摘要：配置主域名二級子域名列表項目其中加入了版本控制，使用的是路由傳入方式在路由文件中配置，如下版本路由省略方法名時有方法名時同時控制器里加入版本號這個例子最終的顯示為項目最終目錄結構為配置主域名配置此處可作反向代理二級接口子域名配置配置解決

配置：
   主域名        www.demo.xyz
   二級子域名    api.demo.xyz

列表項目其中api.demo.xyz加入了版本控制，使用的是URL路由傳入方式

在route.php路由文件中配置，如下

return [
    // api版本路由
    ":version/:controller" => ":version.:controller",// 省略方法名時
    ":version/:controller/:function" => ":version.:controller/:function"http:// 有方法名時
];

//同時控制器里加入版本號
namespace appapicontrollerv1;

class User
{
    public function login()
    {
        $data = ["name"=>"Paul","age"=>19];
        return json($data);
    }
}

//這個例子最終的url顯示為http://api.demo.xyz/v1/user
Route::get(":version/user", "api/:version.user/login");

# 其實就是將下面這段配置放到location塊外面

}
