即使设置为 Slim 仍会处理错误

Question

这是我的主要 Slim 应用程序实例化代码：

$slimSettings = [
    'settings' => [
        'displayErrorDetails' => false,
        'routerCacheFile'     => false  # Settings::ABSPATH . '/tmp/route.cache'
    ],
];

# Initialize
$app = new \Slim\App( $slimSettings );

# Create container
$container = $app->getContainer();

# Register component on container
$container[ 'view' ] = function( $container ) {
    $renderer = new \Slim\Views\PhpRenderer();
    $renderer->setAttributes( [ 'absPath' => Settings::ABSPATH ] ); # Variable accessible from all templates

    return $renderer;
};

# Remove error handling from slim, so custom error handling is used.
unset( $app->getContainer()[ 'errorHandler' ] );

您可以看到最后一行应该取消设置 errorHandler。然而，例如在控制器中我声明了一个函数：

public function index( $request, Response $response )

我忘记设置 'Response' use 语句，所以它产生了一个错误（很容易修复，但这不是重点）。但是这个错误被 slim 处理了。这是为什么？难道不应该不处理 unset 语句的错误吗？

更新：错误：

Answer 1

从您发布的错误输出来看，Slim 似乎没有处理错误，而是使用了默认的 php 错误处理程序。

Slim 错误输出看起来像这样：

Answer 2

Argument 2 passed to Rib\Src\Controllers\HomeController::index() must be an instance of Rib\Src\Controllers\Response, instance of Slim\Http\Response given

这是一个命名空间声明error.Answer

在您的控制器文件 (HomeController) 顶部添加：

use \Psr\Http\Message\ResponseInterface as Response;

更新

抱歉，我看错了问题。所以，你想知道为什么这个错误被 Slim 处理了。

这是因为错误是 PHP 运行时错误。 Slim 对此有特殊的处理程序。在容器中，它存储在 phpErrorHandler 键下。默认情况下，它 returns 一个 500 响应代码，当然，您可以定义自己的错误处理程序。

因此，要禁用 Slim 对 PHP 错误的处理，请取消设置 $container['phpErrorHandler']。

重要说明： 此处理程序仅 PHP7+，因为 PHP Error class was introduced in PHP7.0.

您可以阅读有关主题 here 的更多信息。

即使设置为 Slim 仍会处理错误
