• C# .NET 微信开发-------当微信服务器推送消息时如何接收处理


    最近一直在看微信,整整一个月了,看到现在说实话还有很多没看的,从前两周一点看不懂到现在单个功能的一步步实现,不知道这样的速度是否太慢了。

    不过现在往下看还是有思路了,目前整个文档完成学习只有1/3左右,但是看过的每个接口都是测试过的。学习很重要,但是有人指引将会效率翻倍,但是谁会愿意无偿花自己的时间给你呢,所以嘛。。。就不说了,

    好了,牢骚到此,对于我这篇文章有什么不明白的或者需要交流的请加   QQ群:216390234   

    首先来门要有思路对吧,我们不是流水线的工人,而是系统的创造者,所以我们要有思想而不是一味的写代码,写到最后发现哪哪都不合适然后去修改,发现修改的时间远远大于开发的时间,那样就徒劳了。

    这篇很简单适用于刚刚入门的开发者:

    对于微信的基本配置我就不阐述了,网上讲解的很详细了。

    1、项目:MVC(不是api)

    2、

      1  public ActionResult Index()
      2         {
      3             string result = "";
      4             string postString = string.Empty;
      5             if (Request.HttpMethod.ToUpper() == "POST")
      6             {
      7                 using (Stream stream = System.Web.HttpContext.Current.Request.InputStream)
      8                 {
      9                     Byte[] postBytes = new Byte[stream.Length];
     10                     stream.Read(postBytes, 0, (Int32)stream.Length);
     11                     postString = Encoding.UTF8.GetString(postBytes);
     12                     if (!string.IsNullOrEmpty(postString))
     13                     {
     14                         string SendToWx = string.Empty;
     15                         //这里写方法解析Xml
     16                         XmlDocument xml = new XmlDocument();//
     17                         xml.LoadXml(postString);
     18                         XmlElement xmlElement = xml.DocumentElement;
     19                         //这里进行判断MsgType
     20                         switch (xmlElement.SelectSingleNode("MsgType").InnerText)
     21                         {
