Five options on how to generate static pages

Option 1: 

/// <summary>
/// 传入URL返回网页的html代码
/// </summary>
/// <param name="Url">URL</param>
/// <returns></returns>
public static  string getUrltoHtml(string Url)
{
errorMsg = "";
try
{
System.Net.WebRequest wReq = System.Net.WebRequest.Create(Url);
// Get the response instance.
System.Net.WebResponse wResp =wReq.GetResponse();
// Read an HTTP-specific property
//if (wResp.GetType() ==HttpWebResponse)
//{
//DateTime updated  =((System.Net.HttpWebResponse)wResp).LastModified;
//}
// Get the response stream.
System.IO.Stream respStream  = wResp.GetResponseStream();
// Dim reader As StreamReader = New StreamReader(respStream)
System.IO.StreamReader reader = new System.IO.StreamReader(respStream, System.Text.Encoding.GetEncoding("gb2312"));
return  reader.ReadToEnd();

}
catch(System.Exception ex)
{
errorMsg = ex.Message ;
}
return "";
}

You can use this function to get the client-side html code of the webpage, and then save it to a .html file.

Option 2:

It is not difficult to generate a single static page. What is difficult is how to keep the associations and links between each static page intact; especially when pages are frequently updated, modified, or deleted;

Like Alibaba The pages are all in html. It is estimated that the address mapping function is used. For address mapping, please refer to: http://www.easewe.com/Article/ShowArticle.aspx?article=131

You can take a look at this page and analyze it. Check out his "bidding countdown" function http://info.china.alibaba.com/news/subject/v1-s5011580.html?head=top4&Bidding=home5

ASP.Net generates static HTML pages
implemented in Asp FileSystemObject object used to generate static pages!
In .Net, such operations are involved in System.IO
The following is the program code Note: This code is not original! Refer to other people’s code

//生成HTML页
  public static bool WriteFile(string strText,string strContent,string strAuthor)
  {
   string path = HttpContext.Current.Server.MapPath("/news/");
   Encoding code = Encoding.GetEncoding("gb2312");
   // 读取模板文件
   string temp = HttpContext.Current.Server.MapPath("/news/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";
   // 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;

此函数放在Conn.CS基类中了在添加新闻的代码中引用 注：工程名为Hover

    if(Hover.Conn.WriteFilethis.Title.Text.ToString),this.Content.Text.ToString),this.Author.Text.ToString)))
    {
     Response.Write("添加成功");
    }
    else
    {
     Response.Write("生成HTML出错!");
    }

Template page Text.html code

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
  <title>ShowArticle</title>
   <body>
biaoti
<br>
content<br>
author
</body>
</HTML>
biaoti
<br>
content<br>
author
</body>
</HTML>

After the prompt is added successfully, an html file with the current time as the file name will appear! The above just writes the passed parameters directly into the HTML file. In actual applications, you need to add the database first and then write the HTML file

Option 3: Give an example for client reference (SJ)

Its function is to obtain the code of a certain page in the client's way, and then it can be used for other purposes. This example is to directly output 

<script>
    var oXmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
    oXmlHttp.open("GET","http://www.webjx.com", false);
    oXmlHttp.send()
    var oStream = new ActiveXObject("ADODB.Stream");
    if(oStream == null)
        alert("您的机器不支持ADODB.Stream.")
    else
    {
        oStream.Type=1;
        oStream.Mode=3;
        oStream.Open() ;
        oStream.Write(oXmlHttp.responseBody);
        oStream.Position= 0;
        oStream.Type= 2;
        oStream.Charset="gb2312";
        var result= oStream.ReadText();
        oStream.Close();
        oStream = null;
        var aa = window.open("","")
        document.write(result);
        aa.document.write(result);
    }
</script>

Option 4: Learn csdn Same. Use xml to save data, and the template XSL only has one file.

Use xml to save data, use xsl to define templates and generate data. Data can be easily displayed on the client or service segment through xsl. If you want to generate a static leaf surface, it is even simpler. Go check and solve the problem of .net xml class package.

Advantages: It can be easily and quickly converted into the format and content you want.
Disadvantages: Need to learn more content, difficult to get started.

Option 5:

Idea 1:

1. Use tools like

to generate templates in html format, add special tags (such as $htmlformat$) where formatting needs to be added, and use code reading when dynamically generating files Get this template, then get the content input by the front desk, add it to the marked position of this template, generate a new file name and write it to the disk, and then write the relevant data to the database.
2. Use the background code to hardcode the Html file. You can use the HtmlTextWriter class to write the html file.

Advantages:

1. You can create very complex pages by using the method of including js files and adding the document.write() method in the js files to add content such as page headers, advertisements, etc. to all pages.

2. Static html files can use the Index Server of MS Windows2000 to build a full-text search engine, and use asp.net to obtain search results in the form of DataTable. The Index service of Win2000 cannot find the contents of the xml file. If it includes database search and Index index dual search, then this search function will be very powerful.

3. Save server load. Requesting a static html file saves many server resources than an aspx file.

Disadvantages:

Idea 2: If you use hard coding, the workload will be very large and a lot of html code will be required. Debugging is difficult. Moreover, the HTML style generated using hard coding cannot be modified. If the website changes the style, it must be recoded, which will bring a huge workload in the later stage.

So the first idea is adopted here

Show code

1. Define (template.htm) html template page

<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<body >
<table $htmlformat[0] height="100%" border="0" width="100%" cellpadding="10" cellspacing ="0" bgcolor="#eeeeee" style="border:1px solid #000000">
<tr>
<td width="100%" valign="middle" align="left">
<span style="color: $htmlformat[1];font-size: $htmlformat[2]">$htmlformat[3]</span>
</td>
</tr>
</table>
</body>
</html>

2.asp.net code:

//---------------------读html模板页面到stringbuilder对象里----

string[] format=new string[4];//定义和htmlyem标记数目一致的数组
StringBuilder htmltext=new StringBuilder();
try
{
    using (StreamReader sr = new StreamReader("存放模板页面的路径和页面名"))
    {
        String line;
        while ((line = sr.ReadLine()) != null)
        {
            htmltext.Append(line);
        }
        sr.Close();
    }

catch
{
    Response.Write("＜Script＞alert(&#39;读取文件错误&#39;)＜/Script＞");

//---------------------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("存放路径和页面名",false,System.Text.Encoding.GetEncoding("GB2312")))    
    {
        sw.WriteLine(htmltext);
        sw.Flush();
        sw.Close();
    }
}
catch
{
    Response.Write ("The file could not be wirte:");
}

Summary
This method can be convenient Generate html files. The program uses loop replacement, so it is very fast for templates that need to replace a large number of elements.
