使用套接字與wxpython

Question

我有一個TCP服務器和一個TCP客戶端。
我想使用wxpython製作下面的代碼的GUI版本。
我準備好了GUI界面腳本，但是，我在合併這兩個腳本時遇到了問題。

如何合併我的套接字腳本和我的GUI？

我的socket服務器

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')

Answer 1

一言以蔽之：封裝第一個腳本到一個函數。將你的函數導入wxPython應用程序。從某個事件處理函數調用該函數。將您的功能響應回傳給GUI。

但是，您需要重新設計軟件，使其不包含無限循環。事件處理程序只應該在短時間內運行。另一種方法是在一個單獨的線程中運行你的函數，通過GUI傳遞響應並添加從主GUI線程中終止線程的能力。

這些方針的東西：

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() 

然而，這並不在退出時終止另一個線程。 tcpServer.accept()正在阻止操作。你可能想看看這個answer如何以非阻塞的方式連接到套接字。然後，您將能夠輕鬆地使用某些共享標誌的終端來終止您的線程。
