+# [201_73] 用户行为分析功能

+## 如何测试

+2026-02-05-14.24.37.280 TeXmacs] Sent user action analytics: close
+```
+
+## 2026/02/05 实现 analyticsToSendUseAction
+### what
+通过异步 HEAD 请求上报用户行为数据到 analytics 接口。
+- URL: 通过 Scheme 函数 `account-oauth2-config` 获取
+- Product: 社区版为 "mogan"，商业版为 "liiistem"
+- 异步请求，无需等待结果
+
+### 调用时机
+- 启动时: 在 C++ 层 `init_texmacs.cpp` 中调用
+- 退出时: 在 C++ 层 `tm_server.cpp` 中调用
