laravel 5.2 不同任务的自定义日志文件

Question

我们可以在 laravel 5.2 中创建用于不同目的的自定义日志文件，例如应该在 order.log 中的订单相关日志条目以及应该在 Payments.log 中记录付款相关内容的条目

我想找到最好的 Laravel 方式。

目前我们只能更改日志文件频率（例如每天、单个）或者我们可以更改默认日志文件的名称，即 laravel.log

Answer 1

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"} []

Answer 2

给你...我花了很多时间向 Monolog 添加自定义功能，它能够以适当的方式做到这一点。 我尝试了很多不同的方法，但都有点hacky。 最后我找到了一个让这个功能正常工作的好方法......

由于应用比较大，我需要单独的日志文件，并尽可能维护现有的 Laravel 的 Log 接口。 我需要这样的东西：

Log::write('audit', 'User logged in to the app.');
Log::info('event', 'User sent out 2 emails.');

解决方案：

App\\Providers\\AppServiceProvider.php（添加注册功能）

//Facade to Object binding
$this->app->bind('chanellog', 'App\Helpers\ChannelWriter');

config\\app.php（添加到别名）

//Custom Alias Class
'ChannelLog' => App\Contracts\Facades\ChannelLog::class,

App\\Contracts\\Facades\\ChannelLog.php

<?php

namespace App\Contracts\Facades;

use Illuminate\Support\Facades\Facade;

/**
 * @see \Illuminate\Log\Writer
 */
class ChannelLog extends Facade
{
    /**
     * Get the registered name of the component.
     *
     * @return string
     */
    protected static function getFacadeAccessor()
    {
        return 'chanellog';
    }
}

App\\Helpers\\ChannelWriter.php

<?php

namespace App\Helpers;

use Monolog\Logger;

use App\Helpers\ChannelStreamHandler;

class ChannelWriter
{
    /**
     * The Log channels.
     *
     * @var array
     */
    protected $channels = [
        'event' => [ 
            'path' => 'logs/audit.log', 
            'level' => Logger::INFO 
        ],
        'audit' => [ 
            'path' => 'logs/audit.log', 
            'level' => Logger::INFO 
        ]
    ];

    /**
     * The Log levels.
     *
     * @var array
     */
    protected $levels = [
        'debug'     => Logger::DEBUG,
        'info'      => Logger::INFO,
        'notice'    => Logger::NOTICE,
        'warning'   => Logger::WARNING,
        'error'     => Logger::ERROR,
        'critical'  => Logger::CRITICAL,
        'alert'     => Logger::ALERT,
        'emergency' => Logger::EMERGENCY,
    ];

    public function __construct() {}

    /**

     * 
     * @param type $channel
     * @param type $message
     * @param array $context
     * @throws InvalidArgumentException
     */
    public function writeLog($channel, $level, $message, array $context = [])
    {
        //check channel exist
        if( !in_array($channel, array_keys($this->channels)) ){
            throw new InvalidArgumentException('Invalid channel used.');
        }

        //lazy load logger
        if( !isset($this->channels[$channel]['_instance']) ){
            //create instance
            $this->channels[$channel]['_instance'] = new Logger($channel);
            //add custom handler
            $this->channels[$channel]['_instance']->pushHandler( 
                new ChannelStreamHandler( 
                    $channel, 
                    storage_path() .'/'. $this->channels[$channel]['path'], 
                    $this->channels[$channel]['level']
                )
            );
        }

        //write out record
        $this->channels[$channel]['_instance']->{$level}($message, $context);
    }

    public function write($channel, $message, array $context = []){
        //get method name for the associated level
        $level = array_flip( $this->levels )[$this->channels[$channel]['level']];
        //write to log
        $this->writeLog($channel, $level, $message, $context);
    }

    //alert('event','Message');
    function __call($func, $params){
        if(in_array($func, array_keys($this->levels))){
            return $this->writeLog($params[0], $func, $params[1]);
        }
    }

}

App\\Helpers\\ChannelStreamHandler.php

<?php

namespace App\Helpers;

use Monolog\Handler\StreamHandler;

