实现基于 Scrapy + FastAPI + Vue3 的企业级分布式爬虫系统,支持微博、CSDN、知乎等平台的数据采集。 ## 主要功能 - ✅ 分布式爬取架构 (Scrapy-Redis) - ✅ RESTful API (FastAPI + SQLAlchemy 2.0) - ✅ 任务调度系统 (APScheduler) - ✅ 智能去重机制 (Redis + PostgreSQL) - ✅ 反爬策略 (代理池、UA轮换、智能重试) - ✅ 可观测性接入 (OpenTelemetry) - ✅ K8s部署配置 (Argo CD GitOps) ## 技术栈 - Backend: FastAPI 0.109 + SQLAlchemy 2.0 + AsyncPG - Spider: Scrapy 2.11 + Scrapy-Redis 0.7 - Database: PostgreSQL 16 + Redis 7 - Deployment: Docker + Kubernetes + Argo CD ## 测试结果 ✅ 知乎爬虫 - "中国梦" 关键词: 5条数据 ✅ 微博爬虫 - "健康" 关键词: 6条数据 ✅ 数据库存储、去重、查询功能正常 详见 TEST_REPORT.md 和 README.md 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
