小红书

### Installation

Dependencies are already installed:
```bash
pip install aiohttp loguru pycryptodome getuseragent
```

### Basic Usage

```python
import asyncio
import sys
sys.path.insert(0, r'C:\\Users\\Chocomint\\.openclaw\\workspace\\xiaohongshu\\scripts')

from request.web.xhs_session import create_xhs_session

async def main():
    # ✅ 推荐：不强制代理（有代理再填 proxy）
    # 说明：当前小红书接口经常对“未登录/游客”限制搜索能力。
    # 如果 search 报 code=-104（未登录无权限），请提供 web_session。
    xhs = await create_xhs_session(proxy=None, web_session="YOUR_WEB_SESSION_OR_NONE")

    # Search notes
    res = await xhs.apis.note.search_notes("美妆")
    data = await res.json()
    print(data)

    await xhs.close_session()

asyncio.run(main())
```

## Core Capabilities

### 1. Search & Discovery

**Search notes by keyword:**
```python
res = await xhs_session.apis.note.search_notes("口红")
```

**Get home feed (trending):**
```python
# 注意：get_homefeed 需要 category 参数
res = await xhs_session.apis.note.get_homefeed(
    xhs_session.apis.note.homefeed_category_enum.FOOD
)
```

**Get note detail:**
```python
# note_detail 需要 note_id + xsec_token（有时在搜索结果 item 里叫 xsec_token）
res = await xhs_session.apis.note.note_detail(note_id, xsec_token)
```

### 2. User Interactions

**Get user info:**
```python
res = await xhs_session.apis.auth.get_self_simple_info()
```

**Follow a user:**
```python
res = await xhs_session.apis.user.follow_user(user_id)
```

**Like a note:**
```python
res = await xhs_session.apis.note.like_note(note_id)
```

### 3. Comments

**Get comments for a note:**
```python
# comments 也需要 note_id + xsec_token
res = await xhs_session.apis.comments.get_comments(note_id, xsec_token)
```

## Configuration

### Proxy

代理不是硬性要求（本技能可以 `proxy=None` 运行）。但在以下情况建议使用代理：
- 网络环境不稳定/请求超时
- 频繁触发风控（例如 461）想换出口 IP 试试

**不使用代理：**
```python
xhs = await create_xhs_session(proxy=None, web_session=None)
```

**使用代理：**
```python
xhs = await create_xhs_session(
    proxy="http://127.0.0.1:7890",
    web_session="your_web_session_cookie"  # 需要登录能力时再提供
)
```

### Encryption Parameters

All encryption parameters are automatically generated:
- **Cookies**: a1, webId, acw_tc, web_session, sec_poison_id, websectiga, gid
- **Headers**: x-s, x-s-common, x-t, x-b3-traceid, x-xray-traceid

Configuration file: `scripts/request/web/encrypt/web_encrypt_config.ini`

## Session Management

### Guest Mode (No Login)
```python
xhs_session = await create_xhs_session(proxy="http://127.0.0.1:7890")
```

### Authenticated Mode (With Login)
```python
xhs_session = await create_xhs_session(
    proxy="http://127.0.0.1:7890",
    web_session="030037afxxxxxxxxxxxxxxxxxxxaeb59d5b4"  # Your cookie
)
```

### Close Session
```python
await xhs_session.close_session()
```

## Links & IDs (重要)

- 小红书笔记的公开标识通常是 **note_id（十六进制风格字符串）**，例如：`697cc945000000000a02cdad`。
- 这个 note_id **可以做数学意义的 16 进制→10 进制转换**，但那只是“另一种表示法”，**不会变成小红书的短数字 ID（类似 App Store 的 id741292507）**，也不会更适合拼接小红书链接。
- 我们通过接口得到的可直接打开的网页链接通常形如：
  - `https://www.xiaohongshu.com/explore/<note_id>?xsec_token=...&xsec_source=pc_search`
- **xhslink.com 短链**一般需要在 App/登录态里通过“分享→复制链接”获得；仅靠当前接口通常拿不到。

