构建thinkphp5全局异常

1、修改configuration里面的配置

异常处理handle类留空使用 \think\exception\Handle
‘exception_handle’ => ‘app\exception\ExceptionHandler’, //这里是你自己的异常类重写的目录

<?php
/**

Created by PhpStorm.
User: admin
Date: 2018/9/23
Time: 22:43
*/

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

class ExceptionHandler extends Handle
{
private $code;
private $msg;
private $errorCode;
/**继承并重写Exception类
* @param Exception $ex
* @return \think\Response|\think\response\Json
*/

    public function render(\Exception $ex)
    {
        if ($ex instanceof BaseException) {
            $this->msg = $ex->code;
            $this->msg = $ex->msg;
            $this->errorCode = $ex->errorCode;

        } else {
            if ( config('app_debug') ) {
                //显示页面错误，用于开发人员内部开发
             return    parent::render($ex);
            } else {

                $this->code = 500;
            $this->msg = "服务器内部错误 ！";
            $this->errorCode = 999;
            $this->recordErrorLog($ex);
        }
    }
    $result = [
        'errorCode' => $this->errorCode,
        'msg' => $this->msg,
        'request_url' => Request::instance()->url(),
    ];
    return json($result, $this->code);
}

/**   //自定义日志错误记录
 * @param Exception $ex
 */
private function recordErrorLog(\Exception $ex)
{
    Log::init([
        'type' => 'File',
        'path' => LOG_PATH,
        'level' => ['error'],
    ]);
    Log::record($ex->getMessage(), 'error');

}

}

namespace app\exception;

use think\Exception;

restful API 最佳实践
POST 创建
PUT 更新
GET 查询
DELETE 删除
状态码：404（当前请求的页面不存在） 400（当前的参数错误） 200（查询成功！）
201 202（更新成功！） 401（未授权） 403（当前的资源被禁止） 500（服务器未知错误）
错误码：自定义的错误ID号
统一描述错误：错误码、错误信息、当前URL
使用token令牌来授权和验证身份
版本控制
测试与环境分开：api.xxx.com/dev.api.xxx.com
url 语义要明确，最好可以望文生义，最好是有一份比较标准的文档
*/
class BaseException extends Exception
{
public $code=500;
public $msg =“500 内部错误！”;
public $errorCode;

/**
- BaseException constructor.
- @param array $KaTeX parse error: Expected group after '_' at position 27: \dotsublic function _̲_construct($ params = [])
  {
  if (!is_array($params)) {
  return false;
  } else {
  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’];
  }
  }
  }
  }

-------------------------------------------------------------------------

用法

/**

Created by PhpStorm.
User: admin
Date: 2018/9/24
Time: 12:19
*/

namespace app\exception;

class ParameterException extends BaseException
{
public $code = ‘400’;
public $msg= “内部错误”;
public $errorCode = ‘10000’;
}

--------------------------------------------------------------------------------------------

测试

<?php
namespace app\admin\controller;

use app\admin\validate\TestValidate;
use app\exception\TestException;
use think\Exception;

class Index
{
public function index( )
{

    if ( true){
       throw  newParameterException();
  	}
    return json(['code'=>200],'200');
}

}
