    operations.append(ReplaceOne(
        {"message_id": message["message_id"]},
        message,
        upsert=True
    ))

result = await collection.bulk_write(operations, ordered=False)
```

## 📈 使用场景

### 1. 社媒情绪监控

```python
# 监控股票社媒情绪变化
async def monitor_social_sentiment(symbol: str):
    service = await get_social_media_service()
    
    # 获取最近24小时的社媒消息
    end_time = datetime.utcnow()
    start_time = end_time - timedelta(hours=24)
    
    params = SocialMediaQueryParams(
        symbol=symbol,
        start_time=start_time,
        end_time=end_time,
        limit=1000
    )
    
    messages = await service.query_social_media_messages(params)
    
    # 分析情绪趋势
    sentiment_trend = analyze_sentiment_trend(messages)
    
    return sentiment_trend
```

### 2. 内部研究整合

```python
# 整合内部研究观点
async def aggregate_internal_views(symbol: str):
    service = await get_internal_message_service()
    
    # 获取最新研究报告
    reports = await service.get_research_reports(symbol, limit=10)
    
    # 获取分析师笔记
    notes = await service.get_analyst_notes(symbol, limit=20)
    
    # 综合分析
    consensus = analyze_internal_consensus(reports + notes)
    
    return consensus
```

### 3. 跨平台数据分析

```python
# 跨平台消息数据分析
async def cross_platform_analysis(symbol: str):
    social_service = await get_social_media_service()
    internal_service = await get_internal_message_service()
    
    # 获取社媒数据
    social_messages = await social_service.query_social_media_messages(
        SocialMediaQueryParams(symbol=symbol, limit=500)
    )
    
    # 获取内部数据
    internal_messages = await internal_service.query_internal_messages(
        InternalMessageQueryParams(symbol=symbol, limit=100)
    )
    
    # 综合分析
    analysis = {
        "social_sentiment": calculate_social_sentiment(social_messages),
        "internal_consensus": calculate_internal_consensus(internal_messages),
        "data_consistency": check_data_consistency(social_messages, internal_messages),
        "recommendation": generate_recommendation(social_messages, internal_messages)
    }
    
    return analysis
```

## 🎯 爬虫最佳实践

### 1. 数据质量控制

#### 去重策略
```python
# 基于message_id和platform的唯一约束
{
    "message_id": "weibo_123456789",
    "platform": "weibo",
    # MongoDB会自动处理重复数据
}

# 在爬虫中实现去重检查
async def check_message_exists(message_id: str, platform: str) -> bool:
    service = await get_social_media_service()
    existing = await service.query_social_media_messages(
        SocialMediaQueryParams(message_id=message_id, platform=platform, limit=1)
    )
    return len(existing) > 0
```

#### 数据验证
```python
# 消息数据验证
def validate_social_media_message(message: dict) -> bool:
    required_fields = ['message_id', 'platform', 'content', 'author', 'publish_time']

    # 检查必填字段
    for field in required_fields:
        if field not in message or not message[field]:
            return False

    # 检查内容长度
    if len(message['content']) < 10 or len(message['content']) > 10000:
        return False

    # 检查时间格式
    try:
        datetime.fromisoformat(message['publish_time'])
    except ValueError:
        return False

    return True
```

#### 异常处理
```python
# 完善的错误处理
async def safe_crawl_messages(crawler, symbol: str, max_retries: int = 3):
    for attempt in range(max_retries):
        try:
            messages = await crawler.crawl_stock_messages(symbol)
            return messages
        except aiohttp.ClientError as e:
            logger.warning(f"网络错误 (尝试 {attempt + 1}/{max_retries}): {e}")
            if attempt < max_retries - 1:
                await asyncio.sleep(2 ** attempt)  # 指数退避
        except Exception as e:
            logger.error(f"爬取失败: {e}")
            break

    return []
```

### 2. 性能优化

#### 并发控制
```python
# 使用信号量控制并发数
import asyncio

async def crawl_multiple_symbols(symbols: List[str], max_concurrent: int = 5):
    semaphore = asyncio.Semaphore(max_concurrent)

    async def crawl_with_semaphore(symbol: str):
        async with semaphore:
            return await crawl_symbol_messages(symbol)

    tasks = [crawl_with_semaphore(symbol) for symbol in symbols]
    results = await asyncio.gather(*tasks, return_exceptions=True)

    return results
```

#### 批量操作优化
```python
# 批量保存优化
async def batch_save_messages(messages: List[dict], batch_size: int = 100):
    service = await get_social_media_service()

    for i in range(0, len(messages), batch_size):
        batch = messages[i:i + batch_size]
        try:
            result = await service.save_social_media_messages(batch)
            logger.info(f"批次 {i//batch_size + 1}: 保存 {result['saved']} 条消息")
        except Exception as e:
            logger.error(f"批次保存失败: {e}")
            # 尝试单条保存
            for msg in batch:
                try:
                    await service.save_social_media_messages([msg])
                except Exception as single_error:
                    logger.error(f"单条消息保存失败: {single_error}")
```

#### 缓存策略
```python
# 使用Redis缓存已处理的消息ID
import redis.asyncio as redis

