloudflare R2 service provider possesses the following unique requirements and characteristics:

• In addition to needing an AccessKey and SecretKey, a CloudflareAccountID is also required to work with this provider.
• The Region property is automatically set to "auto" when this service provider is selected, which is the only valid value.
• ListParts is not supported natively by Cloudflare R2, which means that the behavior of CompleteMultipartUpload changes when using this provider. Instead, calling UploadPart or CopyPart populates the LastPartInfo and PartInfo[i] configuration settings. CompleteMultipartUpload will then use the values in PartInfo[i] to complete the multipart upload.

Other Features

The S3 class also supports a variety of other features, including the following:

• Versioning support
• Object metadata manipulation
• Presigned link generation

Default Value

''

Remarks

This 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 multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

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 multihomed 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.

Binary String

ObjectDelimiter Property (CloudStorage_S3 Class)

This property includes the delimiter string to use when listing objects.

Object Oriented Interface

public function getObjectDelimiter();
public function setObjectDelimiter($value);

Procedural Interface

cloudstorage_s3_get($res, 28 );
cloudstorage_s3_set($res, 28, $value );

Default Value

''

Remarks

If this property is nonempty 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.

The PrefixList event will fire once for each common prefix returned. If the StorePrefixList configuration setting is enabled, the class also will 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:

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:

Following are the 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 nonempty, 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 are not downloaded again when the download is resumed.

This property is not available at design time.

The custom service provider's "default region" is an empty string (i.e., setting ServiceProvider to spCustom (255) will clear this property).

Note: When the custom service provider is selected, the class uses the base URL specified by the ServiceProviderURL configuration setting to generate request URLs. If the base URL contains a %region% token, the class will replace it with this property's value any time it generates a request URL. Refer to the ServiceProviderURL setting's documentation for more information.

Amazon S3 Regions

Alibaba Cloud Object Storage Regions

Note: Optionally, private. or direct. may be prepended to any of the values above; refer to IBM Cloud's Object Storage documentation for information on regions and endpoints.

Linode Object Storage Regions

Important: Each "region" supported by Linode's Object Storage service is actually a completely standalone storage cluster. These clusters do not interact with each other in any way, which causes the following nonstandard behaviors:

• Bucket names may be reused in each region (however, they must still be "globally" unique within each region).
• The ListBuckets method will return only those buckets located in the currently selected region; there is no way to retrieve a list of all regions' buckets.
• Similarly, the BucketExists and GetBucketLocation methods consider only those buckets located in the currently selected region.
• The CopyObject method cannot be used to copy objects to a bucket in another region.

Note: When ServiceProvider is spLinode (9), this method considers only buckets located in the currently selected Region. Refer to the Linode section of the Region property's documentation for more information.

CheckVersioningEnabled Method (CloudStorage_S3 Class)

This method checks whether versioning is enabled for the currently selected bucket.

Object Oriented Interface

public function doCheckVersioningEnabled();

Procedural Interface

cloudstorage_s3_do_checkversioningenabled($res);

Remarks

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

Note: If Bucket is empty, or refers to a bucket that does not exist, this property will always return false when queried, and any attempts to set it will fail. This behavior also occurs if the currently selected service provider does not support versioning at all.

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

Note: When ServiceProvider is spBackblazeB2 (4), this property will always return true (assuming Bucket is nonempty), and any attempt to change it will fail; Backblaze B2 buckets are always versioned.

CompleteMultipartUpload Method (CloudStorage_S3 Class)

This method completes a multipart upload by assembling previously uploaded parts.

Object Oriented Interface

public function doCompleteMultipartUpload($objectname, $uploadid);

Procedural Interface

cloudstorage_s3_do_completemultipartupload($res, $objectname, $uploadid);

Remarks

This method completes the multipart upload specified by UploadId. The server will assemble all of the parts that have been uploaded into an object named ObjectName.

Note: This method automatically calls ListParts internally to obtain the information needed to complete the multipart upload. This process does not alter the Parts properties, nor does it cause the PartList event to fire. The spCloudflareR2 (10) ServiceProvider does not support the ListParts S3 operation; thus, when that provider is selected, this method instead relies on the part information contained in the PartInfo[i] configuration setting.

Config Method (CloudStorage_S3 Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

cloudstorage_s3_do_config($res, $configurationstring);

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.

