从网站结果页面捕获价格 [英] Capturing the price from website results page

问题描述

我想知道你是否可以从网站上获取价格清单（在我的案例中是一个图书网站）。



与搜索提交中的不同可以看到代码是如何使用的，但是在结果页面上你不能这样。



这里有一个例子：



http://www.abebooks.com/servlet/SearchResults?bi=0&bx=off&ds=30&isbn=9781551927282&recentlyadded=all&sortby=2&sts=t& ; x = 46& y = 11 [ ^ ]



我想捕获它出现的第一个价格并将其与其他信息一起放入数据库。这可能吗？ （我是新手，所以对我来说可能不那么明显）



我想我必须使用gridview才能做到这一点？



非常感谢。

Hi, I am wondering if you can capture the list of prices from a website (in my case a book website).

Unlike in the search submission you can see how the code is used but here at the results page you cant.

here is an example:

http://www.abebooks.com/servlet/SearchResults?bi=0&bx=off&ds=30&isbn=9781551927282&recentlyadded=all&sortby=2&sts=t&x=46&y=11[^]

I want to capture the first price it comes up and put it into a database along with other information. Is this possible? (im a newbie so it might not be so obvious for me)

I think I have to use gridview in order to this right?

thanks alot.

推荐答案

您需要使用网络爬虫/屏幕抓取工具。抓取，抓取和存储数据的行为与在页面上显示数据完全不同。



澄清：您需要抓取页面以获取数据我想。看看网站是否有您可以使用的API可能是值得的。





查看网络爬虫的本地示例：一个使用C＃套接字的简单爬虫



使用C＃for ASP.NET进行屏幕刮擦 [ ^ ]

You'll need to use a web crawler/screen scraper. The act of crawling, scraping and storing the data is completely separate from displaying this on your page.

Clarification: You'll need to scrape the page for the data you'd like. It may be worth while to see if the website has an API you can consume.
