我们可以在laravel 5.2中为不同目的创建自定义日志文件吗与order.log中的订单相关日志条目和payment相关的内容类似，该条目应登录payments.log

我想找到最好的拉维路

目前，我们只能更改日志文件频率（如每日、单个），也可以更改日志文件的名称，而不是默认名称，即laravel.log

您可以尝试重新调整日志函数的用途，将不同类型的日志写入不同的文件。这可以通过编辑

bootstrap/app.php

文件来完成：

$app->configureMonologUsing(function($monolog) {
    $bubble = false;
    $infoStreamHandler = new Monolog\Handler\StreamHandler( storage_path("/logs/orders.log"), Monolog\Logger::INFO, $bubble);
    $monolog->pushHandler($infoStreamHandler);

    $warningStreamHandler = new Monolog\Handler\StreamHandler( storage_path("/logs/logins.log"), Monolog\Logger::WARNING, $bubble);
    $monolog->pushHandler($warningStreamHandler);
});

然后在代码中，您可以执行以下操作：

Log::info('Order was created', ['ORDER-123']);

Log::warning('User login', ['USER-1']);

您可以使用此方法编辑所有可用的日志函数：

调试
信息
通知
警告
错误
关键的
警觉的
紧急情况

Log:：write（'audit'，'用户登录到应用程序'）

Log:：info（'事件'，'用户发送了2封电子邮件'）
解决方案：

                $record['level'] >= $this->level
            );
        }
    }

}

对我来说，在Laravel5.3中，我不确定它是否是我以前安装的，但我发现bootstrap/app.php不适合我
我需要把它放在app/Providers/AppServiceProvider.php中
n、 这是我之前在config中设置日志级别的地方，因此我最终使用了3个日志处理程序
public function register()
{
   $monolog = Log::getMonolog();
   foreach ($monolog->getHandlers() as $handler) {
      $handler->setLevel(Config::get('app.log_level'));
   }

   $bubble = false;
   $infoStreamHandler = new \Monolog\Handler\StreamHandler( storage_path("logs/info.log"), \Monolog\Logger::INFO, $bubble);
   $monolog->pushHandler($infoStreamHandler);

   $warningStreamHandler = new \Monolog\Handler\StreamHandler( storage_path("logs/warning.log"), \Monolog\Logger::WARNING, $bubble);
   $monolog->pushHandler($warningStreamHandler);

}

要扩展ShQ的答案：
我注意到的一个问题是日志将附加[]]
，这是LineFormatter.format（）中$context
和$extra
的空数组值
例如，vendor/monolog/monolog/src/monolog/Formatter/LineFormatter.php

有两种方法可以解决此问题，一种是为LineFormatter
的构造函数提供不包含额外或上下文的格式，另一种是提供第四个参数$ignoreEmptyContextAndExtra
=true

ShQ答案中的所有文件保持不变，但必须更改ChannelStreamHandler

ChannelStreamHandler:
<?php

namespace App\Helpers;

use Monolog\Formatter\LineFormatter;
use Monolog\Handler\StreamHandler;
use Monolog\Logger;

/**
 * Use channels to log into separate files
 *
 */
class ChannelStreamHandler extends StreamHandler
{
    /**
     * Channel name
     *
     * @var String
     */
    protected $channel;

    /**
     * @param String $channel Channel name to write
     * @param bool|int $stream
     * @param bool|int $level
     * @param bool $bubble
     * @param null $filePermission
     * @param bool $useLocking
     * @see parent __construct for params
     */
    public function __construct(
        $channel,
        $stream,
        $level = Logger::DEBUG,
        $bubble = true,
        $filePermission = null,
        $useLocking = false
    ) {
        $this->channel = $channel;

        $formatter = new LineFormatter(null, null, false, true);
        $this->setFormatter($formatter);

        parent::__construct($stream, $level, $bubble);
    }

    /**
     * When to handle the log record.
     *
     * @param array $record
     * @return bool
     */
    public function isHandling(array $record)
    {
        //Handle if Level high enough to be handled (default mechanism)
        //AND CHANNELS MATCHING!
        if (isset($record['channel'])) {
            return ($record['level'] >= $this->level && $record['channel'] == $this->channel);
        } else {
            return ($record['level'] >= $this->level);
        }
    }

}

您还必须确保运行monolog 1.22，因为它包含了一个关于ignoreEmptyContextAndExtra
的错误修复
我还向channelwriter
类添加了对info（）的覆盖：
public function info($channel, $message, array $context = [])
{
    $level = array_flip($this->levels)[$this->channels[$channel]['level']];
    $this->writeLog($channel, $level, $message, $context);
}

