Alamofire POST请求不改变头

Question

我读了关于Alamofire POST请求我设法implemenet它为我的使用文档后，但POST请求保持返回我的代码400，这意味着该请求是坏的。

Following steps here

我的实现看起来LIK：

let parameters = ["username": name, "password": hashPass] 
     let url = URL(string: LOGIN_URL)! 
     var request = URLRequest(url: url) 
     request.httpMethod = "POST" 
     do { 
      request.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: []) 
     } catch { 

     } 
     request.setValue("application/json;charest=utf-8", forHTTPHeaderField: "Content-Type") 

     Alamofire.request(request).responseJSON { response in 
      print("Get default graph request \(response.request!)") 
      print("Get default graph response \(response.response!)") 

      if let message = response.result.value { 
       SessionMenager.Instance.token = message as! String 
       completion(true) 
      } else { 
       completion(false) 
      } 
     } 

每当我调试代码，我可以看到"Content-Type" = "text/html"。

我怎么能解决这个问题？ 在此先感谢！

这里是URLSession一个版本，它的工作原理：

let stringOp = StringOperations.init() 
      let md5Data = stringOp.MD5(string:pass) 
      let hashPass = md5Data!.map { String(format: "%02hhx", $0) }.joined() 

      let json: [String: Any] = ["username": name, 
             "passwordHash": hashPass ] 

      let jsonData = try? JSONSerialization.data(withJSONObject: json) 

      let url = URL(string: LOGIN_URL)! 
      var request = URLRequest(url: url) 
      request.httpMethod = "POST" 

      // insert json data to the request 
      request.httpBody = jsonData 
      request.setValue("application/json;charest=utf-8", forHTTPHeaderField: "Content-Type") 

      print ("REQUEST : \(request)") 
      let task = URLSession.shared.dataTask(with: request) { data, response, error in 
       guard let data = data, error == nil else { 
        print(error?.localizedDescription ?? "No data") 
        return 
       } 

       if let httpResponse = response as? HTTPURLResponse { 
        print("POST : code - \(httpResponse.statusCode)") 
       } 

       let responseJSON = try? JSONSerialization.jsonObject(with: data, options: []) 
       if let responseJSON = responseJSON as? [String: Any] { 
        print(responseJSON) 
        let message:String = responseJSON["message"] as! String 
        if !(message.range(of: "ERROR") != nil){ 
         SessionMenager.Instance.token = message 
         completion(true) 
        } 
       } else{ 
        print(error.debugDescription) 

       } 
      } 
     task.resume()

Al'right！我已经弄清楚如何在好办法做到这一点在我的情况：

let stringOp = StringOperations.init() 
     let md5Data = stringOp.MD5(string:pass) 
     let hashPass = md5Data!.map { String(format: "%02hhx", $0) }.joined() 

     let json: [String: Any] = ["username": name, "passwordHash": hashPass ] 

     let jsonData = try? JSONSerialization.data(withJSONObject: json) 

     let url = URL(string: LOGIN_URL)! 
     var request = URLRequest(url: url) 
     request.httpMethod = "POST" 

     request.httpBody = jsonData 
     request.setValue("application/json;charest=utf-8", forHTTPHeaderField: "Content-Type") 

     Alamofire.request(request).responseJSON { response in 
      print("Get default graph request \(response.request!)") 
      print("Get default graph response \(response.response!)") 

      let json = JSON(response.data!) 
      let message = json["message"] 
      if !(message.stringValue.range(of: "ERROR") != nil) { 
       SessionMenager.Instance.token = message.stringValue 
       completion(true) 
      } else { 
       completion(false) 
      } 
     }

您可以使用ParameterEncoding定身编码类型。 https://github.com/Alamofire/Alamofire#parameter-encoding

Alamofire.request(LOGIN_URL, method: .post, parameters:json, encoding: JSONEncoding.default).responseJSON { ... } 

这可以用URLRequestConvertible实现以及
