title: Swift 2 - POST requests don't get parameters added
body: <p>Following up to a question someone asked on the Alamofire github issues that never got answered because I want the answer as well. </p>
  
  <blockquote>
    <p>Doing a simple request with GET adds my parameters nicely, but doing a
    POST doesn't.</p>
  
  <pre><code>let parameters = ["foo": "bar"]
  
  Alamofire.request(.POST, "url", parameters: parameters)
  .responseJSON { request, response, json, error in
    print("request: \(request)")
  }
  </code></pre>
    
    <p>returns</p>
  
  <pre><code>request: Optional(&lt;NSMutableURLRequest: 0x7f9864109cb0&gt; { URL: https://api.github.com/repos/BasThomas/junk/issues })
   while
  
  let parameters = ["foo": "bar"]
  
  Alamofire.request(.GET, "url", parameters: parameters)
  .responseJSON { request, response, json, error in
    print("request: \(request)")
  }
  </code></pre>
    
    <p>returns</p>
  
  <pre><code>request: Optional(&lt;NSMutableURLRequest: 0x7f9ef07ef0f0&gt; { URL: https://api.github.com/repos/BasThomas/junk/issues?foo=bar })
