AutobahnPython w/Twisted：websocket.WampWebSocketClientFactory 上的 ssl.optionsForClientTLS答案

【问题标题】：AutobahnPython w/Twisted: ssl.optionsForClientTLS on websocket.WampWebSocketClientFactoryAutobahnPython w/Twisted：websocket.WampWebSocketClientFactory 上的 ssl.optionsForClientTLS
【发布时间】：2015-08-09 03:26:25
【问题描述】：

我无法使用“applicationRunner”，因为它不支持 websockets 的自动重新连接（GitHub 问题：#295 #389）。我已经恢复到使用扭曲的“ReconnectingClientFactory”的已弃用方法。我的问题是这种方法似乎不允许我添加“ssl.optionsForClientTLS”来严格验证服务器主机名和证书。有没有办法做到这一点？

非常感谢任何反馈！

class MyClientFactory(websocket.WampWebSocketClientFactory, ReconnectingClientFactory):
    maxDelay = config.maxretry

    def clientConnectionFailed(self, connector, reason):
        logging.debug("Connection Failed: %s", reason)
        ReconnectingClientFactory.clientConnectionFailed(self, connector, reason)

    def clientConnectionLost(self, connector, reason):
        logging.debug("Connection Lost: %s", reason)
        ReconnectingClientFactory.clientConnectionLost(self, connector, reason)

def start():
    log.startLogging(sys.stdout)

    component_config = types.ComponentConfig()
    session_factory = wamp.ApplicationSessionFactory(config=component_config)
    session_factory.session = MyFrontendComponent

    transport_factory = MyClientFactory(session_factory, 'wss://services:8443/ws', debug=True)

    transport_factory.debug = True
    transport_factory.debugCodePaths = True

    websocket.connectWS(transport_factory)

    Thread(target=reactor.run, args=(False,)).start()

没关系，想通了...希望这可以帮助其他面临同样问题的人。原来“connectWS”接受带有“optionsForClientTLS”的“contextFactory”。现在我们有了一个具有严格证书验证的自动重新连接 WebSocket：

    class MyClientFactory(websocket.WampWebSocketClientFactory, ReconnectingClientFactory):
    maxDelay = 30

    def clientConnectionFailed(self, connector, reason):
        logging.debug("Connection Failed: %s", reason)
        self.retry(connector)

    def clientConnectionLost(self, connector, reason):
        logging.debug("Connection Lost: %s", reason)
        self.retry(connector)


def start():
    log.startLogging(sys.stdout)

    component_config = types.ComponentConfig()
    session_factory = wamp.ApplicationSessionFactory(config=component_config)
    session_factory.session = MyFrontendComponent

    transport_factory = MyClientFactory(session_factory, 'wss://services:8443/ws', debug=True)

    transport_factory.debug = True
    transport_factory.debugCodePaths = True

    context_factory = None

    if transport_factory.isSecure:
        certData = getModule(__name__).filePath.sibling('server_cert.pem').getContent()
        authority = ssl.Certificate.loadPEM(certData)
        context_factory = ssl.optionsForClientTLS(u'services', authority)

    websocket.connectWS(transport_factory, context_factory)

    Thread(target=reactor.run, args=(False,)).start()
