Fatal error: Wrong parameters for Exception([string $exception [, long $code [, Exception $previous = NULL]]]) in C:\xampp\htdocs\tp5disc\application\api\validate\BaseValidate.php on line 31

public function goCheck(){
       //获取http传入的参数
       //对这些参数效验
        $request = Request::instance();
        $params = $request->param();

        $result = $this->batch()->check($params);

        if(!$result){
            $e = new ParameterException([
                'msg' => $this->error,
            ]);
            throw $e;
        }else{
            return true;
        }
    }

完全按照老师写的？

$request = Request::instance();
$params = $request->param();

if (!$this->check($params)){
$e = new ParameterException();
$e->msg = is_array($this->error) ? implode(';', $this->error) : $this->error;
throw $e;
}
return true;

我直接用$e->msg = is_array($this->error) ? implode(';', $this->error) : $this->error;

替代了 $e = new ParameterException([
'msg' => $this->error,
]);

这个就好使了。
