YiSpider

A distributed spider platform

介绍

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

计划

增加了更多例子。
内置实现了基于redis的调度器。
正在准备管理网页端部分的制作，敬请期待。

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。(基于 channel 或 redis 的调度器)
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。

请求介绍

初始请求（Request）Url有2种语法糖方式,用于简便易用：

1. http://xxx/xxx/{begin-end,offset}

start = 0 20 40 ... 10000
url = https://movie.douban.com/j/new_search_subjects?sort=T&range=0,10&tags=&start={0-10000,20}

2. http://xxx/xxx/{aa|bb|cc}

start = 0 20 40 60
url = https://movie.douban.com/j/new_search_subjects?sort=T&range=0,10&tags=&start={0|20|40|60}

3.http://www.dilidili.wang{$href} (AddQueue特有)

如果 href = "/abc" (href是process解析出的参数)
url = http://www.dilidili.wang{$href}
url = http://www.dilidili.wang/abc
url = https://movie.douban.com/j/new_search_subjects?sort=T&range=0,10&tags=&start={0-$count,20}
等等

实例

1. Json模版

http接口调用
curl -d '{"id":"douban-movie","Name":"douban-movie","request":[{"url":"https://movie.douban.com/j/new_search_subjects?sort=T\u0026range=0,10\u0026tags=\u0026start={0-100,20}","method":"get","type":"","data":null,"header":null,"cookies":{"url":"","data":""},"process_name":"movie"}],"process":[{"name":"movie","reg_url":null,"type":"json","template_rule":{"Rule":null},"json_rule":{"Rule":{"casts":"casts","cover":"cover","id":"id","node":"array|data","rate":"rate","star":"star","title":"title","url":"url"}},"add_queue":null}],"pipline":"file","depth":0,"end_count":0}' "http://127.0.0.1:7774/task/addAndRun"
