努力将我的 node.js 应用程序上传到天蓝色

Question

我是 node.js 的初学者，需要在 Azure 服务器上托管我没有亲自编写的应用程序进行一些测试。该站点在本地托管以及使用 ngrok 托管时运行良好。然而，当我在 azure 上托管它时，我收到以下错误：

[1] 2020-08-23T00:26:36 
Container etuition_0_41152ef3 didn't respond to HTTP pings on port: 8080, failing site start
[2] 2020-08-23T00:26:36 
Container etuition_0_41152ef3 for site etuition did not start within expected time limit.

现在我必须强调，我对 node.js 完全不熟悉，但对我来说，http 请求似乎排列正确。这是我的 index.js 的代码，我认为问题可能出在哪里。

'use strict';

/**

 * variables should be set:

 */
require('dotenv').load();

const express = require('express');
const http = require('https');
const path = require('path');
const { jwt: { AccessToken } } = require('twilio');

const VideoGrant = AccessToken.VideoGrant;

// Max. period that a Participant is allowed to be in a Room (currently 14400 seconds or 4 hours)
const MAX_ALLOWED_SESSION_DURATION = 14400;

// Create Express webapp.

].forEach(example => {
  const examplePath = path.join(__dirname, `../examples/${example}/public`);
  app.use(`/${example}`, express.static(examplePath));
});

const quickstartPath = path.join(__dirname, '../quickstart/public');
app.use('/quickstart', express.static(quickstartPath));

// Set up the path for the examples page.
const examplesPath = path.join(__dirname, '../examples');
app.use('/examples', express.static(examplesPath));

/**

 */
app.get('/', (request, response) => {
  response.redirect('/quickstart');
});



/**

 * username for the client requesting a token, and takes a device ID as a query
 * parameter.
 */
app.get('/token', function(request, response) {
  const { identity } = request.query;

  // Create an access token which we will sign and return to the client,
  // containing the grant we just created.
  const token = new AccessToken(
    process.env.TWILIO_ACCOUNT_SID,
    process.env.TWILIO_API_KEY,
    process.env.TWILIO_API_SECRET,
    { ttl: MAX_ALLOWED_SESSION_DURATION }
  );

  // Assign the generated identity to the token.
  token.identity = identity;

  // Grant the access token Twilio Video capabilities.
  const grant = new VideoGrant();
  token.addGrant(grant);

  // Serialize the token to a JWT string.
  response.send(token.toJwt());
});

// Create http server and run it.
const server = http.createServer(app);
const port = process.env.PORT || 8080;
server.listen(port, function() {
  console.log('Express server running on *:' + port);
});

这是我的 package.json

首先，确定您使用的是什么服务，AWS 或 Azure Web App Services？

无论您使用什么服务，我都建议您使用 git 来部署您的网络应用程序。

1. Use git to deploy in azure web app services.

2. Use git to deploy in aws.

您只需确保您的网络应用程序可以在本地成功运行。您使用的端口如app.set('port', process.env.PORT || 3000); 或const port = process.env.PORT || 3000。这意味着您可以使用 3000 端口在本地成功运行。

更多详情，您可以在另一篇文章中查看我的回答。
