python实现 获取b站主播直播间 粉丝牌信息

前言

用于实现通过牌子逆向查主播信息这个功能。
插件基于Nonebot2开发，链接：https://github.com/Ikaros-521/nonebot_plugin_searchBiliInfo

gitee：https://gitee.com/ikaros-521/get_bili_medal_list

目录结构

data.py数据源自vtbs.moe
1.py用于获取数据
2.py用于中断时候的下标检索
data_medal.py用于存储用户结果数据

API

https://api.live.bilibili.com/xlive/web-room/v1/index/getInfoByUser?from=0&not_mock_enter_effect=1&room_id= 传入主播的房间号，解析json["data"]["medal"]["up_medal"]["medal_name"]，即可。

使用

安装相应的第三方库（aiohttp）后，python 1.py 即可。
