feat: 实现RAG Grounding服务功能
基于promptx/outfit-match中的query_llm_with_grounding实现，遵循Tauri开发规范 ## 新增功能 - 实现RAG Grounding核心服务逻辑 - 支持基于Vertex AI Search的检索增强生成 - 集成Cloudflare Gateway和Google Gemini API - 提供完整的TypeScript类型定义和前端服务封装 ## 技术架构 - Rust后端：GeminiService扩展RAG功能 - Tauri命令：query_rag_grounding, test_rag_grounding_connection, get_rag_grounding_config - 前端服务：RagGroundingService类，支持统计监控和错误处理 - 数据模型：完整的请求/响应结构和配置管理 ## 核心特性 - 检索增强生成：基于数据存储的智能检索和内容生成 - 容错机制：内置重试机制和错误处理 - 性能监控：响应时间统计和性能指标 - 类型安全：完整的TypeScript类型定义 - 会话管理：支持上下文保持的对话功能 ## 测试覆盖 - 25个单元测试，覆盖核心功能和边界情况 - 包括序列化/反序列化、错误处理、配置验证等 - 所有测试通过，确保功能正确性 ## 文档和示例 - 完整的API文档 (docs/rag-grounding-api.md) - 详细的使用示例 (examples/rag-grounding-usage.ts) - 包含最佳实践和错误处理指南 ## 遵循规范 - 严格遵循promptx/tauri-desktop-app-expert开发规范 - 安全第一：最小权限原则，数据加密保护 - 性能优先：异步处理，响应时间优化 - 模块化设计：清晰的架构分层 - 错误处理完善：全面的错误处理和用户反馈

# RAG Grounding API 文档
|
||||
|
||||
## 概述
|
||||
|
||||
RAG Grounding 服务基于 Google Vertex AI Search 和 Gemini 模型，提供检索增强生成（Retrieval-Augmented Generation）功能。该服务参考了 `promptx/outfit-match` 项目中的 `query_llm_with_grounding` 实现，遵循 Tauri 桌面应用开发规范。
|
||||
|
||||
## 核心特性
|
||||
|
||||
- **检索增强生成**：基于数据存储的智能检索和内容生成
|
||||
- **Cloudflare Gateway 集成**：通过 Cloudflare Gateway 访问 Google Vertex AI
|
||||
- **容错机制**：内置重试机制和错误处理
|
||||
- **类型安全**：完整的 TypeScript 类型定义
|
||||
- **性能监控**：响应时间统计和性能指标
|
||||
|
||||
## API 接口
|
||||
|
||||
### 1. 查询 RAG Grounding
|
||||
|
||||
**命令**: `query_rag_grounding`
|
||||
|
||||
**请求参数**:
|
||||
```typescript
|
||||
interface RagGroundingRequest {
|
||||
user_input: string; // 用户查询内容
|
||||
config?: RagGroundingConfig; // 可选配置
|
||||
session_id?: string; // 会话ID
|
||||
}
|
||||
```
|
||||
|
||||
**响应数据**:
|
||||
```typescript
|
||||
interface RagGroundingResponse {
|
||||
answer: string; // AI 生成的回答
|
||||
grounding_metadata?: GroundingMetadata; // Grounding 元数据
|
||||
response_time_ms: number; // 响应时间（毫秒）
|
||||
model_used: string; // 使用的模型
|
||||
}
|
||||
```
|
||||
|
||||
**使用示例**:
|
||||
```typescript
|
||||
import { queryRagGrounding } from '../services/ragGroundingService';
|
||||
|
||||
const result = await queryRagGrounding("如何搭配牛仔裤？", {
|
||||
sessionId: "user-session-123",
|
||||
customConfig: {
|
||||
temperature: 0.7,
|
||||
max_output_tokens: 4096
|
||||
}
|
||||
});
|
||||
|
||||
if (result.success) {
|
||||
console.log("回答:", result.data?.answer);
|
||||
console.log("来源:", result.data?.grounding_metadata?.sources);
|
||||
} else {
|
||||
console.error("查询失败:", result.error);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 测试连接
|
||||
|
||||
**命令**: `test_rag_grounding_connection`
|
||||
|
||||
**响应数据**: `string` - 连接测试结果
|
||||
|
||||
**使用示例**:
|
||||
```typescript
|
||||
import { testRagGroundingConnection } from '../services/ragGroundingService';
|
||||
|
||||
const status = await testRagGroundingConnection();
|
||||
console.log("服务状态:", status.available ? "可用" : "不可用");
|
||||
console.log("测试结果:", status.connectionTest);
|
||||
```
|
||||
|
||||
### 3. 获取配置信息
|
||||
|
||||
**命令**: `get_rag_grounding_config`
|
||||
|
||||
**响应数据**:
|
||||
```typescript
|
||||
interface RagGroundingConfigInfo {
|
||||

## 配置选项
|
||||
|
||||
### RagGroundingConfig
|
||||
|
||||
```typescript
|
||||
interface RagGroundingConfig {
|
||||

||||
