最近研究了下服务号的服务器配置和企业号的回调模式。真正实现完后，觉得很简单，但一开始还是走了点弯路，所以写了个web程序，只用改下配置文件里的参数就可以直接用了。下面介绍下详细的用法以及实现步骤。
一、用法
1. 下载web程序
http://yunpan.cn/cjeTSAKwUVmv9 访问密码 7ab3
2. 修改配置文件web.config
<appSettings>
<!--微信的Token-->
<add key="WeixinToken" value="dd"/>
<add key="AppId" value="wxdbddd2bc"/>
<add key="AppSecret" value="82f7ddd88e196"/>
<!--企业号配置信息-->
<add key="CorpToken" value="fddd"/>
<add key="CorpId" value="wx1156d982ddda8"/>
<add key="EncodingAESKey" value="aNvJOkGYddyGwf5Rg"/>
</appSettings>
3. 发布到你的服务器上
4. 服务号和企业号里分别填上url及参数：
企业号：
服务号：
二、实现方法
1. 新建一个web程序
2. 添加二个ashx文件（这里不用aspx页面，是为了更简便），参考官方文档，实现校验流程
服务号：

public class MPService : IHttpHandler { public void ProcessRequest(HttpContext context) { string postString = string.Empty; if (HttpContext.Current.Request.HttpMethod.ToUpper() == "GET") { Auth(); } } public bool IsReusable { get { return false; } } /// <summary> /// 处理微信服务器验证消息 /// </summary> private void Auth() { string token = ConfigurationManager.AppSettings["WeixinToken"].ToString(); string signature = HttpContext.Current.Request.QueryString["signature"]; string timestamp = HttpContext.Current.Request.QueryString["timestamp"]; string nonce = HttpContext.Current.Request.QueryString["nonce"]; string echostr = HttpContext.Current.Request.QueryString["echostr"]; if (HttpContext.Current.Request.HttpMethod.ToUpper() == "GET") { //get method - 仅在微信后台填写URL验证时触发 if (CheckSignature(signature, timestamp, nonce, token)) { WriteContent(echostr); //返回随机字符串则表示验证通过 } else { WriteContent("failed:" + signature + "," + GetSignature(timestamp, nonce, token) + "。" + "如果你在浏览器中看到这句话，说明此地址可以被作为微信公众账号后台的Url，请注意保持Token一致。"); } HttpContext.Current.Response.End(); } } private void WriteContent(string str) { HttpContext.Current.Response.Output.Write(str); } /// <summary> /// 检查签名是否正确 /// </summary> /// <param name="signature"></param> /// <param name="timestamp"></param> /// <param name="nonce"></param> /// <param name="token"></param> /// <returns></returns> public static bool CheckSignature(string signature, string timestamp, string nonce, string token) { return signature == GetSignature(timestamp, nonce, token); } /// <summary> /// 返回正确的签名 /// </summary> /// <param name="timestamp"></param> /// <param name="nonce"></param> /// <param name="token"></param> /// <returns></returns> public static string GetSignature(string timestamp, string nonce, string token) { string[] arr = new[] { token, timestamp, nonce }.OrderBy(z => z).ToArray(); string arrString = string.Join("", arr); System.Security.Cryptography.SHA1 sha1 = System.Security.Cryptography.SHA1.Create(); byte[] sha1Arr = sha1.ComputeHash(Encoding.UTF8.GetBytes(arrString)); StringBuilder enText = new StringBuilder(); foreach (var b in sha1Arr) { enText.AppendFormat("{0:x2}", b); } return enText.ToString(); } }
