title: How can I return the json property of this swiftHTTP function as a string?
body: <p>I am trying to learn how to use swiftHTTP with a mishap api (<a href="https://www.mashape.com/textanalysis/textanalysis" rel="nofollow">https://www.mashape.com/textanalysis/textanalysis</a>). This is my code so far,</p>
  
  <pre><code>import SwiftHTTP
  
      func splitSentenceIntoWordsUsingTextAnalysis (string: String) -&gt; String {
      var request = HTTPTask()
      var params = ["text": "这是中文测试"] //: Dictionary&lt;String,AnyObject&gt;
      //request.requestSerializer = JSONRequestSerializer()
      request.requestSerializer.headers["X-Mashape-Key"] = "My-API-Key"
      request.requestSerializer.headers["Content-Type"] = "application/x-www-form-urlencoded"
      request.responseSerializer = JSONResponseSerializer()
      request.POST("https://textanalysis.p.mashape.com/segmenter", parameters: params, success: {(response: HTTPResponse) in if let json: AnyObject = response.responseObject { println("\(json)") } },failure: {(error: NSError, response: HTTPResponse?) in println("\(error)") })
  
  // {
  // result = "\U4f60 \U53eb \U4ec0\U4e48 \U540d\U5b57";
  // }
  
  return ?? // I want to return the "result" in the json as a string.
  
  }
  </code></pre>
  
  <p>How can I return the "result" in the json as a string?</p>
