SNKRS API变量解析

引言

  想做这个项目的原因是因为之前买的snkrs bot附带的Discord监控到期了，不能再提供各种球鞋上新监控。刚好有朋友在做球鞋定制和公众号，未来是希望把Discord和微信小程序集成在公众号下。第一步选择先做Discord端，考虑到Discord只要把后端和Discord Bot完成就行，刚好也能先熟悉一下Nike这个接口返回的各种信息。但是Discord因为某些原因被墙了，中国的开发者很少，花了很多时间研究国外开发者写的文档，进度还是比较理想的。希望暑假后能尽快开始微信小程序的开发，这才是重点！

SNKRS API

https://api.nike.com/snkrs/content/v1/?country=CN&language=zh-Hans&orderBy=lastUpdated&offset=0
URL其实比较容易拿到，用Wireshark对手机访问SNKRS APP时进行抓包操作就可以。当offset=0时，API会返回第1-50双球鞋的数据，offset=50时，API会返回第51-100双球鞋的数据，以此类推。通过totalRecords可以看到中国区SNKRS上一共有1468双球鞋。

变量解析

country: CN 中国区
totalRecords: 1468 SNKRS APP中记录总量
threads: 球鞋的所有信息，一个很长的list，中间存储的是dict。
以第一双鞋为例：
Fig.1AJ13
是一双AJ13，这双鞋在threads中的dict中有一些重要的信息：

  1. id
    API中标记一双球鞋的编号，主键
  2. name
    球鞋名称
  3. restricted
    是否受限，有些新球鞋是锁住的
  4. imageUrl
    球鞋图片，Discord中推送会用到
  5. selectionEngine
    LEO和DAN，2分钟和15分钟抽签模式，现在已经没有先到先得的FLOW模式了
  6. skus
