从另一个网站网页获取数据 [英] get data from another website web page

问题描述

嗨小伙伴们



我想从其他网站网页获取数据，但该网页包含一个带分页的网格，当我从该网页获取数据时只给我1个索引数据。但我想得到所有页面的inedx数据，所以有没有办法从该网站获取数据或以任何方式更改pagindex（意味着点击另一页索引）



谢谢

解决方案

当然，你可以在服务器端做到这一点。当您使用ASP.NET时，所有.NET FCL都在您的服务中。在这种情况下，您需要使用类 System.Net.HttpWebRequest 。在一些简化的情况下，您可以使用类 System.Net.WebClient ：

http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.net .webclient.aspx [ ^ ]。



实际上，您尝试实现的目标需要使用 Web抓取的技术。请参阅：

如果它是一个外部站点，那么你可以做到这一点的唯一方法是查看URL以查看是否可以通过这种方式传递页面索引，或以某种方式通过Web浏览器控件自动化模拟浏览的程序。

解决方案

Of course, you can do it on server side. As you use ASP.NET, all .NET FCL is at your service. In this case, you need to use the class System.Net.HttpWebRequest. In some simplified cases, you can use the class System.Net.WebClient:
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx[^].

Actually, what you try to achieve requires use of the techniques of Web scraping. Please see:
http://en.wikipedia.org/wiki/Web_scraping[^].

You can find further detail in my past answers:
get specific data from web page[^],
How to get the data from another site[^].

Please take into account what Marcus Kramer told you in hist comment to the question. :-)

Good luck,

The only way you can do that, if it''s an external site, is to look at the URL to see if you can pass the page index that way, or somehow automate a program that simulates browsing, via a web browser control.
