ThinkPHP 6 – Overriding exception throwing

In ThinkPHP 6, you can achieve this through inheritance. think\Exception Class, then override render A method for implementing custom exception handling logic.

Here is a simple example code:

<?php
namespace app\exception;

use think\exception\HttpException;

class MyException extends HttpException
{
    public function render($request)
    {
        // 自定义异常处理方式
        return "发生了错误：" . $this->getMessage();
    }
}

In the above code, we have created one. MyException Class, and inherits think\exception\HttpExceptionIn this class, we have rewritten the method. render This method is invoked when an exception occurs to handle it.

In this example, we return a simple text string that will contain our custom error message.

Then, we can use it anywhere in the application where exception handling is required. throw Statement thrown MyException target:

throw new \app\exception\MyException("自定义异常信息");

This exception will be defined by us. MyException Class processing, invocation render The method returns custom exception information.
