复制代码 代码如下:
#! /usr/bin/python2.7
# — coding:utf-8 —
import os, urllib,urllib2, thread,threading
import re
#匹配音乐url
reg=re.compile(\'{\”name\”:\”(.+?)\”.+?\”rawUrl\”:\”(.+?)\”,.+?}\’, re.I)
class downloader(threading.Thread):
def __init__(self, url, name):
threading.Thread.__init__(self)
self.url=url
self.name=name
def run(self):
print \’downloading from %s\’ % self.url
urllib.urlretrieve(self.url, self.name)
threads=[]
#多线程下载文件
def main(url):
response=urllib.urlopen(url)
text=response.read()
groups=re.finditer(reg, text)
for g in groups:
name=g.group(1).strip() + \”.mp3\”
path=g.group(2).replace(\’\\\\\’, \’\’)
t=downloader(path, name)
threads.append(t)
t.start()
if __name__ == \’__main__\’:
main(\”http://site.douban.com/huazhou/\”)
for t in threads:
t.join()
