推荐答案

HTTP状态代码是服务器的响应，因此，如果您控制服务器，则可以使其返回所需的任何错误.如果您无法控制服务器，则可以尝试发送错误/无效请求，以便服务器发出投诉.

HTTP Status Codes are responses from the server, therefore if you have control of the server then you could make it return whichever errors you want. If you don't have control of the server then you could try sending bad/invalid requests so that the server will complain.

在服务器端这样的事情:

Something like this on your server side:

@RequestMapping(method = RequestMethod.GET)
public ResponseEntity getAnError() {
    // complain!
    return ResponseEntity.status(HttpStatus.FORBIDDEN);
}
