前言
因为Telegram的api在国内无法访问,所以一般都需要使用代理。本文使用CloudflareWorker部署Api代理(主要是能白嫖)。
开始操作
1. 点击左侧Worker

2. 创建服务

名称随便填写,启动器选择HTTP路由器

return resp;
}
/**

*/
addEventListener('fetch', (event) => {
event.respondWith(handleRequest(event.request));
});
然后保存并部署,之后可以在触发器中添加自己的域名

如何使用
只需要把telegram api地址替换成 https://yourdomain.xxx
即可
