主要增强功能

架构改进

# 新的模块化架构
class EnhancedOpenClaw:
    def __init__(self):
        self.downloader = SmartDownloader()
        self.parser = AdaptiveParser()
        self.scheduler = DistributedScheduler()
        self.storage = MultiFormatStorage()
        self.anti_block = AntiBlockSystem()

核心增强特性

A. 智能解析引擎

自动识别网页结构（列表、详情页等）
CSS选择器 + XPath + 正则表达式混合解析
机器学习辅助的内容识别
动态页面渲染支持（集成Playwright/Selenium）

B. 分布式抓取系统

基于Redis的分布式任务队列
支持水平扩展
负载均衡和故障转移
断点续爬功能

C. 反反爬虫机制

智能请求频率控制
自动代理池管理
User-Agent轮换
浏览器指纹模拟
验证码识别（OCR集成）

配置示例

# config.yaml
project:
  name: "enhanced_openclaw"
  version: "2.0"
spider:
  name: "example_spider"
  start_urls: ["https://example.com"]
  allowed_domains: ["example.com"]
  downloader:
    concurrent_requests: 10
    delay: 0.5
    timeout: 30
    retry_times: 3
  parser:
    auto_detect: true
    fallback_selectors:
      - css
      - xpath
      - regex
  anti_block:
    enabled: true
    proxy_pool: "redis://localhost:6379/0"
    user_agent_rotation: true
    browser_fingerprint: true
  storage:
    formats:
      - json
      - csv
      - database
    database:
      type: "postgresql"
      connection: "postgresql://user:pass@localhost/db"

代码实现示例

from enhanced_openclaw import OpenClawEnhanced
from enhanced_openclaw.plugins import *
import asyncio
class MyEnhancedSpider(OpenClawEnhanced):
    def __init__(self):
        super().__init__(
            name="my_spider",
            plugins=[
                AutoDetectPlugin(),
                DynamicPagePlugin(browser_type="chromium"),
                AntiBlockPlugin(
                    proxy_strategy="rotating",
                    request_delay="smart"
                )
            ]
        )
    async def parse(self, response):
        # 智能解析 - 自动探测数据模式
        data = await self.auto_parse(response)
        # 或者使用传统方式
        items = response.css('.product-item')
        for item in items:
            yield {
                'title': item.css('h2::text').get(),
                'price': item.css('.price::text').get(),
                'url': response.urljoin(item.css('a::attr(href)').get())
            }
        # 自动翻页
        next_page = await self.find_next_page(response)
        if next_page:
            yield self.Request(next_page, callback=self.parse)
async def main():
    spider = MyEnhancedSpider()
    # 配置爬虫
    await spider.configure(
        start_urls=["https://example.com/products"],
        concurrent_requests=5,
        request_delay=(0.5, 1.5),  # 随机延迟
        depth_limit=3,
        export_format=["json", "postgresql"]
    )
    # 运行爬虫
    results = await spider.crawl()
    # 获取统计数据
    stats = spider.get_statistics()
    print(f"抓取完成: {stats['pages_crawled']} 页面")
if __name__ == "__main__":
    asyncio.run(main())

监控与管理界面

# Web管理面板
from enhanced_openclaw.dashboard import create_dashboard
app = create_dashboard("OpenClaw 增强版控制台",
    features=[
        "实时监控",
        "任务管理",
        "性能分析",
        "数据预览",
        "日志查看"
    ]
)
# 运行: uvicorn dashboard:app --host 0.0.0.0 --port 8000

高级功能

A. 数据管道

from enhanced_openclaw.pipelines import DataPipeline
pipeline = DataPipeline([
    CleanPipeline(),      # 数据清洗
    ValidatePipeline(),   # 数据验证
    DeduplicatePipeline(),# 去重
    EnrichPipeline(),     # 数据增强
    ExportPipeline()      # 导出
])

B. 规则学习

# 自动学习网站结构
from enhanced_openclaw.learning import RuleLearner
learner = RuleLearner()
rules = learner.learn_from_examples(
    urls=["https://example.com/products/1", "https://example.com/products/2"],
    sample_data={"title": "Product Name", "price": "$19.99"}
)

C. API接口

from enhanced_openclaw.api import OpenClawAPI
api = OpenClawAPI()
api.add_endpoint(
    "/crawl",
    method="POST",
    handler=api.start_crawling,
    params={"url": "string", "config": "dict"}
)