### 输出到聊天时的链接美化（推荐）
为了避免长链接难看，优先用**文本标签超链接**：
- Markdown：`[标题](https://www.xiaohongshu.com/explore/...)`

## Available APIs

All APIs are accessible via `xhs_session.apis.*`:

**Authentication (`apis.auth`):**
- `get_self_simple_info()` - Get current user info

**Notes (`apis.note`):**
- `search_notes(keyword)` - Search notes by keyword
- `get_homefeed(category)` - Get home feed
- `note_detail(note_id, share_token)` - Get note details
- `like_note(note_id)` - Like a note

**Comments (`apis.comments`):**
- `get_comments(note_id, share_token)` - Get note comments

**User (`apis.user`):**
- `follow_user(user_id)` - Follow a user
- `get_user_info(user_id)` - Get user details

## Example Workflows

### Workflow 1: Search and Extract Notes

```python
async def search_example():
    xhs_session = await create_xhs_session(proxy="http://127.0.0.1:7890")

    # Search for makeup tutorials
    res = await xhs_session.apis.note.search_notes("美妆教程")
    data = await res.json()

    for note in data['data']['items']:
        print(f"Title: {note['display_title']}")
        print(f"Author: {note['user']['nickname']}")
        print(f"Likes: {note['liked_count']}")
        print("---")

    await xhs_session.close_session()
```

### Workflow 2: Get Comments for Analysis

```python
async def comments_example():
    xhs_session = await create_xhs_session(proxy="http://127.0.0.1:7890")

    note_id = "64f1a2d30000000013003689"
    res = await xhs_session.apis.comments.get_comments(note_id, "")
    data = await res.json()

    for comment in data['data']['comments']:
        print(f"User: {comment['user']['nickname']}")
        print(f"Content: {comment['content']}")
        print(f"Likes: {comment['like_count']}")
        print("---")

    await xhs_session.close_session()
```

### Workflow 3: User Profile Analysis

```python
async def profile_example():
    xhs_session = await create_xhs_session(
        proxy="http://127.0.0.1:7890",
        web_session="your_cookie_here"
    )

    # Get self info
    res = await xhs_session.apis.auth.get_self_simple_info()
    data = await res.json()

    print(f"Username: {data['data']['user']['nickname']}")
    print(f"Followers: {data['data']['user']['follows']}")
    print(f"Fans: {data['data']['user']['fans']}")

    await xhs_session.close_session()
```

## Important Notes

1. **Proxy is required** for most operations due to XiaoHongShu's anti-scraping measures
2. **Rate limiting**: Be respectful with request frequency to avoid IP bans
3. **Authentication**: Some operations require login (web_session cookie)
4. **Legal compliance**: Use only for legitimate research and data analysis purposes

## Technical Details

Based on [RedCrack](https://github.com/Cialle/RedCrack) - Pure Python reverse engineering of XiaoHongShu's encryption algorithms.

**What's automatically handled:**
- Base64/Base58 custom encoding
- RC4/XOR encryption
- MD5/SHA256 hashing
- Custom signature generation (x-s, x-s-common)
- Dynamic cookie generation (a1, webId, sec_poison_id, etc.)

**No JavaScript runtime required** - All encryption is pure Python.

## Troubleshooting

### Connection errors
- Verify your proxy is running on the configured port
- Try different proxy servers if needed
- Check network connectivity

### 461 errors（风控/安全校验）
- 这通常不是代码语法问题，而是触发了小红书的风控/安全校验。
- 典型现象：`OtherStatusError: 461异常`，或者接口返回看似 success=true 但 HTTP=461。

应对建议：
- 降低频率/加随机 sleep、避免并发
- 换关键词/换 endpoint（例如先用搜索拿到 note_id + xsec_token，再查 detail）
- 使用稳定的登录态（web_session）
- 必要时更换代理出口

### 401/403 errors
- web_session 可能过期
- 小红书可能更新了风控参数/签名逻辑（需要更新逆向实现）

### Import errors
- Ensure all dependencies are installed: `pip install aiohttp loguru pycryptodome getuseragent`
- Check that the skill path is correct in `sys.path.insert()`
