我们可以在 laravel 5.2 中为不同目的创建自定义日志文件吗 就像订单相关的日志条目应该在 order.log 中，对于支付相关的东西，条目应该登录到 payment.log 中
我想找到最好的 Laravel 方式。
目前我们只能更改日志文件频率（如每天，单个），或者我们可以更改日志文件的名称，而不是默认的，即 laravel.log
【问题讨论】：
Log::useFiles() 并指定文件名？如果是这样，Laravel 的 5.2 API docs 会谈论它。

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);
});
然后在你的代码中，你可以这样做：
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：
【讨论】：
storage_path("/logs/orders.log") 行更改为env('LOG_PATH', storage_path("/logs/orders.log"))，这样如果没有定义环境，日志可以回退到 storage_path。
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，但都有点老套。最后我找到了一个让这个功能正常工作的好方法......
由于应用程序很大，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;
/**

class ChannelLog extends Facade
{
/**

*
* @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.
*

protected $channels = [
'event' => [

'audit' => [

];
public function __construct() {}
/**

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
);
}
}
}
之后，你可以在任何文件中做：
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])
}

[] [] 问题的回答。这是因为它使用带有默认格式化程序的默认 LineFormatter.php 实例
对于我在 Laravel 5.3 中，我不确定它是否是我之前安装的，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。
n.b.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);
}
【讨论】：
扩展 ShQ 的回答：
我注意到的一个问题是日志将附加[] []，它们是LineFormatter.format(); 中$context 和$extra 的空数组值
即vendor/monolog/monolog/src/Monolog/Formatter/LineFormatter.php
有两种方法可以解决这个问题，要么为LineFormatter 的构造函数提供不包含额外内容或上下文的格式，要么提供第四个参数$ignoreEmptyContextAndExtra = true。
ShQ 答案中的所有文件保持不变，但 ChannelStreamHandler 必须更改。
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'] >= $this->level);
}
}
}
重要的变化是提供了第四个 true 参数，即$ignoreEmptyContextAndExtra。此参数告诉LineFormatter 如果为空，则忽略context 或extra 数组：
$formatter = new LineFormatter(null, null, false, true);
$this->setFormatter($formatter);
您还必须确保您正在运行独白 1.22，因为它包含关于 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);
}
在你的AppServiceProvider:
$this->app->bind('eventlog', function () {
return new Logger('event');
});
$this->app->bind('auditlog', function () {
return new Logger('audit');
});
我会试着把它打包成一个包。
【讨论】：
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);
logs/order.log 中的输出：
[2017-04-30 00:00:00] order.INFO: OrderLog {"orderId":10, "description":"Some description"} []
【讨论】：
Logger() 将字符串作为类构造函数参数（至少在 laravel 5.5.28 中）。所以对于 5.5.28，正确的方法是 Logger('order') （我刚刚尝试过干净的 laravel 5.5.28 项目）。我不确切知道您是否犯了错误，所以我不编辑您的答案，而是写评论。我什至无法编辑，因为编辑可能至少修改了 6 个字符）
基于 ShQ 的答案，一个更短更简单的记录器助手，允许您即时记录到自定义文件。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）

'Log' => App\Contracts\Facades\LogToChannels::class
然后您可以在应用中的任何位置调用
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);
当您在应用中的任何位置调用它的名称时，它就会被访问。

Log::info('log message', $destinationPath);会很棒
将日志输出到不同文件的最快方法
Log::useFiles('path/to/file.log');
Log::info('Info');

现在以更简单的方式支持此功能
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

laravel.EMERGENCY: Unable to create configured logger. Using emergency logger.
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 :)
