git clone https://github.com/my8100/logparser.git cd logparser python setup.py install 使用方法
作为 service 运行
- 请先确保当前主机已经安装和启动 Scrapyd
- 通过命令
logparser启动 LogParser - 访问 http://127.0.0.1:6800/logs/stats.json (假设 Scrapyd 运行于端口 6800)
- 访问 http://127.0.0.1:6800/logs/projectname/spidername/jobid.json 以获取某个爬虫任务的日志分析详情
配合 ScrapydWeb 实现爬虫进度可视化
