const www = new Proxy(new URL('https://www'), { get: function get(target, prop) { let o = Reflect.get(target, prop); if (typeof o === 'function') { return o.bind(target) } if (typeof prop !== 'string') { return o; } if (prop === 'then') { return Promise.prototype.then.bind(fetch(target)); } target = new URL(target); target.hostname += `.${prop}`; return new Proxy(target, { get }); }
});

访问百度

www.baidu.com.then(response => { console.log(response.status); // ==> 200 })

使用 async/await 语法:

const response = await www.baidu.com console.log(response.ok) // ==> true console.log(response.status); // ==> 200
