Spring post方法“缺少所需的请求正文" [英] Spring post method "Required request body is missing"

问题描述

@PostMapping(path="/login")
public ResponseEntity<User> loginUser(@RequestBody Map<String, String> userData) throws Exception {
    return ResponseEntity.ok(userService.login(userData));
}

我在UserController中使用此方法进行登录.问题是当我尝试发出登录请求时，出现此错误:

I have this method for the login in the UserController. The problem is when i try to make the post request for the login i get this error:

{
"timestamp": "2018-10-24T16:47:04.691+0000",
"status": 400,
"error": "Bad Request",
"message": "Required request body is missing: public org.springframework.http.ResponseEntity<org.scd.model.User> org.scd.controller.UserController.loginUser(java.util.Map<java.lang.String, java.lang.String>) throws java.lang.Exception",
"path": "/users/login"
}

推荐答案

如果是POST请求，则必须将其作为JSON传递给您.

You have to pass that as JSON in your body, if it's a POST request.
