如何让Hapi插件只在特定的域名或子域下工作？

const Hapi = require('hapi');

const server = Hapi.server({
    port: 3000,
    host: 'localhost'
});

const pluginOptions = {
    // 插件的配置选项
};

const plugin = {
    name: 'myPlugin',
    version: '1.0.0',
    register: function (server, options) {
        // 插件的注册逻辑
    }
};

const routes = [
    {
        method: 'GET',
        path: '/',
        vhost: 'example.com', // 只在example.com域名下生效
        handler: function (request, h) {
            // 处理请求的逻辑
            return 'Hello, World!';
        }
    },
    {
        method: 'GET',
        path: '/',
        vhost: 'subdomain.example.com', // 只在subdomain.example.com子域下生效
        handler: function (request, h) {
            // 处理请求的逻辑
            return 'Hello, Subdomain!';
        }
    }
];

const init = async () => {
    await server.register(plugin);

    server.route(routes);

    await server.start();
    console.log('Server running at:', server.info.uri);
};

init();
