------ Solution --------------------
404 page is a web server event and has nothing to do with server scripts
------ Solution --------------------
Ngnix 404
Error_page 404 =/404.html

Add it to the conf configuration file.


In Apache 404
ErrorDocument 404/404 .html

------ Solution --------------------
You can directly use the 404 page of the web server, or you can directly write one, and then modify the configuration file.
