Python 使用线程和扭曲的sendMessage的高速公路

通过这个线程（）我试图让下面的代码正常工作

但我得到了以下错误：

  File "/usr/local/lib/python2.7/dist-packages/autobahn/websocket/protocol.py", line 2421, in sendMessage
    assert(type(payload) == bytes)
exceptions.AssertionError: 

谁能告诉我哪里出了问题

from autobahn.twisted.websocket import WebSocketServerProtocol, WebSocketServerFactory

import threading
from twisted.python import log
from twisted.internet import reactor
import sys
import time

class MyServerProtocol(WebSocketServerProtocol):

    def onConnect(self, request):
        print("Client connecting: {0}".format(request.peer))

    def onOpen(self):
        print("WebSocket connection open.")

    def onMessage(self, payload, isBinary):
        if isBinary:
            print("Binary message received: {0} bytes".format(len(payload)))
        else:
            print("Text message received: {0}".format(payload.decode('utf8')))

        # echo back message verbatim
        self.sendMessage(payload, isBinary)

    def onClose(self, wasClean, code, reason):
        print("WebSocket connection closed: {0}".format(reason))


class Connection(threading.Thread):
    def __init__(self):
        super(Connection, self).__init__()
        self.factory=WebSocketServerFactory("ws://localhost:9000", debug=False)
    def run(self):
        log.startLogging(sys.stdout)
        self.factory.protocol = MyServerProtocol()
        reactor.listenTCP(9000, self.factory)
        reactor.run(installSignalHandlers=0)

    def send(self, data):

        data = format(data.encode('utf8'))
        protocol = MyServerProtocol()
        reactor.callFromThread(protocol.sendMessage, protocol, data) 


connection = Connection()
connection.daemon = True
connection.start()
print "Running"

for x in range(1, 100):

    connection.send("hello")
    time.sleep(2)

谢谢

完全错误：

在twisted中不能这样开始线程

from autobahn.twisted.websocket import WebSocketServerProtocol, WebSocketServerFactory

from twisted.python import log
from twisted.internet import reactor
import sys

class MyServerProtocol(WebSocketServerProtocol):

    def onConnect(self, request):
        print("Client connecting: {0}".format(request.peer))

    def onOpen(self):
        print("WebSocket connection open.")

    def onMessage(self, payload, isBinary):
        if isBinary:
            print("Binary message received: {0} bytes".format(len(payload)))
        else:
            print("Text message received: {0}".format(payload.decode('utf8')))

        # echo back message verbatim
        self.sendMessage(payload, isBinary)

    def onClose(self, wasClean, code, reason):
        print("WebSocket connection closed: {0}".format(reason))

    def send(self, data):

        data = format(data.encode('utf8'))
        protocol = MyServerProtocol()
        reactor.callFromThread(protocol.sendMessage, protocol, data) 

class Test(MyServerProtocol):

    def __init__(self):
        self.factory=WebSocketServerFactory("ws://localhost:9000", debug=False)
        log.startLogging(sys.stdout)
        self.factory.protocol = MyServerProtocol
        reactor.listenTCP(9000, self.factory)
        reactor.run(installSignalHandlers=0)


Test = Test()


print "Running"

反应器必须在主线程中启动，要在twisted中使用thread，您必须使用twisted threading模块，但为什么要使用thread？这解释了我试图做的事情：如果是向twisted发送消息的外部应用程序，那么为什么要使用类连接（threading.thread）：在主线程和时间中直接使用reactor。sleep（）无法应用。使用您的代码我制作了一个没有线程的新版本，但进程永远无法到达：Test.send（“hello”）您正在创建一个服务器，因此无法向尚不存在的客户端发送消息，因此请删除Test.send（“hello”）
