爬虫基本流程
抓包工具的使用
python 3.10 运行代码
pycharm 辅助敲代码
requests 第三方模块
reqable
微信客户端
一. 需求(思路)分析
找到数据的来源
https://mp.weixin.qq.com/mp/profile_ext?action=getmsg&__biz=MzkwOTI2MjM0NQ==&f=json&offset=10&count=10&is_ok=1&scene=124&uin=MjQwODIxNTMyMw==&key=f2bc285be4cea20f508e3183cf22028899478d6c6cd992a5fca68b37abbd2f67cfc36330e6207cb4d60037d436adbb8b5796a26d079539fd38b6737a5e89a3b80fb45bd3f29f86fac95f75a62c39a5fbbdc4cb92108740ab094cd297b6ad5850a8621b12b8ab3634574fe9e98ab0253c9ec79e9215f655bece9642bc78d9612f&pass_ticket=NQQv+JhXtqD/xxBpc74ykqMwmRHbEvRHPSvlKXdD9VS67OBNPGiaFD+l2QEJIhaG/ZW25Jtp7evC92qtD7tLVA==&wxtoken=&appmsg_token=1249_5DoqtKeztxPNkr0O83A6cr7n9IsXeFAjjn8zjA~~&x5=0&f=json
二. 具体代码实现
发送请求
获取数据
解析数据
非结构化数据 网页源代码
结构化数据 json数据
保存数据
导入模块
