在客户端上使用tkFileDialog运行服务器的文件打开对话框

Question

我正在尝试创建一个简单的系统来将文件从服务器传输到客户端。 我想使用tkFileDialog向客户端显示一个文件打开对话框。 问题是当我运行客户端＆amp;服务器对话框在服务器而不是客户端打开。我想过通过

发送tkFileDialog的对象

con.send(str(tkFileDialog.askopenfilename(initialdir='~', title='Choose a text file/program')))

如果有人可以帮我解决这个问题，那将会非常有帮助，或者如果有人有更好的想法在没有ssh的客户端中打开服务器文件系统

完整的代码是

server.py：

import socket,os
import Tkinter,tkFileDialog,tkMessageBox



def startServer(portName,ip):
    if portName != '' and ip != '':
        tkMessageBox.showinfo('Server Started','Server running!!! ok will be enabled after transfer')
        port = int(portName)
        ipName = ip
        sd = socket.socket()
        sd.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)   #reuse socket
        sd.bind((ipName, port))
        sd.listen(50)

        con, addr = sd.accept()
        print ' connection from ' + str(addr)
        con.send(tkMessageBox.showinfo('connected', 'Connection Successful'))

        while True:

            con.send(str(tkFileDialog.askopenfilename(initialdir='~', title='Choose a text file/program')))
            fileN = con.recv(1024)

            if os.path.isfile(fileN):

                con.send(tkMessageBox.showinfo('Process completed', 'Rerun server to transfer again'))
                con.send('exists')
                fileN = str(fileN)


                #read contents

                fd = open(fileN, 'r')
                buff = fd.read()
                print buff
                print len(buff)
                fd.close()

                #send contents
                con.send(str(len(buff)-1))
                print con.recv(14)    #acknowledgement of length received
                con.send(buff)
                break
            else:
                con.send(tkMessageBox.showerror('Failed', 'Select appropriate file'))

文件对话框仅适用于打开它的系统。您无法使用它来选择远程系统上的文件。
