基于子域在CakePHP 3中设置默认前缀

我想构建多个子域，这些子域指向CakePHP v3的相同源代码

情况是

若域是“admin.localhost.com”，那个么前缀值应该是admin

如果域是“xyz.localhost.com”、“abc.localhost.com”或子域上的任何域，则前缀值应为vendor

若域是“localhost.com”或“www.localhost.com”，那个么前缀值应该是false，就像cakephp 3默认值一样

我试着从CakePHP3文档中查找数据。但我不知道如何设置默认前缀

提前谢谢

我自己得到了问题的答案

我们必须在

config/routs.php

中通过分解

HTTP\u主机来设置前缀

$exp_domain= explode(".",env("HTTP_HOST"));

$default_prefix=false; // default prefix is false
if(count($exp_domain)>2 && $exp_domain[0]!="www")
{
    if($exp_domain[0]=="admin") $default_prefix="admin"; 
    else $default_prefix="vendor";
}

if($default_prefix=="admin")
{
    // default routes  for vendor users with base scope and pass prefix as admin ($default_prefix)
    Router::scope('/', function ($routes) use($default_prefix) {
        $routes->connect('/', ['controller' => 'admins', 'action' => 'dashboard','prefix'=>$default_prefix]);
        $routes->connect('/:action', ['controller' => 'admins','prefix'=>$default_prefix]);
        $routes->connect('/:controller/:action', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
        $routes->connect('/:controller/:action/*', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);

    });

}
else if($default_prefix=="vendor")
{
    // default routes  for vendor users with base scope and pass prefix as vendor ($default_prefix)
    Router::scope('/', function ($routes) use($default_prefix) {
        $routes->connect('/', ['controller' => 'vendors', 'action' => 'dashboard','prefix'=>$default_prefix]);
        $routes->connect('/:action', ['controller' => 'vendors','prefix'=>$default_prefix]);
        $routes->connect('/:controller/:action', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
        $routes->connect('/:controller/:action/*', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
    });
}
else
{
    // default routes  for normal users with base scope
    Router::scope('/', function ($routes) use($default_prefix) {
        $routes->connect('/', ['controller' => 'users', 'action' => 'dashboard');
        $routes->connect('/:action', ['controller' => 'users');
        $routes->connect('/:controller/:action', ['controller' => 'controller', 'action' => 'action');
        $routes->connect('/:controller/:action/*', ['controller' => 'controller', 'action' => 'action');
    });
}

所以主要的技巧是需要在根作用域上传递前缀。