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

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

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

    /**
     * When to handle the log record. 
     * 
     * @param array $record
     * @return type
     */
    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
            );
        }
    }

}

在此之后，您可以在任何文件中执行以下操作：

use ChannelLog as Log;
...
function myFunction(){
    //Recommended (writes INFO to logs/event.log)
    Log::write('event', 'User sent out 3 voucher.')
    //Possible to use (writes ALERT to logs/audit.log)
    Log::alert('audit', 'User modified xyz entry.')
    //Or even: 
    Log::write('audit', 'User modified xyz entry.', ['user'=>1])
}

Answer 3

现在以更简单的方式支持这一点

1. 创建频道

   转到： root/config/logging.php ，在channels数组下添加您的自定义频道即

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

2. 在您的路由或控制器中写入此日志

    Log::channel('payments')->info('A transaction has been made!');

3. 支付日志可以在/storage/logs/payments.log找到

Answer 4

您可以尝试重新利用日志功能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);
});

然后在您的代码中，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功能：

• 调试
• 信息
• 通知
• 警告
• 错误
• 关键
• 警报
• 紧急情况

Answer 5

扩展ShQ的回答：

我注意到的一个问题是日志将附加[] [] ，这是LineFormatter.format(); $context和$extra的空数组值LineFormatter.format();

即， vendor/monolog/monolog/src/Monolog/Formatter/LineFormatter.php

有两种方法可以解决这个问题，要么提供一种格式，该格式不包括LineFormatter的构造函数的额外或上下文，要么提供第四个参数$ignoreEmptyContextAndExtra = true 。

ShQ 的答案中的所有文件都保持不变，但ChannelStreamHandler必须更改。

通道流处理器：

<?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);
        }
    }

}

重要的变化是提供 true 的第四个参数，即$ignoreEmptyContextAndExtra 。 此参数告诉LineFormatter如果为空，则忽略extra数组的任一context ：

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

您还必须确保运行 monolog 1.22，因为它包含有关ignoreEmptyContextAndExtra的错误修复。

我还在ChannelWritter类中添加了 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“延迟加载记录器”不满意，因此修改为使用服务提供商/IoC

替换ChannelWriter.writeLog() ：

public function writeLog(string $channel, string $level, string $message, array $context = [])
{
    if (!in_array($channel, array_keys($this->channels))) {
        throw new InvalidArgumentException('Invalid channel used.');
    }

    $logger = \App::make("{$channel}log");
    $channelHandler = new ChannelStreamHandler(
        $channel,
        storage_path() . '/' . $this->channels[$channel]['path'],
        $this->channels[$channel]['level']
    );
    $logger->pushHandler($channelHandler);
    $logger->{$level}($message);
}

并在您的AppServiceProvider ：

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

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

我会试着把它捆绑成一个包。

Answer 6

将日志输出到不同文件的最快方法

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

Answer 7

对于 Laravel 5.3 中的我，我不确定它是否是我之前的安装，但我发现 bootstrap/app.php 对我不起作用。

我需要把它放在 app/Providers/AppServiceProvider.php 中。

nb 这是我之前从 config 设置日志级别的地方，所以我最终得到了 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);

}

Answer 8

基于 ShQ 的答案，一个更短更简单的记录器助手，它允许您即时登录到自定义文件。 您还可以添加自定义处理程序并设置文件路径。

App\\Providers\\AppServiceProvider.php（添加注册功能）

//Facade to Object binding
$this->app->bind('LogToChannels', 'App\Helpers\LogToChannels');

config\\app.php（添加到别名）

// Custom Alias Class
'Log' => App\Contracts\Facades\LogToChannels::class

然后你可以在你的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自定义记录器输出

Log::addChannel('channel_name', $customHandler);

当您在应用程序的任何位置调用它的名称时，它就可以访问。

Answer 9

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 :)

Answer 10

我管理了我自己的日志函数，它可以放在 app 目录的 helper.php 文件中。

if ( ! function_exists( 'write_log' ) ) {
    /**
     * Write log to log file
     *

        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'
