Question

在我的app.php文件中：

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

class App extends \DI\Brifge\Slim\app
{
 public function configureContainer(ContainerBuilder $builder)
 {
  $dependencies = [
            'logger' => function (Container $container) { 
            $logger = new Monolog\Logger('logger');
            $filename = _DIR__ . '/../log/error.log';
            $stream = new Monolog\Handler\StreamHandler($filename, Monolog\Logger::DEBUG);
            $fingersCrossed = new Monolog\Handler\FingersCrossedHandler(
            $stream, Monolog\Logger::ERROR);
            $logger->pushHandler($fingersCrossed);

            return $logger;
        },
      ];
    }
   }

在我的自定义错误处理程序中：

class CustomErrorHandler
{
 protected $logger;

 public function __construct(Logger $logger)
 {
    $this->logger = $logger;
 }

 public function __invoke(ServerRequestInterface $request, ResponseInterface $response, $exception)
 {
    $output = ['success'=>0, 'error'=>"Oops! Something's not right "];

    $this->logger->critical($output);

    return $response->withStatus(500)
                    ->withHeader('Content-Type', 'application/json')
                    ->write(json_encode($output));
 }
}

抛出错误时，会显示以下消息：

我在App.php文件中包含了use Monolog\Logger;语句，但是我收到了上述错误。

您忘记在configureContainer方法中注册依赖项：

使用Monolog \ Logger; 使用Monolog \ Handler \ StreamHandler;

class App extends \DI\Bridge\Slim\App
{
    public function configureContainer(ContainerBuilder $builder)
    {
        $dependencies = [
            'logger' => function (Container $container) { 
                $logger = new Monolog\Logger('logger');
                $filename = _DIR__ . '/../log/error.log';
                $stream = new Monolog\Handler\StreamHandler($filename, Monolog\Logger::DEBUG);
                $fingersCrossed = new Monolog\Handler\FingersCrossedHandler(
                $stream, Monolog\Logger::ERROR);
                $logger->pushHandler($fingersCrossed);

                return $logger;
            },
        ];

        // Register definitions
        $builder->addDefinitions($dependencies);
    }
}

您在App班级声明中也有错，它是\DI\Bridge\Slim\App，而不是\DI\Brifge\Slim\app

Answer 2

我明白我错了。不需要包括这些行：

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

在实例化时，我已经包含了完整的路径。

如何在苗条3中使用monolog？
