将HTTP X-Request-Id添加到Symfony日志中的实例

在这个例子中，我们将把HTTP X-Request-Id添加到Symfony日志中，这样就可以更容易地将错误与请求联系起来。

前提条件

请确保你做了这篇文章的内容。假设你也已经安装了Monolog。

XRequestIdProcessor

declare(strict_types=1);

namespace App\Logger;

class XRequestIdProcessor
{
    private $xRequestId;

    public function __construct(?string $xRequestId)
    {
        $this->xRequestId = $xRequestId;
    }

    public function __invoke(array $record)
    {
        $record['context']['x_request_id'] = $this->xRequestId;

        return $record;
    }
}

# config/services.yaml
parameters:
    env(HTTP_X_REQUEST_ID): ~

services:
    App\Logger\XRequestIdProcessor:
        arguments:
            $xRequestId: '%env(string:HTTP_X_REQUEST_ID)%'
        tags:
            - { name: monolog.processor }

结果

如果你想让你的日志转到Docker终端而不是你的应用程序的var\log 文件夹，请在monolog配置文件中使用path: "php://stderr" 。

成功
