【postman】post请求出现 “status“: 400, “error“: “Bad Request“

• 1、出错信息
• 2、springboot代码
• 3、解决方法

post：http://localhost:8080/stu/create

    "timestamp": "2021-12-28T09:56:13.741+00:00",
    "status": 400,
    "error": "Bad Request",
    "path": "/stu/create"

 @PostMapping("create")
    public String createStu(@RequestBody Map map,@RequestHeader("token") String token,
                             @cookievalue("clientId") String clientId, HttpServletRequest request)
    {
        log.info("map = " + map.toString());
        log.info("clientId = " + clientId);
        log.info("token = " + token);
       String header = request.getHeader("token");
        log.info("header = " + header);
        return "新增Stu";
    }

在保证代码没有出错的情况下，排查出的问题是cookie，在postman中添加cookie时，发现名字错误，将名字改为localhost，问题解决。
