1. 新建一个项目,在引用中添加引用Ajax.dll,Ajax.dll位于下载的压缩包里面。
2.建立HttpHandler,在 web.config里面加上
<configuration>
<system.web>
<httpHandlers>
<add verb="POST,GET" path="ajax/*.ashx" type ="Ajax.PageHandlerFactory, Ajax" />
</httpHandlers>
...
<system.web>
</configuration>
3.新建一个类DemoMethods,这个类实现获取客户端MAC地址:
using System;
using System.Web;
namespace AjaxSample
{
/// <summary>
/// Summary description for Methods.
/// </summary>
public class DemoMethods
{
[Ajax.AjaxMethod]
public string GetCustomerMac(string clientIP) //para IP is the client's IP
{
string mac = "";
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "nbtstat";
process.StartInfo.Arguments = "-a "+clientIP;
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = true ;
process.StartInfo.RedirectStandardOutput = true;
process.Start();
string output = process.StandardOutput.ReadToEnd();
int length = output.IndexOf("MAC Address = ");
if(length>0)
{
mac = output.Substring(length+14, 17);
}
process.WaitForExit();
return mac.Replace("-", "").Trim();
}
}
}
4.写javascript,新建一个名为default,js文件如下:
function GetMac()
{
var clientIP="192.168.0.1";
document.getElementById("Mac").value=DemoMethods.GetCustomerMac(clientIP).value
alert(DemoMethods.GetCustomerMac(clientIP).value);
}
5.在某个Aspx页面放上一个html 的button
在页面上<head>中引用default.js : <script language="javascript" src="default.js"></script>
在INPUT的onclick事件中加上onclick="javascript:GetMac()"
<INPUT style="Z-INDEX: 101; LEFT: 392px; POSITION: absolute; TOP: 176px" type="button"
value="客户端获取IP" onclick="javascript:GetMac();">
6.修改Global.asax的Application_Start事件,设置Ajax的HandlerPath :
protected void Application_Start(Object sender, EventArgs e)
{
Ajax.Utility.HandlerPath = "ajax";
}
运行看看效果。是不是没有刷新就在服务器端取到客户端的MAC地址??
需要注意的是:该版本的.net Ajax需要手工在中Global.asax加上Ajax.Utility.HandlerPath = "ajax"; 配置文件web.config必须加上HttpHandler的配置信息!
该开发包的新版本还没有来得及体验,估计新版本中会方便一些,可能会去掉手动的设置Global.asax的Application_Start事件中加上Ajax.Utility.HandlerPath = "ajax";以及其他麻烦的设置!期待ing……
