[英]Node http proxy with proxytable and websockets
I'm trying to get websockets to also work with node-http-proxy
. 我正在尝试使websocket也可以与
node-http-proxy
。 The difference is i'm using a proxytable: 区别在于我使用的是proxytable:
var options = {
router: {
'a.websterten.com': '127.0.0.1:150',
'b.websterten.com' : '127.0.0.1:151',
}
};
var server = httpProxy.createServer(options);
I tried: 我试过了:
server.on('upgrade', function (req, socket, head) {
server.proxy.proxyWebSocketRequest(req, socket, head);
});
But it doesn't seem to work. 但这似乎不起作用。 A quick check to see whether websockets work shows I get
Unexpected response code: 400
from Chrome (works fine if I go directly) 快速查看websockets是否正常工作,显示我从Chrome收到
Unexpected response code: 400
(如果我直接去的话,效果很好)
Also doing a couple of checks server.on('upgrade',..
doesn't fire on a websocket request 也做了几次检查
server.on('upgrade',..
不会在websocket请求上触发
How can I get my proxy server to route websockets correctly? 我怎样才能使我的代理服务器正确地路由websocket?
I've also tried this on node 0.8.23 as well as node 0.10.x (the later versions of node have a memory leak issue, but it wont work on 0.8.23 either) 我也在节点0.8.23和节点0.10.x上进行了尝试(节点的更高版本存在内存泄漏问题,但也无法在0.8.23上运行)
When you use httpProxy.createServer()
, it's not necessary to handle the upgrade
event because http-proxy handles it automatically. 使用
httpProxy.createServer()
,无需处理upgrade
事件,因为http-proxy会自动处理它。 Thus, your server.on('upgrade', ...)
never fires because http-proxy is already handling it internally. 因此,您的
server.on('upgrade', ...)
永远不会触发,因为http-proxy已经在内部对其进行处理。
The only time you need to do server.on('upgrade')
is when you pass middleware functions to httpProxy.createServer
or if you've manually created the server with http.createServer()
. 唯一需要做的
server.on('upgrade')
是将中间件函数传递给httpProxy.createServer
或者使用http.createServer()
手动创建服务器时。
In other words, websockets should "just work" through the proxy in your configuration. 换句话说,websockets应该通过您配置中的代理“正常工作”。
However, WebSocket support in http-proxy is currently broken on node v0.10.x because of streams2 (the stream APIs in node core were completely rewritten in 0.10 ). 但是,由于stream2(节点核心中的流API 已完全用0.10重写 ),http-proxy中的WebSocket支持当前在节点v0.10.x上已断开 。 Also , the most recent release of http-proxy (0.10.2) is broken in node v0.8 because of a botched fix for the streams2 issue.
另外 ,由于对streams2问题的错误修复 ,最新版本的http-proxy(0.10.2)在节点v0.8中被破坏。
So you have two options: 因此,您有两种选择:
(You can install old versions of npm modules by running npm install http-proxy@0.10.1
.) (您可以通过运行
npm install http-proxy@0.10.1
来安装旧版本的npm模块。)
