艾偉_轉載:ASP.NET模板引擎技術

狼人2007發表於2019-05-14

  以前聽我朋友說起php的模板引擎技術的時候似懂非懂哪時感覺真的很強,一直在想asp.net有這種技術嗎?我不知道我的理解是不是對的.其實 asp.net的模板引擎技術就是先建好一個靜態的html頁面我們稱它為模板頁,你如果有不同形式的頁面哪就得建立不同的靜態模板頁,然後在後臺用檔案操作往這個檔案裡寫東西然後在把這個模板頁另存到一個靜態頁面的目錄,不好意思可能我的理解太俗,如果有更好的理解和想法可以在apolov發文章告訴我謝謝。現在我附加一下程式碼

  Default.aspx這個頁面只有幾個textbox控制元件和兩個按妞控制元件

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" 
ValidateRequest
="false" Inherits="ToHtml._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Asp.net生成靜態頁</title>
</head>
<body>
<form id="form1" runat="server">
<div>
標題:
<asp:TextBox ID="txtTitle" runat="server" Width="352px"></asp:TextBox><br />
內容:
<asp:TextBox ID="txtContent" runat="server" Height="179px"
TextMode
="MultiLine"Width="350px"></asp:TextBox><br />
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click"
Text
="根據模板生成" />
   <
br />
<br />
<br />
Url地址:
<asp:TextBox ID="txtUrl" runat="server" ToolTip="請確認Url地址的存在"
    Width
="359px"></asp:TextBox>
<br />
<br />
<asp:Button ID="Button2" runat="server" Text="根據Url地址生成"
OnClick
="Button2_Click" />
</
div>
</form>
</body>
</html>

  要準備的模板頁程式碼,htm檔案頁面比較簡單,如果有興趣的朋友可以做成更復雜的模板頁嘿嘿

!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title> $title$ 生成靜態頁title>
<style type="text/css">
<!--
.STYLE1
{
font-size
: 16px;
font-weight
: bold;
}
-->
</style>
</head>
<body>
<br />
<br />
<table width="100%" border="0" bgcolor="#339900">
<tr>
<td height="34" align="center" bgcolor="#FFFFFF"><span class="STYLE1">$title$ </span>
</
td>
</tr>
<tr>
<td height="42" bgcolor="#FFFFFF"><br />
<br />
內容:$content$
</td>
</tr>
</table>

</body>
</html>

  後臺生成靜態頁面的程式碼Default.aspx.cs主要用到了檔案操做

ing 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.Net;

using System.IO;
namespace ToHtml
{
//51aspx.com生成靜態頁演示檔案,轉載請保留該資訊
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
//根據模板生成,保持在html資料夾中(部分原始碼蒐集於網路)
protected void Button1_Click(object sender, EventArgs e)
{
//原始碼是替換掉模板中的特徵字元

string mbPath =Server.MapPath("template.htm");
Encoding code
= Encoding.GetEncoding("gb2312");
StreamReader sr
= null;
StreamWriter sw
= null;
string str = null;
//讀取
try
{
sr
= new StreamReader(mbPath, code);
str
= sr.ReadToEnd();
}
catch (Exception ex)
{
throw ex;
}
finally
{
sr.Close();
}

//根據時間自動重新命名,副檔名也可以自行修改
string fileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".htm";
str
= str.Replace("$title$", txtTitle.Text);//替換Title
str = str.Replace("$content$", txtContent.Text);//替換content
//生成靜態檔案
try
{
sw
= new StreamWriter(Server.MapPath("htm/") + fileName, false, code);
sw.Write(str);
sw.Flush();

}
catch (Exception ex)
{
throw ex;
}
finally
{
sw.Close();
Response.Write(
"恭喜"+fileName+"已經生成,儲存在htm資料夾下!");
}
}
//根據Url地址生成靜態頁保持
protected void Button2_Click(object sender, EventArgs e)
{
Encoding code
= Encoding.GetEncoding("utf-8");
StreamReader sr
= null;
StreamWriter sw
= null;
string str = null;
//讀取遠端路徑
WebRequest temp = WebRequest.Create(txtUrl.Text.Trim());
WebResponse myTemp
= temp.GetResponse();
sr
= new StreamReader(myTemp.GetResponseStream(), code);
//讀取
try
{
sr
= new StreamReader(myTemp.GetResponseStream(), code);
str
= sr.ReadToEnd();
}
catch (Exception ex)
{
throw ex;
}
finally
{
sr.Close();
}
string fileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".html";
//寫入
try
{
sw
= new StreamWriter(Server.MapPath("htm/") + fileName, false, code);
sw.Write(str);
sw.Flush();
}
catch (Exception ex)
{
throw ex;
}
finally
{
sw.Close();
Response.Write(
"恭喜" + fileName + "已經生成,儲存在htm資料夾下!");
}
}
}
}
