服务器A上的一个页面,要请求服务器B上的一个处理程序,这就叫做跨域请求
本次的测试页面为:
处理程序kimhandler.ashx,如下:
%@ WebHandler Language="C#" Class="KimHandler" %> using System; using System.Web; public class KimHandler : IHttpHandler { public void ProcessRequest (HttpContext context) { string msg = "{\"name\":\"kim\",\"gender\":\"男\",\"age\":24}"; context.Response.Write(msg); } public bool IsReusable { get { return false; } } }
另一张处理程序handler.ashx如下:
<%@ WebHandler Language="C#" Class="Handler" %> using System; using System.Web; public class Handler : IHttpHandler { public void ProcessRequest (HttpContext context) { string callbackName = context.Request.Params["callbackFun"]; string msg = callbackName+ "({\"name\":\"kim\",\"age\":\"18\"});"; context.Response.Write(msg); } public bool IsReusable { get { return false; } } }
2.Ajax无法实现跨域请求
