先上图,看一看需要进行哪些项目的操作:




在项目的根目录或者特定的文件夹内,创建一个ashx文件(一般处理程序文件),如图

public void ProcessRequest(HttpContext context)
    {
      context.Response.ContentType = "text/plain";
     
      string postString = string.Empty;
      if (HttpContext.Current.Request.HttpMethod.ToUpper() == "POST")
      {
        using (Stream stream = HttpContext.Current.Request.InputStream)
        {
          Byte[] postBytes = new Byte[stream.Length];
          stream.Read(postBytes, 0, (Int32)stream.Length);
          postString = Encoding.UTF8.GetString(postBytes);
        }

        if (!string.IsNullOrEmpty(postString))
        {
          ResponseXML(postString);//返回给微信用户信息
        }

        ///加载自定义菜单
