折腾：
期间，已经得到了J字段的解密逻辑，且用python脚本实现了。
接下来要继续去用Charles+Nox夜神模拟器，继续分析剩余其他所有的和绘本相关的api请求。
并且配合Postman和Python解密脚本去获取和解析返回数据。
- 自主阅读
- api
- 一共最多90个
- “J”: “{\”userId\”:\”1134723\”,\”fieldName\”:\”\”,\”fieldValue\”:\”全部类别\”,\”grades\”:\”\”,\”levels\”:\”\”,\”supportingResources\”:\”有音频\”,\”offset\”:90,\”limit\”:10}”,
- 亲子阅读
- api
- 一共最多50个
- “J”: “{\”userId\”:\”1134723\”,\”fieldName\”:\”\”,\”fieldValue\”:\”全部类别\”,\”theStageOfTheChild\”:\”\”,\”parentalEnglishLevel\”:\”\”,\”supportingResources\”:\”有音频\”,\”offset\”:50,\”limit\”:10}”,
- {“J”:”{\”userId\”:\”1134723\”,\”fieldName\”:\”\”,\”fieldValue\”:\”全部类别\”,\”theStageOfTheChild\”:\”\”,\”parentalEnglishLevel\”:\”\”,\”supportingResources\”:\”有音频\”,\”offset\”:0,\”limit\”:10}”,”C”:0}
对此，专门去Postman中测试，确保是可以返回数据的：
对于返回数据，解密后是这样的：
所以明显是:
pk=primary key=主键
然后分别对于每个book
再去调研接口

还有对应网页版，其中有公开的很多数目的信息
点击 包含图书
看起来涉及到2个请求：

后记：
此处的：
- 120.136174
- 28.997280
先后两次调试，都是一样的，没变
-》去Charles中搜
28.997280
找到：
-》推测是：
- 经度：120.136174
- 维度：28.997280
api中，填上固定的经纬度，估计就可以了。
而：
- 109512
- 是前面单个seriesBook的pk，即id
- 10
- 没找到出处
- 且去看了其他book，也是10
- 暂时就用固定值10吧
- 后记：看到源码中，还的确就是经纬度和固定的10