此外，我对ShQ解决方案中的“惰性负载记录器”不满意，因为它被修改为使用服务提供商/IoC
替换ChannelWriter.writeLog（）
：
在您的AppServiceProvider
中：
    $this->app->bind('eventlog', function () {
        return new Logger('event');
    });

    $this->app->bind('auditlog', function () {
        return new Logger('audit');
    });

我将尝试将其打包成一个包。
有一个简单的方法：
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = ['orderId' => 10,
        'description' => 'Some description'];

//first parameter passed to Monolog\Logger sets the logging channel name
$orderLog = new Logger('order');
$orderLog->pushHandler(new StreamHandler(storage_path('logs/order.log')), Logger::INFO);
$orderLog->info('OrderLog', $log);

日志/order.log中的输出：
[2017-04-30 00:00:00] order.INFO: OrderLog {"orderId":10, "description":"Some description"} []

基于ShQ答案，这是一个更短、更简单的记录器帮助程序，允许您动态地登录到自定义文件。您还可以添加自定义处理程序并设置文件路径

config\app.php（添加到别名）
然后你可以在应用程序中的任何地方调用
Log::info('logger_name', 'Log message');
Log::error('other_logger_name', 'Log message', $someContext);

您甚至可以通过调用
Log::addChannel('channel_name', $customHandler);

当您在应用程序中的任何位置调用它的名称时，它都可以访问。
将日志输出到不同文件的最快方式
Log::useFiles('path/to/file.log');
Log::info('Info');

现在以更简单的方式支持这一点
创建一个频道
转到：root/config/logging.php
，在channels
数组下添加自定义频道，即

“付款”=>[
“驱动程序”=>“单个”，
'path'=>存储路径（'logs/payments.log'），
“级别”=>“信息”，
],

在路由或控制器中写入此日志
Log:：channel（'payments'）->info（'A transaction haved！'）；

付款日志可在/storage/logs/payments.log
注意：可扩展以进一步增强您的需求
Laravel 5.6版
我管理了自己的日志函数，它可以放在app dir的helper.php文件中
if ( ! function_exists( 'write_log' ) ) {
    /**
     * Write log to log file
     *
     * @param string|array|object $log
     */
    function write_log( $log ) {
        if ( env('APP_LOG_LEVEL', 'debug') == 'debug' ) {
            if ( is_array( $log ) || is_object( $log ) ) {
                file_put_contents(laravelInstallDir().'../debug.log', print_r( $log, true ), FILE_APPEND);
            } else {
                file_put_contents(laravelInstallDir().'../debug.log', $log, FILE_APPEND);
            }
        }
    }
}

请根据需要调整路径laravelInstallDir（）。../debug.log这是在Laracast上发布的一条注释，用于相同的问题：是否可以在记录消息之前使用log:：useFiles（）
并指定文件名？如果是这样的话，Laravel来谈谈吧。按错误级别对单独的日志进行处理非常好，谢谢。我们可以使用env（）在外部设置日志路径而不是使用此存储路径（“/logs/orders.log”），是的，您可以将存储路径（“/logs/orders.log”）
行更改为env（“/logs/orders.log”）
，因此，如果没有定义env，日志可以返回到存储路径。我已经对这个答案进行了更新，但如果它链接到文档，则会更有帮助：另外，通过将这些行添加到u构造方法：$this->channels['event']['path']='logs/audit-'中，可以拥有每日日志文件。日期（“Y-m-d”）。对数'$此->通道['audit']['path']='logs/audit-'。日期（“Y-m-d”）。对数'；这段代码在日志消息中创建了额外的[]，有什么想法吗？@codebob请参阅下面我关于[]]
问题的答案。这是因为它使用默认的LineFormatter.php实例和默认的格式化程序。我有同样的[][]问题，我如何删除它们？请注意。它不会删除log_max_文件中指定的旧文件。这是一种添加额外日志记录的非常简洁和简单的方法，只是一个问题，这会继续向单个日志文件或wi添加条目吗

Log::useFiles('path/to/file.log');
Log::info('Info');

Solution:

step1: create a channel inside config/logging.php file

example :

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

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

]

Step2: Now set dynamic path from the controller  like this

config(['logging.channels.web.path' => storage_path('logs/web/'.time().'.log')]);

Step3 : now generate your log

  Log::channel('web')->info("your message goes here");

Enjoy :)
