ASP.Net自动批量生成HTML页面和索引页
ASP.Net自动批量生成HTML页面和索引页
(泰州市国土资源局,江苏 泰州 225300)
2007.6.5
前天在园子里把在ASP.net中网站访问量统计方法 一文贴了上去,觉得对刚学做网站的朋友还有点用处,也有好多朋友留言鼓励,也有朋友指出了存在的问题,对我很受启发。今天是休息日,我就把在“独上高楼”网站上原创一这篇文章又贴了上来,敬请朋友指教,本文是参考了大型网站新闻系统如何生成静态网页、ASP.NET生成静态网页的方法 等文章后形成的思路,同时在本人网站上实现了批量转换。以下所发布的代码均为我个人网站实际运行的代码,读者可以作适当的修改后相信能在你的系统中运行。
本网站新闻分类为三级,即大类、小类、三级类,主页面为VS.net动态页面,要实现一次性自动批量生成HTML页面和索引页面,需要解决如下问题:
1.在添加和修改文章时,自动生成HTML页面;
2.根据新闻分类自动判断和创建存储HTML页面的目录;
3.按三级类、小类、大类自动批量生成HTML页面,或者一次性生成所有的HTML页面和HTML索引页面;
一、根据新闻分类自动判断和创建存储HTML页面的目录
在添加和修改新闻时,需要对新闻所属类别进行选择或者确认,本网站就是根据新闻三级分类来创建存储HTML页面目录的,所有索引目录存储在“HTML”目录下,所有HTML文件存储在对应的第三级目录下,如123.html存储在:../ntml/1/11/111/123.html。HTML文件名均采用文章的ID编号命名。
自动判断和创建存储HTML页面的目录的代码如下,解释包含在代码中,这里不重复了:
//这里自动生成Html文件
//首先判断是否要创建按照ID三级文件夹
string ClassPathA = this.txtClass1.Text.Trim(); // ClassPathA为大类码
string ClassPathB = this.txtClass2.Text.Trim(); // ClassPathB为小类码
string ClassPathC = this.txtClass3.Text.Trim(); // ClassPathC为三级类码
string news_ClassPath = "html/" + ClassPathA + "/" + ClassPathB + "/" + ClassPathC + "/";
//HttpContext.Current.Server.MapPath(相对路径):把相对路径转为服务器上的绝对路径。File.Exists(绝对路径):检查是否存在绝对路径指向的文件或目录。
if (!File.Exists(HttpContext.Current.Server.MapPath("html/") + ClassPathA))
{
//System.IO.Directory.CreateDirectory(文件夹绝对路径):建立绝对路径文件夹。
System.IO.Directory.CreateDirectory(@HttpContext.Current.Server.MapPath("html/") + """" + ClassPathA);
}
if (!File.Exists(HttpContext.Current.Server.MapPath("html/" + ClassPathA) + ClassPathB))
{
System.IO.Directory.CreateDirectory(@HttpContext.Current.Server.MapPath("html/" + ClassPathA) + """" + ClassPathB);
}
if (!File.Exists(HttpContext.Current.Server.MapPath("html/" + ClassPathA + "/" + ClassPathB) + ClassPathC))
{
System.IO.Directory.CreateDirectory(@HttpContext.Current.Server.MapPath("html/" + ClassPathA + "/" + ClassPathB) + """" + ClassPathC);
}
二、在添加和修改文章时,自动生成HTML文件
在添加和修改新闻文章时,可以生动生成HTML页面,也可以留待以后生成。本网站在添加或者修改一篇文章后是自动生成HTML页面的,代码如下:
//自动生成Html文件
string news_title=this.txtTitle.Text;
string strBody = Server.HtmlDecode(this.FreeTextBox1.Text.Trim());
strBody = strBody.Replace(System.Web.HttpUtility.HtmlDecode(" "), " "); //去掉代替空格显示的“?”号
string news_Body = strBody;
string news_id=Request.QueryString["articleID_int"].ToString();
string news_Writer=this.txtWriter.Text;
string news_Source = this.txtsource.Text;
string news_Dateantime = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
bool result = HtmlDB.WriteFile_1(news_title, news_Body, news_id, news_Writer, news_Source, news_Dateantime, news_ClassPath);
if (result)
{
Response.Write("〈script〉alert(""生成HTML页面成功"");〈/script〉");
}
else
{
}
这里的关键是黑体字部分,因为需要把HtmlDecode中的一些如" "符号转换为空格,还有一些不明不白的符号,我也弄不清楚,必需要转换一下,修改时从数据库中读取也是一样需要转换。其他的代码相信大家能看懂的。
三、自动批量生成HTML页面和索引页
需要说明的是,本程序首先由新闻数据库创建了一个强类型的DataSet,以下代码均针对强类型数据集进行操作,关于强类型数据集不在本文论讨的范围之内,你可以在这里得到有关创建数据访问层和强类型的知识(http://whx.tzgt.gov.cn/newshow/newBodyShow.aspx?articleID=688),里不加表述。如果对强类型数据集不熟悉,也可以直接对数据库进行操作以获取数据。
1.创建一个HTML页面模板
创建一个名为HtmlModule.htm模板,用以统一所生成的HTML页面的格式,创建一个名叫HtmlModuleAllNews.htm的模板页面,用于生成索引页面。在创建HTML页面时系统实际上是读取该模板,然后添加替换有关内容后而生成HTML页面的。关于HTML页面模板你可以自己做一个HTML页面,由于我的HtmlModule.htm模板代码较大,所以用索引页面的模板HtmlModuleAllNews.htm示出:
〈!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〉{txtTitle}〈/title〉
〈meta http-equiv="Content-Type" content="text/html; charset=gb2312" /〉
〈/head〉
〈body〉

