是什么导致我的电报漫游器出现此404错误

如何解决是什么导致我的电报漫游器出现此404错误

const { Composer } = require('micro-bot');
const bot = new Composer;
const Telegram = require('telegraf/telegram')
const http = require('http');
const express = require('express');

const bodyParser = require('body-parser');


const telegram = new Telegram(process.env.BOT_TOKEN);

const app = express();

app.use(bodyParser.urlencoded({ extended: true }));

app.post('/sms',(req,res) => {
  console.log('sms received')

  telegram.sendMessage(process.env.CHANNEL_ID,req.body.Body)


  res.send(req.body.Body);

});


http.createServer(app).listen(3000,() => {
  console.log(`Express server listening on port 3000`);
});



module.exports = bot;

每当我向机器人api发送任何http请求时，我都会从heroku获取此应用程序日志：

at = info方法= POST路径=“ / sms”主机= smsforwarder.herokuapp.com request_id = 5dd30db1-aeb8-4f3f-8d56-0b0b576ef4e6 fwd =“ 116.87.44.71” dyno = web.1 connect = 0ms service = 1ms状态= 404字节= 101协议= https

当我尝试使用环境端口时

const port = process.env.PORT || 3000
http.createServer(app).listen(port,() => {
  console.log(`Express server listening on port ${port}`);
});

我收到一条错误消息，指出该端口已在使用中

解决方法

我找到了解决问题的方法。我有一个procfile，让我的微型机器人在env端口上进行监听，这就是为什么当我让网络服务器同时监听同一端口时，它抛出一个错误，指出该端口已在使用中。
