## 基本設定
### API 端點
- **Base URL:** `http://localhost:3002/api/v1`
- **Method:** `POST`
- **Content-Type:** `application/json`
- **Authentication:** `X-API-Key: YOUR_API_KEY` (所有 `/api/v1/*` 端點皆需要)

## Workflow 1: 基礎搜尋
### Trigger: Manual / Webhook
```
[Manual Trigger]
[HTTP Request] → POST http://localhost:3002/api/v1/search
[Set] → 設定搜尋詞 "charade"
[Code] → 處理回傳結果
[Respond]
```
### HTTP Request 設定
```json
{
"url": "http://localhost:3002/api/v1/search",
"method": "POST",
"body": {
"query": "={{ $json.searchTerm }}",
"limit": 5
},
"options": {
"headers": {
"Content-Type": "application/json",
"X-API-Key": "YOUR_API_KEY"
}
}
}
```
### Code (處理結果)
```javascript
const results = $input.first().json.results;
const videoUrl = "https://wp.momentry.ddns.net/Old_Time_Movie_Show_-_Charade_1963.HD.mov";
return results.map(r => ({
chunk_id: r.chunk_id,
text: r.text,
start: r.start_time,
end: r.end_time,
score: r.score,
video_url: `${videoUrl}#t=${r.start_time},${r.end_time}`
}));
```

## Workflow 2: n8n 專用格式
使用 `/n8n/search` 端點(已包含 file_path
### HTTP Request
```json
{
"url": "http://localhost:3002/api/v1/n8n/search",
"method": "POST",
"body": {
"query": "={{ $json.searchTerm }}",
"limit": 5
},
"options": {
"headers": {
"Content-Type": "application/json",
"X-API-Key": "YOUR_API_KEY"
}
}
}
```
### 回傳格式
```json
{
"query": "charade",
"count": 5,
"hits": [
{
"id": "sentence_0006",
"vid": "a1b10138a6bbb0cd",
"start": 48.8,
"end": 55.44,
"title": "Chunk sentence_0006",
"text": "fun plot twists...",
"score": 0.526,
"file_path": "/Users/accusys/momentry/var/sftpgo/data/demo/video.mp4"
}
]
}
```
> **注意**: API 現在返回 `file_path`(檔案系統路徑)而非 `media_url`(網頁 URL)。如需在網頁中播放影片,請將檔案路徑轉換為可訪問的 URL(例如透過 SFTPGo 分享連結)。

## Workflow 3: 訊息機器人整合
### Telegram Bot 範例
```
[Webhook: Telegram]
[Extract: /search charade]
[HTTP Request] → POST /api/v1/search
[Format Response]
[Telegram: Send Message]
```
### 回傳格式
```
🎬 搜尋結果: "charade"
1. "fun plot twists, Woody Dialog and charming performances..."
⏱ 48.8s - 55.4s
📊 分數: 0.526
2. "Don't you like me to say that a pretty girl..."
⏱ 4745.6s - 4748.6s
📊 分數: 0.525
```

## Workflow 4: 多影片搜尋
### 取得所有影片
```
[HTTP Request]
GET http://localhost:3002/api/v1/videos
```
### 依 UUID 篩選
```json
{
"query": "charade",
"limit": 5,
"uuid": "a1b10138a6bbb0cd"
}
```
---
## Workflow 5: 定時更新
```
[Cron: 每小時]
[HTTP Request] → GET /api/v1/videos
[Loop Over Items]
[Check: 新影片?]
[Process: 執行 vectorize]
```
---
## 實用場景
### 1. 客服機器人
用戶問「這部片在哪一段有談到 charade?」
→ 搜尋 API → 回傳時戳 → 直接播放該片段
### 2. 內容推薦
根據用戶輸入的關鍵字,找到相關影片片段
### 3. 自動化剪輯
搜尋多個片段 → 組合成精華影片
---
## 錯誤處理
```javascript
const response = $input.first();
if (!response.json.results || response.json.results.length === 0) {
return {
success: false,
message: "找不到相關結果"
};
}
return {
success: true,
count: response.json.results.length,
data: response.json.results
};
```
---
## 測試用 cURL
```bash
# 基本搜尋
curl -X POST http://localhost:3002/api/v1/search \
-H "Content-Type: application/json" \
-H "X-API-Key: YOUR_API_KEY" \
-d '{"query": "charade", "limit": 3}'
# n8n 格式
curl -X POST http://localhost:3002/api/v1/n8n/search \
-H "Content-Type: application/json" \
-H "X-API-Key: YOUR_API_KEY" \
-d '{"query": "charade", "limit": 3}'
# 取得影片列表
curl -H "X-API-Key: YOUR_API_KEY" http://localhost:3002/api/v1/videos
# 取得特定影片的區塊
curl -H "X-API-Key: YOUR_API_KEY" http://localhost:3002/api/v1/videos/a1b10138a6bbb0cd/chunks
```