〈tr〉

注意,加黑地方的{txtTitle}、{content}就是需要替换的内容。
2.创建一个自动生成Html页面的的公共类
创建一个名叫HtmlDB.cs的公共类,它的作用主要是生成Html页面和索引页面。其类代码如下:
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.Text;
using System.IO;
///
/// DB 的摘要说明
///
public class HtmlDB
{
public HtmlDB()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
//以下WriteFile_1()用于生成HTML页面
public static bool WriteFile_1(string news_title, string news_Body, string news_id, string news_Writer, string news_Source, string news_Dateantime, string news_ClassPath)
{
//申明字符编码,命名空间System.Text
Encoding encoding = Encoding.GetEncoding("gb2312");
//读取模板文件
string TemplatePath = HttpContext.Current.Server.MapPath("HtmlModule.htm"); //
//StreamReader实现一个 TextReader,使其以一种特定的编码从字节流中读取字符,命名空间System.IO。
StreamReader sr = null;
//StreamWriter实现一个 TextWriter,使其以一种特定的编码向流中写入字符,命名空间Syste.IO。
StreamWriter sw = null;
string str = "";
try
{
sr = new StreamReader(TemplatePath, encoding);
//从流的当前位置到末尾读取流
str = sr.ReadToEnd();
}
catch (Exception e1)
{
HttpContext.Current.Response.Write(e1.Message);
HttpContext.Current.Response.End();
}
finally
{
sr.Close();
sr.Dispose();
}
//生成路径
//string myPath = "html/";
string myPath = news_ClassPath;
string OutPutPath = HttpContext.Current.Server.MapPath(myPath);
//生成的文件名
//string newName = DateTime.Now.ToString("yyyyMM_") + news_id + ".html";
string newName = news_id + ".html";
//替换内容
str = str.Replace("{title}", news_title);
str = str.Replace("{content}", news_Body);
str = str.Replace("{txtTitle}", news_title);
str = str.Replace("{txtWriter}", news_Writer);
str = str.Replace("{txtSource}", news_Source);
str = str.Replace("{txtDateantime}", news_Dateantime);
//str = str.Replace("{newID}", news_id);
//写文件
try
{
sw = new StreamWriter(OutPutPath + newName,false, encoding);
sw.Write(str);
//清理当前编写器的所有缓存区,并将缓存数据写入基础流。
sw.Flush();
}
catch (Exception e2)
{
HttpContext.Current.Response.Write(e2.Message);
HttpContext.Current.Response.End();
}
finally
{
sw.Close();
sw.Dispose();
}
return true;
}
//以下WriteFileAllNew()用于生成HTML索引页
public static bool WriteFileAllNew(string fileTitle, string fileBody, string filePath, string FileName)
{
//申明字符编码,命名空间System.Text
Encoding encoding = Encoding.GetEncoding("gb2312");
//读取模板文件
string TemplatePath = HttpContext.Current.Server.MapPath("HtmlModuleAllNews.htm"); //
