Setting value from Headers as environment variable

[docking-module-tech5 (Artur)]

Hello,

I’m setting environment variable from Body response like this:

var response = JSON.parse(responseBody);
pm.environment.set("variable", response.body_parameter);

But I would like to do same thing with value from Headers e.g to set “content-length” value as environment variable:

Could you please advise?

Access Response Headers with Postman Tests

Hi, Is there a way to access the Response Headers with a Postman test? I am making a call to check the Status of a website, but would also like to console log the Server and Content-Type values that are returned. thanks for any insights

Hi @docking-module-tech5

You can try as below

var contentLength = JSON.stringify(pm.response.headers); 

console.log(contentLength);

pm.environment.set('contentLength', JSON.parse(contentLength)[2].value);

console.log(pm.environment.get("contentLength"));

If you’re interested in getting this value as a one-liner, you can retrieve the headers with pm.response.headers and then use the HeaderList syntax to grab the specific header by name:

pm.environment.set("contentLength", pm.response.headers.get("Content-Length"));
