Question

当我尝试在heroku应用这个简单的节点应用程序时，我收到错误：

no port or path provided

这是应用程序：

server.js

var express = require("express");
var app = express();
app.use(express.logger());

app.get('/', function(request, response) {
  response.send('Hello World!');
});

var port = process.env.PORT || 5000;
app.listen(port, function() {
  console.log("Listening on " + port);
});

var dnode = require('dnode');
var server = dnode({
    zing : function (n, cb) { cb(n * 100) }
});
server.listen(app);

这是浏览器index.html

<html>
<head>
    <script src="/dnode.js" type="text/javascript"></script>
    <script type="text/javascript">
        window.onload = function () {

            DNode.connect(function (remote) {
                remote.zing(66, function (n) {
                    document.getElementById('result').innerHTML = n;
                });
            });

        };
    </script>
</head>
<body>

n = <span id="result">?</span>

</body>
</html>

然后，heroku记录：

我有什么遗漏吗？

Answer 1

您使用的是旧版api（＆lt; 1）。新版本只是一个流。查看当前自述文件，了解如何pipe everything together with the new api。

heroku支持dnode吗？