CopyObject Method (CloudStorage_S3 Class)

This method copies an object.

Object Oriented Interface

public function doCopyObject($srcobjectname, $destbucket, $destobjectname);

Procedural Interface

cloudstorage_s3_do_copyobject($res, $srcobjectname, $destbucket, $destobjectname);

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

CopyPart Method (CloudStorage_S3 Class)

This method copies the specified object as a part of a multipart upload.

Object Oriented Interface

public function doCopyPart($srcobjectname, $destbucket, $destobjectname, $destpartnumber, $destuploadid);

Procedural Interface

cloudstorage_s3_do_copypart($res, $srcobjectname, $destbucket, $destobjectname, $destpartnumber, $destuploadid);

Remarks

This method copies data from the object specified by SrcObjectName (in the bucket currently selected by Bucket) to a new multipart upload part for DestObjectName in DestBucket.

The DestPartNumber and DestUploadId parameters should be used in the same manner as the UploadPart method's PartNumber and UploadId parameters.

To copy a specific range of bytes from the source object, set the CopyPartRange configuration setting before calling this method.

Note: This method is not supported when ServiceProvider is spGoogleStorage (2).

CreateBucket Method (CloudStorage_S3 Class)

This method creates a new bucket.

Object Oriented Interface

public function doCreateBucket();

Procedural Interface

cloudstorage_s3_do_createbucket($res);

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.

CreateObject Method (CloudStorage_S3 Class)

This method creates a new object in the currently selected bucket.

Object Oriented Interface

public function doCreateObject($objectname);

Procedural Interface

cloudstorage_s3_do_createobject($res, $objectname);

Remarks

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

Automatic Multipart Uploads

If more than SimpleUploadLimit bytes of data are provided, the class will automatically perform a multipart upload by splitting the data up into parts (sized according to the FragmentSize configuration setting) and uploading them individually. To accomplish this, the class automatically makes calls to StartMultipartUpload, UploadPart, and CompleteMultipartUpload internally; tracks the upload state information using the ResumableUploadState configuration setting; and tracks how much data have been uploaded using the StartByte property. The FragmentComplete event will fire after each part is uploaded.

If, during an automatic multipart upload, any individual request fails, the upload can be resumed be calling this method again with the same parameters, so long as ResumableUploadState and StartByte contain the same values as they did when the upload was interrupted.

When an automatic multipart upload completes successfully, ResumableUploadState is cleared and StartByte is reset to 0.

DeleteBucket Method (CloudStorage_S3 Class)

This method deletes a bucket.

Object Oriented Interface

public function doDeleteBucket();

Procedural Interface

cloudstorage_s3_do_deletebucket($res);

Remarks

This method deletes the bucket currently selected by Bucket.

Note: For some service providers, 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. Refer to the provider's documentation for more information.

DeleteObject Method (CloudStorage_S3 Class)

This method deletes an object.

Object Oriented Interface

public function doDeleteObject($objectname);

Procedural Interface

cloudstorage_s3_do_deleteobject($res, $objectname);

Remarks

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

If the VersionId property is nonempty, this method deletes the specified version of the object instead.

Deleting Versioned Objects

If a bucket has versioning enabled (i.e., CheckVersioningEnabled returns true when queried), and this method is called on an object rather than a specific object version, then instead of actually deleting any data, the server will simply create a special object version called a delete marker.

If an object's latest version is a delete marker, then the server treats the object as if it did not exist (i.e., it does not appear when listing objects or it cannot be downloaded). If, however, all of the previous versions of the object (including the one that existed just before the delete marker was created) still exist, then they can be listed using ListVersions and explicitly can be interacted with by setting VersionId and calling an appropriate method.

To permanently delete objects in a versioning-enabled bucket, each version of the object must be explicitly deleted by setting VersionId before calling this method. This includes any delete marker versions, which can be deleted like any other version.

Refer to Amazon's Deleting Object Versions, Working with Delete Markers, and Removing Delete Markers articles for more information.

DisableVersioning Method (CloudStorage_S3 Class)

This method disables versioning for the currently selected bucket.

Object Oriented Interface

public function doDisableVersioning();

Procedural Interface

cloudstorage_s3_do_disableversioning($res);

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.

