Response element to +1 on every request

  • 1.  Response element to +1 on every request

    Posted 01-20-2020 07:34 AM
    Hello,
    I want to see number of requests and they should be tracked in response.

    {
    "requestnumber": 1
    }

    Everytime there is a new request, requestnumber should add 1 and give the same in response.
    Please help on how to achieve this.

    Hi,

     

    How "persistent" does this requestnumber have to be (the more persistent, the more difficult to implement).

    Is it ok if it is reinitialized when the virtual service is redeployed?

    Or is it ok when it is reinitialized when the VSE is recycled?

    Or does it need to be stored outside the SV platform such that it never reinitializes (until you specifically reset it)

     

    Is the "requestnumber" on the level of virtual service, ie. only one number even if there are many different transactions in your vsi?

    Or is the "requestnumber" on the level of the (specific) transactions?

     

    Cheers,

    Danny

    This is at each transaction level. Every time there is a new hit to the request URL, requestnumber should add 1 and give as response.

    Hi,

     

    I guess there are many ways to solve this, here is something that could work.

     

    I made an assumption: this is a REST interface that is being virtualized, right? (because for SOAP interface the URL doesn't change for different transactions)

     

    Your requirement seems to suggest a 1-to-1 relationship between URL and transaction. In the vsi a transaction has a 1-to-1 relationship with a signature but not necessarily with the URL. For one URL there can exist more than one signature, specifically with POST requests.

     

    Below is an implementation that counts requests for the same URL, ie. the operation of the signature is the identifier for the count.

     

    Add a scriptable step between "VS Image Response Selection" and "Virtual HTTPS Responder", add following script:

     

           int request_number = 0;

           String request_id = "count " + lisa_vse_request.getOperation();

           String strNumber = null;

           strNumber = testExec.getStateValue(request_id);

           if (strNumber != null))

           {

               request_number = Integer.parseInt(strNumber)

           }

           request_number++;

           testExec.setStateValue(request_id, request_number);

     

     

    In your vsi, your responses should contain:

     

    {
    "requestnumber": {{request_number}}
    }

     

    Cheers,

    Danny

    Hi Danny,

    Your understanding is absolutely right. This is a REST service and with POST method.
    Request you to clarify what do you mean by "

    Add a scriptable step between "VS Image Response Selection" and "Virtual HTTPS Responder""
    I am not able to find option to add scriptable step after VS Image Response Selection, I have attached print screen.

    Raghu!!

    This printscreen should guide you:

    Hi Danny,

    I have added the script. However, it is not returning number in the response, instead is giving as below.
    {
        "requestnumber": {{request_number}}
    }

    Inspection view log message says " THINK for 911"

    Indeed, apologies, there was one statement missing at the end, the  property request_number itself was not added to the test execution environment:

     

           int request_number = 0;

           String request_id = "count " + lisa_vse_request.getOperation();

           String strNumber = null;

           strNumber = testExec.getStateValue(request_id);

           if (strNumber != null))

           {

               request_number = Integer.parseInt(strNumber)

           }

           request_number++;

           testExec.setStateValue(request_id, request_number);

           testExec.setStateValue("request_number", request_number);

     

     

    Cheers,

    Danny

    Hi Danny,

    It is working with first hit, but not giving +1 response for next requests. It is giving response as below again
    {
        "requestnumber": {{request_number}}
    }

    Thanks for the log, that helps.

     

    The fourth statement, can you add the casting to String so that it becomes:

     

    strNumber = (String) testExec.getStateValue(request_id);

     

     

    Cheers,

    Danny

    Ok, apologies, doing this from top of head without help of Eclipse's semantic checking.

    Did you change the initialization of request_number to "1234567"? (if you did not then something strange happened)

     

    Please change statement 4 back to what is was, ie:

     

    strNumber = testExec.getStateValue(request_id);

     

    And change the second to last statement to:

     

    testExec.setStateValue(request_id, String.valueOf(request_number));

     

     

    The whole should look like:

     

    int request_number = 0;

    String request_id = "count " + lisa_vse_request.getOperation();

    String strNumber = null;

    strNumber = testExec.getStateValue(request_id);

    if (strNumber != null)

    {

        request_number = Integer.parseInt(strNumber)

    }

    request_number++;

    testExec.setStateValue(request_id, String.valueOf(request_number));

    testExec.setStateValue("request_number", request_number);

     

     

     

     

    Cheers,

    Danny

    Oh, and there is a semi-colon missing at the end of the statement in the if-block

     

                  request_number = Integer.parseInt(strNumber);

    Hi Danny,

    I had changed this to "12345678" as per requirement. This script worked and respective results are achieved.
    Thank you very much for your fantastic support and time taken to resolve my query.

    Raghu!!
