巨子测肤 · 1'me — 后端服务(零依赖,Node ≥ 18)
|
||
1) 静态托管 h5/ 目录
|
||
2) POST /api/skin-analyze:三视图(正/左/右)中转 Face++ 专业版测肤
|
||
密钥只存在服务端(SKIN_API_KEY / SKIN_API_SECRET),
|
||
前端永远接触不到 api_secret。
|
||
3) 检测记录落库:data/records.jsonl(一行一条 JSON)+ data/photos/<record_id>/
|
||
原始返回仍落盘 data/results/(复核用)。后台查看页 admin.html + /api/admin/*。
|
||
启动: node server.js (默认 8080,可用 PORT 环境变量改)
