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.htmlHTML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" "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"

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;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.Data.SqlClient;

using System.IO;

public partial class newOperate_aspxTohtml : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

        this.Button5.Attributes.Add("Onclick", "window.close();"); //在本地关闭当前页,而不需要发送到服务器去关闭当前页时

        if (!Page.IsPostBack)

        {

            //自动检索二级类

            SqlConnection con = db.createconnection();

            con.Open();

            SqlCommand cmd = new SqlCommand("select classID_2,classname from Menulclass_2 where classID=1", con);

            SqlDataReader sdr = cmd.ExecuteReader();

            this.ddlnewclass2.DataSource = sdr;

            this.ddlnewclass2.DataTextField = "classname";

            this.ddlnewclass2.DataValueField = "classID_2";

            //classID_b = (int)(this.ddlnewclass2.DataValueField);

            this.ddlnewclass2.DataBind();

            con.Close();

            //自动检索三级类

            SqlConnection con1 = db.createconnection();

            con1.Open();

            SqlCommand cmd1 = new SqlCommand("select classID_3,classname from Menulclass_3 where classID_2=11", con1);

            SqlDataReader sdr1 = cmd1.ExecuteReader();

            this.ddlnewclass3.DataSource = sdr1;

            this.ddlnewclass3.DataTextField = "classname";

            this.ddlnewclass3.DataValueField = "classID_3";

            this.ddlnewclass3.DataBind();

            con1.Close();

        }

   }

    protected void ddlnewclass_SelectedIndexChanged(object sender, EventArgs e)

    {

        //当选择了大类按钮,则自动填充小类的内容

        this.ddlnewclass2.Items.Clear();

        SqlConnection con = db.createconnection();

        con.Open();

        //Response.Write(this.ddlnewclass.SelectedItem.Value);

        SqlCommand cmd = new SqlCommand("select classID_2,classname from Menulclass_2 where classID=" + this.ddlnewclass1.SelectedValue, con);

        SqlDataReader sdr = cmd.ExecuteReader();

        this.ddlnewclass2.DataSource = sdr;

        this.ddlnewclass2.DataTextField = "classname";

        this.ddlnewclass2.DataValueField = "classID_2";

        this.ddlnewclass2.DataBind();

        con.Close();

        //自动填充三级类的内容

        this.ddlnewclass3.Items.Clear();

        SqlConnection conn = db.createconnection();

        conn.Open();

        SqlCommand cmdn = new SqlCommand("select classID_3,classname from Menulclass_3 where classID_2=" + this.ddlnewclass2.SelectedValue, conn);

        SqlDataReader sdrn = cmdn.ExecuteReader();

        this.ddlnewclass3.DataSource = sdrn;

        this.ddlnewclass3.DataTextField = "classname";

        this.ddlnewclass3.DataValueField = "classID_3";

        this.ddlnewclass3.DataBind();

        conn.Close();

    }

    protected void ddlnewclass2_SelectedIndexChanged(object sender, EventArgs e)

    {

        //当选择了小类按钮,则自动填充三级类的内容

        this.ddlnewclass3.Items.Clear();

        SqlConnection conn = db.createconnection();

        conn.Open();

        //Response.Write(this.ddlnewclass2.SelectedItem.Value);

        SqlCommand cmdn = new SqlCommand("select classID_3,classname from Menulclass_3 where classID_2=" + this.ddlnewclass2.SelectedValue, conn);

        SqlDataReader sdrn = cmdn.ExecuteReader();

        this.ddlnewclass3.DataSource = sdrn;

        this.ddlnewclass3.DataTextField = "classname";

        this.ddlnewclass3.DataValueField = "classID_3";

        this.ddlnewclass3.DataBind();

        conn.Close();

    }

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。