class MessageCache:
    def __init__(self):
        self.redis = redis.Redis.from_url("redis://localhost:6379")

    async def is_processed(self, message_id: str) -> bool:
        return await self.redis.exists(f"processed:{message_id}")

    async def mark_processed(self, message_id: str, ttl: int = 86400):
        await self.redis.setex(f"processed:{message_id}", ttl, "1")
```

### 3. 安全控制

#### 访问权限管理
```python
# 内部消息权限检查
def check_access_permission(user_role: str, message_access_level: str) -> bool:
    permission_hierarchy = {
        'public': ['public'],
        'internal': ['public', 'internal'],
        'restricted': ['public', 'internal', 'restricted'],
        'confidential': ['public', 'internal', 'restricted', 'confidential']
    }

    user_permissions = {
        'guest': ['public'],
        'employee': ['public', 'internal'],
        'manager': ['public', 'internal', 'restricted'],
        'admin': ['public', 'internal', 'restricted', 'confidential']
    }

    allowed_levels = user_permissions.get(user_role, ['public'])
    return message_access_level in allowed_levels
```

#### 数据脱敏
```python
# 敏感信息脱敏
def sanitize_message_content(content: str, access_level: str) -> str:
    if access_level in ['restricted', 'confidential']:
        # 脱敏处理
        content = re.sub(r'\d{11}', '***********', content)  # 手机号
        content = re.sub(r'\d{15,18}', '******************', content)  # 身份证
        content = re.sub(r'[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}', '***@***.***', content)  # 邮箱

    return content
```

#### 审计日志
```python
# 操作审计日志
class AuditLogger:
    def __init__(self):
        self.logger = logging.getLogger('audit')

    async def log_crawl_operation(self, operation: str, symbol: str, count: int, user: str = "system"):
        audit_record = {
            "timestamp": datetime.utcnow().isoformat(),
            "operation": operation,
            "symbol": symbol,
            "message_count": count,
            "user": user,
            "source": "crawler"
        }

        self.logger.info(json.dumps(audit_record, ensure_ascii=False))

        # 可选：保存到数据库
        # await save_audit_record(audit_record)
```

### 4. 监控和告警

#### 爬虫健康检查
```python
# 爬虫健康状态监控
class CrawlerHealthMonitor:
    def __init__(self):
        self.last_success_time = {}
        self.error_counts = {}

    async def check_crawler_health(self, crawler_name: str) -> dict:
        last_success = self.last_success_time.get(crawler_name)
        error_count = self.error_counts.get(crawler_name, 0)

        health_status = {
            "crawler": crawler_name,
            "status": "healthy",
            "last_success": last_success,
            "error_count": error_count,
            "timestamp": datetime.utcnow().isoformat()
        }

        # 检查健康状态
        if last_success:
            time_since_success = datetime.utcnow() - last_success
            if time_since_success > timedelta(hours=6):
                health_status["status"] = "warning"
            if time_since_success > timedelta(hours=24):
                health_status["status"] = "critical"

        if error_count > 10:
            health_status["status"] = "critical"
        elif error_count > 5:
            health_status["status"] = "warning"

        return health_status

    def record_success(self, crawler_name: str):
        self.last_success_time[crawler_name] = datetime.utcnow()
        self.error_counts[crawler_name] = 0

    def record_error(self, crawler_name: str):
        self.error_counts[crawler_name] = self.error_counts.get(crawler_name, 0) + 1
```

#### 数据质量监控
```python
# 数据质量指标监控
async def monitor_data_quality():
    social_service = await get_social_media_service()
    internal_service = await get_internal_message_service()

    # 获取最近24小时的数据
    end_time = datetime.utcnow()
    start_time = end_time - timedelta(hours=24)

    # 社媒消息质量检查
    social_stats = await social_service.get_social_media_statistics(
        start_time=start_time, end_time=end_time
    )

    # 内部消息质量检查
    internal_stats = await internal_service.get_internal_statistics(
        start_time=start_time, end_time=end_time
    )

    quality_report = {
        "timestamp": datetime.utcnow().isoformat(),
        "social_media": {
            "total_messages": social_stats.total_count,
            "sentiment_distribution": {
                "positive": social_stats.positive_count,
                "negative": social_stats.negative_count,
                "neutral": social_stats.neutral_count
            },
            "avg_engagement_rate": social_stats.avg_engagement_rate,
            "platforms": social_stats.platforms
        },
        "internal_messages": {
            "total_messages": internal_stats.total_count,
            "message_types": internal_stats.message_types,
            "avg_confidence": internal_stats.avg_confidence,
            "departments": internal_stats.departments
        }
    }

    # 质量告警检查
    alerts = []
    if social_stats.total_count < 100:  # 24小时内消息数过少
        alerts.append("社媒消息数量异常偏低")

    if social_stats.avg_engagement_rate < 0.01:  # 平均互动率过低
        alerts.append("社媒消息互动率异常偏低")

    if internal_stats.avg_confidence < 0.6:  # 平均置信度过低
        alerts.append("内部消息置信度异常偏低")

    quality_report["alerts"] = alerts

    return quality_report
```
