Getting Auth Tokens

Certain applications require a request in order to get an authentication token. This is common with APIs or SPAs.

With LoadForge you can easily set any headers you need by tweaking your get() or post() calls to include a header set. You can see REST api examples for more examples.

Below is a partial test (just the on_start section) that shows how to set an authorization (or really any) header based on response content at launch with your load test.

Naturally, you would not do all of these. They are 3 examples of getting a Bearer token in different ways.

Code snippets

from locust import HttpUser, TaskSet, task
import requests


class UserBehavior(TaskSet):
  def on_start(self):


  	  # Send login request
      response = requests.post("http://mysite.com/login", {
        "username": "user",
        "password": "pass"
      })


      # THEN set "token" from response header
      self.client.headers.update({'Authorization': response.headers.get('token')})


      # OR set "token" from response cookies
      self.client.cookies.set('Authorization', response.cookies.get('token'))


      # OR set "token" from response body
      token = str(response.content.decode().find('token')
      self.client.headers.update({'Authorization': token)})


  # continue the rest of your test
