python - PyQt5 中的 WebSocket 服务器，显然是正确的，但我无法连接

Question

我需要在pyqt5中创建一个websocket服务器，阅读5.3版本的文档，其中有所有必要的类，请按照C++中的这些示例 http://doc.qt.io/qt-5/qtwebsockets-examples.html这就是结果:

from PyQt5 import QtCore, QtWebSockets,  QtNetwork

class MyServer(QtCore.QObject):
    def __init__(self,  parent=None):
        super(QtCore.QObject, self).__init__(parent)
        self.server = QtWebSockets.QWebSocketServer('My Socket', QtWebSockets.QWebSocketServer.NonSecureMode)
        if self.server.listen(QtNetwork.QHostAddress.LocalHost, 1302):
            print('Connected: '+self.server.serverName()+' : '+self.server.serverAddress().toString()+':'+str(self.server.serverPort()))
        else:
            print('error')
        self.server.newConnection.connect(self.onNewConnection)

        print(self.server.isListening())

    def onNewConnection(self):
        print(self.sender())
        print("inside")
        self.server.textMessageReceived.connect(self.processTextMessage)
        self.server.binaryMessageReceived.connect(self.processBinaryMessage)
        self.server.disconnected.connect(self.socketDisconnected)

    def processTextMessage(self,  message):
        print(message)

    def processBinaryMessage(self,  message):
        print(message)

    def socketDisconnected(self):
        print('out')

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MyServer()
    sys.exit(app.exec_())

运行 isListening 方法时，返回 true，这让我相信这段代码是正确的，但是我尝试通过 javascript 客户端(html5 websocket)进行连接，它返回一个服务器连接错误，当我尝试拍摄时也会发生同样的情况通过telnet连接服务器(telnet localhost 1302)。

感谢您的回复，代码中还有其他错误，如果有人需要，最终代码:

from PyQt5 import QtCore, QtWebSockets,  QtNetwork, QtWidgets

class MyServer(QtCore.QObject):
    def __init__(self, parent):
        super(QtCore.QObject, self).__init__(parent)
        self.clients = []
        self.server = QtWebSockets.QWebSocketServer(parent.serverName(), parent.secureMode(), parent)
        if self.server.listen(QtNetwork.QHostAddress.LocalHost, 1302):
            print('Connected: '+self.server.serverName()+' : '+self.server.serverAddress().toString()+':'+str(self.server.serverPort()))
        else:
            print('error')
        self.server.newConnection.connect(self.onNewConnection)

        print(self.server.isListening())

    def onNewConnection(self):
        self.clientConnection = self.server.nextPendingConnection()
        self.clientConnection.textMessageReceived.connect(self.processTextMessage)

        self.clientConnection.binaryMessageReceived.connect(self.processBinaryMessage)
        self.clientConnection.disconnected.connect(self.socketDisconnected)

        self.clients.append(self.clientConnection)

    def processTextMessage(self,  message):
        if (self.clientConnection):
            self.clientConnection.sendTextMessage(message)

    def processBinaryMessage(self,  message):
        if (self.clientConnection):
            self.clientConnection.sendBinaryMessage(message)

    def socketDisconnected(self):
        if (self.clientConnection):
            self.clients.remove(self.clientConnection)
            self.clientConnection.deleteLater()


if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    serverObject = QtWebSockets.QWebSocketServer('My Socket', QtWebSockets.QWebSocketServer.NonSecureMode)
    server = MyServer(serverObject)
    serverObject.closed.connect(app.quit)
    app.exec_()
