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

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Net;
 5 using System.Web;
 6 using System.Security.Authentication;
 7 using System.Security.Cryptography;
 8 using System.Web.Security;

10 namespace WebApplication1
11 {
12     /// <summary>
13     /// wx 的摘要说明
14     /// </summary>
15     public class wx : IHttpHandler
16     {
17         private string token = "hHneE6EtBEHxNamAkTsCvz5pA3mHWxT";
18         public void ProcessRequest(HttpContext context)
19         {
20             var url = context.Request.RawUrl;
21 
22           //  /?signature=28b94e012e1d698990faf96460a904e334699c6b&echostr=3153896548757110783&timestamp=1457086219&nonce=1453006066
23             //context.Response.ContentType = "text/plain";
24             //context.Response.Write("Hello World");
25 
26             //三个参数排序 ==>放入数组中
27             var signature = context.Request.QueryString["signature"];
28             var timestamp = context.Request.QueryString["timestamp"];
29             var nonce = context.Request.QueryString["nonce"];
30             var echostr = context.Request.QueryString["echostr"];
31             var arr = new[] { token, timestamp, nonce };
32             Array.Sort(arr);
33             var tmepstr = string.Join("", arr);
34           var tempsignature=  FormsAuthentication.HashPasswordForStoringInConfigFile(tmepstr, "SHA1").ToLower();
35           if (signature == tempsignature)
36             {
37                 context.Response.Write(echostr); 
38             }
39 
40         }
41 
42         public bool IsReusable
43         {
44             get
45             {
46                 return false;
47             }
48         }
49     }
50 }
