Question

我是nodejs的新手，想要从tokbox服务构建api。我想部署，但失败，本地是正常的工作。 Heroku和openshift都得到503错误。你能帮忙解决这个问题吗？ thakns

// Dependencies
var express = require('express'),
     OpenTok = require('opentok');

var server_port = process.env.OPENSHIFT_NODEJS_PORT || 3000
// var server_ip_address = process.env.OPENSHIFT_NODEJS_IP || '127.0.0.1'


// Verify that the API Key and API Secret are defined
var apiKey = "***",
    apiSecret = "*****";
if (!apiKey || !apiSecret) {
  console.log('You must specify API_KEY and API_SECRET environment variables');
  process.exit(1);
}

// Initialize the express app
var app = express();
app.use(express.static(__dirname + '/public'));

// Initialize OpenTok
var opentok = new OpenTok(apiKey, apiSecret);

// Create a session and store it in the express app
opentok.createSession({ mediaMode: 'routed' },function(err, session) {
  if (err) throw err;
  app.set('sessionId', session.sessionId);
  // We will wait on starting the app until this is done
  init();
});

app.get('/', function(req, res) {
  res.render('index.ejs');
});

app.get('/host', function(req, res) {
  var sessionId = app.get('sessionId'),
      // generate a fresh token for this client
      token = opentok.generateToken(sessionId, { role: 'moderator' });

  res.json('host.ejs', {
    apiKey: apiKey,

app.get('/history', function(req, res) {
  var page = req.param('page') || 1,
      offset = (page - 1) * 5;
  opentok.listArchives({ offset: offset, count: 5 }, function(err, archives, count) {
    if (err) return res.send(500, 'Could not list archives. error=' + err.message);
    res.json('history.ejs', {
      archives: archives,
      showPrevious: page > 1 ? ('/history?page='+(page-1)) : null,
      showNext: (count > offset + 5) ? ('/history?page='+(page+1)) : null
    });
  });
});

app.get('/download/:archiveId', function(req, res) {
  var archiveId = req.param('archiveId');
  opentok.getArchive(archiveId, function(err, archive) {
    if (err) return res.send(500, 'Could not get archive '+archiveId+'. error='+err.message);
    res.redirect(archive.url);
  });

  }, function(err, archive) {
    if (err) return res.send(500,
      'Could not start archive for session '+sessionId+'. error='+err.message
    );
    res.json(archive);

// Start the express app
function init() {
  app.listen(server_port, function() {
    // console.log('You\'re app is now ready at http://localhost:3000/');
     console.log( "Listening on "  + ", server_port " + server_port )
  });
}

Answer 1

查看您的Heroku日志，似乎您绑定到端口3000而不是通过PORT环境变量提供的端口（请参阅Heroku docs）。将第4行更改为此行：

var server_port = process.env.PORT || 3000;

nodejs部署到Heroku并且openshift失败了，但是本地方面正在工作
