.NET生成静态页面的方案总结

2011-01-25 17:09 393 查看

方法一：在服务器上指定aspx网页，生成html静态页1;
/// <summary>
/// 在服务器上指定aspx网页，生成html静态页1;
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Button1_Click(object sender, EventArgs e)
{
System.IO.StreamWriter sw = new System.IO.StreamWriter(Server.MapPath("静态页面.html"), false, System.Text.Encoding.GetEncoding("gb2312"));
System.Web.HttpContext.Current.Server.Execute("Login_Admin.aspx", sw);
sw.Close();
}

方法二：从指定连接获取源代码生成html静态页2。其实这应该算网页源代码获取方式了。
/// <summary>
/// 从指定连接获取源代码生成html静态页2。其实这应该算网页源代码获取方式了。
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Button2_Click(object sender, EventArgs e)
{
string pageurl = "http://www.baidu.com/";
System.Net.WebRequest request = WebRequest.Create(pageurl);
WebResponse response = request.GetResponse();
Stream resstream = response.GetResponseStream();
StreamReader sr = new StreamReader(resstream, System.Text.Encoding.Default);
string contenthtml = sr.ReadToEnd();
resstream.Close();
sr.Close();//写入文件
System.IO.StreamWriter sw;
sw = new System.IO.StreamWriter(Server.MapPath("静态页2.htm"), false, System.Text.Encoding.Default);
sw.Write(contenthtml);
sw.Close();
}
方法三： 在服务器上执行aspx网页时在Page_Render事件里将本页面生成html静态页3;
/// <summary>
/// 在服务器上执行aspx网页时在Page_Render事件里将本页面生成html静态页3;
/// </summary>
/// <param name="writer"></param>
protected override void Render(HtmlTextWriter writer)
{
System.IO.StringWriter html = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter tw = new System.Web.UI.HtmlTextWriter(html);
base.Render(tw);
System.IO.StreamWriter sw;
sw = new System.IO.StreamWriter(Server.MapPath("静态页3.htm"), false, System.Text.Encoding.Default);
sw.Write(html.ToString());
sw.Close();
tw.Close();
Response.Write(html.ToString());
}
方法四：根据已有模板页生成一个页面（用于生成静态新闻页面）
/// <summary>
/// 生成静态新闻页面
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Button3_Click(object sender, EventArgs e)
{
if (WriteFile("标题", "内容", "author"))
{
Response.Write("对了。。。呵呵");
}
else
{
RegisterStartupScript("", "<mce:script type="text/javascript"><!--
alert('错了')
// --></mce:script>");
}
}
//生成HTML页
public static bool WriteFile(string strText, string strContent, string strAuthor)
{
string path = HttpContext.Current.Server.MapPath("CSS");
Encoding code = Encoding.GetEncoding("gb2312");
// 读取模板文件
string temp = HttpContext.Current.Server.MapPath("text.html");
StreamReader sr = null;
StreamWriter sw = null;
string str = "";
try
{
sr = new StreamReader(temp, code);
str = sr.ReadToEnd(); // 读取文件
}
catch (Exception exp)
{
HttpContext.Current.Response.Write(exp.Message);
HttpContext.Current.Response.End();
sr.Close();
}
string htmlfilename = DateTime.Now.ToString("yyyyMMddHHmmss") + ".html";//文件名字
// 替换内容
// 这时,模板文件已经读入到名称为str的变量中了
str = str.Replace("ShowArticle", strText); //模板页中的ShowArticle
str = str.Replace("biaoti", strText);
str = str.Replace("content", strContent);
str = str.Replace("author", strAuthor);
// 写文件
try
{
sw = new StreamWriter(path + htmlfilename, false, code);
sw.Write(str);
sw.Flush();
}
catch (Exception ex)
{
HttpContext.Current.Response.Write(ex.Message);
HttpContext.Current.Response.End();
}
finally
{
sw.Close();
}
return true;
}
/***********************text.html页面*********************************/
<html>
<head>
<title>ShowArticle</title>
</head>
<body>
biaoti
<br />
content
<br />
author
</body>
</html>
方法五：根据特殊标记(如$htmlformat$),动态生成文件时利用代码读取此模板
/// <summary>
/// 在需要添加格式的地方加入特殊标记(如$htmlformat$),动态生成文件时利用代码读取此模板，然后获得前台输入的内容，添加到此模板的标记位置中，生成新文件名后写入磁盘，写入后再向数据库中写入相关数据。
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void Button4_Click(object sender, EventArgs e)
{
string[] format = new string[4];//定义和htmlyem标记数目一致的数组
StringBuilder htmltext = new StringBuilder();
using (StreamReader sr = new StreamReader("Web/template.htm"))
{
String line;
while ((line = sr.ReadLine()) != null)
{
htmltext.Append(line);
}
sr.Close();
}
//---------------------给标记数组赋值------------
format[0] = "background='/blog/bg.jpg'";//背景图片
format[1] = "#990099";//字体颜色
format[2] = "150px";//字体大小
format[3] = "<marquee>生成的模板html页面</marquee>";//文字说
//----------替换htm里的标记为你想加的内容
for (int i = 0; i < 4; i++)
{
htmltext.Replace("$htmlformat[" + i + "]", format[i]);
}
//----------生成htm文件------------------――
try
{
using (StreamWriter sw = new StreamWriter("Web/News/a.htm", false, System.Text.Encoding.GetEncoding("GB2312")))
{
sw.WriteLine(htmltext);
sw.Flush();
sw.Close();
}
}
catch
{
Response.Write("The file could not be wirte:");
}
}
/*******************template.htm页面**********************/
<!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>无标题页</title>
</head>
<body>
<table $htmlformat[0] height="100%" border="0" width="100%" cellpadding="10" cellspacing ="0" bgcolor="#eeeeee" style="border:1px solid #000000" mce_style="border:1px solid #000000">
<tr>
<td width="100%" valign="middle" align="left">

