sho*_*a T 10 sockets proxy websocket node.js node-http-proxy
我使用以下模块,它适用于反向代理 https://github.com/nodejitsu/node-http-proxy 目前我使用的代码如下例
httpProxy.createServer({
target: 'ws://localhost:9014',
ws: true
}).listen(8014);
我的问题是如何检查/模拟 websockets是否正常工作？任何测试都会有所帮助......
为了响应OP的浏览器测试请求,我修改了原始解决方案,将HTTP和WS流量代理到服务器的服务器index.html.然后,该文件通过WebSocket将浏览器连接到代理服务器,然后代理服务器代理主服务器.从主服务器在浏览器文档上打印一条简单的消息.
所以不需要复制/粘贴任何东西,我用完整的指令创建了这个repo:https://github.com/caasjj/httpproxy.git
这是代码,以防其他人想在这里查看它.要运行整个操作,请创建两个服务器文件和index.html文件,使用node proxyreceiver.js和启动服务器,node proxyserver.js然后导航到localhost:8014/index.html.
(proxyserver.js):
var httpProxy = require('http-proxy');
var http = require('http');
var proxy = new httpProxy.createProxyServer({
target: {
host: 'localhost',
port: 9014
}
});
var proxyServer = http.createServer(function (req, res) {
proxy.web(req, res);
});
//
// Listen to the `upgrade` event and proxy the
// WebSocket requests as well.
//
proxyServer.on('upgrade', function (req, socket, head) {
proxy.ws(req, socket, head);
});
proxyServer.listen(8014);
(proxyreceiver.js):
var app = require('http').createServer(handler)
var io = require('socket.io')(app);
var fs = require('fs');
app.listen(9014);
function handler (req, res) {
res.writeHead(200);
fs.readFile('index.html', function(err, data){
res.end(data);
})
}
io.on('connection', function (socket) {
socket.emit('data', { message: 'Hello World!' });
socket.on('resp', function(msg) {
console.log('Got message: ', msg);
});
});
