目标:不再手工维护外部 nginx 配置,把"域名→内网后端、是否走统一登录认证"
变成后台可编辑的数据,由本进程生成 nginx 配置并热加载。
本提交只做基础层(纯 Go、可测、零行为变更):
- gateway.go:Route/H gatewayConfig 数据模型 + ValidateRoute + RenderGatewayConf
· 认证**按路由**决定:RequireLogin 为真才生成 auth_request 与登录跳转,
也就是"哪些服务受统一认证保护"完全由路由表决定
· 支持 websocket 透传、单域名上传上限、HTTPS 段(可同时生成旁路端口)
· 路由表单独存 gateway.yml(不混进 Dashy 的 conf.yml),写坏了也不影响导航页
- API:GET/POST /admin/api/gateway/routes(保存)、POST /admin/api/gateway/apply
· apply 的顺序是 生成 → nginx -t 校验 → 通过才 reload;**校验失败把上一份可用
配置写回去并把 nginx 原始报错回给界面**,避免"点了应用整个入口挂掉"
- nginx.conf 加 include /app/data/gateway/*.conf(生成物在容器自己的卷里,
不碰宿主机文件,天然避开"单文件 bind mount 不能用 sed -i"的坑)
- 生成物默认监听旁路端口(8081/8443):可以先与正式入口并存验证,再切 80/443
测试:受保护域名必须有 auth_request、未受保护域名必须没有;websocket/上传上限;
空域名/带协议域名/非 http 后端/域名重复/需认证却无认证地址/启用 HTTPS 却无证书
六种非法输入必须报错;缺文件时回落默认配置、保存后回读一致。
