HTML5从一个html页面打开两个web套接字

Question

我可以从一个html页面打开两个WebSocket连接到一个服务器，但两个不同的端口吗?

我在谷歌上搜索过，但找不到任何有用的东西。你还能给我一些web sockets教程的链接吗?这些是我找到的:

Answer 1

这样不行吗?

var socket1 = new WebSocket('ws://localhost:1001');
var socket2 = new WebSocket('ws://localhost:1002');

至于你的服务器如何处理它，这在很大程度上取决于你的服务器端技术。

对于教程来说，WebSockets的客户端方面非常简单，这几乎就是它了:

var socket;
// Firefox uses a vendor prefix
if (typeof(MozWebSocket) != 'undefined') {
    socket = new MozWebSocket('ws://localhost');
}
else if (typeof(WebSocket) != 'undefined') {
    socket = new WebSocket('ws://localhost');
}
if (socket != null) {
    socket.onmessage = function(event) {
        // fired when a message is received from the server
        alert(event.data);
    };
    socket.onclose = function() {
        // fired when the socket gets closed
    };
    socket.onerror = function(event) {
        // fired when there's been a socket error
    };
    socket.onopen = function() {
        // fired when a socket connection is established with the server,
        // Note: we can now send messages at this point
        // sending a simple string to the server
        socket.send('Hello world');
        // sending a more complex object to the server
        var command = {
            action: 'Message',
            time: new Date().toString(),
            message: 'Hello world'
        };
        socket.send(JSON.stringify(command));
    };
}
else {
    alert('WebSockets are not supported by your browser');
}

如何处理传入WebSocket连接的服务器端方面要复杂得多，并且取决于您的服务器端技术(ASP. js)。. NET, PHP, Node.js等)
