GET Service

Function:

The tool GET provides support for you to execute a HTTP GET request on a Web application to get resources from a Web application.

Tool Attribute:

Attribute	Type	Description
Media Type [M]	Selection	Specifies the media type that is acceptable for the response. Valid values are: application/json (default) application/octet-stream Note: If the accepted media type is specified via a Request Header with the key "Accept", the header value has preference. Click here for more information on header field definitions.
Response Body Resource Processing [O]	Selection	Specifies what type of resource operation should be executed based on the returned response body. The resource operation uses all properties mapped in the referenced response body output parameter file descriptor. Optional, not all resource operation types require property values to be successfully executed, for example, DELETE will remove the selected element even if no element ID properties are specified. Attribute values: COPY DELETE INSERT INSERT_CHILD MOVE REFRESH UPDATE See Tool Descriptor for more information on resource processing. Note: The Resource Processing attribute of the tool descriptor must be set to TOOL_DEFINED in order for the resource operation to be processed.

Description

Media Type [M]

Selection

Specifies the media type that is acceptable for the response. Valid values are:

application/json (default)
application/octet-stream

Note: If the accepted media type is specified via a Request Header with the key "Accept", the header value has preference. Click here for more information on header field definitions.

Response Body Resource Processing [O]

Selection

Specifies what type of resource operation should be executed based on the returned response body.

The resource operation uses all properties mapped in the referenced response body output parameter file descriptor. Optional, not all resource operation types require property values to be successfully executed, for example, DELETE will remove the selected element even if no element ID properties are specified.

Attribute values:

COPY
DELETE
INSERT
INSERT_CHILD
MOVE
REFRESH
UPDATE

See Tool Descriptor for more information on resource processing.

Note: The Resource Processing attribute of the tool descriptor must be set to TOOL_DEFINED in order for the resource operation to be processed.

For example, a GET request for obtaining information about a project entry with Response Body Resource Processing set to UPDATE will refresh the property values of a selected project entry.

Parameters:

Parameter Name	I/O	Type	Description
URL [M]	I	String	URL to the GET service of the Web application
Realm [O]	I	String	Realm enables mapping between client application and Web application. It is only relevant if an AWM application addresses different Web applications.
Request Body [M]	I	File	File containing the get payload as expected by the Web application.
Response Body * [O]	O	File	File containing the get response sent from the server application.
Response Code [O]	O	String	Response Code returned by the server application.
Response Header * [O]	O	String	Reference to a response header field of the HTTP GET request.

Additional Parameter Attributes:

Parameter Name	Attribute	Description
URL	Query Encoding	Charset used to encode the URL.
	Query Separator Symbol	Symbol used to separate query parameters within the URL string.
Response Body	Status Code	Status code which can be intercepted by a custom error handling. Note: This must be specified as regular expression.
Response Header	Name	Name of the response header field.

Relationship: REST Tool Has Request Header

The relationship REST Tool Has Request Header enables you to specify a name/value pair to be sent in the HTTP request header.

If specified in an authentication request the name/value pair is sent with every HTTP request for the signed in session.

Attribute	Type	Description
Name	String	Name of the HTTP header field.
Value	String	Value of the HTTP header field.

Relationship: URL Has Query Parameter

The relationship URL has Query Parameter that enables you to specify parameters in the form of name/value pairs to be added to the HTTP request.

Attribute	Type	Description
Name	String	Name of the query parameter.
Value	String	Value of the query parameter.

Relationship: REST Tool Has Status Handler

The relationship REST Tool Has Status Handler enables you to specify the handling of certain status codes returned by the tool. It overwrites a general handling of the status codes defined under the REST connection.

Attribute	Type	Description
Allow Loop [M]	Boolean	Specifies whether the status handler can call an action which contains the tool for which the status handler is defined. Attribute values are: true The status handler can execute the action specified in the Perform Action, even if this contains the REST tool for which the status handler is defined. false The status handler stops executing when a cyclic execution is detected when the action specified in the Perform Action is called. The default value is true.
Max Loop Count [O]	Integer	Specifies the maximum number of loop cycles when a loop is detected. The default value is 3. Note: This attribute is only relevant when the attribute Allow Loop is set to true. In this case, the action specified under the attribute Fail Action is executed as soon as the maximum loop count is reached.
Fail Action [O]	Action Descriptor	Specifies the action to be executed if the maximum loop count is reached in case of a cyclic execution. This attribute is only relevant when the attribute Allow Loop is set to true.
Response Code Pattern [M]	String	Specifies the response code(s) to be handled by this status handler. Must be specified as a regular expression.
Perform Action [M]	Action Descriptor	Specifies which action should be performed when the status handler is triggered.
Structure Descriptor [O]	File Descriptor	File containing the structure for the response that is specific for the matched status code.
Workflow Execution [M]	Selection	Specifies the impact on the original action of the handled REST tool. It describes how the action containing the REST tool is continued after the status handler action specified under the attribute Perform Action was executed. Attribute values are: Stop Execution Stop the execution of the action that executes the REST tool. Execute Tool Again Execute the REST tool again and continue the execution of the action. Continue Execution Continue the execution of the action.

Example

The following example shows a tool that gets the regions of an Enterprise Server:

The file descriptor that describes the response body can be modelled as follows:
