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:

2.调用方法(创建一个多线程去执行,效果会更好):
1
2
3
4
5
|
//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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

[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;
