asp.net WeChat development developer access skills

This article mainly introduces the relevant content of developer access in asp.net WeChat development. Friends who need it can refer to the following

First, take a look at the picture above to see what operations need to be carried out:

Create an ashx file (general handler file) in the root directory of the project or a specific folder, as shown in the figure

 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
  }
