ios - Swift 3 请求 post ，响应返回 nil

Question

我有发布请求和解析响应 json 代码，但我的代码不起作用。

我的类(class)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
    }

当我点击代码只给我的操作按钮时

nil

输出。我哪里做错了什么？

您的值在 json 结构中更深了一步:

... 

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

希望对你有帮助
