废话不多说，直接上代码

2. c#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace WebApplication2
{
/// <summary>
/// Handler1 的摘要说明
/// </summary>
public class Handler1 : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
if (context.Request["data"] != null)
{
context.Response.Write("C#接口"+context.Request["data"].ToString());
return;
}
context.Response.Write("C#接口");
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
3. 执行结果
4. 增加一点 别忘了权限
