本文主要讲述了在asp.NET mvc中，页面静态化的方法。对于网站来说，生成纯html静态页面除了有利于seo外，还可以减轻网站的负载能力和提高网站性能。
1.先付上封装好生成静态页的原代码：
public class Common { #region 获取模板页的Html代码 /// <summary> /// 获取页面的Html代码 /// </summary> /// <param>模板页面路径</param> /// <param>页面编码</param> /// <returns></returns> public static string GetHtml(string url, System.Text.Encoding encoding) { byte[] buf = new WebClient().DownloadData(url); if (encoding != null) { return encoding.GetString(buf); } string html = System.Text.Encoding.UTF8.GetString(buf); encoding = GetEncoding(html); if (encoding == null || encoding == System.Text.Encoding.UTF8) { return html; } return encoding.GetString(buf); } /// <summary> /// 获取页面的编码 /// </summary> /// <param>Html源码</param> /// <returns></returns> public static System.Text.Encoding GetEncoding(string html) { string pattern = @"(?i)\bcharset=(?<charset>[-a-zA-Z_0-9]+)"; string charset = Regex.Match(html, pattern).Groups["charset"].Value; try { return System.Text.Encoding.GetEncoding(charset); } catch (ArgumentException) { return null; } } #endregion #region 用于生成Html静态页 /// <summary> /// 创建静态文件 /// </summary> /// <param>Html代码</param> /// <param>生成路径</param> /// <returns></returns> public static bool CreateFileHtmlByTemp(string result, string createpath) { if (!string.IsNullOrEmpty(result)) { if (string.IsNullOrEmpty(createpath)) { createpath = "/default.html"; } string filepath = createpath.Substring(createpath.LastIndexOf(@"\")); createpath = createpath.Substring(0, createpath.LastIndexOf(@"\")); if (!Directory.Exists(createpath)) { Directory.CreateDirectory(createpath); } createpath = createpath + filepath; try { FileStream fs2 = new FileStream(createpath, FileMode.Create); StreamWriter sw = new StreamWriter(fs2, new System.Text.UTF8Encoding(false));//去除UTF-8 BOM sw.Write(result); sw.Close(); fs2.Close(); fs2.Dispose(); return true; } catch (Exception ex) { throw ex; } } return false; } #endregion #region 调用静态模板，并且传递数据模型实体类 创建Html静态页 /// <summary> /// 解析模板生成静态页 /// </summary> /// <param>模板地址</param> /// <param>静态页地址</param> /// <param>数据模型</param> /// <returns></returns> public static bool CreateStaticPage<T>(string temppath, string path, T t) { try { //获取模板Html string TemplateContent = GetHtml(temppath, System.Text.Encoding.UTF8); //初始化结果 string result = string.Empty; //解析模板生成静态页Html代码 result = Razor.Parse(TemplateContent, t); //创建静态文件 return CreateFileHtmlByTemp(result, path); } catch (Exception e) { throw e; } } #endregion }
2.调用方法(创建一个多线程去执行，效果会更好)：
//实例化调用方法 Task tk = new Task(CreateStaticHtml); tk.Start(); //静态调用方法 Task.Factory.StartNew(() => CreateStaticHtml());
3.封装好的静态方法:
/// <summary> /// 创建静态页面 /// </summary> public void CreateStaticHtml() { using (BangLiEntities bangLi = new BangLiEntities()) { View_Home view_Home = new View_Home(); view_Home.CommandAdExtendList = Dal.CommandAdDal.Instance(bangLi).GetInit().ToList(); view_Home.NewsList = bangLi.News.OrderByDescending(u => u.AddDateTime).Take(5).ToList(); view_Home.NewsExtendList = Dal.NewsDal.Instance(bangLi).GetInit().OrderByDescending(u => u.AddDateTime).Take(5).ToList(); view_Home.News = Dal.NewsDal.Instance(bangLi).GetInit().Where(u => u.Id == 3).SingleOrDefault(); string TemplateContent = Common.GetHtml(Server.MapPath("/Views/SourceHtml/Home/Index.cshtml"), System.Text.Encoding.UTF8); //初始化结果 string result = string.Empty; //解析模板生成静态页Html代码 result = Razor.Parse(TemplateContent, view_Home); //创建静态文件 Common.CreateFileHtmlByTemp(result, Server.MapPath("/Resource/Manage/Html/Home/Index.html")); } }
4.如首页执行时，可以在执行Action前去执行一个过滤器:
public class MyFirstHomeAttribute:ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { var context = filterContext.HttpContext; context.Session["IsStaticHtml"] = false; string path = context.Server.MapPath("/Resource/Manage/Html/Home/Index.html"); if (System.IO.File.Exists(path)) { string html = System.IO.File.ReadAllText(path); context.Response.Write(html); context.Session["IsStaticHtml"] = true; context.Response.End(); } } }
5.执行首页:
