套接字聊天应用程序无法连接

Question

我正在尝试使用套接字在Python中创建一个聊天应用程序。我无法连接（HOST，PORT）对。

这是GUI代码段，错误出现在client_socket.connect(ADDR)行中：

root = Tk()
root.title("Kchat V1.0")
mainScreenlabel = Frame(root)
mainScreenlabel.pack()
mainScreeninput = Frame(root)
mainScreeninput.pack(side=BOTTOM)
HOST = StringVar()
titleLabel = Label(mainScreenlabel, text="Welcome to Kchat!!")
inputLabel = Label(mainScreeninput, text="Host IP :")
inputEntry = Entry(mainScreeninput, textvariable=HOST)
connectButton = Button(mainScreeninput, text="Connect", command=connect)
titleLabel.pack()
inputLabel.pack(side=LEFT)
inputEntry.pack(side=LEFT)
connectButton.pack()
PORT = 33000
BUFSIZ = 1024
ADDR = (HOST, PORT)
client_socket = socket(AF_INET, SOCK_STREAM)
client_socket.connect(ADDR)

receive_thread = Thread(target=receive)
receive_thread.start()
root.mainloop() #Starts GUI execution

这是我得到的错误：

Tracebak (most recent call last):
    File".\chatClient.py", line 76, in <module>
      client_socket.connect(ADDR)

TypeError: str, bytes or bytearray expected, not StringVar

Answer 1

您可以尝试：

client_socket.connect(HOST, PORT)
