用c#开发微信(1)服务号的服务器配置和企业号的回调模式 - url接入 (源码下载)

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:

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

        {

            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

        {
            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));

                enText.AppendFormat("{0:x2}", b);
            }
            return enText.ToString();
        }

3. 配置文件

<system.web>
   <compilation debug="true" targetFramework="4.0" />
   <httpHandlers>
     <add verb="*" path="MPService.ashx" type="Wechat.Config.MPService,Wechat.Config" validate="true"/>
     <add verb="*" path="QYService.ashx" type="Wechat.Config.QYService,Wechat.Config" validate="true"/>
     <add verb="*" path="TestAccountService.ashx" type="Wechat.Config.TestAccountService,Wechat.Config" validate="true"/>
   </httpHandlers>
 </system.web>

 

 

如果直接用Senparc.Weixin微信开发框架来实现,就更简单了:

 

 
rotected void Page_Load(object sender, EventArgs e)
 
       private readonly string Token = ConfigurationManager.AppSettings["token"];//与微信公众账号后台的Token设置保持一致,区分大小写。
   string signature = Request["signature"];
   string timestamp = Request["timestamp"];
   string nonce = Request["nonce"];
   string echostr = Request["echostr"];
   if (Request.HttpMethod == "GET")
   {
       //get method - 仅在微信后台填写URL验证时触发
       if (CheckSignature.Check(signature, timestamp, nonce, Token))
       {
           Response.Output.Write(echostr); //返回随机字符串则表示验证通过
       }
       else
       {
           Response.Output.Write("failed:" + signature + "," + CheckSignature.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。");
       }
       Response.End();
    }
}
