基本自定义示例

openclaw AI小龙虾攻略 2

我来帮你了解 OpenClaw 的自定义版本!OpenClaw 是一个优秀的网络爬虫和数据提取工具,但根据你的需求,我可以提供几种自定义方向:

核心功能自定义

    def __init__(self, config):
        self.config = {
            'delay': 1.0,          # 请求延迟
            'max_depth': 3,        # 爬取深度
            'user_agent': 'CustomBot/1.0',
            'retry_times': 3,      # 重试次数
            'timeout': 30,         # 超时时间
            **config
        }
    async def custom_fetch(self, url):
        """自定义请求方法"""
        # 添加代理、自定义头部等
        headers = {
            'User-Agent': self.config['user_agent'],
            'Accept': 'application/json',
            'Referer': 'https://example.com'
        }
        # ... 自定义逻辑

常用自定义模块

数据提取增强

class EnhancedExtractor:
    def extract_with_ai(self, html):
        """AI辅助数据提取"""
        # 集成OCR识别
        # 自然语言处理提取
        # 智能表格识别
        pass
    def dynamic_extraction(self, page, rules):
        """基于动态规则的数据提取"""
        for rule in rules:
            if rule['type'] == 'css':
                yield from page.css(rule['selector'])
            elif rule['type'] == 'xpath':
                yield from page.xpath(rule['path'])
            elif rule['type'] == 'regex':
                yield from re.findall(rule['pattern'], page.text)

反爬虫策略处理

class AntiAntiCrawler:
    def __init__(self):
        self.strategies = {
            'js_render': self.handle_js,
            'cloudflare': self.bypass_cloudflare,
            'captcha': self.solve_captcha,
            'rate_limit': self.rotate_proxies
        }
    async def bypass_protection(self, page_type):
        strategy = self.strategies.get(page_type)
        if strategy:
            return await strategy()

分布式自定义架构

# docker-compose.yml 分布式配置
version: '3'
services:
  master:
    image: custom-openclaw
    command: python master_node.py
  worker:
    image: custom-openclaw
    scale: 5
    command: python worker_node.py
  redis:
    image: redis:alpine
  storage:
    image: minio/minio

自定义数据管道

class CustomPipeline:
    def __init__(self):
        self.processors = [
            self.clean_data,
            self.validate_data,
            self.enrich_data,
            self.transform_data
        ]
    async def process_item(self, item):
        for processor in self.processors:
            item = await processor(item)
        # 存储到多个目标
        await self.save_to_db(item)
        await self.save_to_es(item)
        await self.send_to_kafka(item)

监控和日志自定义

class CustomMonitor:
    def __init__(self):
        self.metrics = {
            'requests_per_second': 0,
            'success_rate': 0,
            'data_quality': 0
        }
    def create_dashboard(self):
        """自定义监控面板"""
        # 集成 Prometheus + Grafana
        # 实时性能监控
        # 异常预警系统

快速开始模板

# custom_crawler.py
from openclaw_custom import CustomOpenClaw
async def main():
    crawler = CustomOpenClaw({
        'target': 'https://example.com',
        'concurrency': 10,
        'output_format': 'json',
        'plugins': [
            'anti_anti_crawler',
            'data_validator',
            'rate_limiter'
        ]
    })
    # 自定义回调
    @crawler.on('data_extracted')
    async def handle_data(data):
        # 自定义数据处理逻辑
        pass
    await crawler.run()
if __name__ == '__main__':
    import asyncio
    asyncio.run(main())

配置文件示例

{
  "crawler": {
    "name": "my-custom-crawler",
    "version": "2.0",
    "settings": {
      "request_timeout": 30,
      "max_retries": 5,
      "delay_range": [1, 3],
      "rotate_user_agents": true
    },
    "extractors": [
      {
        "name": "product_info",
        "type": "css",
        "selectors": {
          "title": ".product-title",
          "price": ".price",
          "description": ".description"
        }
      }
    ]
  }
}

需要我帮你:

  1. 实现特定的自定义功能吗?
  2. 优化现有 OpenClaw 配置
  3. 设计分布式爬虫架构
  4. 处理特定的反爬虫机制
  5. 构建数据清洗管道

请告诉我你的具体需求,我可以提供更详细的代码实现!