</td>
</tr>
</table>
</body>
</html>

静态页面的分页。。。

主要的原理就是替换模板里的特殊字符。

1、静态模板页面 template.html，主要是定义了一些特殊字符，用来被替换。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>$Title</title>
</head>
<body>
<div style="width: 417px; height: 54px" align="center">
<br />
$Title</div>
<div style="width: 417px; height: 8px">
浏览<font color="red"><script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=$NewsId"></script></font>次 $Time</div>
<div style="width: 417px; height: 100px">
$Content</div>
<div style="width: 416px; height: 9px">
$Pager</div>
<div style="width: 416px; height: 8px">
<form id="form1" action="../AddComment.aspx" style="margin:0px">
<input id="Text1" type="text" /><Img id="Image1" src="../../UserInfo/CheckCode.aspx"/><br />
<textarea id="CommentContent" cols="20" rows="2"></textarea>
<br />
<input id="NewsId" type="hidden" value="$NewsId"/>
<input id="Button1" type="submit" value="button" />
<a href="../Display.aspx?NewsId=$NewsId">查看更多评论</a></form>
</div>
</body>
</html>

2、前态页面 NewsAdd.aspx，就是一个表单，用来填写新闻的标题和内容。

<%@ Page Language="C#" AutoEventWireup="false" validateRequest="false" CodeFile="NewsAdd.aspx.cs" Inherits="NewsAdd.Admin_AdminPanel_NewsAdd" %>
<%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %>
<!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>添加新闻</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="Label2" runat="server" Text="标题"></asp:Label>
<asp:TextBox ID="Title" runat="server" Width="325px"></asp:TextBox><br />
<asp:Label ID="Label1" runat="server" Text="内容"></asp:Label>
<FCKeditorV2:FCKeditor id="Content" basePath="~/FCKeditor/" runat="server" Height="400px" Width="70%"></FCKeditorV2:FCKeditor>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
<asp:Label ID="Message" runat="server" ></asp:Label></div>
</form>
</body>
</html>

3、后台页面 NewsAdd.aspx.cs
