yispider是一款分布式爬虫平台,帮助你更好的管理和开发爬虫。 内置一套爬虫定义规则(模版),可使用模版快速定义爬虫,也可当作框架手动开发爬虫 项目地址: https://github.com/2young2simple/yispider ## 架构 目前框架分为2个部分: #### 1.爬虫部分(spider节点): 内部结构参考python scrapy框架,主要由 schedule,page process,pipline 4个部分组成,单个爬虫单独调度器,单独上下文管理,目前内置2中pipline的方式,控制台和文件,节点信息注册在etcd上用于manage节点发现。 * `core`:负责爬虫生命周期、上下文的管理,负责爬虫的运行。 * `schedule`:负责爬虫请求的调度。(目前只有一种基于channel的调度器,无法单个爬虫多worker运行,`可自行实现基于redis,或者mq服务的调度器即可实现`)<br> * `process (page process)`:负责请求结果的处理。<br> * `pipline`: 结果的输出输出到不同渠道,如控制台,文件,消息队列,数据库等等<br> * `register`:负责服务的注册(目前只支持etcd) * `http`: 提供一些http接口 #### 2.管理部分(manage节点): 负责spider节点的管理,用etcd进行spider节点的发现。通过http与spider节点通讯。 ## 开始使用 #### 1.
