从我的应用程序工作MassPay侦错码至贝宝与SWIFT

func payPalMassPayOutMessage() {

     do { 

      postsUrlRequest.HTTPBody = paymentString.dataUsingEncoding(NSUTF8StringEncoding) 

     let config = NSURLSessionConfiguration.defaultSessionConfiguration() 
     let session = NSURLSession(configuration: config) 

     let createTask = session.dataTaskWithRequest(postsUrlRequest, completionHandler: {

     guard let responseData = data else {

     guard error == nil else { 
      print("error calling post ") 
      print(error) 
      return 
     } 



     guard let dataSring = NSString(data: data!, encoding: NSUTF8StringEncoding) else { 
      print("error parse dataString ") 
      return 
     } 
     print("response data \(dataSring)") 

    }) 
     createTask.resume()
