无法从Alamofire 3.3.0获取服务器错误消息 [英] Could not get the server error message from Alamofire 3.3.0

问题描述

这是我第一次使用 Alamofire ，这让我非常沮丧。

It is my first time for me to use Alamofire, and it got me really frustrated.

I使用以下代码在后端API上调用注册API

I'm using the following code to call a signup API on the backend API

Alamofire.request(.POST, "\(self.authBaseURL)/signup", parameters: params, headers: headers, encoding: .JSON)
            .validate(statusCode: 200..<300)
            .validate(contentType: ["application/json"])
            .responseJSON { response in
                switch response.result {
                case .Success(let JSON):
                    print("Success with JSON: \(JSON)")
                    success(updatedUser)
                case .Failure(let error):
                    print("Request failed with error: \(error)")
                    failure(error)
                }

        }

问题是错误对象我进入 .Failur e 函数不包含服务器端消息。
我试图访问其余的对象（请求，响应，数据，结果）我无法在任何地方找到我的错误消息

The problem is that the error object I'm getting in the .Failure function doesn't contain the server side message. I have tried to access the rest of the objects (request, response, data, result) I could not find my error message anywhere

我总是无论服务器消息说什么，都会收到以下错误。
请求失败并显示错误：

I'm always getting the following error, no matter what the server message has to say. Request failed with error:

FAILURE：Error Domain = com.alamofire.error Code = -6003响应状态
代码是不可接受的：400
UserInfo = {NSLocalizedFailureReason =响应状态代码是
不可接受：400}

FAILURE: Error Domain=com.alamofire.error Code=-6003 "Response status code was unacceptable: 400" UserInfo={NSLocalizedFailureReason=Response status code was unacceptable: 400}

我有什么问题吗？

Swift 2.2，AlamoFire 3.3.0，Xcode 7.3

Swift 2.2, AlamoFire 3.3.0, Xcode 7.3

推荐答案

我设法让它按照我想要的方式工作，方法是删除状态验证并手动检查statusCode

I managed to get it to work exactly the way I want is by dropping the status validation and check for the statusCode manually

Alamofire.request(.POST, "\(self.authBaseURL)/signup", parameters: params, headers: headers, encoding: .JSON)
            .validate(contentType: ["application/json"])
            .responseJSON { response in
                if response.response?.statusCode == 200 {
                    print("Success with JSON: \(response.result.value)")

                    success(updatedUser)
                }
                else {
                    let error = response.result.value as! NSDictionary
                    let errorMessage = error.objectForKey("message") as! String
                    print(errorMessage)
                    failure(errorMessage)
                }


        }
