Add header to every request in Postman in pre-request script

Question

I want to automatically add a header to every request in my whole collection using this pre-request script:

pm.request.headers.add({
    \'key\': \"myvar\",
             


        

Answer 1

In test section of login, use this script to remember token in Environment

var jsonData = JSON.parse(responseBody);

tests["Body contains result"] = responseBody.has("result");

var result = jsonData.result

tests["result contains user"] = result.user !== null
var user = result.user
tests["result contains token"] = result.token !== null
var token = result.token
var accessToken = token.accessToken
var refreshToken = token.refreshToken

postman.setEnvironmentVariable("accessToken", accessToken);
postman.setEnvironmentVariable("refreshToken", refreshToken);

in every call wihich requires token, use token like this in header section

Authorization = Bearer {{accessToken}}
