新浪微博下载相册

打开新浪微博，登录，打开yz的相册

打开chrome的开发者工具，在Sources中+New snippet

timeout=prompt("Set timeout (Second):");
count=0
current=location.href;
if(timeout>0)
setTimeout('reload()',1000*timeout);
else
location.replace(current);
function reload(){
setTimeout('reload()',1000*timeout);
count++;
console.log('每（'+timeout+'）秒自动刷新,刷新次数：'+count);
window.scrollTo(0,document.body.scrollHeight);
}

右键Run，等结束，在Elements中Copy Element body
保存为yz.txt

然后执行脚本

import os
from lxml import etree
import requests
import sys


html = etree.parse('yz.txt', etree.HTMLParser(encoding='utf-8'))
print(type(html))  # <class 'lxml.etree._ElementTree'>  返回节点树

# 查找所有 li 节点
ust = html.xpath('//ul/@group_id') #// 
print(type(ust))   # ==><class 'list'>
 
for iul in ust:
    print(iul)
    print(type(iul))
    path = str(iul)
    isExists = os.path.exists(path)
    if not isExists:
        os.makedirs(path)
    else:
        print(path)
    output = '//ul[@group_id="'
    output += str(iul)
    output += '"]//img/@src'
    print(output)
    lst = html.xpath(output)
    print(type(lst))
    for ili in lst:
        print(ili)
        link = str(ili)
        if not link.startswith('https:'):
            link = 'https:' + link
        link = link.replace("/thumb300/", "/large/")
        print(link)
        response = requests.get(link,verify=False)
        index = link.rfind('/')
        file_name = path+'/'+link[index + 1:]
        with open(file_name, "wb") as f:
            f.write(response.content)

现在只有保存图片功能，保存视频以后加吧。
