TP5.0 API自定义错误信息,异常基类

新建文件夹 \application\lib\exception
创建异常基类BaseException.php 继承 Exception 异常类

	namespace app\lib\exception;
	use think\Exception;
	
	/**
	 * Class BaseException
	 * 自定义异常类的基类
	 */
	class BaseException extends Exception
	{
    
    
	    public $code = 400;
	    public $msg = '无效请求';
	    public $errorCode = 999;
	
	    public $shouldToClient = true;
	
	    /**
	     * 构造函数,接收一个关联数组
	     * @param array $params 关联数组只应包含code、msg和errorCode,且不应该是空值
	     */
	    public function __construct($params=[])
	    {
    
    
	        if(!is_array($params)){
    
    
	            return;
	        }
	        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'];
	        }
	    }
	}

创建异常误类ExceptionHandler.php 继承 新建的异常基类BaseException

	namespace app\lib\exception;
	
	use Exception;
	use think\exception\Handle;
	use think\Log;
	use think\Request;
	
	class ExceptionHandler extends Handle
	{
    
    
	    private $code;
	    private $msg;
	    private $errorCode;
	
	    public function render(Exception $e)
	    {
    
    
	
	        if ($e instanceof BaseException)
	        {
    
    
	            //如果是自定义异常,则控制http状态码,不需要记录日志
	            //因为这些通常是因为客户端传递参数错误或者是用户请求造成的异常
	            //不应当记录日志
	
	            $this->code = $e->code;
	            $this->msg = $e->msg;
	            $this->errorCode = $e->errorCode;
	        }
	        else{
    
    
	            // 如果是服务器未处理的异常,将http状态码设置为500,并记录日志
	            if(config('app_debug')){
    
    
	                // 调试状态下需要显示TP默认的异常页面,因为TP的默认页面
	                // 很容易看出问题
	                return parent::render($e);
	            }
	            $this->code = 500;
	            $this->msg = '内部错误';
	            $this->errorCode = 999;
	            $this->recordErrorLog($e);
	        }
	
	        $request = Request::instance();
	        $result = [
	            'msg'  => $this->msg,
	            'error_code' => $this->errorCode,
	            'request_url' => $request = $request->url()
	        ];
	
	        return json($result, $this->code);
	    }
	
	    /*
	     * 将异常写入日志
	     */
	    private function recordErrorLog(Exception $e)
	    {
    
    
	        Log::init([
	            'type'  =>  'File',
	            'path'  =>  LOG_PATH,
	            'level' => ['error']
	        ]);
	//        Log::record($e->getTraceAsString());
	        Log::record($e->getMessage(),'error');
	    }
	}

修改 config.php 下的 异常处理handle类
'exception_handle' => '\app\lib\exception\ExceptionHandler',