//StreamReader实现一个 TextReader,使其以一种特定的编码从字节流中读取字符,命名空间System.IO。
StreamReader sr = null;
//StreamWriter实现一个 TextWriter,使其以一种特定的编码向流中写入字符,命名空间Syste.IO。
StreamWriter sw = null;
string str = "";
try
{
sr = new StreamReader(TemplatePath, encoding);
//从流的当前位置到末尾读取流
str = sr.ReadToEnd();
}
catch (Exception e1)
{
HttpContext.Current.Response.Write(e1.Message);
HttpContext.Current.Response.End();
}
finally
{
sr.Close();
sr.Dispose();
}
//生成路径
//string myPath = "html/";
string myPath = filePath;
string OutPutPath = HttpContext.Current.Server.MapPath(myPath);
//生成的文件名
//string newName = DateTime.Now.ToString("yyyyMM_") + news_id + ".html";
string newName = FileName + ".html";
//替换内容
str = str.Replace("{txtTitle}", fileTitle);
str = str.Replace("{content}", fileBody);
//写文件
try
{
sw = new StreamWriter(OutPutPath + newName, false, encoding);
sw.Write(str);
//清理当前编写器的所有缓存区,并将缓存数据写入基础流。
sw.Flush();
}
catch (Exception e2)
{
HttpContext.Current.Response.Write(e2.Message);
HttpContext.Current.Response.End();
}
finally
{
sw.Close();
sw.Dispose();
}
return true;
}
}
以上代码主要有两个函数,一个是WriteFile_1()用于生成HTML页面,另一是WriteFileAllNew()用于生成HTML索引页。WriteFile_1()共有七个参数,其中:
news_title:用于替换HTML页面的标题;
news_Body:用于替换HTML页面的正文
news_id:为文章的ID号;
news_Writer:用于替换HTML页面的作者姓名;
news_Source:用于替换HTML页面的文章来源;
news_Dateantime:用于替换HTML页面的时间;
news_ClassPath:为存储HTML页面文件的路径;
关于WriteFileAllNew()参数基本与WriteFile_1()参数含义相似,不多叙述。
3.创建生成Html页的Web页面
本系统中将生成Html页的Web页面取名为aspxToHtml.aspx,页面视图如下,主要由三个DropDownList控件和五个Button控件组成,三个DropDownList控件用于选择新闻分类,五个Button控件用于选择自动生成的类型。如选择生成“大类”,则自动生成这一大类的所有Html页,并自动生成这一大类的索引页,以此类推。如果选择“全部”,则生成本网站的所有新闻的Html页,并生成一个总的索引页。
aspxToHtml.aspx页的后台代码如下:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;

}
}

{

HtmlDB.WriteFile_1(news_title, news_Body, news_id, news_Writer, news_Source, news_Dateantime, news_ClassPath); //生成每条新闻的网页文件
}
bool result = HtmlDB.WriteFileAllNew("独上高楼网站的所有文章", htmlBody, "html/", "allNews"); //生成新闻的链接页面文件

}
以上代码没什么很特别的地方,需要说明的是带黑体的代码,之前已经申明过,本系统采用了强类型数据集NewDataSet,所以对于数据的操作均是对数据集NewDataSet的操作。
htmlBody += " + htmlName + ""> + "dir='ltr' shape='rect' target='_blank'>" + htmlTitle + " + " " + NewRow_ALL.dateantime.ToString().Trim() + "
";"是历遍NewDataSet.MenulArticleRow行,取出文章内容。
以上代码朋友可以细细读来,相信你一定能读懂的。
