Laravel is a very popular PHP framework. The error prompt mechanism it provides allows you to quickly locate the cause when problems occur during the development process, thus improving development efficiency. However, sometimes we don’t want users to see any error prompts when we officially go online. At this time, we can solve this problem by blocking the error prompts. This article will introduce how to block error prompts in Laravel.
In the Laravel framework, we can block error prompts by turning off debug mode. Open the .env
file in the project and change the value of APP_DEBUG
from true
to false
to turn off the debug mode.
Turning off debug mode will block all error prompts on the page, including 500 pages and Laravel error messages. This method is suitable for situations where all error prompts and logs need to be cleared, such as the official online environment.
It should be noted that it is not recommended to turn on debug mode in a production environment. After turning on the debug mode, various Laravel error messages will be displayed on the page. This information can help us quickly locate the problem. However, in the officially launched environment, any error message will bring an extremely bad user experience to users and will also have a serious impact on the website's brand image.
The second way to shield error prompts is to customize the exception handler. We can mask error prompts on the page by rewriting Laravel's own exception handler. The following is a simple example:
<?php namespace App\Exceptions; use Exception; class Handler extends ExceptionHandler { public function render($request, Exception $exception) { if ($this->isHttpException($exception)) { return $this->renderHttpException($exception); } else { return response()->view('errors.500'); } } }
In the above code, we define a Handler
class, which inherits Laravel's own exception handler ExceptionHandler
. In this class, we override the render
method. When we catch an exception, we will first determine whether the exception type is HttpException
. If so, renderHttpException# will be called. ##Method outputs exception information to the page. If not, a 500 error page will be returned (no error message will be displayed at this time).
render method and make different treatments according to different exception types.
