我有一个 TCP 服务器和一个 TCP 客户端。
我想使用下面代码的 GUI 版本。
我已经准备好 GUI 界面脚本,但是在合并这两个脚本时遇到了问题。

如何合并我的套接字脚本和我的 GUI?

我的套接字服务器

from socket import *
from time import ctime
import random

bufsiz = 1024
port = random.randint(1025,36000)
host = 'localhost'
addr = (host, port)
print 'Port:',port

tcpServer = socket(AF_INET , SOCK_STREAM)
tcpServer.bind(addr)
tcpServer.listen(5)
try:
    while True:
        print 'Waiting for connection..'
        tcpClient, caddr = tcpServer.accept()
        print 'Connected To',caddr

        while True:
            data = tcpClient.recv(bufsiz)
            if not data:
                break
            tcpClient.send('[%s]\nData\n%s' % (ctime(),data))
            print data
        tcpClient.close()

except KeyboardInterrupt:
    tcpServer.close()

raw_input('Enter to Quit')

我的 GUI 脚本(使用 wxglade 制作)

简而言之:将您的第一个脚本封装成一个函数。将您的函数导入 wxPython 应用程序。从某个事件处理程序调用该函数。将您的函数响应传达回 GUI。

但是,您需要重新设计您的软件,使其不包含无限循环。事件处理程序应该只运行很短的时间。另一种方法是在单独的线程中运行您的函数,与 GUI 通信响应并添加从主 GUI 线程终止线程的能力。

这些方面的东西:

import wx
from socket import *
from time import ctime
import random
import threading

bufsiz = 1024
port = random.randint(1025,36000)
host = 'localhost'
addr = (host, port)

class MainWindow(wx.Frame):
    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)

        self.panel = wx.Panel(self)
        self.text = wx.TextCtrl(self.panel, style=wx.TE_MULTILINE)

        self.sizer = wx.BoxSizer()
        self.sizer.Add(self.text, 1, wx.ALL | wx.EXPAND, 5)

        self.panel.SetSizerAndFit(self.sizer)  
        self.Show()

        self.thread = threading.Thread(target=self.Server)
        self.thread.start()

    def Print(self, text):
        wx.CallAfter(self.text.AppendText, text + "\n")

    def Server(self):
        self.Print("Port: {}".format(port))

        tcpServer = socket(AF_INET , SOCK_STREAM)
        tcpServer.bind(addr)
        tcpServer.listen(5)
        try:
            while True:
                self.Print("Waiting for connection...")
                tcpClient, caddr = tcpServer.accept()
                self.Print("Connected To {}".format(caddr))

                while True:
                    data = tcpClient.recv(bufsiz)
                    if not data:
                        break
                    tcpClient.send('[%s]\nData\n%s' % (ctime(), data))
                    self.Print(data)
                tcpClient.close()

        except KeyboardInterrupt:
            tcpServer.close()

app = wx.App(False)
win = MainWindow(None)
app.MainLoop()

但是,这不会在退出时终止另一个线程。tcpServer.accept()正在阻塞操作。您可能想查看这个答案如何以非阻塞方式连接到套接字。然后,您将能够使用某些类型的共享标志轻松终止您的线程。
