单线程.慢慢补充扩展

你要做的就是将文件路径加入到listfile列表中,哦还有,文件下载路径,这里为d:/tmp

    def __init__ (self,threadname,downfile):

        self.domainname = str(downfile.split('//')[-1]).split('/')[0]
        self.file = downfile[downfile.index(self.domainname)+len(self.domainname):]
        threading.Thread.__init__(self,name=threadname)
    def run(self):
        conn = httplib.HTTPConnection(self.domainname)
        conn.putrequest('GET',self.file)
        conn.putheader('Referer','http://'+self.domainname)
        conn.endheaders()
        rMsg = conn.getresponse()
        fwrite = open(os.path.join('d:/tmp/',self.filename),'wb+')
        print "start downloading"
        ftmp = rMsg.read(1000)
        while len(ftmp):
          fwrite.write(ftmp)
          ftmp = rMsg.read(1000)
        print "Done!\b\b\n",
        fwrite.close()
        conn.close()#建立并启动线程
listfile = [
'http://www.scriptlover.com/wish/style/spring/C0FFE51.gif',
]
for file in listfile:
  downThread = download("downThread",file)
  downThread.start()
