上代码
1 using System;
2 using System.Collections.Generic;
3 using System.IO;
4 using System.Linq;
5 using System.Web;
6 using System.Web.UI;
7 using System.Web.UI.WebControls;
8 using System.Web.Security;
9
10 public partial class wx_Default : System.Web.UI.Page
11 {
12 protected void Page_Load(object sender, EventArgs e)
13 {
14 HttpContext context = HttpContext.Current;
15 string _signature = Request.QueryString["signature"];
16 string _timestamp = Request.QueryString["timestamp"];
17 string _nonce = Request.QueryString["nonce"];
18 string _echostr = Request.QueryString["echostr"];
19 string token = "linkideas";
20
21 string[] stringArray = { token, _timestamp, _nonce };
22 Array.Sort(stringArray);
23 string mergeString = string.Concat(stringArray);
24
25 mergeString = FormsAuthentication.HashPasswordForStoringInConfigFile(mergeString, "SHA1").ToLower();
26
27 if (_signature == mergeString)
28 {
29 Response.Clear();
30 Response.ContentType = "text/plain";
31 Response.Write(_echostr);
32 Response.End();
33 }
34 }
35 }
下边重写，易于理解，作用同上

16
17 HttpContext context = HttpContext.Current;
18 public void valid()
19 {
20 var echostr = context.Request["echoStr"].ToString();
21 if (checkSignature() && !string.IsNullOrEmpty(echostr))
22 {
23 Response.Clear();
24 Response.ContentType = "text/plain";
25 Response.Write(echostr);
26 Response.End();
27 }
28 }
29 public bool checkSignature()
30 {
31 var signature = context.Request["signature"].ToString();
32 var timestamp = context.Request["timestamp"].ToString();
33 var nonce = context.Request["nonce"].ToString();
34 var token = "linkideas";
35
36 string[] ArrTmp = { token, timestamp, nonce };
37 Array.Sort(ArrTmp);//字典排序
38 string mergeString = string.Concat(ArrTmp);//作用相同 string mergeString = string.Join("", ArrTmp);
39
40 mergeString = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(mergeString, "SHA1");
41 mergeString = mergeString.ToLower();
42 if (mergeString == signature)
43 {
44 return true;
45 }
46 else
47 {
48 return false;
49 }
50 }
