在index模块下index控制器中定义了today和hello 方法，但是总是报错不知道为什么
public function hello($name = 'world')
{
echo "hello:".$name;
echo "<br/>";
print_r($this->request->param());
}

public function today($year='2018', $month='9')
{

echo "今天是 $year 年 $month 月";
print_r($this->request->param());
return 'index2';
}

[0] HttpException in Route.php line 1218
非法请求:index/index/today
