Log processing

Logger

After easyswoole 3.2.3, the default log processing class of easyswoole is separated into component form and component address：https://github.com/easy-swoole/log

Custom log

First, define a log template, which needs to be inherited and implemented\EasySwoole\Log\LoggerInterface，as follows：


<?php
/**
 * Created by PhpStorm.
 * User: root
 * Date: 19-11-13
 * Time: 上午11:00
 */

namespace App\Logger;

use EasySwoole\Log\LoggerInterface;

class Logger implements LoggerInterface
{

    function log(?string $msg, int $logLevel = self::LOG_LEVEL_INFO, string $category = 'DEBUG'): string
    {
        // TODO: Implement log() method.
        $date = date('Y-m-d H:i:s');
        $levelStr = $this->levelMap($logLevel);
        $filePath = EASYSWOOLE_LOG_DIR."/".date('Y-m-d').".log";
        $str = "[{$date}][{$category}][{$levelStr}] : [{$msg}]\n";
        file_put_contents($filePath,"{$str}",FILE_APPEND|LOCK_EX);
        return $str;
    }

    function console(?string $msg, int $logLevel = self::LOG_LEVEL_INFO, string $category = 'DEBUG')
    {
        // TODO: Implement console() method.
        $date = date('Y-m-d H:i:s');
        $levelStr = $this->levelMap($logLevel);
        $temp =  $this->colorString("[{$date}][{$category}][{$levelStr}] : [{$msg}]",$logLevel)."\n";
        fwrite(STDOUT,$temp);
    }

    private function colorString(string $str,int $logLevel)
    {
        switch($logLevel) {
            case self::LOG_LEVEL_INFO:
                $out = "[42m";
                break;
            case self::LOG_LEVEL_NOTICE:
                $out = "[43m";
                break;
            case self::LOG_LEVEL_WARNING:
                $out = "[45m";
                break;
            case self::LOG_LEVEL_ERROR:
                $out = "[41m";
                break;
            default:
                $out = "[42m";
                break;
        }
        return chr(27) . "$out" . "{$str}" . chr(27) . "[0m";
    }

    private function levelMap(int $level)
    {
        switch ($level)
        {
            case self::LOG_LEVEL_INFO:
                return 'INFO';
            case self::LOG_LEVEL_NOTICE:
                return 'NOTICE';
            case self::LOG_LEVEL_WARNING:
                return 'WARNING';
            case self::LOG_LEVEL_ERROR:
                return 'ERROR';
            default:
                return 'UNKNOWN';
        }
    }
}

In theEasySwooleEvent initialize into the user-defined log processing， as follows：


public static function initialize()
{
    // TODO: Implement initialize() method.

    Di::getInstance()->set(SysConst::LOGGER_HANDLER, new \App\Logger\Logger());

}

Logger call method

use use EasySwoole\EasySwoole\Logger;
Logger::getInstance()->log('log level info',Logger::LOG_LEVEL_INFO,'DEBUG');//Record the info level log the default values of the next two parameters in the example
Logger::getInstance()->log('log level notice',Logger::LOG_LEVEL_NOTICE,'DEBUG2');//Record the notice level log the default values of the next two parameters in the example
Logger::getInstance()->console('console',Logger::LOG_LEVEL_INFO,'DEBUG');//Log info level and output to console
Logger::getInstance()->info('log level info');//Log info level and output to console
Logger::getInstance()->notice('log level notice');//Log notice level and output to console
Logger::getInstance()->waring('log level waring');//Log warning level and output to console
Logger::getInstance()->error('log level error');//Log error level and output to console
Logger::getInstance()->onLog()->set('myHook',function ($msg,$logLevel,$category){
    //Add callback function after log writing
});

Note that for non framework use, such as unit test scripts, execute EasySwoole\EasySwoole\Core::getInstance()->initialize(); Used to initialize logs

>=3.3.7:EasySwoole\EasySwoole\Core::getInstance()->initialize()->globalInitialize();

The following will be output / recorded:

[2019-06-01 21:10:25][DEBUG][INFO] : [1]
[2019-06-01 21:10:25][DEBUG][INFO] : [2]
[2019-06-01 21:10:25][DEBUG][INFO] : [3]
[2019-06-01 21:10:25][DEBUG][NOTICE] : [4]
[2019-06-01 21:10:25][DEBUG][WARNING] : [5]
[2019-06-01 21:10:25][DEBUG][ERROR] : [6]
[2019-06-01 21:23:27][DEBUG][INFO] : [log level info]
[2019-06-01 21:23:27][DEBUG2][NOTICE] : [log level notice]
[2019-06-01 21:23:27][DEBUG][INFO] : [console]
[2019-06-01 21:23:27][DEBUG][INFO] : [log level info]
[2019-06-01 21:23:27][DEBUG][NOTICE] : [log level notice]
[2019-06-01 21:23:27][DEBUG][WARNING] : [log level waring]
[2019-06-01 21:23:27][DEBUG][ERROR] : [log level error]

In the new logger processing scheme, new LOG_LEVEL_INFO = 1，LOG_LEVEL_NOTICE = 2，LOG_LEVEL_WARNING = 3，LOG_LEVEL_ERROR = 4，4 log levels to help distinguish logs better

Trigger

\EasySwoole\EasySwoole\TriggerTrigger, which is used to actively trigger an error or exception without interrupting the program execution.

After easyswoole version 3.2.3, the default trigger class of easyswoole is separated into component form. The component address is:：https://github.com/easy-swoole/trigger

For example, in the onexception of the controller, we can record the error exception, and then output other contents to prevent the system terminal from running and the user from discovering the real error

use EasySwoole\EasySwoole\Trigger;
//Record the error exception log with the level of exception
Trigger::getInstance()->throwable($throwable);
//Record the error information with the level of fatalerror
Trigger::getInstance()->error($throwable->getMessage().'666');

Trigger::getInstance()->onError()->set('myHook',function (){
    //Add callback function when error occurs
});
Trigger::getInstance()->onException()->set('myHook',function (){

});

Log Center

For example, if you want to push data to the log center or the most TCP log, you can add an OnLog callback, and then push the log information to the log center.
