在openshift中运行时python websocket失败 [英] python websocket failure when run in openshift

问题描述

我有一个在python中运行的高速公路扭曲的websocket，该websocket在dev vm中正常运行，但是当服务器在openshift中运行时，我无法正常工作.

I have a autobahn twisted websocket running in python which is working in a dev vm correctly but I have been unable to get working when the server is running in openshift.

这是在虚拟机中对我有用的简化代码.

Here is the shortened code which works for me in a vm.

from autobahn.twisted.websocket import WebSocketServerProtocol, WebSocketServerFactory, listenWS
from autobahn.twisted.resource import WebSocketResource

class MyServerProtocol(WebSocketServerProtocol):
    def onConnect(self, request):
        stuff...
    def onOpen(self):
        stuff...
    def onMessage(self,payload):
        stuff...


factory = WebSocketServerFactory(u"ws://0.0.0.0:8080")
factory.protocol = MyServerProtocol
resource = WebSocketResource(factory)

root = File(".")
root.putChild(b"ws", resource)
site = Site(root)

reactor.listenTCP(8080, site)
reactor.run()

客户端的连接部分如下:

The connection part of the client is as follows:

var wsuri;
var hostname = window.document.location.hostname;
wsuri = "ws://" + hostname + ":8080/ws";

if ("WebSocket" in window) {
    sock = new WebSocket(wsuri);
} else if ("MozWebSocket" in window) {
    sock = new MozWebSocket(wsuri);
} else {
    log("Browser does not support WebSocket!");
    window.location = "http://autobahn.ws/unsupportedbrowser";
}

openshift配置如下:

The openshift configuration is as follows:

1个运行app.py的Pod在端口8080上侦听 未启用tls 我有一条非tls航线8080> 8080.

1 pod running with app.py listening on port 8080 tls not enabled I have a non-tls route 8080 > 8080.

Firefox在控制台中显示以下消息:

Firefox gives the following message in the console:

Firefox can’t establish a connection to the server at ws://openshiftprovidedurl.net:8080/ws.

当我使用wscat连接到Websocket时.

when I use wscat to connect to the websocket.

wscat -c ws://openshiftprovidedurl.net/ws

我收到以下错误:

error: Error: unexpected server response (400)

和openshift中的应用程序日志显示以下内容:

and the application log in openshift shows the following:

2018-04-03 01:14:24+0000 [-] failing WebSocket opening handshake ('missing port in HTTP Host header 'openshiftprovidedurl.net' and server runs on non-standard port 8080 (wss = False)')
2018-04-03 01:14:24+0000 [-] dropping connection to peer tcp4:173.21.2.1:38940 with abort=False: missing port in HTTP Host header 'openshiftprovidedurl.net' and server runs on non-standard port 8080 (wss = False)
2018-04-03 01:14:24+0000 [-] WebSocket connection closed: connection was closed uncleanly (missing port in HTTP Host header 'openshiftprovidedurl.net' and server runs on non-standard port 8080 (wss = False))

任何帮助将不胜感激！

推荐答案

Graham Dumpleton碰到了头，我修改了

Graham Dumpleton hit the nail on the head, I modified the code from

factory = WebSocketServerFactory(u"ws://0.0.0.0:8080")

到

factory = WebSocketServerFactory(u"ws://0.0.0.0:8080", externalPort=80)

，它更正了该问题.我必须修改索引以指向正确的websocket，但现在可以连接了.

and it corrected the issue. I had to modify my index to point to the correct websocket but I am now able to connect.

谢谢！
