一起执行两个无限循环。 1个多线程服务器的while循环和GUI的其他无限循环

Question

一起执行两个无限循环。 多线程服务器使用1 while循环，GUI使用其他无限循环。

GuI窗口未显示。

我试图同时执行服务器和GUI，现在没有打开GUI窗口。

下面是代码。

import socket
import sys
from thread import *

from Tkinter import *
import tkMessageBox
blue ="#000fff000"

root = Tk()
frame = Frame(root)
frame.pack()
root.geometry("500x500")
e=NONE

frame=Frame(root)
frame.pack()

text_area = Text(frame)
text_area.pack(side=BOTTOM)

B1 = Button(root, text = "CLOSE", command = sys.exit)
B1.pack(side =TOP)
print "Hello"


try:
   s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
except socket.error,msg:
   print "Socket Creation Error"
   sys.exit();


print 'Socket Created'
host = ''
port = 9008



try:
   s.bind((host, port))
except socket.error,msg:
   print "Bind Failed";
   text_area.insert(END,"Bind failed")
   sys.exit()



text_area.insert(END,"Socket bind complete")
s.listen(10)
text_area.insert(END,"Socket now listening")
a = []



def clientthread(conn):
   global text_area
   i=1024
   while True:
      data = conn.recv(1024)     
      text_area.insert(END,"\n")
      text_area.insert(END,data)
      i=i+1
      text_area.insert(END,"\n")
      reply = "Reply"+str(i)
      text_area.insert(END,reply)
      conn.send(reply)

print "hello"
print "bye"


while True:
   conn, addr = s.accept()
   start_new_thread(clientthread,(conn,))

conn.close()
s.close()

您需要为套接字服务器的主循环启动另一个线程。 这将允许主线程运行UI。

只需用以下代码替换循环：

def server_thread(s):
   while True:
      conn, addr = s.accept()
      start_new_thread(clientthread,(conn,))

start_new_thread(server_thread,(s,))
