# ==================== 平台后台 SPA 静态托管 ====================
|

# 之前 platform.yunzer.cn 的 SPA 静态文件依赖 nginx 在对应 server 块里
|
||||
# 配 location ~ ^/(platform|backend|auth|api|app)/ { proxy_pass ... } 反代到 Go,
|
||||
# 而 nginx 默认 server 块经常只有 root + static,缺这条就会让所有 API 请求 404。
|
||||
# 现在由 Go 自己吐这些 host 的 SPA 静态;/platform|/backend|/auth|/api|/app
|
||||
# 仍走 beego Router;/uploads|/themes 走 main.go 注册的 SetStaticPath。
|
||||
# 多 host 用英文逗号分隔;目录留空则关闭该功能,回落到由 nginx 自行处理。
