I also found an answer on this post which points towards some ideas but I think is pre MVC6/Asp Core: RSS Feeds in ASP.NET MVC
推荐答案// action to return the feed [Route("site/GetRssFeed/{type}")] public IActionResult GetRssFeed(ArticleStatusTypes type) { var feed = _rss.BuildXmlFeed(type); return Content(feed, "text/xml"); } public string BuildXmlFeed(ArticleStatusTypes type) { var key = $"RssFeed{Convert.ToInt32(type)}{_appInfo.ApplicationId}"; var articles = _cache.GetCachedData(key) ?? _cache.SetCache(key, _service.GetItems(Convert.ToInt32(type), _appInfo.CacheCount)); StringWriter parent = new StringWriter(); using (XmlTextWriter writer = new XmlTextWriter(parent)) { writer.WriteProcessingInstruction("xml-stylesheet", "title=\"XSL_formatting\" type=\"text/xsl\" href=\"/skins/default/controls/rss.xsl\""); writer.WriteStartElement("rss"); writer.WriteAttributeString("version", "2.0"); writer.WriteAttributeString("xmlns:atom", "www.w3/2005/Atom"); // write out writer.WriteStartElement("channel"); // write out -level elements writer.WriteElementString("title", $"{_appInfo.ApplicationName} {type}" ); writer.WriteElementString("link", _appInfo.WebsiteUrl); //writer.WriteElementString("description", Description); writer.WriteElementString("ttl", "60"); writer.WriteStartElement("atom:link"); //writer.WriteAttributeString("href", Link + Request.RawUrl.ToString()); writer.WriteAttributeString("rel", "self"); writer.WriteAttributeString("type", "application/rss+xml"); writer.WriteEndElement(); if (articles != null) { foreach (var article in articles) { writer.WriteStartElement("item"); writer.WriteElementString("title", article.Title); writer.WriteElementString("link", _appInfo.WebsiteUrl); // todo build article path writer.WriteElementString("description", article.Summary); writer.WriteEndElement(); } } // write out writer.WriteEndElement(); // write out writer.WriteEndElement(); } return parent.ToString(); }
