微信入门001(服务器配置)

通过url+token  =è返回signature+timestamp+nonce+echostr

 

   timestamp+nonce+ token  排序+sha1 加密=比较signature是否相等

 

注意：

  url：  只能是备案的80 域名

token：32位随机数

 timestamp：时间戳

 nonce：随机数

echostr：随机字符串

代码如下：一般处理程序 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web;
using System.Security.Authentication;
using System.Security.Cryptography;
using System.Web.Security;

namespace WebApplication1
{
    /// <summary>
    /// wx 的摘要说明
    /// </summary>
    public class wx : IHttpHandler
    {
        private string token = "hHneE6EtBEHxNamAkTsCvz5pA3mHWxT";
        public void ProcessRequest(HttpContext context)
        {
            var url = context.Request.RawUrl;

          //  /?signature=28b94e012e1d698990faf96460a904e334699c6b&echostr=3153896548757110783&timestamp=1457086219&nonce=1453006066
            //context.Response.ContentType = "text/plain";
            //context.Response.Write("Hello World");

            //三个参数排序 ==>放入数组中
            var signature = context.Request.QueryString["signature"];
            var timestamp = context.Request.QueryString["timestamp"];
            var nonce = context.Request.QueryString["nonce"];
            var echostr = context.Request.QueryString["echostr"];
            var arr = new[] { token, timestamp, nonce };
            Array.Sort(arr);
            var tmepstr = string.Join("", arr);
          var tempsignature=  FormsAuthentication.HashPasswordForStoringInConfigFile(tmepstr, "SHA1").ToLower();
          if (signature == tempsignature)
            {
                context.Response.Write(echostr); 
            }

        }

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