yispider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 .

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)
-
process (page process)：负责请求结果的处理。
-
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
-
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。
