unknown url type: '//ww4.sinaimg.cn/mw600/661eb95cgw1fawcpuvexqj20ij0rswfo.jpg'
在url前面加上http:或者https:
'http://ww4.sinaimg.cn/mw600/661eb95cgw1fawcpuvexqj20ij0rswfo.jpg'

在url前面加上http: ...

请问在哪里加？在url里面吗
def download_mm(folder='OOXX', pages=2):
    os.mkdir(folder)
    os.chdir(folder)

    url = "http://jandan.net/ooxx/"
    page_num = int(get_page(url))

    for i in range(pages):
        page_num -= i
        page_url = url + 'page-' + str(page_num) + '#comments'
        img_addrs = find_imgs(page_url)
        save_imgs(folder, img_addrs)

if __name__ == '__main__':
    download_mm()

左手十字

获取图片地址的函数写的不对，查找字符串的时候没有加上http
