OData Component

Properties   Methods   Events   Config Settings   Errors  

The OData component implements the Open Data Protocol (OData). It can be used to query, parse, and update or modify data contained within an OData service.

Syntax

IPWorks.Odata

Remarks

The OData Component supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.

The OData component allows you to easily query OData services and create, update, and delete entries within a service. To query a service, you can set the ServiceRootURI to the service's root URI and ResourcePath to the collection within the service that you wish to query. Optionally you can set the Query*** properties to filter the results. QueryService can then be called to retrieve the results (which can be viewed via the Entry*** properties).

Example 1. Query a Service: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products" OData1.QueryService()

To create a new entry, you can set the ServiceRootURI to the service's root URI and ResourcePath to the collection within the service that you wish to add the entry to. The Entry*** properties can be set to the values you wish to use to create the entry. CreateEntry can then be called to create the entry.

Example 2. Create a New Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products" OData1.EntryProperties OData1.CreateEntry()

If you wish to update an entry, you can set the ServiceRootURI to the service's root URI and ResourcePath to the specific entry you wish to update. The Entry*** properties can be set to the values you wish to update. UpdateEntry can then be called to update the entry.

Example 3. Update an Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products(1)" // Index 1 is the "Name" property. OData1.EntryProperties[1].Value = "MyNewName" OData1.UpdateEntry()

Deleting an entry requires that you first set the ServiceRootURI to the service's root URI and ResourcePath to the specific entry you wish to delete. DeleteEntry can then be called to delete the entry.

Example 4. Delete an Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products(1)" OData1.DeleteEntry()

In addition to querying a service and manipulating its containing data, the OData component also allows you to retrieve the schema (metadata document) to determine the structure of a service. After setting ServiceRootURI to the root URI of the service, GetSchema can be called to retrieve the metadata document. The Schema*** properties will be populated upon successful retrieval of the metadata document allowing you to identify the structure of the service.

Example 5. Retrieve the Scheme: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.GetSchema()

Authorization Property (OData Component)

This property includes the Authorization string to be sent to the server.

Syntax

public String getAuthorization();


public void setAuthorization(String authorization);

Default Value

""

Remarks

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP component can be extended with other security schemes in addition to the authorization schemes already implemented by the component.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

AuthScheme Property (OData Component)

The authentication scheme to use when server authentication is required.

Syntax

public int getAuthScheme();


public void setAuthScheme(int authScheme);

Enumerated values:
  public final static int authBasic = 0;

  public final static int authDigest = 1;

  public final static int authProprietary = 2;

  public final static int authNone = 3;

  public final static int authNtlm = 4;

  public final static int authNegotiate = 5;

  public final static int authOAuth = 6;

Default Value

0

Remarks

This property will tell the component which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the component will attempt HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.

If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the component.

For security, changing the value of this property will cause the component to clear the values of User, Password, and Authorization.

Syntax

public Certificate getSSLServerCert();

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.

Timeout Property (OData Component)

A timeout for the component.

Syntax

public int getTimeout();


public void setTimeout(int timeout);

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 component will wait for the operation to complete before returning control.

The component 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 component throws an exception.

Remarks

This property contains a user name if authentication is to be used. If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

If AuthScheme is set to HTTP Digest Authentication, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

If AuthScheme is set to NTLM, NTLM authentication will be attempted. If AuthScheme is set to NTLM, and User and Password are empty, the component will attempt to authenticate using the current user's credentials.

Config Method (Odata Component)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

CreateEntry Method (Odata Component)

This method creates a new entry within the specified OData service resource.

Syntax

public void createEntry();

Remarks

The component will use the items contained within EntryProperties to create a new entry within the feed service resource by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath).

Upon a successful creation, all previous entries contained by the component, before the CreateEntry call, will be cleared and replaced with the response entry data. EntryIndex will then be set to 0 (the first entry within the response), populating the EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, and EntryProperties properties. OtherHeaders will also be cleared and thus will need to be reset accordingly with each call made.

CustomRequest Method (Odata Component)

This method sends a request to the specified URL using the HTTPMethod and PostData provided.

Syntax

public void customRequest(String HTTPMethod, String URL, String postData);

Remarks

This method sends a custom request to the specified URL. The type of request sent is determined by HTTPMethod (e.g., POST) and the data sent are determined by PostData. If a custom request does not require data to be sent, simply set the PostData parameter to an empty string.

Note: All values specified are taken as entered.

OtherHeaders can be used to specify any additional headers you would like to be sent in the custom request.

