Alamofire API请求因responseSerializationFailed在Swift 3中失败 [英] Alamofire API request is getting failed with responseSerializationFailed in swift 3

问题描述

我正在使用Alamofire调用普通的API调用，并且没有在网络管理器类中传递任何数据。

I am calling normal API call with Alamofire, And I am not passing any data with that in networking manager class.

我的网络类是

func executeGetRequest(url:String,requestVC:UIViewController,completionHandler:@escaping (_ responseObject:Any?) -> Void!,failureHandler:@escaping (_ connectionError:NSError?) -> Void!){

    //Checking internet alert
    if !self.isConnectedToInternet(){
        // requestVC.showAlert(kText_AppName, message: kText_NoInternet)
        return
    }

    requestVC.showLoader()
    Alamofire.request(url).responseJSON {
        (response:DataResponse) in

        requestVC.removeLoader()

        switch(response.result) {
        case .success(_):
            if response.result.value != nil{
                completionHandler (response.result.value)
            }
            break

        case .failure(let error):
            failureHandler (error as NSError?)
            break

        }
    }
}

我是从我的主要班级来称呼它的

and i am calling it from my main class

kNetworkManager.executeGetRequest(url: kAppAccessTokenURL, requestVC: self, completionHandler: {
     (responseObject) -> () in
          print("responseObject:\(responseObject!)")


      }, failureHandler: {(error)-> () in
          print("response object:\(error!)")
          self.showAlert(message: (error?.description)!, title: kText_AppName)
          if error?._code == NSURLErrorTimedOut {
                //timeout here
                self.showAlert(message: kText_timeout, title: kText_AppName)
           }
      })

总是获取请求失败，并显示错误为 responseSerializationFailed

Its getting always request fail and showing error as responseSerializationFailed

如果我直接在Main class中直接调用，而没有

if I call directly in Main Class without manager class like

Alamofire.request(kAppAccessTokenURL).responseString { response in

中的响应

我能够获得响应，任何人都可以建议我在网络课程中哪里出错了。

I am able to getting response, can anyone suggest me where getting wrong in Network class.

推荐答案

在这里

Alamofire.request(kAppAccessTokenURL).responseString

还有

 Alamofire.request(url).responseJSON

期待那个

     let jsonText = "{\"first_name\":\"Sergey\"}"
        var dictonary:NSDictionary?

        if let data = jsonText.dataUsingEncoding(NSUTF8StringEncoding) {

            do {
                dictonary =  try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String:AnyObject]

                if let myDictionary = dictonary
                {
                     print(" First name is: \(myDictionary["first_name"]!)")
                }
            } catch let error as NSError {
                print(error)
            }
        }
