【springboot】springboot接收不同的Content-Type类型请求

1. Content-Type:application/json

application/json:是以json字符串的格式请求

springboot中 application/json:只能以@requestBody注解接收对象

Postman请求示例：

后台示例：

@PostMapping(value = "/asset", produces = Constants.APPLICATION_JSON_UTF)
    public AssertResultEntity Assets(@RequestBody AssertEntity assertEntity) {

        // 获取邮箱前缀
        String userName = assertEntity.getMailPrefix();
        AssertItemEntity asset = assetService.getAssetByName(userName);

        return AssertResultEntity.success(asset);
    }

2. Content-Type:application/x-www-form-urlencoded

application/x-www-form-urlencoded:浏览器默认请求，数据是jquery的Ajax请求的默认方式，这种方式的好处是浏览器都支持，在请求过程中会对数据进行序列化，以键值对的形式k1=v1&k2=v2

springboot 可以通过@requestParam()注解接收

后台示例：

 @PostMapping(value = "/asset-change", produces = Constants.APPLICATION_WWW_FORM_URL_ENCODED)
    public AssertResultEntity AssetsChange(@RequestParam(value = "asset_type") String assetType,
                                           @RequestParam(value = "rid_list") List ridList,
                                           @RequestParam(value = "attr_name") String attrName,
                                           @RequestParam(value = "origin_user") String originUser,
                                           @RequestParam(value = "new_user") String newUser,
                                           @RequestParam(value = "operator") String operator,
                                           @RequestParam(value = "sign") String sign
                                           ) {

        System.out.println(originUser);
        return AssertResultEntity.success();
    }

总结：

前端请求传Json对象则后端使用@RequestParam；
前端请求传Json对象的字符串则后端使用@RequestBody。
