socket客户端代码

利用tkinter打印出界面，在界面内设置IP端口和文件，并设置提交函数

import sys,os,time,_threadfrom socket import *from tkinter import *from tkinter.messagebox import showinfoclass Client(object):    def __init__(self):        pass    def now(self):        return time.asctime()    def client(self,host,port,filename):               #客户端运行        sock = socket(AF_INET, SOCK_STREAM)        sock.connect((host, port))        sock.send((filename + '\n').encode())        dropdir = 'New ' + os.path.split(filename)[1]  # 获取文件地址，保存在默认目录下        file = open(dropdir, 'wb')                     # 创建本地文件        while True:            data = sock.recv(1024)            if not data: break            file.write(data)                           # 储存数据        sock.close()        file.close()        print('Client got ',filename, 'at', self.now())def onSunbmit(content):                                #定义按钮的函数    host = content['Server'].get()    port = int(content['Port'].get())    filename = content['File'].get()        Client.client(Client(),host,port,filename)    showinfo('Get-File','Download complete')def main():                                            #利用tkinter设置GUI界面    box = Tk()    labels = ['Server', 'Port', 'File']    rownum = 0    content = {}    for label in labels:        Label(box, text=label).grid(column=0, row=rownum)        entry = Entry(box)        entry.grid(column=1, row=rownum, sticky=E + W)        content[label] = entry        rownum += 1    box.columnconfigure(0, weight=0)    box.columnconfigure(1, weight=1)    Button(text='Submit', command=lambda :onSunbmit(content)).grid(row=rownum,column=0,columnspan=2)    box.title('Get——File')    box.bind('