DoEvents Method (CloudStorage_S3 Class)

This method processes events from the internal message queue.

Object Oriented Interface

public function doEvents();

Procedural Interface

cloudstorage_s3_do_doevents($res);

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.

EnableVersioning Method (CloudStorage_S3 Class)

This method enables versioning for the currently selected bucket.

Object Oriented Interface

public function doEnableVersioning();

Procedural Interface

cloudstorage_s3_do_enableversioning($res);

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.

GetBucketLocation Method (CloudStorage_S3 Class)

This method gets a bucket's location.

Object Oriented Interface

public function doGetBucketLocation();

Procedural Interface

cloudstorage_s3_do_getbucketlocation($res);

Remarks

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

Note: When ServiceProvider is spLinode (9), this method considers only buckets located in the currently selected Region. Refer to the Linode section of the Region property's documentation for more information.

GetLink Method (CloudStorage_S3 Class)

This method creates a link that provides access to an object for a specified amount of time.

Object Oriented Interface

public function doGetLink($objectname, $expires);

Procedural Interface

cloudstorage_s3_do_getlink($res, $objectname, $expires);

Remarks

This method creates and returns a preauthenticated link that provides access to the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is nonempty, a link is created for the specified version of the object.

The Expires parameter specifies how many seconds the link should be valid for. The maximum validity period is seven days.

Note: This method is an offline method that simply generates a presigned URL; no communication with the server takes place.

Note: This method is not supported when ServiceProvider is set to one of the following:

• spGoogleStorage (2)
• spOracle (8)

GetObject Method (CloudStorage_S3 Class)

This method downloads an object.

Object Oriented Interface

public function doGetObject($objectname);

Procedural Interface

cloudstorage_s3_do_getobject($res, $objectname);

Remarks

This methods downloads the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is nonempty, 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);

Example 1. 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);

Example 2. Resuming Encrypted File Downloads:

Resuming encrypted file downloads is supported only when LocalFile has been 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 are 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);

GetObjectInfo Method (CloudStorage_S3 Class)

This method gets an object's information and metadata.

Object Oriented Interface

public function doGetObjectInfo($objectname);

Procedural Interface

cloudstorage_s3_do_getobjectinfo($res, $objectname);

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 nonempty, information and metadata for the specified version of the object is retrieved instead.

Calling this method will fire the ObjectList and MetadataList events and also will repopulate the Objects and Metadata collection properties.

Interrupt Method (CloudStorage_S3 Class)

This method interrupts the current method.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

cloudstorage_s3_do_interrupt($res);

Remarks

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

ListBuckets Method (CloudStorage_S3 Class)

This method lists all buckets in the account.

Object Oriented Interface

public function doListBuckets();

Procedural Interface

cloudstorage_s3_do_listbuckets($res);

Remarks

This method lists all buckets in the account.

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

Note: When ServiceProvider is spLinode (9), this method returns only buckets located in the currently selected Region, and it is not possible to retrieve a list of all regions' buckets. Refer to the Linode section of the Region property's documentation for more information.

ListMultipartUploads Method (CloudStorage_S3 Class)

This method lists the current multipart uploads.

Object Oriented Interface

public function doListMultipartUploads();

Procedural Interface

cloudstorage_s3_do_listmultipartuploads($res);

Remarks

This method lists the current multipart uploads in the bucket currently selected by Bucket.

Before calling this method, the ObjectPrefix property may be set to restrict the results to only the multipart uploads whose names begin with a given string. The ObjectDelimiter property also can 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 multipart upload and also will populate the Objects properties.

If more multipart uploads are still 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 of the pages of results in the Objects properties.

Note: This method is not supported when ServiceProvider is spOortDSS (12).

Note: When the ServiceProvider is spSeagateLyveCloud (11) the ObjectPrefix property must be specified.

ListObjects Method (CloudStorage_S3 Class)

This method lists the objects in a bucket.

Object Oriented Interface

public function doListObjects();

Procedural Interface

cloudstorage_s3_do_listobjects($res);

Remarks

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

Before calling this method, the ObjectPrefix property may be set to restrict the results to only those objects whose names begin with a given string. The ObjectDelimiter property also can 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 also will populate the Objects properties. It also may fire the PrefixList event and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If more objects are still 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 of the 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:

ListParts Method (CloudStorage_S3 Class)

This method lists the parts in a multipart upload.

Object Oriented Interface

public function doListParts($objectname, $uploadid);

Procedural Interface

cloudstorage_s3_do_listparts($res, $objectname, $uploadid);

Remarks

This method lists the parts in the multipart upload of ObjectName specified by UploadId. The MaxParts configuration setting may be used to limit the number of results returned.

Calling this method will fire the PartList event once for each part and also will populate the Parts properties.

If more parts are still available to list when this method returns, the PartMarker property will be populated. Continue to call this method until PartMarker is empty to accumulate all of the pages of results in the Parts properties.

This method does not need to be called before attempting to complete a multipart upload with CompleteMultipartUpload; the class will automatically collect the necessary information internally. Refer to CompleteMultipartUpload for more information.

Note: spCloudflareR2 (10) does not support the ListParts S3 operation.

ListVersions Method (CloudStorage_S3 Class)

This method lists the object versions in a bucket.

Object Oriented Interface

public function doListVersions();

Procedural Interface

cloudstorage_s3_do_listversions($res);

Remarks

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

Before calling this method, the ObjectPrefix property may be set to restrict the results to only the object versions whose names begin with a given string. The ObjectDelimiter property also can 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 also will populate the Objects properties. It also may fire the PrefixList event and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.

If more object versions are still 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:

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

Valid values for HttpMethod are as follows:

• 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 ServiceProvider is spCustom (255), the custom URL specified using the ServiceProviderURL configuration setting is used directly, and these properties are ignored.
   • Bucket (if nonempty)
   • ObjectName (if nonempty)
   • VersionId (if both it and ObjectName are nonempty)
   • QueryParams
2. Adds request headers from the following:
   • ContentDisposition
   • ContentType
   • OtherHeaders
   • SessionToken
3. Signs the request (unless the SignCustomRequest configuration setting is disabled).
4. Sends the request, including RequestBody if nonempty.
5. Stores the response headers in the ParsedHeaders properties; and the response body in the specified LocalFile, or ObjectData (using the same logic as GetObject).

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

StartMultipartUpload Method (CloudStorage_S3 Class)

This method starts a new manual multipart upload.

Object Oriented Interface

public function doStartMultipartUpload($objectname);

Procedural Interface

cloudstorage_s3_do_startmultipartupload($res, $objectname);

Remarks

This method starts a new manual multipart upload for an object named ObjectName, in the bucket currently selected by Bucket, and returns the upload Id that the server associates with it. For an automatic multipart upload, see the CreateObject method. This upload Id can then be used to call the following methods:

• UploadPart
• CopyPart
• ListParts
• CompleteMultipartUpload
• AbortMultipartUpload

If any metadata items are present in the Metadata properties, they will be included in the creation request and will be applied to the final object after the multipart upload is completed with CompleteMultipartUpload.

Multipart uploads never expire, they must be explicitly completed or aborted using CompleteMultipartUpload or AbortMultipartUpload. The ListMultipartUploads method can be used to retrieve a list of current multipart uploads.

UpdateBucketACL Method (CloudStorage_S3 Class)

Progress Event (CloudStorage_S3 Class)

This event fires during an upload or download to indicate transfer progress.

Object Oriented Interface

public function fireProgress($param);

Procedural Interface

cloudstorage_s3_register_callback($res, 11, array($this, 'fireProgress'));

Parameter List

 'direction'
 'bytestransferred'
 'totalbytes'
 'percentdone'

Remarks

This event fires during an upload or download to indicate the progress of the transfer. By default, this event will fire each time PercentDone increases by 1 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 the note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown.

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 were transferred before the interruption.

For example, if 10 MB of data were successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10 MB) when the transfer is first resumed, and then will 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.

SSLServerAuthentication Event (CloudStorage_S3 Class)

Fired after the server presents its certificate to the client.

Object Oriented Interface

public function fireSSLServerAuthentication($param);

cloudstorage_s3_register_callback($res, 12, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
 'certsubject'
 'certissuer'
 'status'
 'accept'

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (CloudStorage_S3 Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

cloudstorage_s3_register_callback($res, 13, array($this, 'fireSSLStatus'));

 'text'

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.

Config Settings (S3 Class)
