python采集电商jd app搜索商品数据(2023-10-30)

一、技术要点：

1、cookie可以从手机app端用charles抓包获取；

2、无需安装nodejs，纯python源码；

3、搜索接口为：functionId=search；

4、clientVersion = "10.1.4"同时也支持更高的版本；

5、sign签名算法已转成python源码；

6、body为：

uri编码后为：

7、sign签名需要的参数：

sign=service.get_st_sign_sv(data_json, functionId, uuid, clientVersion)

data_json ：即body

functionId :接口类型，即：functionId ="search"

uuid ：设备标识，可抓包取得，即：uuid="d5aada6c69ce7237"

clientVersion：app版本号，即：clientVersion = "10.1.4"
