尝试使用套接字和tkinter制作服务器应用程序

Question

我正在尝试制作这个Socket&tkinter-server应用程序简而言之，这是一个tk窗口，它基本上使套接字服务器具有一些Buttons和一些Entrys。问题是服务器制造商没有工作。这就是我在填写参赛作品和按下"；创建服务器"；按钮，我应该得到一个print("Server Made!")，但我得到的却是Python is not responding哇，这些不是最好的词吗？我只是开玩笑。

这是我的代码/脚本：

from tkinter import *
from win32api import GetSystemMetrics
import time
import socket




def Client(ip,port,Cname):
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect((str(ip), int(port)))
msg = client.recv(4096)
print(msg.decode("utf-8"))


#Server Dashboard
def __main__SD():
tk = Tk()
tk.attributes('-fullscreen',True)

tk.title('SECL-Dashboard')

x = int(GetSystemMetrics(0))
y = int(GetSystemMetrics(1))


Top_Frame = Frame(width=x,height=50,bg='orange')
Top_Frame.place(x=0,y=0)

X_Button = Button(tk,width=5,height=1,text='X',bg='red',fg='white',command=tk.destroy)
X_Button.place(x=1500,y=2)

X_Button.config(font =("Bold", 16))


tk.mainloop()

print("Exiting")





# Config-CLIENT
def CONFIG2():
root = Tk()
root.resizable(width=False, height=False)

root.title("SECL-Client")
root.geometry('400x500')
x = Frame(height = 60,width = 600,bg='green')
x.pack()

TITLE = Label(root,text = "SECL",bg='green',fg='white')
TITLE.place(x=140,y=4)
TITLE.config(font =("Bold", 30))

TP = Label(root,text='Client',bg='green',fg='white')
TP.place(x=252,y=30)
TP.config(font=("Bold",15))

#Create Button

root.mainloop()


CONFIG1()

没有错误。没什么，但我只是得到了Python is not responding有没有一种方法可以修复或更好地从我的脚本中删除这个错误？顺便说一句，我正在运行windows7。

由于serv.accept()是一个阻塞函数，它将阻止tkinter-mainloop处理事件。

您需要在一个子线程中运行ALL_POINT()：

import threading
...
def CONFIG1():
...
server_running = False
# sample client handler
def handle_client(conn, addr):
conn.send(bytes(f"Welcome to {name.get()}!",'utf-8'))
while True:
data = conn.recv(512).decode().strip()
print(data)
if data == 'quit':
break
conn.close()
def ALL_POINT():
nonlocal server_running
serv = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
hostname = socket.gethostname()
ip = socket.gethostbyname(hostname)
print(ip, port.get())
serv.bind((str(ip), int(port.get())))
serv.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
serv.listen(int(mclient.get()))

print("Server: Running")
server_running = True
while server_running:
print('waiting connection ...')
conn, addr = serv.accept()
print('client connected', addr)
# run client handler in thread so that server can serve new connection
threading.Thread(target=handle_client, args=(conn, addr), daemon=True).start()
def start_server():
# make sure only one server task is active
if not server_running:
threading.Thread(target=ALL_POINT, daemon=True).start()
CreateB = Button(root, width=12, height=2, text='Create Server',
bg='#00FF00', command=start_server)
