[英]How to Complete a WebSocket Handshake in javascript(client) and java (server)?
[英]Why is Autobahn Twisted Websocket server is not completing handshake with javascript client?
我正在尝试使用扭曲的websocket服务器并将其连接到localhost上的javascript客户端,而不是通过网络。 服务器和客户端看到对方但无法完成握手。 是的,由于系统要求,我正在使用txWS提供的Hixie-76包装器。
我难以理解为什么他们无法连接?
版本:高速公路0.16,扭曲0.16.3
这是我想要实现的实际示例: https : //github.com/crossbario/autobahn-python/tree/master/examples/twisted/websocket/echo使用server.py和client.html

2016-08-24 15:44:39+0100 [-] connection was closed uncleanly (peer did not finish (in time) the opening handshake)
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()
使用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();
好的,我发现了这个问题。 正如迈克尔S所暗示的那样,它可能是在Hixie-76封装器中。 开发人员必须让协议随着时间推移而不再有效。 我可以通过在代码中追溯来确认这一点。 我将把它报告给txWS的开发者。
我找到了Hixie-76问题的替代解决方案。 我在https://github.com/gleicon/txwebsockets上将包装器切换到txWebSockets。 不是优雅的解决方案,但它现在有效。
