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：

{"addrFilter":"1","addressId":"0","articleEssay":"1","deviceidTail":"83","exposedCount":"0","frontExpids":"F_0_0","gcAreaId":"25,2258,2259,57314","gcLat":"24.343493","gcLng":"102.548052","imagesize":{"gridImg":"531x531","listImg":"390x390","longImg":"531x680"},"insertArticle":"1","insertScene":"1","insertedCount":"0","isCorrect":"1","keyword":keyword,"latitude":"24.343321","localNum":"0","longitude":"102.548038","newMiddleTag":"1","newVersion":"3","oneBoxMod":"1","orignalSearch":"1","orignalSelect":"1","page":page,"pageEntrance":"1","pagesize":"10","posAreaId":"25,2258,2259,57314","pvid":pvid,"searchVersionCode":"9398","secondInsedCount":"0","showShopTab":"yes","showStoreTab":"1","stock":"1"}

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"
