Layer7 API Management

Hello, 

If the incoming request method to proxy url (created through CA API Gateway) is GET, then I can play around with the context variables using ${request.http.parameters}. However if the request type is POST and I need to edit the request body and add some extra content (e.g. date) before passing on to the back-end service, then how to do it? I tried using ${request.http.body}/${request.body} etc. but while debugging it always showed null.

Please suggest.

Hi Pramod,

The request body is available in the variable: ${Request.mainpart}.

I.e: If I posed a username and password

username=joe&password=test

Request.mainpart will be equal to username=joe&password=test

If you need to grab a specific parameter, ie: username you could use:

${request.http.parameters.username}

Hope this helps.

Regards,

Joe

Hi Joe, 

I am testing on Postman where I add two parameters to a request body and then start Policy Manager in the Debug mode. However, ${Request.mainpart} is still null 

Is the example of username=joe&password=test for Get method or Post ?

Thanks, It worked.

Glad to hear... Just for completeness here.. yes it was from an HTTP POST.
