将动态页面转成静态页面

在App_Code文件下新建两个类:

static_htm类用来处理将动态页面转化成静态页面。

如下:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;

/// <summary>
/// static_htm 的摘要说明
/// </summary>
public class static_htm : System.Web.UI.Page {
 public static_htm()
 {
  //
  // TODO: 在此处添加构造函数逻辑
  //
 }

    protected override void Render(HtmlTextWriter writer)
    {
        StringWriter sw = new StringWriter();
        HtmlTextWriter htmlw = new HtmlTextWriter(sw);
        //调用Render方法,把页面内容输出到StringWriter中

        base.Render(htmlw);
        htmlw.Flush();
        htmlw.Close();
        //获得页面内容
        string pageContent = sw.ToString();
        string path = Server.MapPath("~/CacheFile/");
        if (!Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }
        string pageUrl = StaticFileCacheModule.GetFileName(HttpContext.Current);
        if (!File.Exists(pageUrl))
        {
            //把页面内容保存到静态文件中
            using (StreamWriter stringWriter = File.CreateText(path + pageUrl))
            {
                stringWriter.Write(pageContent);
            }
        }
        //将页面内容输出到浏览器
        Response.Write(pageContent);

    }


}

 

StaticFileCacheModule类用来处理哪些动态页面需要转化成静态页面的,

如下:

 

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;

/// <summary>
/// StaticFileCacheModule 的摘要说明
/// </summary>
public class StaticFileCacheModule : IHttpModule
{
 public StaticFileCacheModule()
 {
  //
  // TODO: 在此处添加构造函数逻辑
  //
        Console.WriteLine();
 }


    public void Dispose()
    {
        
    }

    public void Init(HttpApplication context)
    {
        context.BeginRequest += new EventHandler(context_BeginRequest); 
    }
    private void context_BeginRequest(object sender, EventArgs e)
    {

        HttpContext context = ((HttpApplication)sender).Context;

        //判断是否需要处理

        if (context.Request.AppRelativeCurrentExecutionFilePath.ToLower().EndsWith(".aspx"))
        {

            string fileUrl = "~/CacheFile/";

            string fileName = GetFileName(context);

            string filePath = context.Server.MapPath(fileUrl) + fileName;

            if (File.Exists(filePath))
            {

                //如果静态缓存文件存在,直接返回缓存文件

                context.RewritePath(fileUrl + fileName, false);

            }
           

        }
    }


    public static string GetFileName(HttpContext context)
    {

        //我们的缓存文件名由页面文件名加上查询字符串组成

        return context.Request.AppRelativeCurrentExecutionFilePath.ToLower()

            .Replace(".aspx", "").Replace("~/", "").Split('/')[context.Request.AppRelativeCurrentExecutionFilePath.ToLower()

            .Replace(".aspx", "").Replace("~/", "").Split('/').Length - 1]

            + context.Request.Url.Query.Replace("?", "__").Replace("&", "_") + ".html";

    }

}

 

 

配置Web.Config文件,如下:

 

<httpModules>
   <add name="StaticFileCache"  type="StaticFileCacheModule"/>
 </httpModules>

 

最后:

希望要转成静态页面的动态页面继承static_htm:

 

如:

 

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : static_htm
{
    protected void Page_Load(object sender, EventArgs e)
    {
       

    }

}
