What is the purpose of the HTTP status code? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The use of HTTP status code is to use the Web Server server to tell the client what happened to the current web request, or the response status of the current Web server, so the HTTP status code is often used to judge and analyze the current Web server.

The usefulness of HTTP status codes:

The core function of the http status code is that the Web Server server is used to tell the client what happened to the current web request, or the current response status of the Web server. Therefore, the HTTP status code is often used to judge and analyze the current Web server status.

As programmers, we need to know more about these status codes as much as possible, figure out these status codes one by one, and when we encounter them in our work, we will be able to understand where the problem is and solve the problem pertinently.

Commonly used http status codes:

The 200 OK server successfully processed the request (this is the most we have seen)

The URL for the 301ax 302 Moved Permanently (redirect) request has been removed. The Response should contain a Location URL indicating where the resource is now located

404 Not Found (page missing) resource not found

The 501 Internal Server Error server encountered an error that prevented it from serving the request

A summary of common HTTP status codes:

1, the beginning of 1: (accepted, need to continue processing. )

This type of status code indicates that the request has been accepted and needs to be processed. This type of response is temporary, contains only the status line and some optional response header information, and ends with a blank line.

2, 2 at the beginning (request successful)

This type of status code indicates that the request has been successfully received, understood, and accepted by the server

3, the beginning of 3 (request is redirected)

This type of status code means that further action by the client is required to complete the request. Typically, these status codes are used for redirection, and the subsequent request address (redirect destination) is indicated in the Location domain of this response.

4. 4 beginning: (request error)

This type of status code means that the client appears to have made an error, interfering with the server's processing. Unless you are responding to an HEAD request, the server should return an entity that explains the current error condition and whether it is temporary or permanent. These status codes apply to any request method. The browser should display to the user any entity content contained in such an error response.

5, 5 beginning: (server error)

This kind of status code represents that the server has an error or abnormal state in the process of processing the request, or it may be that the server realizes that the request cannot be processed with the current hardware and software resources. Unless this is an HEAD request, the server should contain an explanatory information entity that explains the current error state and whether the condition is temporary or permanent. The browser should show the user any entities that are included in the current response.
