TheoreticallydebugWhen it is off, the online environment will automatically arrive404.

Do you want to "go to Page 404" or "show page 404 」? To Redirect, configure app/Exceptions/handler. php and return a Redirect response when NotFoundException is thrown.

1. if you only want to throw a 404 error, the debug switch can satisfy you. 2. if you want to handle exceptions or custom exceptions, refer to the following;

In the root directory of the laravel projectappUnderExceptionsDirectoryHandler.phpFile; here we canCustom exceptionAndException handling;

The most common one isModelNotFoundException

The following is a Demo:

Route:

vikin.cc/article/8

Handler file:

// Handle Http response exceptions public function render ($ request, Exception $ e) {switch ($ e) {// use the type operator instanceof to determine an Exception (instance) modelNotFoundException case ($ e instanceof ModelNotFoundException): // handle exceptions return $ this-> renderException ($ e); break; default: return parent: render ($ request, $ e) ;}// handle exceptions protected function renderException ($ e) {switch ($ e) {case ($ e instanceof ModelNotFoundException): // custom exception, here we return a 404 page return view ('errors. 404 '); break; default: // If The exception is not ModelNotFoundException, return the laravel default error page return (new SymfonyDisplayer (config ('app. debug ')-> createResponse ($ e );}}

Through the above cases, you can easily handle exceptions and give users a friendly prompt!
