title: AFHTTPSessionManager add body to POST
body: <p>I need too make a post request to my server.</p>
  
  <p>With <strong>AFHTTPRequestOperation</strong> is very simple just use:</p>
  
  <pre><code>[request setHTTPBody: [requestBody dataUsingEncoding:NSUTF8StringEncoding]];
  </code></pre>
  
  <p>However i can't find any example how use the same approach using the <strong>AFHTTPSessionManager</strong>.</p>
  
  <p>Using the method:</p>
  
  <pre><code>[self POST:@"extraLink" parameters:nil constructingBodyWithBlock:^(id&lt;AFMultipartFormData&gt; formData) {
  
  } success:^(NSURLSessionDataTask *task, id responseObject) {
  
  } failure:^(NSURLSessionDataTask *task, NSError *error) {
  
  }];
  </code></pre>
  
  <p>How i add the the body to the "AFMultipartFormData"?</p>
  
  <p>Thanks in advace</p>
