asp.net微信开发（开发者接入)


            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

  }
