TP5 日志系统

由 喜欢而已 提交于 2020-02-18 00:42:50

一、改变日志记录位置

//public的index.php中改变日志保存路径
<?php
// [ 应用入口文件 ]

// 定义应用目录
define('APP_PATH', __DIR__ . '/../application/');

//自定义日志位置  覆盖原来日志位置
define('LOG_PATH', __DIR__ . '/../log/');

// 加载框架引导文件
require __DIR__ . '/../thinkphp/start.php';

      效果

二、在全局异常处理中加入日志系统


//controller 控制器 banner  抛出异常
<?php

namespace app\api\controller\v1;

use app\api\validate\IDMustBePostiveInt;
use app\api\model\Banner as BannerModel;
use app\lib\exception\BannerMissException;
use think\Exception;

class Banner
{
    public function getBanner($id){

        (new IDMustBePostiveInt()) -> goCheck();
        $banner = BannerModel::getBannerById($id);

        if(!$banner){
            //抛出异常   方式一
            throw new Exception('内部错误');

            //抛出异常   方式二   自定义异常
//            throw new BannerMissException();
        }
        return $banner;

    }
}



//调用打印方法 打印日志
<?php

namespace app\lib\exception;

use think\Exception;
use think\exception\Handle;
use think\Log;
use think\Request;

class ExceptionHandler extends Handle
{
    private $code;
    private $msg;
    private $errorCode;
    //客户要返回客户端的URL路径

    public function render(\Exception $e)
    {

        if($e instanceof BaseException){
            //如果是自定义的异常
            $this -> code = $e -> code;
            $this -> msg = $e -> msg;
            $this -> errorCode = $e -> errorCode;

        }else{
            //如果不是自定义的异常
            $this -> code = 500;
            $this -> msg = '服务器内部错误，不想告诉你！';
            $this -> errorCode = 999;
            //打印日志
            $this -> recordErrorLog($e);
        }

        $request = Request::instance();
        $result = [
          'msg' => $this -> msg,
          'error_code' => $this -> errorCode,
          'request_url' => $request -> url()
        ];

        return json($result, $this -> code);
    }

    private function recordErrorLog(Exception $e){
        Log::init([
            'type' => 'File',
            'path' => LOG_PATH,
            'level' => ['error']
        ]);
        Log::record($e -> getMessage(), 'error');
    }
}

 三、根据是否开启调试   判断是否返回具体错误信息页面   config('app_debug')

// 根据是否开启调试   判断是否返回具体错误信息页面   config('app_debug')
<?php

namespace app\lib\exception;

use think\Config;
use think\Exception;
use think\exception\Handle;
use think\Log;
use think\Request;

class ExceptionHandler extends Handle
{
    private $code;
    private $msg;
    private $errorCode;
    //客户要返回客户端的URL路径

    public function render(\Exception $e)
    {

        if($e instanceof BaseException){
            //如果是自定义的异常
            $this -> code = $e -> code;
            $this -> msg = $e -> msg;
            $this -> errorCode = $e -> errorCode;

        }else{

            //Config::get('app_debug');
            if(config('app_debug')){
                //return default error page
                return parent::render($e);
            }else{
                //如果不是自定义的异常
                $this -> code = 500;
                $this -> msg = '服务器内部错误，不想告诉你！';
                $this -> errorCode = 999;
                //打印日志
                $this -> recordErrorLog($e);
            }

        }

        $request = Request::instance();
        $result = [
          'msg' => $this -> msg,
          'error_code' => $this -> errorCode,
          'request_url' => $request -> url()
        ];

        return json($result, $this -> code);
    }

    private function recordErrorLog(Exception $e){
        Log::init([
            'type' => 'File',
            'path' => LOG_PATH,
            'level' => ['error']
        ]);
        Log::record($e -> getMessage(), 'error');
    }
}

四、 兼容验证层异常抛出 

目录

 

