Access JSON response from Service Callout in Javascript

Google Cloud Apigee
1

HI,

I have a ServiceCallout policy which returns a JSON object as a response in a variable called otpresponse.

The response looks like this.

{“sessiontoken”:“776f1f1b311ddec7”,“counter”:309998532595415141}

I want to access these variables individually in the Javascript policy.

I tried using this but in vain

context.setVariable(“otp”, context.getVariable(‘otpresponse.content.sessiontoken’));

How can I fetch the variables individually in a Javascript?

@apigee1234567 , It should work out of the box. Please use trace console to debug same.

Hello @Anil Sagar

Thanks for your reply. It is not working.

If I write ontext.setVariable(“otp”, context.getVariable(‘otpresponse.content’));, I get the entire response in JSON form.

But I require to fetch individual values in the JSON, which I am not when I write otpresponse.content.sessiontoken

I thought that the JSON elements cannot be extracted directly within a JS using context.getVariable(). We can alternatively use Extract variable policy and extract using Jsonpath.

Here is what I did when i needed JSON element in JS - var payload = context.getVariable(“otpresponse.content”); var jsonObject= JSON.parse(payload); var otp = jsonObject.sessiontoken;
