这些是我正在使用的节点和所需模块的版本：
- Node.js：0.10.16
- Websocket 库：einaros/ws ws@0.4.28
- 代理服务器：nodejitsu/node-http-proxy http-proxy@0.10.3
当我运行以下程序时，我的控制台输出如下所示，并且不会超出这一点：
$ node app.js
proxy: got upgrade, proxying web request
wss: got connection
这是代码：
// app.js
// A simple proxying example
//
// Setup websocket server on port 19000
// Setup proxy on port 9000 to proxy to 19000
// Make a websocket request to 9000
//
var WebSocket = require('ws'),
WebSocketServer = WebSocket.Server,
proxy = require('http-proxy');
// goes in a loop sending messages to the server as soon as
// the servers are setup
var triggerClient = function() {
var ws = new WebSocket('ws://localhost:9090/');
ws.on('open', function() {
console.log('ws: connection open');
setInterval(function() {
ws.send("Hello");
}, 1000);
});
ws.on('message', function(data) {
console.log('ws: got ' + data);
});
}
// setup websocket server and a proxy
//
var go = function() {
// setup a websocket server on port 19000
//
var wss = new WebSocketServer({ port: 19000 });
wss.on('connection', function(ws) {
console.log('wss: got connection');
ws.on('message', function(data) {
console.log('wss: got ' + data);
ws.send('wss response: ' + data);
});
});
// setup a proxy server
var server = proxy.createServer(function (req, res, proxy) {
proxy.proxyRequest(req, res, {
host: 'localhost',
port: 19000
});
});
server.on('upgrade', function (req, socket, head) {
console.log('proxy: got upgrade, proxying web request');
server.proxy.proxyWebSocketRequest(req, socket, head, {
host: 'localhost',
port: 19000
});
});
server.listen(9090, triggerClient);
};
process.nextTick(go);
当我尝试使用 hipache 时，我的问题最终开始了，然后我将事情简化为 node-http-proxy，最后简化为这段代码。
如果您将 WebSocket 客户端连接的端口从 9090 更改为 19000（从而绕过代理），事情似乎工作正常。
任何建议，指针，反馈将不胜感激。
谢谢！
