路由配置文件 route.php
~~~
return [
//'路由规则2'=>['路由地址和参数','匹配参数（数组）','变量规则（数组）']
'test/:id' => 'index/index/index',
//域名部署
// '二级域名' => '项目文件目录'
'__domain__'=>[
'admin' => 'admin',
]
];
~~~
**代码示例**
定义路由 http://www.blockphp.com/art/id/1.html 等于 http://www.blockphp.com/index/article/show/id/1.html
```
'art/:id' => 'index/aritle/show',
```
:id 为必传参数，如果是选择性传参，则写成[:/id]
> 二域名部署
二级域名admin绑定app/admin模块
http://www.blockphp.com/admin/index/index.html 等于 http://admin.blockphp.com/index/index.html
```
'__domain__'=>[
'admin' => 'admin',
]
```
