Swift 3请求帖子，回复返回无

问题描述：

我有帖子请求和解析响应json代码，但我的代码不工作。Swift 3请求帖子，回复返回无

我的类代码

@discardableResult 
    open func getLoginMethod(_ method: String, parameters: String, completionHandler: @escaping (_ login: [Login]?, _ error: Error?) -> Void) -> URLSessionTask! { 
     let session = URLSession.shared 
     guard let url = NSURL(string: parameters) else { 
      completionHandler(nil, myErrors.InvalidUrlError) 
      return nil 
     } 

     let request = NSMutableURLRequest(url: url as URL) 
     request.httpMethod = "POST" 
     let sendingdata = "Simple=1" 
     request.httpBody = sendingdata.data(using: String.Encoding.utf8); 

     let task = session.dataTask(with: request as URLRequest) { data, response, error in 

      if error != nil { 
       completionHandler(nil, myErrors.getError) 
      } else { 
       do { 
        let login = try self.getLogin(jsonData: data! as NSData) 

        print(login) 

        completionHandler(login, nil) 
       } catch { 
        completionHandler(nil, error) 
       } 
      } 
     } 
     task.resume() 

     return task 
    }

当我点击动作按钮的代码给我只能

零

输出。我在哪里做错了任何想法？

@Vinodh耶确保模型的代码实现。我认为request.httpBody = sendingdata.data错误（使用：String.Encoding.utf8）;或如果让jsonArray =尝试JSONSerialization.jsonObject（与：jsonData作为数据，选项：.allowFragments）为？ [字符串：AnyObject] { – SwiftDeveloper

@Vinodh我也加入了登录模式 – SwiftDeveloper

@Vinodh nope仍然相同 – SwiftDeveloper

请找到下面的代码使用我这是工作的罚款与当地son.Since你没有提供网址和其他细节

if let file = Bundle.main.path(forResource: "response", ofType: "json") { 
       do { 
        let jsonData = try Data(contentsOf: URL(fileURLWithPath: file)) 
        let login = try self.getLogin(rawData: jsonData) 

        let arr = login.first 

        if let date = arr?.ServerCurrentDate { 

         print("Comming Date = \(date)") 


        } 

       } 
       catch{ 
        print(error) 
       } 
      } 


private func getLogin(rawData: Data) throws -> [Login] { 
     var login = [Login]() 

     do { 
      if let jsonDict = try JSONSerialization.jsonObject(with: rawData, options: .allowFragments) as? [String: AnyObject] { 
       print(jsonDict) 
       if let result = jsonDict["Result"] as? [String : AnyObject] 
       { 
        var properties = [String: AnyObject]() 
        properties["IsSuccess"] = result["IsSuccess"] as? Bool as AnyObject? 
        properties["MemberId"] = result["MemberId"] as? Int as AnyObject? 
        properties["Name"] = result["Name"] as? String as AnyObject? 
        properties["Image"] = result["Image"] as? String as AnyObject? 
        properties["FacebookId"] = result["FacebookId"] as? Int as AnyObject? 
        properties["FacebookMail"] = result["FacebookMail"] as? String as AnyObject? 
        properties["Phone"] = result["Phone"] as? String as AnyObject? 
        properties["Code"] = result["Code"] as? String as AnyObject? 
        properties["Token"] = result["Token"] as? String as AnyObject? 
        properties["ServerCurrentDate"] = result["ServerCurrentDate"] as? String as AnyObject? 
        let loginget = Login(properties: properties) 
        login.append(loginget) 
       } 

      } 
     } catch { 
      print(error) 
     } 
     return login 
    }

而且我的本地JSON文件

response.json

{ 
    "Result": { 
     "IsSuccess": true, 
     "MemberId": 73, 
     "Name": "X4r-7a", 
     "Image": "MemberImage/48a25240-26a9-46bf-8eb5-72a6b86ad555.png", 
     "FacebookId": null, 
     "FacebookMail": null, 
     "Phone": "0111111112", 
     "Code": "5425", 
     "Token": "570f4112-0f37-4e23-a2d7-5dad6af9378a", 
     "ServerCurrentDate": "2016-11-23-10-41-32" 
    } 
}

@Vinodth ty男人请批准编辑。你的代码与真正的json文件一起工作，但我认为我有服务器端问题。 – SwiftDeveloper

你只有我给了这个回应，所以我用它。 – Vinodh

答

你的值是一个更深一步的JSON结构：

... 

if let result = jsonDict["Result"] as? [String : AnyObject] 
{ 
    properties[LoginJsonKeys.Name] = result["Name"] as? String 
} 
...

希望帮助

是的，我将它添加到我的课程代码中，就像你展示的一样，但是当输出结果相同时结果是零。 – SwiftDeveloper
