我试图使用扭曲的websocket服务器,并将其连接到本地主机上的JavaScript客户端,而不是通过网络。服务器和客户端可以看到对方,但他们无法完成握手。是的,由于系统要求,我使用txWS提供的Hixie-76封装。为什么Autobahn Twisted Websocket服务器没有完成与javascript客户端的握手?

我难以理解为什么他们不能连接?

版本:高速公路0.16,扭曲0.16.3

这是我想要实现一个实际的例子: https://github.com/crossbario/autobahn-python/tree/master/examples/twisted/websocket/echo使用server.py和client.html

Python类:

from txws import WebSocketFactory 
from twisted.internet import reactor 
from twisted.python import log 
from autobahn.twisted.websocket import WebSocketServerFactory 
from autobahn.twisted.websocket import WebSocketServerProtocol 

import json 
import sys 

class MyServerProtocol(WebSocketServerProtocol): 

    def onMessage(self, payload, isBinary): 
     print "Message Received!!!!" 
     msg = json.dumps({'status':'PLEASE WORK'}) 
     self.sendMessage(msg, isBinary=False) 

    def onClose(self, wasClean, code, reason): 
     print "WebSocket connection closed: " 
     print str(wasClean) 
     print str(code) 
     print str(reason) 

def make_server(): 
    print 'Making ws server' 
    log.startLogging(sys.stdout) 
    factory = WebSocketServerFactory("ws://127.0.0.1:8080") 
    factory.protocol = MyServerProtocol 
    reactor.listenTCP(8080, WebSocketFactory(factory)) #txWS WebSocketFactory wrapper 
    reactor.run() 

Javascript:

function ConnectWebSocket() { 
    websocket = new WebSocket('ws://127.0.0.1:8080'); 
    websocket_open = true; 

    websocket.onopen = function(e) { 
     console.log('opened'); 
     console.log(e); 
     websocket.send('slow test'); 
    }; 
    websocket.onclose = function(e) { 
     console.log("Connection closed."); 
     websocket_open = false; 
     websocket = null; 
     ConnectWebSocket(); 
    }; 
    websocket.onmessage = function(e) { 
     console.log('message'); 
     console.log(e.data); 
    }; 
    websocket.onerror = function(e) { 
     console.log('error'); 
     console.log(e); 
    }; 
} 
ConnectWebSocket();

我可以看到的唯一的问题可能是一个问题是“u”在'(u“ws://127.0.0.1:8080”)中缺失''这只是将该字符串标记为unicode,并且从我的理解通常不是什么大不了的事情。我从来没有使用Hixie-76封装,所以我猜'WebSocketFactory(工厂)'是问题出在哪里,因为其他东西看起来都不错。 –

好吧,我发现了这个问题。正如迈克尔S所说,它可能在Hixie-76包装纸上,就是这样。开发人员必须让该协议随时间推移而失效,并且不再有效。我可以通过在代码中追溯来确认这一点。我会将其报告给txWS的开发者。

我找到了Hixie-76问题的备用解决方案。我将包装器切换到https://github.com/gleicon/txwebsockets的txWebSockets。不是一个优雅的解决方案,但它现在的作品。
