我有一个套接字应用程序，我试图在端口 443 (https) 上进行监听。如果我更改端口（例如 8080），我不会遇到任何问题。

显示的错误是

error raised: Error: listen EACCES

我的应用程序源代码是：

var fs = require('fs');

// create the https server and listen on port
var options = {
    ca:   fs.readFileSync('ca.pem'),
    cert: fs.readFileSync('cert.pem'),
    key:  fs.readFileSync('server.key')
};

var server = require('https').createServer(options);
var portNo = 443;
var app = server.listen(portNo, function() {
  console.log((new Date()) + " Server is listening on port " + portNo);
});

// create the socket server on the port
var io = require('socket.io').listen(app);


// This callback function is called every time a socket
// tries to connect to the server
io.sockets.on('connection', function (socket) {

    console.log((new Date()) + ' Connection established.');

    // When a user send a SDP message
    // broadcast to all users in the room
    socket.on('message', function (message) {
        socket.broadcast.emit('message', message);
    });

    // When the user hangs up
    // broadcast bye signal to all users in the room
    socket.on('disconnect', function () {
        // close user connection
        console.log((new Date()) + " Peer disconnected.");
        socket.broadcast.emit('user disconnected');
    });
});

我已经看到很多与 Linux 相关的答案告诉他们以 sudo 身份运行，所以我尝试以管理员身份运行节点服务器，但无济于事。

这是在 Windows Server 2012 机器上运行的。

谢谢。

我想补充一点，如果您在启动节点应用程序时没有 root 权限级别，您将无法在端口 443 上运行

Have you verified that port 443 isn't already being used?

Go to your command line and run netstat -a and verify that :443 is not already in the list. If it is you'll need to terminate whatever process is using that port before proceeding.
