title: AFNetworking - How can I PUT and POST raw data without using a key value pair?
body: <p>I am trying to make an HTTP PUT request using <code>AFNetworking</code> to create an attachment in a CouchDB server. The server expects a base64 encoded string in the HTTP body. How can I make this request without sending the HTTP body as a key/value pair using <code>AFNetworking</code>? </p>
  
  <p>I began by looking at this method:</p>
  
  <pre><code>- (void)putPath:(NSString *)path
   parameters:(NSDictionary *)parameters
      success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
      failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;
  </code></pre>
  
  <p>But here the parameters are to be of type: <code>NSDictionary</code>. I just want to send a base64 encoded string in the HTTP body but not associated with a key. Can someone point me to the appropriate method to use? Thanks!</p>
