我们是否可以在laravel 5.2中为不同目的创建自定义日志文件，例如订单相关的日志条目应该在order.log中，对于与付款相关的内容，条目应该记录在payments.log中
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
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);
在logs / order.log中输出：
[2017-04-30 00:00:00] order.INFO: OrderLog {"orderId":10, "description":"Some description"} []
我管理自己的日志功能，可以放在app dir的helper.php文件中。
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 :)
请根据需要调整路径laravelInstallDir（）。'.. / debug.log'
在这里你去...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（添加到注册函数）
//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,
应用程序\合同\外立面\ 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';
}
}
应用程序\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

*/
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]);
}
}
}
应用程序\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])
}
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：
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：
现在，这种方式更容易支持
root/config/logging.php，在channels数组下添加你的自定义频道，即
'payments'=> ['driver'=>'single'，'path'=> storage_path（'logs / payments.log'），'level'=>'info'，]， Log::channel('payments')->info('A transaction has been made!');
/storage/logs/payments.log找到注意：可扩展以进一步增强您的要求

扩展ShQ的答案：
我注意到的一个问题是日志将附加[] []，这是$context中$extra和LineFormatter.format();的空数组值
不，是的zxsw poi
有两种方法可以解决这个问题，或者为vendor/monolog/monolog/src/Monolog/Formatter/LineFormatter.php的构造函数提供一个不包含额外或上下文的格式，或者提供第四个参数LineFormatter = $ignoreEmptyContextAndExtra。
ShQ答案中的所有文件都保持不变，但true必须更改。
ChannelStreamHandler：
ChannelStreamHandler重要的变化是提供第4个真实的参数，即<?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'] >= $this->level);
}
}
}
。这个参数告诉$ignoreEmptyContextAndExtra如果为空则忽略LineFormatter数组的context：
extra您必须确保运行monolog 1.22，因为它包含有关$formatter = new LineFormatter(null, null, false, true);
$this->setFormatter($formatter);
的错误修复。
我还为ignoreEmptyContextAndExtra类添加了info（）的覆盖：
ChannelWritter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public function info($channel, $message, array $context = [])
{
$level = array_flip($this->levels)[$this->channels[$channel]['level']];
$this->writeLog($channel, $level, $message, $context);
}
：
ChannelWriter.writeLog()在你的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我会尝试将它们捆绑在一起。
最快的方式将日志输出到不同的文件
$this->app->bind('eventlog', function () {
return new Logger('event');
});
$this->app->bind('auditlog', function () {
return new Logger('audit');
});
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。
我需要把它放在app / Providers / AppServiceProvider.php中。
注：这是我之前从配置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。
Log::useFiles('path/to/file.log');
Log::info('Info');
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。
