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

  6             string[] sites = paras[7].Split('|');

  7             string[] parms = paras[8].Split('|');

3.创建ACTIVEX,继续一端JS脚本。

 

var ZHTools = 

{

    _err : false,

    _tsArray : [],

    _getInstance : function() {

        if(this._tsArray.length > 0){

            for (var y=0;y<this._tsArray.length; y++) {

                if(this._tsArray[y] && this._tsArray[y].State){

                    if(this._tsArray[y].State == 0 || this._tsArray[y].State == 4)

                    {

                        this._tsArray[y] = null;

                        this._tsArray.splice(y,1);

                        return this._tsArray[this._tsArray.length] = this._createZHTools();

                    }

                }

            }

        }

        this._tsArray[this._tsArray.length] = this._createZHTools();

        if(this._tsArray[this._tsArray.length-1]){

           return this._tsArray[this._tsArray.length-1];

        }

        else{

           return null;

        }

    },

    _createZHTools :  function () {

        try{

            var objTools = new ActiveXObject("ZHDAPS.Tools.2");

            if(!objTools){

                ZHTools._err = true;

                ZHTools._showDownloadMsg();

            }

           if(objTools.State){

              objTools.State = 1;

           }

        }

        catch(e){

            //显示ActiveX控件下载

           ZHTools._err = true;

           ZHTools._showDownloadMsg();

        }

        return objTools;

    },

    _send: function (tid,domain,port,path,method,params,flag,refUrl,referer,charset,callback){

        if(!ZHTools._err){

            var tools = this._getInstance();

            if(tools){

                with(tools)

                {

                    try

                    {

                        OnDataChanged = callback;

                        Send(tid,domain,port,path,method,params,flag,refUrl,referer,charset);

                    }

                    catch(e)

                    {

                        alert(e);

                    }

                }

            }

        }

    },

    clear : function(){

       for (var y=0;y<this._tsArray.length; y++) {

                this._tsArray[y].Dispose();

                this._tsArray[y] = null;

                this._tsArray.splice(y,1);

        }

    },

    _showDownloadMsg : function(){

         if(confirm('请安装智汇工具插件\n此工具需要ZHSoft 客户端插件支持,您确认要下载吗(此插件是安全的)？')){

             window.location.href = "http://www.cnblogs.com/install/ClientDlls.htm";

         }

    }

    

}

 

 

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。
