环境：
浏览器： chrome 64
python 3.6
ps：python新手，写得不好求轻喷
ps：这是更加纯净的微博内容页面
思路步骤：
打开微博移动端网址并登录，
如找到目标人物的微博，并按F12打开开发者模式，找到Network选项卡，勾选preserve log，类型选择XHR，下拉页面直至加载下一页，发现XHR中多了几项文件，打开图中的URL，如图复制响应页面的内容，并用在线json工具解析可得
设该json为r，cards=r[‘data’][‘cards’]为微博列表，对cards中的每一个card，图片信息pics_info在card[‘mblog’][‘pics’]，以此类推，获取到图片的URL之后就可以下载了
附上代码：
