插件开发求助丨安卓端如何通过本地 URL 返回动态 svg

20241027 更新

经 D 大指导，给思源笔记添加了一个 api，/api/icon/getDynamicIcon，可以通过 http://127.0.0.1:6806/api/icon?color=red&lang=zh\_CN&date=2024-10-27 直接调用动态图标

见 ✨ Add internal kernel API `/api/icon` by Achuan-2 · Pull Request #12939 · siyuan-note/siyuan

需求

想参考 wolai 的动态图标：https://www.wolai.com/wolai/2tkzTE5w7invgSTqKjSwL7

在思源也开发一个动态图标插件，目的是可以直接本地生成动态图标，而不依赖网络（wolai 说不准哪天就不让非会员用这个功能了）

目前已经在 windows 端，基本上把 wolai 的动态图标都抄了一遍，具体见插件开发 idea 丨模仿 wolai 的动态日历图标 - 链滴

问题

但是目前的问题是，我在安卓上没法用，安卓不方便调试，不知道出了什么问题

我采取的方案是参考插件 taotaochen86/siyuan-plugin-jsrunner，是写了一个 http 服务器，想问问大佬们有什么办法，能解决这个问题，让各端都可以使用链接来返回动态 svg。

下面是我目前的插件代码
