怎么还有人在看这个啊，去学wcf啊

最近项目用到rest web service

rest 就不介绍了，网上多的是，闲话少说。

建一个服务器端类

namespace MyWeb
{
    public class MyjInteger : IHttpHandler
    {
        public void ProcessRequest(HttpContext context)
        {

            if (context.Request.ContentType.Equals("text/p1"))
            {
                Encoding encoding = Encoding.GetEncoding("utf-8");

Stream instream = context.Request.InputStream;

byte[] bytes = new byte[instream.Length];
instream.Read(bytes, 0, bytes.Length);

// 设置当前流的位置为流的开始
instream.Seek(0, SeekOrigin.Begin);

                string sData = encoding.GetString(bytes);
                context.Response.Write("您输入的是："+sData);
            }
            else if (context.Request.ContentType.Equals("text/p2"))
            {
                string output = context.Request.QueryString["input"].ToString();
                context.Response.Write(output);
            }
            else
            {
                context.Response.Write(context.Response.ContentType.ToString());
            }

        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

生成DLL，App_Code.dll，建一个空站点，引用这个DLL，web.config添加

</httpHandlers>

http://*/WebSite1/MyjInteger/ 这个地址就可以访问了

添加客户端页面

protected void Page_Load(object sender, EventArgs e)
{

Encoding encoding = Encoding.GetEncoding("utf-8");

        byte[] postdata = encoding.GetBytes("好啊啊啊啊"); //所有要传参数拼装
        // Prepare web request...

        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(http://*/WebSite1/MyjInteger/);
        myRequest.Method = "POST";
        myRequest.ContentType = "text/p1";
        myRequest.ContentLength = postdata.Length;
        Stream newStream = myRequest.GetRequestStream();
        // Send the data.
        newStream.Write(postdata, 0, postdata.Length);
        newStream.Close();
        // Get response
        HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
        StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
        string content = reader.ReadToEnd();

Response.Write(content);
}

返回结果：您输入的是：好啊啊啊啊

通过HttpWebRequest 方式访问，简单的rest架构，和json一起使用更加拉风
