国内 IP/域名直连(不走隧道)→ 省流量 + 国内访问快;非国内走代理。
- clientconfig.go: BuildClientConfig 加 ClientConfigOpts{SplitCN,RulesBaseURL};
开启时 route 加 {rule_set:[geoip-cn,geosite-cn]→direct} + 定义 rule_set
(remote .srs,download_detour:direct 直连下载)
- rules.go: 控制面静态服务 /v1/rules/{name}.srs(白名单防穿越)——自托管避免
GitHub 在国内被墙的鸡生蛋;客户端反正连控制面,可达性有保证
- nodes.go ConnectNode: 读 ?split_cn → opts;NodeAPI 加 rulesBaseURL
(PANGOLIN_PUBLIC_URL);main.go 挂 /v1/rules 路由 + RulesHandler
- 客户端: connect_api splitCN→?split_cn=1;connection_provider 传 smartRoute 偏好
- deploy/single-node: 拉 geoip-cn/geosite-cn.srs 到 $DATA_DIR/rules +
设 PANGOLIN_PUBLIC_URL/PANGOLIN_RULES_DIR
验证:go test(splitCN 开/关渲染 + RulesHandler 白名单/404)+ flutter analyze +
shellcheck;不需要节点。订阅链接暂用默认 opts、DNS 分流为后续增强。
