Trying using Check and capturing dynamic values in gatling 2

[vikas bajaj]

Hi 

I am trying to capture one dynamic value which gets generated while rent/buy  business process  in my application.

body=

{"ResultInfo":{"ResultCode":"0","ActivityID":"2bfe5e94-6ce0-4fe3-98dc-f645a1334d68","MachineID":"miagrbiwebwb02v.stg.rbi.local"},"OnDemandCartPricing":{"Price":"16.99","Tax":"1.40","Total":"18.39","ConfirmationID":"602571651

I need to pass this confirmation ID to the below subsequent request to be able to  succesfully rent a movie inmy application. I am trying  different option like regex with check but everything fails. can  some one help me,

Here is the code

.pause(2)

.exec(http("request_189")

.post("https://stg.redboxinstant.net:443/rbproxy/api/GetOnDemandCartPricing")

.headers(headers_16)

.queryParam("""_""", "1396459963878")

.fileBody("RecordedSimulation_request_189.txt")

.check(headerRegex("ConfirmationID :").saveAs("ConfirmatonID"))

First, you're trying to find something in the response BODY while you're trying to use a regex on the HEADERS.

Then, JsonPath is probably more suited that regex for this use case: https://github.com/excilys/gatling/wiki/Checks#json

Hi Stefnie.

Thanks for the reply. I am quite new to this tool and have been working from last few weeks to  reocrd our web application and replay back with concurrent users. we are able to reocord  the application and replay is also working  except couple of correlations needs to take care to make it more dynamic.

i have tried going to the above link posted by you but couldn't capture the value. can you please help me  writing one function  how to extract the  dynamic value   from the code   shown below and i can use that in my subsequent request and i can then go ahead and  apply my thoughts  to other correlation

body=

{"ResultInfo":{"ResultCode":"0","ActivityID":"2bfe5e94-6ce0-4fe3-98dc-f645a1334d68","MachineID":"miagrbiwebwb02v.stg.rbi.local"},"OnDemandCartPricing":{"Price":"16.99","Tax":"1.40","Total":"18.39","ConfirmationID":"602571651"

I am trying to capture the confirmation ID value ( 602571651) which is dynamic and comes out  different   for each transaction.

[Stéphane Landelle]

Yep, I already got it last time.

Still, have you read the documentation I pointed last time?

[vikas bajaj]

Yes. I am using the below check.

.check(regex(""""ConfirmationID":"([^"]*)""").saveAs("ConfirmationID")) which is not working currently and i ma getting Http 405 error.

=========================

May be i am placing the .check at the wrong place.?

Thanks

I don't know what you're doing.

405 Method Not Allowed means that you're sending a request with an inappropriate method, such as sending a POST instead of a GET.

Once you've figured this out, please post a gist of your code:https://gist.github.com

i am doing a POST  as it got captured  in the code also and i am very familiar with my application and i know it should be POSt as we are load testing with load runner too and it is working perfectly there.

we are just trying to see if we can replace  load runner with gatling for our application load testing.

[vikas bajaj]

i am doing the  login flow for now and let you know if  i go through that. it would be easy to mov forward once we have login working

[Santosh Kulkarni]

Have you implemented the correlation ? Please let me know.

Thanks,
Santosh

Try to remove charset=UTF-8 from content type header...
