Hi all, I have built a LocalWiki. Now I want the data of it to keep
consistent
with the Wikipedia and one work I should do is to get the data of update from Wikipedia. I get the URLs through analyzing the RSS (
http://zh.wikipedia.org/w/index.php?title=Special:%E6%9C%80%E8%BF%91%E6%9B%B... )
and get all HTML content of the edit box by analyzing these URLs after opening an URL and clicking the ’edit this page’.

That’s because I visit it too frequently and my IP address is prohibited or the network is too slow?
李琴 well.. thats webscrapping, that is a poor tecnique, one with lots of errors that generate lots of trafic.
One thing a robot must do is read and follow the http://zh.wikipedia.org/robots.txt file ( probably you sould read it too) As a general rule of Internet, a "rude" robot will be banned by the site admins.
It would be a good idea to anounce your bot as a bot in the user_agent string . Good bot beavior is one that read a website like a human. I don't know, like 10 request minute?. I don't know about this "Wikipedia" site rules about it.
What you are suffering could be automatic or manual throttling, since is detected a abusive number of request from your IP.
"Wikipedia" seems to provide fulldumps of his wiki, but are unusable for you, since are giganteous :-/, trying to rebuilt wikipedia on your PC with a snapshot would be like summoning Tchulu in a teapot. But.. I don't know, maybe the zh version is smaller, or your resources powerfull enough. One feels that what you have built has a severe overload (wastage of resources) and there must be better ways to do it...
Indeed there are. What you need: 1) the Wikimedia IRC live feed - last time I've looked at it, it was at irc://irc.wikimedia.org/ and then each project had its own channel. 2) A PHP IRC bot framework - Net_SmartIRC is well-written and easy to get started with 3) the page source you can EASILY get either in rendered form http://zh.wikipedia.org/w/index.php?title=TITLE&action=render or in raw form http://zh.wikipedia.org/w/index.php?title=TITLE&action=raw (this is page source).
