Question

我们可以在laravel 5.2中为不同目的创建自定义日志文件就像订单相关的日志条目应该在order.log和付款相关的东西，条目应该记录在payments.log

我想找到最好的Laravel方式。

目前我们只能更改日志文件的频率（如每日，单一）或者我们可以更改默认日志文件的名称，即laravel.log

Answer 1

有一种简单的方法：

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

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

$orderLog = new Logger(order);
$orderLog->pushHandler(new StreamHandler(storage_path('logs/order.log')), Logger::INFO);
$orderLog->info('OrderLog', $log);

在logs / order.log中输出：

[2017-04-30 00:00:00] order.INFO: OrderLog {"orderId":10, "description":"Some description"} []

Answer 2

在这里，你去了...我花了很多时间为Monolog添加自定义功能，能够以适当的方式做到这一点。我尝试了许多不同的方式，但都有点hacky。最后，我找到了一种让这项功能正常工作的好方法......

由于应用程序很大，我需要单独的日志文件，并尽可能地维护现有的Laravel的Log界面。我需要类似的东西：

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（添加到注册功能）

//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,

应用\合同\外墙\ 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'; } }

应用\助手\ 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() {} /** * Write to log based on the given channel and log level set * * @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]); } } }

应用\助手\ 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：

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

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：

DEBUG
INFO
注意
警告
ERROR
CRITICAL
ALERT
EMERGENCY

Answer 4

扩展ShQ的答案：

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

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

有两种解决方法，要么提供一种格式，不包含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。

<强> 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);
        }
    }

}

重要的变化是提供第4个真实的参数，即$ignoreEmptyContextAndExtra。这个参数告诉LineFormatter如果为空，则忽略context个extra数组：

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

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

我还为ChannelWritter类添加了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“懒惰的负载记录器”＆＃34;并不满意。在ShQ的解决方案中，如此修改以使用服务提供商/ 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);
}

和您的AppServiceProvider：

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

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

我会尝试将它们捆绑在一起打包。

Answer 5

现在可以更轻松地支持此功能

创建频道

转到：root/config/logging.php，在channels数组下，添加您的自定义渠道，即

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

在您的路线或控制器中写入此日志

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

可以在/storage/logs/payments.log

注意：可扩展以进一步满足您的要求

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

对于我来说，在Laravel 5.3中，我不确定它是否是我以前的安装，但我发现bootstrap / app.php对我不起作用。

我需要将它放在app / Providers / AppServiceProvider.php中。

n.b。这是我之前从配置中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);

}

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

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 :)

    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);
            }
        }
    }
}
