Simple analysis of ACFUN login and fan list API

Recently, I want to update the WordPress Fantasy directory plug-in I wrote before to produce an AcFun API version.
There is no fan tracking list on the website. I used Fiddler to grab the package of AcFun APP on the Android mobile terminal. Here I record the analysis results.

previously on

The API next door (BiliBili) has official documents, while the API on the AC side seems not to be public, and no public documents can be found. I can't help but pick up the bag by myself.

The API captured here is only for learning and should not be used for commercial purposes. The infringement caused by use is irrelevant to this article.
