title: Disable SSL certificate check Twisted Agents
body: <p>I am using Twisted (16.3) and Treq (15.1) to make async requests in Python (2.7). </p>
  
  <p>I am having issues with some requests over HTTPS.</p>
  
  <p>Some sites have an invalid certificate and thus when making a request to them, I get this:</p>
  
  <pre><code>twisted.python.failure.Failure OpenSSL.SSL.Error
  </code></pre>
  
  <p>I want my client to trust any server, including those without certificates or with self signed certificates.</p>
  
  <p>How can I disable certificate checks on my client?</p>
  
  <p>This is a question essentially identical to mine: <a href="https://stackoverflow.com/questions/34357439/ssl-options-for-twisted-agents">https://stackoverflow.com/questions/34357439/ssl-options-for-twisted-agents</a></p>
  
  <p>Thanks!</p>
