使用PyQt5的TCP客户端线程

Question

我正在尝试在PyQ5中使用QThread创建TCP线程。这是我的代码。我有3个线路来读取IP，端口和缓冲区大小。

#!/usr/bin/env python3

# vim:fileencoding=utf-8

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from TTP_Monitor_GUI import Ui_MainWindow

import socket
import sys

class WorkerObject(QObject):

    @pyqtSlot(str, int, int)
    def ListenTCP(self, TCP_IP, TCP_PORT,BUFFER_SIZE):
        # create a socket object
        self.s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

        # Bind the socket to the port
        server_address = (TCP_IP, TCP_PORT)
        #print(server_address)
        self.s.connect(server_address)

        # Look for the response
        while True:
            self.data = self.s.recv(BUFFER_SIZE)
            #amount_received += len(self.data)
            print(self.data)

    @pyqtSlot()
    def StopTCP(self):
        print("STOP_TCP")
        print(self.data)
        self.s.close()
        print(self.data)

class Main(QMainWindow):

    SignalTCPStart = pyqtSignal()
    SignalTCPStop = pyqtSignal()

    def __init__(self, parent=None):
        super(QMainWindow, self).__init__(parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

        self.worker = WorkerObject()
        self.thread = QThread()
        self.worker.moveToThread(self.thread)

        self.ui.btnConnect.clicked.connect(self.ConnectToTCP)
        self.ui.btnDisconnect.clicked.connect(self.Disconnect)

    def ConnectToTCP(self):

        # set IP and Port
        TCP_IP = self.ui.txtIP.text()
        TCP_PORT = int(self.ui.txtPort.text())
        BUFFER_SIZE = int(self.ui.txtBuffer.text())

        self.SignalTCPStart.connect(self.worker.ListenTCP(TCP_IP, TCP_PORT,BUFFER_SIZE))

        # No harm in calling thread.start() after the thread is already started.
        self.thread.start()
        self.SignalTCPStart.emit()

    def Disconnect(self):
        self.SignalTCPStop.connect(self.worker.StopTCP)
        self.SignalTCPStop.emit()

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    myapp = Main()
    myapp.show()
    sys.exit(app.exec_())

我收到此错误：

Traceback (most recent call last):
  File "C:\Software\TTP_Monitor\TTP_Monitor.py", line 65, in ConnectToTCP
    self.SignalTCPStart.connect(self.worker.ListenTCP(TCP_IP, TCP_PORT,BUFFER_SIZE))
TypeError: argument 1 has unexpected type 'NoneType'

有趣的是，没有UI和QThread，while循环完美无缺。我可以读取数据，但上面的代码会出现此错误。

期待您的回复。
