Laravel 4-捕获错误

Question

It seems like its not possible to catch errors yourself, insted of getting the laravel 4 error output.

For example if i try:

    $databaseConfig = Config::get('database.connections.mysql');
    $connect = mysql_connect($databaseConfig['host'], $databaseConfig['username'], $databaseConfig['password']);
    if (!$connect)
    {
        return 'error';
    }

If a error occurs i won't get the "error", insted laravel shows me the exception (on that orange site).

The same if you go ahead and try a

try {
    $pdo = DB::connection('mysql')->getPdo();
}
    catch(PDOException $exception) {
    return Response::make('Database error! ' . $exception->getCode());
}

Is there any way to do that?

Answer 1

The code you provided should work just fine. If I put this in my routes.php, I see the expected error string (without the orange).

Route::get('error', function() {
    try
    {
        $pdo = DB::connection('mysql')->getPdo();
    }
    catch(PDOException $exception)
    {
        return Response::make('Database error! ' . $exception->getCode());
    }
    return 'all fine';
});

What might be happening here, is that your PDOException isn't caught. Try added a backslash to the PDOException so you'll be sure it's the one defined in the root and not in the current namespace.

catch(\PDOException $exception)

Also, try to run the code directly from within the routes.php file and see if it behaves the same.

Take a look at this page: http://laravel.com/docs/errors

Quick example:

App::error(function(PDOException $e)
{
    Log::error($exception);

    return Response::make('Database error! ' . $exception->getCode());
});

Answer 3

App::error(function(Exception $exception) {
echo '<pre>';
echo 'MESSAGE :: ';
    print_r($exception->getMessage());
echo '<br> CODE ::';
    print_r($exception->getCode());
echo '<br> FILE NAME ::';
    print_r($exception->getFile());
echo '<br> LINE NUMBER ::';
    print_r($exception->getLine());
die();// if you want than only
});

put this code in your route file...

all most errors will be covered.

I know my answer is very late. But after referencing from above answers, I hadn't solved the problem.

After looking at this site (very clear explanation here): https://stackify.com/php-try-catch-php-exception-tutorial/

Here is an additional answer:

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
