response = urllib.request.urlopen(request)

buf = response.read()

buf = str(buf, encoding='utf-8')

# 获取所有图片url地址列表

listurl = re.findall(r'http.+\.jpg', buf)

print(listurl)

i = 1

for url in listurl:

    with open(str(i)+'.jpg','wb+') as f:

        req = urllib.request.urlopen(url)

        f.write(buf)

        i += 1
