asp.net WeChat 開発開発者のアクセス スキル

この記事では主に、asp.net WeChat 開発における開発者アクセスに関する関連コンテンツを紹介します。必要な友人は参照してください

まず、上の図を見て、どのような操作を実行する必要があるかを確認してください。

図に示すように、プロジェクトのルートディレクトリまたは特定のフォルダーにashxファイル（汎用ハンドラーファイル）を作成します

 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
  }
