@RequestBody MultiValueMap不支持内容类型'application/x-www-form-urlencoded; charset = UTF-8' [英] Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported for @RequestBody MultiValueMap

问题描述

基于答案 x-www-form-用Spring @Controller urlencode

我写了下面的@Controller方法

I have written the below @Controller method

@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");
            }
    }

失败并显示以下错误的请求

the request to which fails with the below error

{
  "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"
}

[PS:泽西岛要友好得多，但鉴于这里的实际限制，现在无法使用它]

[PS: Jersey was far more friendly, but couldn't use it now given the practical restrictions here]

推荐答案

问题是，当我们使用 application/x-www-form-urlencoded 时，Spring不会将其理解为RequestBody .所以，如果我们要使用这个 我们必须删除 @RequestBody 注释.

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

然后尝试以下操作:

@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST,
        consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE, 
        produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody  Representation authenticate(@PathVariable("email") String anEmailAddress, MultiValueMap paramMap) throws Exception {
   if(paramMap == null && paramMap.get("password") == null) {
        throw new IllegalArgumentException("Password not provided");
    }
    return null;
}

请注意，已删除注释 @RequestBody
