我無法將GUI插入到我的python程序中

Question

我確定這是一個簡單的修復，但我只是在我的基礎上分開。 我需要合並一個簡單彈出的Gui，並聲明客戶端和服務器之間已建立連接。

我可以使用我的所有變量在我的代碼之上彈出GUI但它不會在我的代碼下面運行，這是我需要它顯示的連接的定義。

# it will run but (address) is not defined yet
import socket
from tkinter import *

root = Tk()
theLabel = Label(root,text="Connection from {address} has been established.")
theLabel.pack()
root.mainloop()

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((socket.gethostname(), 1234))
s.listen(5)

while True:
  clientsocket, address = s.accept()
  print(f"Connection from {address} has been established.")
  clientsocket.send(bytes("HELL YEAH FAM!!! WE DID IT!!","utf-8"))
  clientsocket.close()

它沒有錯誤消息，它只是不會運行GUI。

您必須配置所有內容，然后您可以為連接調用函數，然后在最后調用root.mainloop（）。 以下是您需要完成的一些工作：

from socket import AF_INET, SOCK_STREAM, socket, gethostname
from tkinter import *
from tkinter import ttk

IP = gethostname() # or "127.0.0.1"
PORT = 1337

root = Tk()
root.title("")
mainframe = ttk.Frame(root, padding="3 3 12 12")
mainframe.grid(column=0, row=0, sticky=(N, W, E, S))
root.columnconfigure(0, weight=1)
root.rowconfigure(0, weight=1)

for child in mainframe.winfo_children(): 
child.grid_configure(padx=5, pady=5)

root.bind('<Return>', connectionFunc)

def connectionFunc(*args):
    # this way you dont have to close the socket.
    with socket(AF_INET, SOCK_STREAM) as s:
        s.listen()
        s.bind((IP, PORT))
        conn, addr = s.accept()
        with conn:
            print(f"connection from: {addr}")
            while True:
                data = conn.recv(1024)
                if not data:
                    break
                conn.sendall(data)

root.mainloop()

你應該使用線程來等待連接：

import socket
import threading
from tkinter import *

def wait_connection():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind((socket.gethostname(), 1234))
    s.listen(5)

    while True:
        clientsocket, address = s.accept()
        msg.set(f"Connection from {address} has been established.")
        clientsocket.send(bytes("HELL YEAH FAM!!! WE DID IT!!","utf-8"))
        clientsocket.close()

root = Tk()
msg = StringVar(value='Waiting for connection ...')
theLabel = Label(root,textvariable=msg)
theLabel.pack()

# start a thread for waiting client connection
threading.Thread(target=wait_connection, daemon=True).start()

root.mainloop()
