From a156252bc3a4f651f5bbf455a3421ab26fae0cde Mon Sep 17 00:00:00 2001 From: Asfmq <2696428814@qq.com> Date: Mon, 6 Jul 2026 00:07:25 +0800 Subject: [PATCH]

=?UTF-8?q?=E8=B7=A8=E6=BA=90=E5=85=89=E8=B0=B1=E4=B8=8B=E8=BD=BD?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 新增天文观测数据获取能力，覆盖星表查询与一维光谱下载两大场景： 星表检索（CDS VizieR） - VizieR TAP 客户端（JSON 优先 + VOTable 降级），共享 IVOA VOTable 解析层 - 业务层支持自由 ADQL、锥形检索、交叉证认、星表发现与 CSV 导出 - ADQL 注入防护（标识符清洗 + 字符串字面量转义），TTL 缓存（7 天） 跨望远镜光谱下载（统一入口） - 接入 LAMOST（ConeSearch + FITS.gz）、Gaia（TAP + DataLink ZIP）、 SDSS（Data Lab TAP + SAS）、DESI（HEALPix coadd）四源 - 双模式：坐标模式（cone 检索 → 选源 → 下载）/ 标识符模式（直按 ID 下载） - 光谱文件永久缓存（不可变），按 source+source_id 去重 Agent 与 API - +4 工具：query_vizier / cone_search / find_spectrum / catalog_operation（22 → 26） - +6 路由：/catalog/vizier、/cone、/crossmatch、/spectrum/{download,list} - 前端新增 VizierResultCard / FindSpectrumCard 可视化卡片 工程重构 - services/target.rs (832 行) 拆分为 services/cds/{target,vizier}.rs + clients/cds/sesame.rs， 贯彻 client（通信）/ service（缓存+编排）分层 - ADS 返回字段新增 data（关联数据表 URL），与星表功能联动 --- .env.example | 5 + Cargo.lock | 139 +-
