使用ashx解决ajax跨域访问的问题

由于跨域访问是被IE的安全访问拒绝掉的

需要使用web代理

新建一个proxy.ashx文件

在proxy.ashx里建一个webservice

代码如下：

[WebService(Namespace= 

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

public class Proxy:IHttpHandler

{

     public void ProcessRequest(HttpContext context)

     {

           string url = context.Request.QueryString["url"];

            WebRequest request = HttpWebRequest.Create(url);

           WebResponse response = request.GetResponse();

           Stream stream = response.GetResponseStream();

            StreamReader reader = new StreamReader(stream);

           context.Response.ContentType = response.ContentType;

           context.Response.Write(reader.ReadToEnd());

           reader.Close();

            stream.Close();

           response.Close();

     }

}

调用: window.location = "proxy.ashx?url=http://www.baidu.com";
