写个了网页关键词检测，从此传家宝不再错过

addEventListener(“scheduled”, event => {   event.waitUntil(checkKeywordsAndNotify()); }); async function checkKeywordsAndNotify() {   const url = ‘https://hostloc.com’;  // 要检测的网页URL   const keyword = ‘全球主机交流’;  // 要检测的关键词   const telegramToken = ‘##’;  // TG机器人Token   const chatId = ‘##’;  //要推送的TG用户ID      try {     const urlWithTimestamp = `${url}?t=${Date.now()}`;         const response = await fetch(urlWithTimestamp, {       method: ‘GET’,       headers: {         ‘Cache-Control’: ‘no-cache’,         ‘Pragma’: ‘no-cache’       }     });     const text = await response.text();     if (!text.includes(keyword)) {       await sendTelegramNotification(telegramToken, chatId, `关键词 “${keyword}” 已从 ${url} 上消失`);     }   } catch (error) {     await sendTelegramNotification(telegramToken, chatId, `获取或处理URL时出错: ${error.message}`);   } } async function sendTelegramNotification(token, chatId, message) {   const telegramUrl = `https://api.telegram.org/bot${token}/sendMessage`;   const response = await fetch(telegramUrl, {     method: ‘POST’,     headers: { ‘Content-Type’: ‘application/json’ },     body: JSON.stringify({       chat_id: chatId,       text: message     })   });   return response.json(); }复制代码 1，无需服务器，丢进cloudflare的workers 2，设定→触发程序→Cron 可以检测传家宝是否补货，也可以检测自己的网站是不是掉线了
