C#实现微信开发前奏

不想废话，直接写了！因为是留给自己做随笔的，所以大神们看到别喷……

1.必须有微信公众账号

2.你也可以申请测试微信号，链接给你 http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login

然后，建立mvc,你只需要点几下vs就帮你搞定了。这不废话

接着，要创建一个一般处理程序，随便起个名字，测试通过才是重点，抓紧时间……

/// <summary>
        /// 验证微信签名
        /// </summary>
        /// <returns></returns>
        /// * 将token、timestamp、nonce三个参数进行字典序排序
        /// * 将三个参数字符串拼接成一个字符串进行sha1加密
        /// * 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信。
        private bool CheckSignature()
        {
            var token = "token"; 
            var signature = HttpContext.Current.Request.QueryString["signature"];
            var timestamp = HttpContext.Current.Request.QueryString["timestamp"];
            var nonce = HttpContext.Current.Request.QueryString["nonce"];
            var echostr = HttpContext.Current.Request.QueryString["echostr"];
            string[] ArrTmp = { token, timestamp, nonce };
            Array.Sort(ArrTmp);     //字典排序
            var tmpStr = string.Join("", ArrTmp);
            tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1");//加密方式

            if (tmpStr.ToLower() == signature)
            {
                return true;
            }
            return false;
        }

这代码相当于是跟微信公众号中【开发】--》【基本配置】里面你所写的Token 一个一对一令牌通信握手，只要互相通了，那么你就算是搞定了！

搞定是后话，还有工作没做完，擦，，接着写！

怎么配置，这是问题，哎只能用花生壳给测试先，至少要知道玩了半天是不是通的！

看下图：左边花生壳配置-----右边iis网站发布绑定

看到这图，你也明白下一步怎么玩了吧。本地iis配上了域名。这简直屌爆了…………

下面。我们加上代码。设置发送和自动回复测试，看看能不能玩

 #region 接收消息
        /// <summary>
        /// 接收微信发送的XML消息并且解析
        /// </summary>
        private void ReceiveXml()
        {
            var requestStream = HttpContext.Current.Request.InputStream;
            var requestByte = new byte[requestStream.Length];
            requestStream.Read(requestByte, 0, (int)requestStream.Length);
            var requestStr = Encoding.UTF8.GetString(requestByte);

            if (!string.IsNullOrEmpty(requestStr))
            {
                //封装请求类
                var requestDocXml = new XmlDocument();
                requestDocXml.LoadXml(requestStr);
                var rootElement = requestDocXml.DocumentElement;

                };
