我有一个应用程序,通过iisnode到webs.js / Express / Socket.io应用程序的websockets非常好。
Windows Server 2012
iisnode 2.21
IIS 8.5
节点6.2.1
socket.io 1.4.8
express.js 4.14
然而,在通过HTTPS访问时,WebSockets在看似成功的 wss协商后回归到轮询:
GET wss://x.com/socket/a145e1f7-c8e7-4b26-96d3-a4d9869b5f3a/?id=a145e1f7-c8e7-4b26-96d3-a4d9869b5f3a&EIO=3&transport=websocket&sid=2nKT2dHWKrmO5xaHAAAM HTTP/1.1

但是这个WebSocket中没有框架,Socket.io返回HTTP轮询。如果由IIS处理TLS,那么在wss协议协商之后如何影响WebSockets?
答案 0 :(得分:0)
事实证明,存在导致此问题的负载均衡器问题,技术软件堆栈没有出错。
