How to block error prompts in Laravel (two methods)

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.

The first way: turn off debug mode

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.

Second way: Custom exception handler

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).

It should be noted that in actual development, we may also need to handle some custom exception types. At this time, we can add corresponding judgment logic to the

render method and make different treatments according to different exception types.

Conclusion

This article explains two methods of turning off debug mode and customizing exception handlers to shield error prompts. It is necessary to choose the appropriate method according to the actual situation. Turning off debug mode can effectively block all error prompts and logs in the production environment, and is suitable for use before official launch. By customizing exception handlers, we can flexibly control different types of exceptions and handle them accordingly.
