    }

2、獲取POST請求過來的數據。（於2020-03-28 更新）

/// <summary>
/// 接受用戶發送的消息
/// </summary>
[HttpPost]
public string Indexs()
{
  string postString = "無數據";
  if (HttpContext.Request.HttpMethod.ToUpper() == "POST")
  {
      string xmlPath = string.Empty;
      Response.ContentType = "text/plain";
      using (Stream stream = HttpContext.Request.InputStream)
      {
          Byte[] postBytes = new Byte[stream.Length];
          stream.Read(postBytes, 0, (Int32)stream.Length);
          postString = Encoding.UTF8.GetString(postBytes);
          if (string.IsNullOrEmpty(postString))
          {

              postString = "沒有數據";
          }
          StreamWriter str = new StreamWriter(@"F:\數據打印.txt", true, Encoding.UTF8);
          str.WriteLine(postString);
          str.Close();
      }
  }
  return postString;
}
