laravel 记录慢sql日志

#在appProvidersAppServiceProvider.php里面，boot方法里写

use IlluminateSupportFacadesDB;
public function boot()

{
        DB::listen(function($query){
            try {
                $sql = $query->sql;
                $bingings = $query->bindings;
                $time = $query->time;
                //时间超过1000ms(1s)的做记录
                $msg = compact('sql', 'bingings', 'time');

                $sql_type = substr($sql, 0, 6);//sql类型 增删改查
                //慢sql规则,根据不同语句判断慢不慢

                $slow_rule = ['select' => 1000, 'insert' => 100, 'update' => 100, 'delete' => 100];
                $maxTime = $slow_rule[$sql_type] ?? 100;
                if ($time >= $maxTime) {
                    LogUtil::LogDiyInfo($msg, 'slowlySql/' . $sql_type);
                }
            }catch (Exception $exception){
                $msg = Common::genErrMsg($exception);
                LogUtil::writeLoc($msg,__CLASS__,__FUNCTION__,true);
            }
        });

}




注1:LogDiyInfo方法

public static function LogDiyInfo($msg,$file_name='info'){
    Blogger::info($msg,$file_name);
}
注2:genErrMsg方法

public static function genErrMsg(Exception $e){
    $err_arr = [
        'msg'=>$e->getMessage(),
        'file'=>$e->getFile(),
        'line'=>$e->getLine(),
    ];
    return json_encode($err_arr,JSON_UNESCAPED_UNICODE);
}

注3：writeLoc方法

public static function writeLoc($msg,$class,$func,$is_err=false){
    $class = str_replace('\','/',$class);
    $class_arr = explode('/',$class);
    $file_name = 'writeLoc/'.array_pop($class_arr);
    $msg = $class.'->'.$func.'()::'.$msg;
    if($is_err===true){
        self::LogDiyErr($msg,$file_name);
    }else{
        self::LogDiyInfo($msg,$file_name);
    }
}

注4：Blogger类

namespace AppLibraries;
use IlluminateLogWriter;
use MonologLogger;
class Blogger
{
    public static function __callStatic($name,$arguments) {
        $msg = $arguments[0];
        $file_name = isset($arguments[1])?$arguments[1]:$name;//获取文件名称，默认以日志类型作为日志文件名
        $log= new Writer(new Logger(config('app.env')));
        $log->useFiles(storage_path().'/logs/'.$file_name.'.log');//每个错误类型一个文件
        $log->$name($msg);
    }
