【问题描述】:
我设置了一个 firebase 函数来向我的机器人发送消息。但是当 firebase 收到请求时,我可以看到发生了一些错误。
FetchError: request to https://api.telegram.org/bot<BOT-TOKEN>/getMe failed, reason: getaddrinfo EAI_AGAIN api.telegram.org:443
at ClientRequest.<anonymous> (/srv/node_modules/node-fetch/lib/index.js:1453:11)
at emitOne (events.js:116:13)
at ClientRequest.emit (events.js:211:7)
at TLSSocket.socketErrorListener (_http_client.js:401:9)

at _combinedTickCallback (internal/process/next_tick.js:139:11)
at process._tickDomainCallback (internal/process/next_tick.js:219:9)
和
Error: Can't set headers after they are sent.
at validateHeader (_http_outgoing.js:491:11)
at ServerResponse.setHeader (_http_outgoing.js:498:3)
at ServerResponse.header (/worker/node_modules/express/lib/response.js:767:10)
at ServerResponse.contentType (/worker/node_modules/express/lib/response.js:595:15)

at /srv/index.js:30:13
at <anonymous>
at process._tickDomainCallback (internal/process/next_tick.js:229:7)
但我认为第二个不会影响结果。
因此,我的 to Bot 没有收到任何消息。
我使用的下一个脚本:
const functions = require('firebase-functions');
const telegraf = require('telegraf');
const axios = require('axios');
const bot = new telegraf('<BOT-TOKEN>')
bot.start((ctx) => ctx.reply('Welcome!'))
bot.help((ctx) => ctx.reply('Send me a sticker'))
bot.on('sticker', (ctx) => ctx.reply('????'))
bot.hears('hi', (ctx) => ctx.reply('Hey there'))
bot.launch()
exports.helloWorld = functions.https.onRequest((request, res) => {
const token = '<BOT-TOKEN>';
const url = `https://api.telegram.org/bot${token}/sendMessage`;
axios.post(url, {
chat_id: '154866113',
text: "just do it!"
})
.then(function (response) {
console.log(response);
res.send({ status: "O"});
return 'ok';
})
.catch(function (error) {
console.log(error);
res.sendStatus(500);
});
res.send("Hello from Firebase!");
});
【问题讨论】:
-
我对电报机器人一无所知,但你在云函数本身之外调用一些方法(例如 bot.start())似乎很奇怪。这些方法什么时候执行?