//创建参数错误异常  ParameterException  并继承BaseException
<?php

namespace app\lib\exception;


class ParameterException extends BaseException
{
    public $code = 400;
    public $msg = '参数错误';
    public $errorCode = 10000;
}
//BaseException 异常基类
<?php

namespace app\lib\exception;

use think\Exception;

class BaseException extends Exception
{
    //HTTP 状态码 404,200
    public $code = 400;

    //错误具体信息
    public $msg =  '参数错误';

    //自定义的错误码
    public $errorCode = 10000;
}
//控制器
<?php

namespace app\api\controller\v1;

use app\api\validate\IDMustBePostiveInt;
use app\api\model\Banner as BannerModel;
use app\lib\exception\BannerMissException;
use think\Exception;

class Banner
{
    public function getBanner($id){

        (new IDMustBePostiveInt()) -> goCheck();
        //$banner = BannerModel::getBannerById($id);
        //return $banner;

    }
}
//验证层基类 BaseValidate 
<?php

namespace app\api\validate;

use app\lib\exception\ParameterException;
use think\Exception;
use think\Request;
use think\Validate;

class BaseValidate extends Validate
{
    public function goCheck(){
        //获取http传入的参数
        //对这些参数做校验
        $request = Request::instance();
        $params = $request -> param();

        $result = $this -> check($params);
        if(!$result){
            $e = new ParameterException();
            $e -> msg = $this -> getError();
            $e -> errorCode = 10002;
            throw $e;
//            $error = $this->getError();
//            throw new Exception($error);
        }else{
            return true;
        }
    }
}
//IDMustBePostiveInt 参数必须是正整数验证 
<?php

namespace app\api\validate;

class IDMustBePostiveInt extends BaseValidate
{
    protected $rule = [
      'id' => 'require|isPostiveInteger'
    ];

    //field是字段名
    protected function isPostiveInteger($value, $rule = '', $data = '', $field = ''){
        if(is_numeric($value) && is_int($value + 0) && ($value + 0) > 0){
            return true;
        }else{
            return $field.'必须是正整数';
        }
    }
}

五、使用构造函数改造  异常参数传递

//参数传递  使用构造函数   BaseValidate验证器 
<?php

namespace app\api\validate;

use app\lib\exception\ParameterException;
use think\Exception;
use think\Request;
use think\Validate;

class BaseValidate extends Validate
{
    public function goCheck(){
        //获取http传入的参数
        //对这些参数做校验
        $request = Request::instance();
        $params = $request -> param();

        $result = $this -> check($params);
        if(!$result){
            $e = new ParameterException([
                'msg' => '',
                //'code' => 400,
                //'error' => 10002
            ]);
            throw $e;
        }else{
            return true;
        }
    }
}
//构造函数接收参数   参数可选
<?php

namespace app\lib\exception;

use think\Exception;
use Throwable;

class BaseException extends Exception
{
    //HTTP 状态码 404,200
    public $code = 400;

    //错误具体信息
    public $msg =  '参数错误';

    //自定义的错误码
    public $errorCode = 10000;

    public function  __construct($params = [])
    {

       if(!is_array($params)){
           return;
            //throw new Exception('参数必须是数组');
       }

       if(array_key_exists('code', $params)){
            $this -> code = $params['code'];
       }

       if(array_key_exists('msg', $params)){
           $this -> msg = $params['msg'];
       }

       if(array_key_exists('errorCode', $params)){
           $this -> errorCode = $params['errorCode'];
       }

    }
}

六、验证器兼容多个参数错误

//check前使用 batch()方法
<?php

namespace app\api\validate;

use app\lib\exception\ParameterException;
use think\Exception;
use think\Request;
use think\Validate;

class BaseValidate extends Validate
{
    public function goCheck(){
        //获取http传入的参数
        //对这些参数做校验
        $request = Request::instance();
        $params = $request -> param();

        $result = $this -> batch() -> check($params);
        if(!$result){
            $e = new ParameterException([
                'msg' => $this -> error,
//                'code' => 400,
//                'error' => 10002
            ]);
            throw $e;
        }else{
            return true;
        }
    }
}

效果
