Getting Auth Tokens

Send a login request to get an authorization token for the rest of your test

You are now browsing the LoadForge locust test directory. You can use these tests as a starting point for your own tests, or use our AI wizard to generate one automatically.



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

These are snippets!

These are just partial examples from a test. You may use the wizard or another example template and copy paste these into your test.

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

Locust Test Example

LoadForge is powered by locust, meaning open source locust users can copy this script as well. If you are a locust user, consider importing your script to LoadForge to supercharge your testing!
