Understanding HTTP Status Codes

HTTP status codes are standard responses given by web servers on the internet. The codes help identify the cause of the problem when a web page or API doesn't load properly.

They are grouped into five classes: 1xx (Informational), 2xx (Success), 3xx (Redirection), 4xx (Client Error), and 5xx (Server Error).

常见问题解答

A 404 Not Found error indicates that the server could not find the requested webpage or file.

401 means you are not authenticated (not logged in), while 403 means you are authenticated but do not have permission to access the resource.
