PythonTkinter接收插座不接收

Question

我试图用pythonttkinter制作一个聊天程序，但是我的recv函数recvMSG（）要么没有接收到任何东西，要么就是不打印任何东西。在

你能帮我解决接收问题吗？你想怎么改就怎么改。在

我没有easygui，所以我删除了一些代码

from Tkinter import *
#import easygui
import socket
#import threading

msgscount = 1

setup = False
buffsize = 1024

def makeServer():
    global tcpclisock,setup,buffsize
    host = ''
    port = 9000
    buffsize = 1024
    addr = (host, port)
    setup = True

    print "makeServer():"

    tcpsersock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcpsersock.bind(addr)
    tcpsersock.listen(5)
    tcpclisock, addr = tcpsersock.accept()
    tcpclisock.setblocking(0)
    print 'Connected from: ', addr
    top.after(1000, recvMSG)

def connectServer():
    global tcpclisock,setup,buffsize
    setup = True
    host = ''
    port = 9000
    buffsize = 1024
    addr = (host, port)

    tcpclisock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcpclisock.connect(addr)
    print 'Connected to: ', addr
    tcpclisock.setblocking(0)
    top.after(1000, recvMSG)

def sendMSG():
    print 'sendMSG():'
    global msgscount, tcpclisock,setup
    try:
        msgs.insert(msgscount, ">>" + msg.get())
        data = msg.get()
        msg.delete(0,END)
        msgscount += 1
        print tcpclisock.send(data)
    except:
        print 'You need to connect to a server.'


def recvMSG():
    global msgscount,tcpclisock,setup,buffsize
    print 'recvMSG():', setup
    if setup == True:
        try:
            datar = tcpclisock.recv(buffsize)
            msgs.insert(msgscount, datar)
            msgscount += 1
        except:
            pass
        top.after(1000, recvMSG)
    else:
        pass
        answ = "Create"
        if answ == "Create":
            makeServer()
        else:
            connectServer()


top = Tk()
#top.geometry('640x650')

msgs = Listbox(top, width=105, height=43)
msgs.pack()

msg = Entry(top, bd=2, width=60, font='Arial 12 bold')
msg.pack()

sendbtn = Button(top, text='Send', font='Arial 15 bold', width=15, padx=5, pady=5, command=sendMSG)
sendbtn.pack()

menubar = Menu(top)
servermenu = Menu(menubar, tearoff=0)
servermenu.add_command(label="Create Server", command=makeServer)
servermenu.add_command(label="Join Server", command=connectServer)

top.config(menu=menubar)

mainloop()
