HTTP verb functions

HTTP verb functions

Use HTTP verb functions to retrieve the HTTP verb and the resource path segments that are used in a request. The HTTP verb functions are available under the
Request Context
 section of the Expression Editor.
You can use the following HTTP verb functions:
getRequestHTTPVerb
Use the
getRequestHTTPVerb
 function to determine the HTTP verb that is used in a request. The function retrieves the HTTP verb from the request and returns one of the following responses in a string format:
  • GET
  • POST
  • PATCH
  • PUT
  • DELETE
getResourcePathSegments
Use the
getResourcePathSegments
 function to retrieve all or specific resource path segments of REST requests. The function returns the values as a string of tokens.
For example, consider the following request URL:
https://na1.ai.dm-us.informaticacloud.com/active-bpel/rt/InitiateOrder/Orders/OrderID_100/quantity/5
If you use the
request:getResourcePathSegments()
 expression, you see the following response:
[Orders, OrderID_100, quantity, 5]
To retrieve a specific resource path segment, use a numeric qualifier to denote the position of the resource path segment from the process name.
For example, to retrieve the
OrderID_100
 segment alone in the response, use the following expression:
request:getResourcePathSegments()[2]
You cannot use the
getResourcePathSegments
 function to fetch the resource path segments of SOAP requests and message events. You cannot use the
getResourcePathSegments
 function to fetch the host context.
