body: <p>I provide number of users=12 and hatch rate=2.
  How can I get user id(s) of all users hitting my web page, as I would like to do some customizations based on the object names which are getting created (say an article title).</p>
  
  <p>How to pass user information (say user id) while creating new articles. So that if I run a test with 12 users, I would know that articles were created by a certain user.</p>
  
  <pre><code>from locust import HttpLocust, TaskSet, task
  
  def create_new_article(self):
         with self.client.request('post',"/articles",data={"article[title]":"computer","article[content]":"pc"},catch_response=True) as response:   
         print response
