{
  "engagementRate": "={{ ($json.comments / ($json.score || 1)) * 100 }}"
}

// 争议分数
{
  "controversyScore": "={{ (1 - $json.upvoteRatio) * 100 }}"
}

// 讨论密度
{
  "discussionDensity": "={{ $json.comments / Math.max($json.text.length / 100, 1) }}"
}
```

### 内容分析

从 Reddit 内容中提取洞察：

```json
{
  "name": "Extract Keywords",
  "type": "n8n-nodes-base.function",
  "parameters": {
    "functionCode": `
      const text = $input.first().json.text.toLowerCase();
      const keywords = text.match(/\\b\\w{4,}\\b/g) || [];
      const wordCount = {};

      keywords.forEach(word => {
        wordCount[word] = (wordCount[word] || 0) + 1;
      });

      const topKeywords = Object.entries(wordCount)
        .sort(([,a], [,b]) => b - a)
        .slice(0, 10)
        .map(([word, count]) => ({ word, count }));

      return [{ json: { ...item.json, topKeywords } }];
    `
  }
}
```

## 错误处理

### 常见错误

#### 子版块未找到

**错误：** `404 - Subreddit not found`

**解决方案：**
- 验证子版块名称拼写是否正确
- 检查子版块是否为私密或被封禁
- 在批量操作中优雅地处理缺失的子版块

#### 帖子已删除

**错误：** `404 - Post not found`

**解决方案：**
- 帖子可能已被用户或版主删除
- 首次访问时存储帖子数据
- 为缺失帖子实现回退逻辑

#### 达到速率限制

**错误：** `429 - Too many requests`

**解决方案：**
- 在请求之间添加延迟（推荐：2-3 秒）
- 实现指数退避重试逻辑
- 考虑升级 API 计划以获得更高限制
