Node.js 和 web-socket-js 简单客户端服务器未打开
我的 server.js 似乎是正确的。
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, "mysite.com");
console.log('Server running at mysite.com:1337/');
我的客户端的内容如下。
function init() {
// Connect to Web Socket.
// Change host/port here to your own Web Socket server.
ws = new WebSocket("ws://mysite.com:1337");
// Set event handlers.
ws.onopen = function() {
output("onopen");
};
}
如果我访问 http://www.mysite.com:1337 我会正确收到 Hello World!但是，当我尝试使用客户端连接并在 Fire bug 中进行调试时，我得到以下输出。
[WebSocket] connected
[WebSocket] request header: GET / HTTP/1.1 Upgrade: WebSocket Connection: Upgrade Host: mysite.com:1337 Origin: http://www.mysite.com Cookie: Sec-WebSocket-Key1: 115 17 p^!x-93 IERc16 7 Sec-WebSocket-Key2: 1 75 7Z i `. 8u $l031 4j9
[WebSocket] sent key3: ±Ôñ<g
[WebSocket] closed
在我有机会做任何事情之前，WebSocket 会自动关闭。谁能解释一下我收到的错误以及您认为我应该做什么？
My server.js seems to be correct..
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, "mysite.com");
console.log('Server running at mysite.com:1337/');
The meat of my client is below.
function init() {
// Connect to Web Socket.
// Change host/port here to your own Web Socket server.
ws = new WebSocket("ws://mysite.com:1337");
// Set event handlers.
ws.onopen = function() {
output("onopen");
};
}
If I go to http://www.mysite.com:1337 I correctly receive Hello World! However, when I try to connect using my client, and debug in Fire bug, I get the following output.
[WebSocket] connected
[WebSocket] request header: GET / HTTP/1.1 Upgrade: WebSocket Connection: Upgrade Host: mysite.com:1337 Origin: http://www.mysite.com Cookie: Sec-WebSocket-Key1: 115 17 p^!x-93 IERc16 7 Sec-WebSocket-Key2: 1 75 7Z i `. 8u $l031 4j9
[WebSocket] sent key3: ±Ôñ<g
[WebSocket] closed
And the WebSocket is automatically closed before I have any chance to do anything. Can anyone please shed some light on the error I am receiving and what do you think I should do?

您已经创建了一个 node.js HTTP 服务器，但您正在尝试将其作为 WebSockets 服务器连接。 WebSockets 协议不是普通的套接字，也不是普通的 HTTP 请求。 WebSocket 具有类似于 HTTP 的握手，但之后您将拥有一个全双工连接（类似于套接字，但与 HTTP 不同），该连接具有少量消息帧（与普通套接字不同）。
尝试使用 Socket.IO 或 node-websocket-server 如果你想创建一个node.js WebSockets服务器。另一方面，如果您想从 Javascript 连接到常规 HTTP 服务器，请使用具有 AJAX 支持的优秀 Javascript 库之一，例如 jQuery。
You have created a node.js HTTP server but you are trying to connect to it as a WebSockets server. The WebSockets protocol is not plain sockets and it is not plain HTTP request. WebSockets have an HTTP like handshake but after that you have a full-duplex connection (like sockets and unlike HTTP) that has a small amount of message framing (unlike plain sockets).
Try using Socket.IO or node-websocket-server if you want to create a node.js WebSockets server. On the other hand if you are wanting to connect from Javascript to a regular HTTP server then use one of the great Javascript libraries with AJAX support such as jQuery.
