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 name="url">模板页面路径</param>
/// <param name="encoding">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 name="html">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 name="result">Html代码</param>
/// <param name="createpath">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 name="temppath">模板地址</param>
/// <param name="path">静态页地址</param>
/// <param name="t">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:
[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;
}
}
说明：可以让一个超链接或跳转地址直接跳转到一个html的静态页面，速度会更快;
