基于x-www-form-urlencoded与Spring @Controller的问题的答案

我写了下面的@Controller方法

@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST
            , produces = {"application/json", "application/xml"}
            ,  consumes = {"application/x-www-form-urlencoded"}
    )
     public
        @ResponseBody
        Representation authenticate(@PathVariable("email") String anEmailAddress,
                                    @RequestBody MultiValueMap paramMap)
                throws Exception {


            if(paramMap == null || paramMap.get("password") == null) {
                throw new IllegalArgumentException("Password not provided");
            }
    }

请求失败并出现以下错误

{
  "timestamp": 1447911866786,
  "status": 415,
  "error": "Unsupported Media Type",
  "exception": "org.springframework.web.HttpMediaTypeNotSupportedException",
  "message": "Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported",
  "path": "/users/usermail%40gmail.com/authenticate"
}

这是我第一次使用Alamofire它,它让我非常沮丧.

我正在使用以下代码在后端API上调用注册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)
                }

        }

问题是我在.Failure函数中获得的错误对象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

无论服务器消息说什么,我总是会收到以下错误.请求失败并显示错误:

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

我在做什么有什么不对吗？

Swift 2.2,AlamoFire 3.3.0,Xcode 7.3

有没有办法304 Not Modified用 Alamofire 4检测响应？我发现response.statusCode即使服务器以 304 响应，Alamofire也始终为 200。

网络通话设置：

Alamofire 
    .request("http://domain.com/api/path", method: .get)
    .validate(statusCode: 200..<300)
    .validate(contentType: ["application/json"])
    .responseJSON { response in 
        print(response.response?.statusCode)
}

Alamofire 响应头

<NSHTTPURLResponse: 0x61800003e1c0> { URL: http://domain.com/api/path } { status code: 200, headers {
    "Access-Control-Allow-Headers" = "content-type, authorization";
    "Access-Control-Allow-Methods" = "GET, PUT, POST, DELETE, HEAD, OPTIONS";
    "Access-Control-Allow-Origin" = "*";
    "Cache-Control" = "private, must-revalidate";
    Connection = "keep-alive";
    "Content-Type" = "application/json";
    Date = "Mon, 23 Jan 2017 23:35:00 GMT";
    Etag = "\"f641...cbb6\"";
    "Proxy-Connection" = "Keep-alive"; …
