ASP.NET -- 一般处理程序ashx
如果在一个html页面向服务器端请求数据，可用ashx作为后台页面处理数据。ashx适合用作数据后台处理，相当于WebForm中的aspx.cs文件或aspx.vb文件。
入门案例：html页面向ashx页面请求数据，ashx作为后台页面返回数据。
前端html页面：
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/><title>My Test ashx</title> ???<script type="text/javascript" src="./js/jquery-2.0.3.min.js" ></script> ???<script type="text/javascript" > ???????$(function() { ???????????$("#btn_Test").click(function() { ???????????????$.ajax({ ???????????????????type: "post", ???????????????????url: "Test.ashx", ???????????????????datatype: "text", ???????????????????data: { "TestAction":"getBaiduUrl"}, ???????????????????success: function(data) { ??????????????????????$("#myDiv1").html(data); ???????????????????} ???????????????}); ???????????}); ???????}); ???</script></head><body> ???<button type="button" id="btn_Test">Test</button> ???<div id="myDiv1" style="width:300px;height:30px;padding: 10px;border:2px solid blue;"> ???</div> ??</body></html>后台Test.ashx页面：
<%@ WebHandler Language="C#" Class="Test" %>using System;using System.Web;public class Test : IHttpHandler { ???????public void ProcessRequest (HttpContext context) { ???????context.Response.ContentType = "text/plain"; ???????if (context.Request["TestAction"] == "getBaiduUrl") ???????{ ???????????context.Response.Write("百度的地址是: https://www.baidu.com"); ???????} ???} ????public bool IsReusable { ???????get { ???????????return false; ???????} ???}}运行结果：
