Symfony

Question

我正在尝试将多个独白处理程序注入服务。现在我的 parent class 注入了一个记录器， children class 注入了另一个记录器。我的目标是能够将特定操作记录到特定日志文件中。

我的service.yaml:

App\Services\PrinterManager:
    arguments: ['@doctrine.orm.entity_manager','@logger', '', '', '', '','']
    tags:
        - { name: monolog.logger, channel: printerface}

App\Services\Printer\Printer:
    autowire: true
    autoconfigure: false
    public: false
    parent: App\Services\PrinterManager
    arguments:
        index_2: '@logger'
        index_3: '@oneup_flysystem.printer_invoice_filesystem'
        index_4: '@oneup_flysystem.printerface_content_filesystem'
        index_5: '@oneup_flysystem.sftp_filesystem'
        index_6: '@App\Services\PrinterApiService'
    tags:
        - { name: monolog.logger, channel: printerlog}

我的monolog.yaml:

monolog:
  handlers:
    main:
        type: stream
        path: "%kernel.logs_dir%/%kernel.environment%.log"
        level: debug
        channels: ["!event, !printerface", "!printerlog"]
    printerface:
        type: stream
        level: debug
        channels: ["printerface"]
        path: "%kernel.logs_dir%/printerface.log"
    printerlog:
        type: stream
        level: debug
        channels: ["printerlog"]
        path: "%kernel.logs_dir%/printerlog.log"

但似乎当前的服务配置破坏了构造函数，我得到以下错误：

The argument must be an existing index or the name of a constructor's parameter.

有没有办法在一个服务中使用两个日志文件？

这是 Symfony 用于替换子服务中父参数的方法：

/**
 * You should always use this method when overwriting existing arguments
 * of the parent definition.
 *
 * If you directly call setArguments() keep in mind that you must follow
 * certain conventions when you want to overwrite the arguments of the
 * parent definition, otherwise your arguments will only be appended.
 *
 * @param int|string $index
 * @param mixed      $value
 *
 * @return self the current instance
 *
 * @throws InvalidArgumentException when $index isn't an integer
 */
public function replaceArgument($index, $value)
{
    if (\is_int($index)) {
        $this->arguments['index_'.$index] = $value;
    } elseif (0 === strpos($index, '$')) {
        $this->arguments[$index] = $value;
    } else {
        throw new InvalidArgumentException('The argument must be an existing index or the name of a constructor\'s parameter.');
    }
    return $this;
}

如您所见，索引必须与父构造函数中的参数变量名称相同，并带有前缀 $ 或表示相关参数的整数。

所以我认为你必须如下定义你的子服务：

App\Services\Printer\Printer:
    autowire: true
    autoconfigure: false
    public: false
    parent: App\Services\PrinterManager
    arguments:
        2: '@logger'
        3: '@oneup_flysystem.printer_invoice_filesystem'
        4: '@oneup_flysystem.printerface_content_filesystem'
        5: '@oneup_flysystem.sftp_filesystem'
        6: '@App\Services\PrinterApiService'
    tags:
        - { name: monolog.logger, channel: printerlog}

更新：

我复现了你的问题，发现解决方法如下。使用此解决方案，Symfony 自动装配将适用于子服务。

App\Services\Printer\Printer:
    autowire: true
    autoconfigure: false
    public: false
    parent: App\Services\PrinterManager
    arguments:
        $arg2: '@logger'
        $arg3: '@oneup_flysystem.printer_invoice_filesystem'
        $arg4: '@oneup_flysystem.printerface_content_filesystem'
        $arg5: '@oneup_flysystem.sftp_filesystem'
        $arg6: '@App\Services\PrinterApiService'
    tags:
        - { name: monolog.logger, channel: printerlog}

$arg2、$arg3、$arg4、$arg5 和 $arg6 必须替换为 class 构造函数的参数名称。

我还没有用 parent/child class 完成它，但是我使用的是一些更简单的命名参数，这就是我所拥有的（使用三个不同的记录器）：

# App/Subscribers/WebhookLoggingListener.php file
public function __construct(
    LoggerInterface $logger, 
    LoggerInterface $mailgunLog, 
    LoggerInterface $dripLog) {
}

# services.yml
App\Subscribers\WebhookLoggingListener:
    arguments:
        $logger: "@logger"
        $mailgunLog: "@monolog.logger.mailgun"
        $dripLog: "@monolog.logger.drip"
    tags:
       - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }

如果我在别处使用其他记录器，我也可以将它们绑定到特定的变量名：

services:
    _defaults:
        # ... other config
        bind:
            $dripLog: "@?monolog.logger.drip"
