在swift中使用块丢失数据

Question

当我试图从服务器获取正确返回的数据时在控制台上打印整个json，但当我在json上徘徊时获得半个json。那么请你告诉我它是怎么回事。如果有人可以帮助我，那将是很好的，在此先感谢。

我的要求是

    let clientApi   : NapaClientAPI = NapaClientAPI.sharedInstance
    clientApi.fetchDataFromServer("URL", parameters:dataDic, success: {(response, error) -> Void in
           println(response)
    }) {(error) -> Void in
         println(error?.description)
    }

在此处获得回复

    Alamofire.request(.POST, apiURL, parameters: parameters, encoding: .JSON).responseJSON { (req, res, json, error) in
                println("Json === \(json)")
                println("Error ===\(error)")

                if json != nil{
                    success(response: json, error: nil)
                }
                else{
                    failure(error: error)
                }

            }

输出：

**Json** === Optional({
    response =     {
        Contacts =         (
                        {

        message = success;
        "response_code" = 200;

    }; })

**Error** ===nil
