tsk_nuoKSM4Vt-zK ## 服务端(server/cmd/mockserver) - `main.go`(79 行):独立 mock HTTP server,实现 POST /v1/nodes/:id/connect - 路径/请求体/响应体字段名与 §3.1 契约逐字一致 - Bearer token 鉴权(-token 参数,空值跳过,不入库) - 缺少 device_id → 400;未授权 → 401;非 POST → 405 - 返回完整 sing-box config JSON(tun + REALITY/Hy2 outbound + urltest + route/dns) - 注:mock 联调;待 #5/#6 真实 connect 接口就绪后替换 - `main_test.go`:6 项单测,覆盖 §3.1 结构校验、auth、method、path ## 客户端(client/) - `lib/services/connect_api.dart`:ConnectApi 类 - fetchConfig(nodeId, deviceId) → 原始响应体字符串(不做任何修改) - 错误路径:HTTP 非 200 / 超时 / 非法 JSON → ConnectApiException(含双语 message) - `lib/services/vpn_bridge.dart`:VpnBridge stub(M6 联调,libbox 绑定待 11C) - start(configJson) 原样存储,不修改;stop() 清空 - `lib/widgets/home_shell.dart`:_toggle/_pick 替换为真实 API 流程 - ConnectApi.fetchConfig → VpnBridge.start(透传,无中间变换) - 错误路径:ConnectApiException → SnackBar,status 回 off,无残留半开隧道 - API URL/token/deviceId 由 --dart-define 注入(不入库) - `lib/widgets/server_tile.dart`:ServerInfo 新增 nodeId 字段 - `pubspec.yaml`:新增 http: ^1.2.1 依赖 - `test/connect_passthrough_test.dart`:4 项透传断言单测 - 核心:fetchConfig 返回字符串 === VpnBridge.start 接收字符串(逐字节相等) - 空格/格式原样保留(不经 jsonEncode 重序列化) - HTTP 错误、非法 JSON 错误路径覆盖 ## 运行方式(M6 联调) ``` # 启动 mock server(无 auth) go run ./server/cmd/mockserver -addr :8081 # 启动客户端(指向 mock server) flutter run \ --dart-define=PANGOLIN_API_URL=http://localhost:8081 \ --dart-define=PANGOLIN_API_TOKEN=dev-mock-token \ --dart-define=PANGOLIN_DEVICE_ID=demo-device-001 ``` Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
