Laravel:如何将INFO记录到单独的文件中

Question

如何为logging INFOin 指定单独的文件Laravel 5.1？

任何直接的帮助都将非常值得注意.谢谢

Answer 1

您是否要专门登录info到一个日志文件而将另一个日志类型登录到另一个位置？在这种情况下,我的解决方案可能无济于事,但仍然有用.

要将日志文件写入另一个位置,请使用方法useDailyFiles或useFiles,然后使用info登录到您刚指定的路径中的日志文件.像这样:

    Log::useDailyFiles(storage_path().'/logs/name-of-log.log');
    Log::info([info to log]);

两个方法的第一个参数是日志文件的路径(如果它尚不存在则创建),useDailyFiles第二个参数是Laravel在擦除旧日志之前将记录的天数.默认值是无限制的,所以在我的示例中我没有输入值.

在Laravel 5.6中,您可以创建自己的频道config\logging.php.如果您已从较旧的Laravel版本升级,则需要创建此文件(https://laravel.com/docs/5.6/upgrade).

将其添加到您的通道数组中 config\logging.php

'your_channel_name' => [
            'driver' => 'single',
            'path' => storage_path('logs/your_file_name.log'),
        ],

然后,您可以调用以下8个日志记录级别中的任何一个:

Illuminate\Support\Facades\Log::channel('your_channel_name')->info('your_message');

日志将存储在 logs/your_file_name.log

如果要添加另一个monolog处理程序,可以使用应用程序的configureMonologUsing方法.

在返回$ app变量之前,在bootstrap/app.php文件中调用此方法:

$app->configureMonologUsing(function($monolog) {
    $monolog->pushHandler(new StreamHandler('path/to/info.log', Logger::INFO, false)); // false value as third argument to disable bubbling up the stack
});

return $app;

一个简单的记录器助手,允许您即时记录多个自定义文件.您还可以添加自定义处理程序并设置文件路径.

软件\供应商\ LogToChannelsServiceProvider.php

<?php
/**
 * Logger service provider to be abled to log in different files
 *
 * @package    App\Providers
 * @author     Romain Laneuville <romain.laneuville@hotmail.fr>
 */

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Helpers\LogToChannels;

/**
 * Class LogToChannelsServiceProvider
 *
 * @package App\Providers
 */
class LogToChannelsServiceProvider extends ServiceProvider
{
    /**
     * Initialize the logger
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton('App\Helpers\LogToChannels', function () {
            return new LogToChannels();
        });
    }
}

config\app.php(添加服务提供者)

// Register Service Providers
$app->register(App\Providers\LogToChannelsServiceProvider::class);

然后,您可以使用依赖注入调用应用程序中的任何位置(在构造函数中添加类并将其绑定到log类属性)

$this->log->info('logger_name', 'Log message');
$this->log->error('other_logger_name', 'Log message', $someContext);

您甚至可以通过调用自定义记录器输出

$this->log->addChannel('channel_name', $customHandler);

当您在应用中的任何位置调用其名称时,它将可访问.

Answer 5

由于Laravel> = 5.6，我们可以使用对数通道使它以简单的方式工作。这使您可以创建日志通道，这些通道可以作为具有自己的驱动程序，路径或级别的自己的日志文件来处理。您只需要这几行就可以使其工作。

只需添加一个新频道（选择您的频道名称，例如“命令”）

config / logging.php：

return [
    'channels' => [ 
        'command' => [
            'driver' => 'single',
            'path' => storage_path('logs/command.log'),
            'level' => 'debug',
        ],
    ],
];

通过解析通道名称记录所需的位置：

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