}
|
||||
```
|
||||
|
||||
### 默认配置
|
||||
|
||||
```typescript
|
||||
const DEFAULT_CONFIG = {
|
||||
project_id: "gen-lang-client-0413414134",
|
||||
location: "global",
|
||||
data_store_id: "default_data_store",
|
||||
model_id: "gemini-2.5-flash",
|
||||
temperature: 1.0,
|
||||
max_output_tokens: 8192,
|
||||
};
|
||||
```
|
||||
|
||||
## Grounding 元数据
|
||||
|
||||
### GroundingMetadata
|
||||
|
||||
```typescript
|
||||
interface GroundingMetadata {
|
||||
sources: GroundingSource[]; // 检索来源
|
||||
search_queries: string[]; // 搜索查询
|
||||
}
|
||||
```
|
||||
|
||||
### GroundingSource
|
||||
|
||||
```typescript
|
||||
interface GroundingSource {
|
||||
title: string; // 来源标题
|
||||
uri?: string; // 来源URI
|
||||
snippet: string; // 内容片段
|
||||
relevance_score?: number; // 相关性评分 (0.0-1.0)
|
||||
}
|
||||
```
|
||||
|
||||
## 错误处理
|
||||
|
||||
### 错误类型
|
||||
|
||||
```typescript
|
||||
enum RagGroundingErrorType {
|
||||
NETWORK_ERROR = 'NETWORK_ERROR', // 网络错误
|
||||
AUTHENTICATION_ERROR = 'AUTHENTICATION_ERROR', // 认证错误
|
||||
CONFIGURATION_ERROR = 'CONFIGURATION_ERROR', // 配置错误
|
||||
TIMEOUT_ERROR = 'TIMEOUT_ERROR', // 超时错误
|
||||
PARSING_ERROR = 'PARSING_ERROR', // 解析错误
|
||||
UNKNOWN_ERROR = 'UNKNOWN_ERROR', // 未知错误
|
||||
}
|
||||
```
|
||||
|
||||
### 错误处理示例
|
||||
|
||||
```typescript
|
||||
try {
|
||||
const result = await queryRagGrounding("测试查询");
|
||||
if (!result.success) {
|
||||
switch (result.error) {
|
||||
case 'NETWORK_ERROR':
|
||||
console.error("网络连接失败，请检查网络设置");
|
||||
break;
|
||||
case 'AUTHENTICATION_ERROR':
|
||||
console.error("认证失败，请检查API密钥");
|
||||
break;
|
||||
default:
|
||||
console.error("查询失败:", result.error);
|
||||
}
|
||||
}
|
||||
} catch (error) {
|
||||
console.error("系统错误:", error);
|
||||
}
|
||||
```
|
||||
|
||||
## 性能监控
|
||||
|
||||
### 统计信息
|
||||
|
||||
```typescript
|
||||
interface RagGroundingStats {
|
||||
totalQueries: number; // 总查询次数
|
||||
successfulQueries: number; // 成功查询次数
|
||||
failedQueries: number; // 失败查询次数
|
||||
averageResponseTime: number; // 平均响应时间
|
||||
fastestResponseTime: number; // 最快响应时间
|
||||
slowestResponseTime: number; // 最慢响应时间
|
||||
lastQueryTime?: Date; // 最后查询时间
|
||||
}
|
||||
```
|
||||
|
||||
### 获取统计信息
|
||||
|
||||
```typescript
|
||||
import { getRagGroundingStats } from '../services/ragGroundingService';
|
||||
|
||||
const stats = getRagGroundingStats();
|
||||
console.log(`成功率: ${(stats.successfulQueries / stats.totalQueries * 100).toFixed(2)}%`);
|
||||
console.log(`平均响应时间: ${stats.averageResponseTime.toFixed(0)}ms`);
|
||||
```
|
||||
|
||||
## 最佳实践
|
||||
|
||||
### 1. 查询优化
|
||||
|
||||
- 使用清晰、具体的查询语句
|
||||
- 适当设置温度参数（创意性 vs 准确性）
|
||||
- 合理设置最大输出令牌数
|
||||
|
||||
### 2. 会话管理
|
||||
|
||||
- 为相关查询使用相同的 session_id
|
||||
- 定期清理过期会话
|
||||
|
||||
### 3. 错误处理
|
||||
|
||||
- 实现重试机制
|
||||
- 提供用户友好的错误信息
|
||||
- 记录详细的错误日志
|
||||
|
||||
### 4. 性能优化
|
||||
|
||||
- 监控响应时间
|
||||
- 缓存常见查询结果
|
||||
- 使用适当的超时设置
|
||||
|
||||
## 开发规范
|
||||
|
||||
本 RAG Grounding 服务严格遵循 `promptx/tauri-desktop-app-expert` 中定义的开发规范：
|
||||
|
||||
- **安全第一**：最小权限原则，数据加密保护
|
||||
- **性能优先**：异步处理，响应时间优化
|
||||
- **类型安全**：完整的 TypeScript 类型定义
|
||||
- **模块化设计**：清晰的架构分层
|
||||
- **错误处理完善**：全面的错误处理和用户反馈
