對于網(wǎng)站來說，生成純html靜態(tài)頁面除了有利于seo外，還可以減輕網(wǎng)站的負(fù)載能力和提高網(wǎng)站性能。本篇文章主要介紹了ASP.NET MVC生成靜態(tài)頁面的方法，有興趣的可以了解一下。

本文主要講述了在asp.NET mvc中，頁面靜態(tài)化的方法。對于網(wǎng)站來說，生成純html靜態(tài)頁面除了有利于seo外，還可以減輕網(wǎng)站的負(fù)載能力和提高網(wǎng)站性能。

1.先付上封裝好生成靜態(tài)頁的原代碼：

public class Common
{
  #region 獲取模板頁的Html代碼
  /// <summary>
  /// 獲取頁面的Html代碼
  /// </summary>
  /// <param name="url">模板頁面路徑</param>
  /// <param name="encoding">頁面編碼</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>
  /// 獲取頁面的編碼
  /// </summary>
  /// <param name="html">Html源碼</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靜態(tài)頁
  /// <summary>
  /// 創(chuàng)建靜態(tài)文件
  /// </summary>
  /// <param name="result">Html代碼</param>
  /// <param name="createpath">生成路徑</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 調(diào)用靜態(tài)模板，并且傳遞數(shù)據(jù)模型實體類 創(chuàng)建Html靜態(tài)頁
  /// <summary>
  /// 解析模板生成靜態(tài)頁
  /// </summary>
  /// <param name="temppath">模板地址</param>
  /// <param name="path">靜態(tài)頁地址</param>
  /// <param name="t">數(shù)據(jù)模型</param>
  /// <returns></returns>
  public static bool CreateStaticPage<T>(string temppath, string path, T t)
  {
    try
    {
      //獲取模板Html
      string TemplateContent = GetHtml(temppath, System.Text.Encoding.UTF8);

      //初始化結(jié)果
      string result = string.Empty;

      //解析模板生成靜態(tài)頁Html代碼
      result = Razor.Parse(TemplateContent, t);

      //創(chuàng)建靜態(tài)文件
      return CreateFileHtmlByTemp(result, path);
    }
    catch (Exception e)
    {
      throw e;
    }
  }
  #endregion
}

2.調(diào)用方法(創(chuàng)建一個多線程去執(zhí)行，效果會更好)：

//實例化調(diào)用方法
Task tk = new Task(CreateStaticHtml);
tk.Start();
//靜態(tài)調(diào)用方法
Task.Factory.StartNew(() => CreateStaticHtml());

3.封裝好的靜態(tài)方法:

/// <summary>
/// 創(chuàng)建靜態(tài)頁面
/// </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);
    //初始化結(jié)果
    string result = string.Empty;
    //解析模板生成靜態(tài)頁Html代碼
    result = Razor.Parse(TemplateContent, view_Home);
    //創(chuàng)建靜態(tài)文件
    Common.CreateFileHtmlByTemp(result, Server.MapPath("/Resource/Manage/Html/Home/Index.html"));
  }
}

4.如首頁執(zhí)行時，可以在執(zhí)行Action前去執(zhí)行一個過濾器:

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.執(zhí)行首頁:

[MyFirstHome]
public ActionResult Index()
{
  View_Home view_Home = null;
  var IsStaticHtml = Convert.ToBoolean(Session["IsStaticHtml"]);
  if (!IsStaticHtml)
  {
    view_Home = new View_Home();
    using (BangLiEntities bangLi = new BangLiEntities())
    {
      view_Home.CommandAdExtendList = Dal.CommandAdDal.Instance(bangLi).GetInit().ToList();
      view_Home.NewsExtendList = Dal.NewsDal.Instance(bangLi).GetInit().OrderByDescending(u => u.AddDateTime).Take(5).ToList();
          
    }
    return View(view_Home);
  }
  else
  {
    return null;
  }
}

說明：可以讓一個超鏈接或跳轉(zhuǎn)地址直接跳轉(zhuǎn)到一個html的靜態(tài)頁面，速度會更快;
