绝妙的asp生成html静态页面

随着网站访问量的加大，每次从数据库读取都是以效率作为代价的，很多用ACCESS作数据库的更会深有体会，静态页加在搜索时，也会被优先考虑。互联网上流行的做法是将数据源代码写入数据库再从数据库读取生成静态面，这样无形间就加大了数据库。将现有的ASP页直接生成静态页，将会节省很多。

　　下面的例子是将、index.asp?id=1/index.asp?id=2/index.asp?id=3/这三个动态页面，分别生成ndex1.htm,index2.htm,index3.htm存在根目录下面

<%
dim strUrl,Item_Classid,id,FileName,FilePath,Do_Url,Html_Temp
Html_Temp="<UL>"
For i=1 To 3
Html_Temp = Html_Temp&"<LI>"
Item_Classid = i
FileName = "Index"&Item_Classid&".htm"
FilePath = Server.MapPath("/")&"\"&FileName
Html_Temp = Html_Temp&FilePath&"</LI>"
Do_Url = "http://"
Do_Url = