laravel 每次触发 Log::error 时发送一个 slack 通知

Send a slack notification every time Log::error is triggered

提问by rap-2-h

Using Laravel 5, I want to be notified (on slack but it does not matter) every time Log::error(or similar) is triggered, by a direct call to this method or by the default ExceptionHandlercalling reportmethod. I think I have to extends default Laravel's Log system but I'm not sure. What's the (best) "laravel way" to do this ?(without changing every Log::errorcalls in my whole code).

使用 Laravel 5，我希望在每次Log::error（或类似）被触发时（通过直接调用此方法或通过默认ExceptionHandler调用report方法）得到通知（在 slack 上但无所谓）。我想我必须扩展默认的 Laravel 日志系统，但我不确定。执行此操作的（最佳）“laravel 方式”是什么？（无需更改Log::error我整个代码中的每个调用）。

First, I thought I only have to change Log Facade to one other but it will not handle the ExceptionHandler(i.e. on 500 errors due to uncaught Exception). One other solution could be add some code directly in the ExceptionHandler, but it will not be triggered if I report an error by Log::error()or some other way (app('logger')->error(), logger()->error(), etc.).

首先，我认为我只需要将 Log Facade 更改为另一个，但它不会处理ExceptionHandler（即由于未捕获的异常导致 500 个错误）。另一种解决方案可能是直接在添加一些代码ExceptionHandler，但如果我报告错误，否则它将不会被触发Log::error()或其他方式（app('logger')->error()，logger()->error()，等）。

The Logfacade is really just a wrapper for an underlying instance of Monolog. The good news is Monolog comes with support for Slack. You just need to tell Monolog to use it.

该Log门面实际上只是一个基本的实例的包装Monolog。好消息是 Monolog 支持 Slack。你只需要告诉 Monolog 使用它。

With that said, everything can be setup in 3 lines of code.

话虽如此，一切都可以在 3 行代码中设置。

$monolog = \Log::getMonolog();
$slackHandler = new \Monolog\Handler\SlackHandler('your-token', '#your-channel', 'Monolog', true, null, \Monolog\Logger::ERROR);
$monolog->pushHandler($slackHandler);

Then to get this running, you can either create your own service provider for it or just drop it in AppServiceProvider's bootmethod.

然后为了让它运行，你可以为它创建你自己的服务提供者，或者只是将它放入AppServiceProvider的boot方法中。

You may want to look at the source code for SlackHandlerjust in case there are more options the constructor takes which you would need to use.

您可能需要查看源代码，SlackHandler以防万一构造函数需要使用更多选项。

Now whenever you \Log::error('some error');, that error's message will be sent to the Slack channel you have setup. Please note this "bubbles up" which means it will be sent to the Slack channel for any logging done error and up, error, critical, alert, and emergency. Set the bubbleparameter to falseif you only want it to log errors.

现在，无论何时\Log::error('some error');，该错误消息都会发送到您设置的 Slack 频道。请注意这个“冒泡”，这意味着它将被发送到 Slack 通道，以获取任何日志记录完成错误和 up error、critical、alert、 和emergency。如果您只希望它记录s bubble，false请将参数设置为error。

For Laravel 5.6 and above:

对于 Laravel 5.6 及更高版本：

Laravel suppports slack driver for logging beginning with 5.6. Configure your slack channel in config/logging.phplike so:

Laravel 从 5.6 开始支持日志记录的 slack 驱动程序。config/logging.php像这样配置你的松弛通道：

'slack' => [
    'driver' => 'slack',
    'url' => env('LOG_SLACK_WEBHOOK_URL'),
    'username' => 'Laravel Log',
    'emoji' => ':boom:',
    'level' => 'critical',
],

Now all the log messages which have an importance critical or above will automatically logged to slack channel.

现在，所有具有关键或以上重要性的日志消息都将自动记录到 slack 通道。

You can also log to slack channel specifically:

您还可以专门登录到 slack 频道：

Log::channel('slack')->info('Something happened!');

You can listen to illuminate.log [String $level, String $message, Array $context]event. If $levelequals error, you will send notification.

您可以收听illuminate.log [String $level, String $message, Array $context]事件。如果$level等于error，您将发送通知。

Define event listener in your EventServiceProvider

定义事件侦听器 EventServiceProvider

protected $listen = [
    'illuminate.log' => [
        'App\Listeners\LogEventListener'
    ]
];

This will tell Laravel to fire LogEventListenerwhen illuminate.logevent is fired.

这会告诉Laravel火灾LogEventListener时，illuminate.log事件被触发。

Then create this listener:

然后创建这个监听器：

namespace App\Listeners;

use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

class LogEventListener
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  DeployDisabledEvent  $event
     * @return void
     */
    public function handle($event)
    {
        if ($event->type == 'error') {
            $this->notifyViaSlack($event->message, $event->context);
        }
    }

    /**
     * Send Slack notification.
     *
     * @param  string  $message
     * @param  string  $context
     * @return void
     */
    protected function notifyViaSlack($message, $context)
    {
        /*
         * Slack notification logic
         */
    }
}
