This article mainly introduces "what is the corresponding meaning of the status code of HTTP server error". In the daily operation, I believe that many people have doubts about what the corresponding meaning of the status code of HTTP server error is. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "what is the corresponding meaning of the status code of HTTP server error?" Next, please follow the editor to study!

400illegal request (Bad Request)

If the syntax of the request is incorrect, the server will not understand. The client should not repeat the request to the server before making changes to the request.

401 unauthorized (Unauthorized)

The request requires user authorization. The WWW-Authenticate header field in the response (Section 10.16) should prompt the user to request resources in an authorized manner. The client should repeat the request with the appropriate authorization title domain (Section 10.2). If authorization trust information is already included in the request, the 401 of the response indicates that the authorization has been denied. If the user agent returns the 401 status code after many attempts, the user should take a look at the entity of the response, because some relevant dynamic information is included in the entity. HTTP access authorization is explained in section 11.

Forbidden (Forbidden)

The server understands the request but refuses to implement it. Authorization does not help, and the client should stop sending this request repeatedly. If the HEAD request method is not used, and the server is willing to disclose the reason why the request was not implemented, the server will write the rejection reason in the response entity. This status code is generally used when the server does not want to publish the details of the request being rejected or there is no other response available.

404 not found (Not Found)

The server did not find a resource that matches the request URI. The 404 status code does not indicate whether the situation is temporary or permanent. If the server does not want to provide this information to the client, it also responds to the 403 (forbidden) status code.

Server error (Server Error) 5xx: the response code with a status code starting with'5' indicates that the server has found an error and cannot continue to execute the request. If the client receives the 5xx status code and the request has not been completed, it should immediately stop sending data to the server. In addition to responding to HEAD requests, the server should include an explanation of the error condition in its response entity and indicate whether it is temporary or permanent.

This kind of response code has no title field and can be applied to any request method.

At this point, the study of "what is the corresponding meaning of the status code of the HTTP server error" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
