  • 1.  Switch condition on Context Variable

    Posted 11/23/21 09:33 PM
    Hi, 
    In API Connect (v10.0.3 - API Gateway), I am trying to define a switch condition based on the context variable that I have defined in the previous gateway-script. context.set('id', '2');

    In below example, I am checking for the value of 'id' when set as a header, and this works fine. 

    1. How can I do the same when the 'id' is set as a context variable? 
    2. How can I do this when 'id' is set within a JSON body ({"id": 2}) defined within a context variable?

          - switch:
              version: 2.0.0
              title: switch
              case:
                - condition: ($header("id") = '2')
                  execute: []

    Hi Romil,

    Referencing the context variable directly is all that is needed

          - switch:
              version: 2.0.0
              title: switch
              case:
                - condition: (id = '2')
                  execute:
                   ...
    Regards,
    Steve

    Thanks Steve, this worked. Directly using the variable name was probably the only thing I didn't try before  :)
    Really appreciate the help.

    Hi @Steve Linn ,

    I request your help in the below issue , Please guide me.

    I am trying to set a runtime variable which I want to access in the set variable policy just after my gateway script , In my gateway script I have mentioned below code :

    var originalAPIpath = "/proposalservice/v2/proposal";
    var APIpath = originalAPIpath.replace("/proposalservice/v2", "");
    context.set('APIpath', APIpath);

    But I am getting an exception while doing this and it says in Datapower logs :

    apim.gatewayscript: ReferenceError: context is not defined

    Could you please let me know what I am doing wrong?
    Also I will be accessing the variable APIpath in the set variable policy below , is it correct?


    Thanks
    Adarsh

    Hi Adarsh,

    Is your posted code in a function?  This could be a scoping issue where the function does not know variable context.  It should be available implicitly in your mainline code but is not global to the entire gatewayscript code.  If within a function you should simply pass context as an argument to your function.  If your code is in the mainline of your code, the only thing I can think of is your gatewayscript policy is a version 1.0.0 which doesn't support the context variable.

    Regards,

    Steve
