Loading... # 使用Cloudflare Worker代理Telegram Bot Api 总所周知的原因，Telegram的API在国内是用不了的，以前我用的是nginx的反代，但是最近把所有的vps都改为traefik了，又不想再弄一层nginx的反代，就研究了一下使用Cloudflare Worker来反代。反正白嫖的，不用白不用，一天100w次访问也足够个人使用了。 ## 使用前提 <div class="tip inlineBlock success"> 1.一个托管在cloudflare的域名 2.开启cloudflare的免费worker服务 </div> ## 首先登录Cloudflare以后点击左侧的Workers [](https://anerg.com/wp-content/uploads/2022/07/image-4.png) ## 点击创建服务 [](https://anerg.com/wp-content/uploads/2022/07/image-5.png) ## 服务名称随意填写，但是下面需要选择HTTP路由器 [](https://anerg.com/wp-content/uploads/2022/07/image-6.png) ## 创建完成后，点击刚创建的Worker，再点击快速编辑 [](https://anerg.com/wp-content/uploads/2022/07/image-7.png) ## 在左侧红框处删除原有的，填入下面给出的代码 [](https://anerg.com/wp-content/uploads/2022/07/image-8.png) ``` /** * Helper functions to check if the request uses * corresponding method. * */ const Method = (method) => (req) => req.method.toLowerCase() === method.toLowerCase(); const Get = Method('get'); const Post = Method('post'); const Path = (regExp) => (req) => { const url = new URL(req.url); const path = url.pathname; return path.match(regExp) && path.match(regExp)[0] === path; }; /* * The regex to get the bot_token and api_method from request URL * as the first and second backreference respectively. */ const URL_PATH_REGEX = /^\/bot(?<bot_token>[^/]+)\/(?<api_method>[a-z]+)/i; /** * Router handles the logic of what handler is matched given conditions * for each request */ class Router { constructor() { this.routes = []; } handle(conditions, handler) { this.routes.push({ conditions, handler, }); return this; } get(url, handler) { return this.handle([Get, Path(url)], handler); } post(url, handler) { return this.handle([Post, Path(url)], handler); } all(handler) { return this.handler([], handler); } route(req) { const route = this.resolve(req); if (route) { return route.handler(req); } const description = 'No matching route found'; const error_code = 404; return new Response( JSON.stringify({ ok: false, error_code, description, }), { status: error_code, statusText: description, headers: { 'content-type': 'application/json', }, } ); } /** * It returns the matching route that returns true * for all the conditions if any. */ resolve(req) { return this.routes.find((r) => { if (!r.conditions || (Array.isArray(r) && !r.conditions.length)) { return true; } if (typeof r.conditions === 'function') { return r.conditions(req); } return r.conditions.every((c) => c(req)); }); } } /** * Sends a POST request with JSON data to Telegram Bot API * and reads in the response body. * @param {Request} request the incoming request */ async function handler(request) { // Extract the URl method from the request. const { url, ..._request } = request; const { pathname: path, search } = new URL(url); // Leave the first match as we are interested only in backreferences. const { bot_token, api_method } = path.match(URL_PATH_REGEX).groups; // Build the URL const api_url = 'https://api.telegram.org/bot' + bot_token + '/' + api_method + search; // Get the response from API. const response = await fetch(api_url, _request); const result = await response.text(); const res = new Response(result, _request); res.headers.set('Content-Type', 'application/json'); return res; } /** * Handles the incoming request. * @param {Request} request the incoming request. */ async function handleRequest(request) { const r = new Router(); r.get(URL_PATH_REGEX, (req) => handler(req)); r.post(URL_PATH_REGEX, (req) => handler(req)); const resp = await r.route(request); return resp; } /** * Hook into the fetch event. */ addEventListener('fetch', (event) => { event.respondWith(handleRequest(event.request)); }); ``` ## 回到管理后台首页，点击左侧的“网站”，在右侧点击你已托管在Cloudflare的域名 [](https://anerg.com/wp-content/uploads/2022/07/image-9.png) ## 选择该域名下的Workers [](https://anerg.com/wp-content/uploads/2022/07/image-10.png) ## 选择添加路由 [](https://anerg.com/wp-content/uploads/2022/07/image-11.png) ## 在红框处填写你想要用的二级域名，比如：tgapi.test.com/* 注意后面必须是/*结尾，服务选择刚才创建的服务，环境选择production即可 [](https://anerg.com/wp-content/uploads/2022/07/image-12.png) ## 最后保存就可以了。 最后修改：2023 年 01 月 10 日 © 允许规范转载 打赏 赞赏作者 微信 赞 如果觉得我的文章对你有用，别忘了点赞或赞赏，让我知道路上有你陪伴。

二级域名需要解析一个IP?
不用，自动会添加进去
