这是可以找到当前有哪些服务器的地方网址,

这个项目的目的就是收集信息,并且将其生成一个html的报告(当然也可以是其他的形式的报告),完成代码如下

- #public
- agent.distribute()
- if __name__=='__main__':
- runDefaultSetup()
其实这个程序呢 在第二版的教程上有,不过呢 那个给出的服务器不能用,所以在文章的开始的时候我就给出了 可以找到服务器地址的地方,比如我这里用的就是
clpa_server='news.gmane.org'
clpa_group='gmane.comp.python.apple'
这个!
当然这段代码我也稍微说下,最开始的类NewsAgent,接着是NewsItem,NNTPSource,SimpleWebSource,PlainDestination,HTMLDestination和runDefaultSetup
程序一运行就开始跑的是runDefaultSetup,这里就将NewsAgent实例化为agent,SimpleWebSource的3个参数分别是url, title和body,然后将其实例化为bbc!
随后将bbc作为参数,调用agent的addsource。同样的道理完成了nntpsouce这一块。
最后就是就是调用agent.addDestionation。最后HTMLDestionation以news.html作为生成报告的html文本!
