laravel 5.2のように、order.logにある注文関連のログエントリや支払い関連のもののエントリがpayments.logに記録されるようにするなど、さまざまな目的でカスタムログファイルを作成できますか
可能な限り最高のLaravel方法を見つけたい。
現在、ログファイルの頻度(毎日、単一など)のみを変更できます。または、デフォルト以外のログファイルの名前、つまりlaravel.logを変更できます。
簡単な方法があります:
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);
Logs/order.logの出力:
[2017-04-30 00:00:00] order.INFO: OrderLog {"orderId":10, "description":"Some description"} []
ここに行きます...適切な方法でそれを行うことができるカスタム機能をMonologに追加するのに多くの時間を費やしました。いろいろな方法を試しましたが、すべてが少しハックしました。最後に、この機能を動作させる良い方法を見つけました。
アプリケーションが大きいので、個別のログファイルが必要で、既存のLaravelのLogインターフェイスを可能な限り維持します。私は次のようなものが必要でした:
Log::write('audit', 'User logged in to the app.');
Log::info('event', 'User sent out 2 emails.');
ソリューション:
App\Providers\AppServiceProvider.php(関数を登録するために追加)
//Facade to Object binding
$this->app->bind('chanellog', 'App\Helpers\ChannelWriter');
config\app.php(エイリアスに追加)
//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() {}
/**
* 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]);
}
}
}
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
);
}
}
}
この後、任意のファイルで実行できます。
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])
}
ログ関数を再利用して、さまざまな種類のログをさまざまなファイルに書き込むことができます。これは、bootstrap/app.php
ファイル:
$app->configureMonologUsing(function($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);
});
次に、コードで次のことができます。
Log::info('Order was created', ['ORDER-123']);
Log::warning('User login', ['USER-1']);
このメソッドを使用して、使用可能なすべてのログ機能を編集できます。
これは現在、はるかに簡単な方法でサポートされています
チャンネルを作成する
goto:root/config/logging.php
、channels
配列の下にカスタムチャネル、つまり
'payments' => 'driver' => 'single'、 'path' => storage_path( 'logs/payments.log')、 'level' = > 'info'、 、
ルートまたはコントローラーでこのログに書き込みます
Log::channel('payments')->info('A transaction has been made!');
支払いログは/storage/logs/payments.log
注:拡張して要件を満たすために拡張可能
Laravelバージョン5.6 ドキュメント
ShQの答えを拡張するには:
私が気づいた1つの問題は、LineFormatter.format();
内の_[] []
_および_$context
_の空の配列値である_$extra
_がログに追加されることです。
すなわち、_vendor/monolog/monolog/src/Monolog/Formatter/LineFormatter.php
_
これを回避する方法は2つあります。LineFormatter
のコンストラクターに追加またはコンテキストを含まない形式を提供するか、4番目の引数_$ignoreEmptyContextAndExtra
_ = true
を提供します。
ShQの回答内のすべてのファイルは同じままですが、ChannelStreamHandler
を変更する必要があります。
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'] >= $this->level);
}
}
}
_
重要な変更は、trueの4番目のパラメーターである_$ignoreEmptyContextAndExtra
_を提供することです。このパラメーターは、空の場合、LineFormatter
配列またはcontext
配列のいずれかを無視するようextra
に指示します。
_$formatter = new LineFormatter(null, null, false, true);
$this->setFormatter($formatter);
_
また、実行中のmonolog 1.22には、ignoreEmptyContextAndExtra
に関するバグ修正が含まれていることを確認する必要があります。
Info()のオーバーライドをChannelWritter
クラスに追加しました:
_public function info($channel, $message, array $context = [])
{
$level = array_flip($this->levels)[$this->channels[$channel]['level']];
$this->writeLog($channel, $level, $message, $context);
}
_
さらに、サービスプロバイダー/ IoCを使用するように変更されたShQのソリューションの「遅延ロードロガー」に満足していませんでした
ChannelWriter.writeLog()
を置き換えます:
_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);
}
_
AppServiceProvider
で:
_ $this->app->bind('eventlog', function () {
return new Logger('event');
});
$this->app->bind('auditlog', function () {
return new Logger('audit');
});
_
これをパッケージにまとめてみます。
ログを異なるファイルに出力する最も簡単な方法
Log::useFiles('path/to/file.log');
Log::info('Info');
App dirのhelper.phpファイルに入れることができる独自のログ機能を管理しました。
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);
}
}
}
}
必要に応じて、パスlaravelInstallDir()。 '../debug.log'を調整してください
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 :)
ShQの回答に基づいて、その場でカスタムファイルにログを記録できる、より短くシンプルなロガーヘルパー。カスタムハンドラを追加して、ファイルパスを設定することもできます。

その後、アプリのどこにでも電話をかけることができます
Log::info('logger_name', 'Log message');
Log::error('other_logger_name', 'Log message', $someContext);
を呼び出すことでロガー出力をカスタマイズすることもできます
Log::addChannel('channel_name', $customHandler);
また、アプリ内のどこからでも名前を呼び出すと、アクセス可能になります。
Laravel 5.3の場合、以前にインストールしたかどうかはわかりませんが、bootstrap/app.phpが機能しなかったことがわかりました。
これをapp/Providers/AppServiceProvider.phpに配置する必要がありました。
n.b.これは以前にconfigからログレベルを設定していた場所なので、3つのログハンドラーになります。
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);
