删除404的所有例外

如果有渲染方法,请更改它,或添加该方法。

public function render($request, Exception $exception)
{
    if($exception instanceof NotFoundHttpException){
        return response()->view('errors/404', ['invalid_url'=>true], 404);
    }

    if ($exception instanceof TokenMismatchException && Auth::guest()) {
        error_log('Error :' . $exception->getMessage());
        abort(500);
    }

    if ($exception instanceof TokenMismatchException && getenv('APP_ENV') != 'local') {
        return redirect()->back()->withInput();
    }

    if($exception instanceof \Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException && getenv('APP_ENV') != 'local') {
        error_log('Error :' . $exception->getMessage());
        abort(404);
    }

    if(($exception instanceof PDOException || $exception instanceof QueryException) && getenv('APP_ENV') != 'local') {
        error_log('Error :' . $exception->getMessage());
        abort(500);
    }

    if ($exception instanceof ClientException) {
        error_log('Error :' . $exception->getMessage());
        abort(500);
    }

    return parent::render($request, $exception);
}

有优雅的方式做你想做的事。Laravel在app/exceptions目录中有一个名为handler.php的文件。此文件包含名为handler的类,并且有render方法。就这样!您应该使用此方法将所有异常转换为404异常,如下所示:

/**
 * @param $request
 * @param Exception $exception

 * @return mixed
 */
public function render($request, Exception $exception)
{
    // you could do abort(404) if you prefer helpers
    $notFoundException = new NotFoundHttpException($exception->getMessage());

    return parent::render($request, $notFoundException);
}

try{
 ... your fancy code here
}catch(Exception $e){
 abort(404, 'Custom 404 error message');
}
