webcrawl是对抓取常用工具的封装,包括requests,lxml,phantomjs,并且实现了workflow,使coder在遵守规范的基础上更专注抓取业务,方便快速实现稳定的工程;还有一些其他会用到的工具的封装,例如rsa.py是http://www.ohdave.com/rsa 的Python版本,这个很多网站有用到;atlas.py设计到一些地图坐标的处理。
## http请求增强
handleRequest.py是对requests模块抓取常用的http方法以及lxml解析的封装,以及phantomsjs代理的支持,还有一些通用内容的处理
> - html
> - xml
> - json
> - text
> - response object
## task的简单控制
task.py(work.py)是任务流workflow的实现,是数据驱动异步执行的,类似于celery的chain,group,chord等的复合类型,但是比celery的这方面更强大更好用,并且控制着抓取代码的编写规范,依赖于pjq队列
> - workflow
> - priority
> - selfloop
> - subtask timeout
> - task timeout
## queue支持
pjq.py是priority join queue,为了支持任务流的实现,其中mongo queue比较强大,支持task的增查改,就是在执行过程中subtask是可控的。
> - workflow
> - priority
> - selfloop
> - subtask timeout
> - task timeout
