From 1079e22699f39fec3f1378c4e7b37bd62c0e728c Mon Sep 17 00:00:00 2001 From: cfy666 <3087823110@qq.com> Date: Sun, 21 Jun 2026 15:38:28 +0800 Subject: [PATCH] =?UTF-8?q?feat:=20=E5=AE=9E=E7=8E=B0=E8=87=AA=E5=BB=BA?= =?UTF-8?q?=E6=83=85=E6=99=AF=E5=8A=9F=E8=83=BD?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 功能概述 - 用户可创建、编辑、删除自定义情景 - 支持自定义情景名称、图标、描述、Prompt、首句引导 - 完整的权限隔离，用户只能管理自己的情景 - 深度集成 Eino 框架，动态加载自建情景 Prompt ## 后端实现 ### 数据库 - 新增 user_scenarios 表 - 支持用户配额（最多 20 个） - 字段验证：description 可选，prompt 最小 10 字符 ### API - GET /api/scenarios - 获取用户情景列表 - POST /api/scenarios - 创建情景 - GET /api/scenarios/:id - 获取详情 - PATCH /api/scenarios/:id - 更新情景 - DELETE /api/scenarios/:id - 删除情景 ### Eino 集成 - PipelineState 添加 UserID 字段 - nodes_history 动态加载用户自建情景 - GetScenarioPrompt 支持自建情景优先级 ## 前端实现 ### 组件 - CreateScenarioModal - 创建情景对话框 - EditScenarioModal - 编辑情景对话框 - ConfigPanel 改造 - 分组显示系统预置和自建情景 ### Hook - useScenarios - 合并系统和自建情景，提供 CRUD 接口 ### 国际化 - 中文、英文、日文翻译支持 ## 问题修复 - 修复 CORS 问题：使用 Vite 代理 - 统一验证规则：description 可选，prompt 最小 10 字符 - 修复数据库约束：使用 NULLIF 处理空字符串 ## 文件变更 新增文件: 13 个 修改文件: 14 个 详见文档: docs/自建情景功能完整文档.md
