使用AJAX,JAVASCRIPT,.NET,ATL 项目打造超快速信息采集系统
大家好，我们一起来研究一个信息采集系统的设计，如果您有更好的方案请在评论中阐述 谢谢
近期做了一个在线工具网站 http://www.webtool.cn/, 网站整体采用AJAX设计，全静态处理。
在项目中需要访问一些网络资源，并进行资源处理。
但是遇到了以下几个问题。
1.服务端处理压力过重，如果访问量较大 那么势必会影响整体速度；
2.如果使用AJAX去访问网络资源，那么会有跨域权限问题；
3.如果某工具的使用量比较大，那么以服务端IP去频繁爬某一网络资源很有可能会被封IP。
综合以上的问题，我们想到了用客户端去采集网络资源，并使用JS正则分析的方式去处理。
好，现在开始说说怎样来完成这一系列工作:
首先，请看看效果：
http://www.webtool.cn/tools/list/n2399997.htm
此工具名为网上购物价格比较，可以迅速实时的获取包括淘宝网、拍拍网、易趣网、京东网、当当网、卓越网在内的大型B2C,C2C购物网站数据，并进行数据处理
为客户提供一个商品比较的功能。
我们先看看使用的效果图
此列表是可以展开的，可以查看更多的商品，并且可以通过链接直接到达商品的内容页面。
怎么实现的呢？
第一步，javascript 通过AJAX 访问位于服务端的C#代码，获取返回的结果框架和JS函数，这些函数主要是用于提供ACTIVEX 调用的回调函数。
sys.tools.getResults(...)
第二步,C#返回responseText和脚本
来一段代码

当插件已经被安装的时候开始创建插件并调用，如果没有安装就提示安装。
在插件中需要使用多线程，然后使用IDispatch.Invoke方法调用页面中的JS回调函数。
关于更多的技术细节，将在后面的章节中加入。谢谢阅读。
