Laravel 如何处理 PHP 警告?

2022-01-17 00:00:00 exception ldap php laravel

我正在尝试使用 Laravel 连接到 LDAP 服务器.重要的是要说我正在使用 PHP 函数 ldap_connect 和 ldap_bind 而不是使用包来处理它.

I'm trying to connect to a LDAP server using Laravel. It is important to say that I'm using the PHP functions ldap_connect and ldap_bind instead of using a package to handle it.

关键是当我提供错误的用户名和密码时，ldap_bind 函数会给我们一个 PHP 警告.我可以接受这个警告，并且正如文档中所述，当绑定没有发生时，该函数返回 false.

The point is that when I provide wrong user and password, the ldap_bind function gives to us a PHP warning. I'm OK with this warning and, as is in the documentation, the function returns false when the bind does not occur.

但是，当这个警告被触发时，Laravel 会抛出一个异常.这不是异常，Laravel 不应该抛出异常，我不想将其作为异常处理；我只需要构建一个 if 条件，它将向用户返回一条消息.

But, Laravel is throwing an exception when this warning is triggered. This is not an exception, Laravel should not throw an exception and I wouldn't like to handle this as an exception; I just have to build an if condition that will return a message to the user.

Laravel 是否将所有警告都视为异常?

Does Laravel catch all warnings as an Exception?

推荐答案

这是 Laravel 的预期行为.Laravel 会将任何错误转换为 ErrorException 实例.这是 bootstrap() 方法L42" rel="nofollow noreferrer">Illuminate/Foundation/Bootstrap/HandleExceptions.php 类.

This is the intended behavior for Laravel. Laravel will turn any error into an ErrorException instance. Here's the bootstrap() method inside the Illuminate/Foundation/Bootstrap/HandleExceptions.php class.

public function bootstrap(Application $app)
{
    $this->app = $app;

    error_reporting(-1);

    set_error_handler([$this, 'handleError']);

    set_exception_handler([$this, 'handleException']);

    register_shutdown_function([$this, 'handleShutdown']);

    if (! $app->environment('testing')) {
        ini_set('display_errors', 'Off');
    }
}

error_reporting(-1); 将设置 PHP 报告所有错误(阅读更多 这里).

The error_reporting(-1); will set PHP to report all errors (read more here).

虽然这部分代码:

set_error_handler([$this, 'handleError']);

将设置自定义错误处理程序.如果检查 handleError() 方法，很明显 Laravel 会将任何错误转换为 ErrorException 实例.

Will set a custom error handler. If you check the handleError() method, it's pretty clear that Laravel will turn any error into an ErrorException instance.

public function handleError($level, $message, $file = '', $line = 0, $context = [])
{
    if (error_reporting() & $level) {
        throw new ErrorException($message, 0, $level, $file, $line);
    }
}

希望这能把事情弄清楚.:)

Hope this clear things up. :)