The search results are delivered in the TransferredData property, as well as through the Transfer event. The response headers can be retrieved through the TransferredHeaders property as well as through the Header event.

The component will then attempt to parse the search results. Upon successfully parsing the response, Channel will be set with their associated feed element values and EntryCount will be populated with the total number of entries contained within the feed. EntryIndex also will be set to 1, thus populating EntryProperties.

DeleteEntry Method (Odata Component)

This method deletes an entry within an OData service resource.

Syntax

public void deleteEntry();

Remarks

The component will delete the entry, of an OData service resource, specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath).

An "If-Match" header will be sent in the delete request with the value contained within EntryETag.

Upon a successful entry deletion, all previous entries contained by the component, before the DeleteEntry call, will be cleared. OtherHeaders also will be cleared and thus will need to be reset accordingly with each call made.

GetEntryProperty Method (Odata Component)

This method gets an OData entry property.

Syntax

public String getEntryProperty(String XPath);

Remarks

This method is intended to extend the functionality of the OData component and will retrieve the value of the entry property specified by XPath. XPath is the XPath of the element or attribute according to the following convention: entry[x]/element@attribute. The @attribute part is optional. When EntryIndex is set to an index greater than or equal to zero, a relative path also can be used: property or property@attribute. When a relative path is specified, the value of the specified XPath will be returned for the entry identified by EntryIndex.

entry[x] is the feed's xth entry (or any other root-level child), where the indexer x starts at 1.

property is any child of the property's element, and attribute can be any attribute of that field. If an attribute is not supplied, the GetEntryProperty method will return the text portion of property.

Example 1. Attribute Not Supplied: ODataControl.GetEntryProperty("entry[5]/content/properties/ID") ODataControl.GetEntryProperty("entry[5]/content/properties/ID@type")

Example 2. Relative Path: In the following example, a relative path is used to retrieve properties of the first feed entry: ODataControl.EntryIndex = 1 ODataControl.GetEntryProperty("ID") ODataControl.GetEntryProperty("ID@type") ODataControl.GetEntryProperty("Address/State")

GetSchema Method (Odata Component)

This method retrieves the schema for a service.

Syntax

public void getSchema();

Remarks

Additional details about the schema can be retrieved via XPath.

HasXPath Method (Odata Component)

Determines whether a specific element exists in the document.

Syntax

public boolean hasXPath(String XPath);

Remarks

This method determines whether a particular XPath exists within the document. This may be used to check if a path exists before setting it via XPath.

This method returns True if the xpath exists, False if not.

See XPath for details on the XPath syntax.

QueryService Method (Odata Component)

This method queries an OData service using the specified parameters.

Syntax

public void queryService();

Remarks

This method queries an OData feed specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath) using the query options specified in the Query*** properties and OtherQueryOptions. To fetch an OData feed, without performing any filtering, you can leave Query*** and OtherQueryOptions empty and call QueryService.

The query results are delivered in the TransferredData property, as well as through the Transfer event. The response headers can be retrieved through the ParsedHeaders property as well as through the Header event.

The component will attempt to parse the query results. Upon successfully parsing the response, Channel will be set with their associated feed element values and EntryCount will be populated with the total number of entries contained within the feed. EntryIndex will also be set to 1, thus populating EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, EntryProperties, and ResourcePath.

Reset Method (Odata Component)

This method resets all of properties of the component.

Syntax

public void reset();

Remarks

The Reset method resets all properties to the component's default settings. This is an easy way to clear all of the property values before repopulating the OData feed.

SetEntryProperty Method (Odata Component)

This method is used to set an OData entry property.

Syntax

public void setEntryProperty(String XPath, String value);

Remarks

This method is intended to extend functionality of the OData component and will set the value of the entry property (specified by XPath) to the specified Value. Therefore, the value of the corresponding property will be updated within EntryProperties.

XPath is the XPath of the element or attribute according to the following convention: entry[x]/element. When EntryIndex is set to an index greater than or equal to zero, a relative path can also be used: property. When a relative path is specified, the component will use the specified EntryIndex along with the property specified to update the EntryProperty value.

entry[x] is the feed's xth entry (or any other root-level child), where the indexer x starts at 1.

property is any child of the property's element.

Example 1. Set Properties: ODataControl.SetEntryProperty("entry[5]/content/properties/Name", "MyNewName") Example 2. Retrieve Properties:

The following example uses a relative path to retrieve properties of the first feed entry: ODataControl.EntryIndex = 1 ODataControl.SetEntryProperty("Name", "MyNewName") ODataControl.SetEntryProperty("Address/State", "NC")
