推荐答案

我不想看到那些网站上有什么内容;没关系;无论如何，你没有解释你需要提取什么样的数据。



在所有情况下，你需要使用一些 Web抓取技术： http://en.wikipedia.org/wiki/Web_scraping [ ^ ]。



基本上，你需要采取行动像Web客户端一样，发送一些HTTP请求并获得HTTP响应。然后你需要一些东西来解析收到的内容作为回应。如果这是HTML，您将需要解析它。基本上，就是这样。



请参阅我过去的建议，了解如何做到这一切：

I don''t want to see what''s in those sites; it just does not matter; anyway, you did not explain what kind of data you need to extract.

In all cases, you need to use some technique of Web scraping: http://en.wikipedia.org/wiki/Web_scraping[^].

Basically, you need to act like a Web client, send some HTTP requests and get HTTP response. And then you need something to parse the content received in response. If this is HTML, you will need to parse it. Basically, that''s it.

Please see my past advice on how to do it all:
get specific data from web page[^],
How to get the data from another site[^].
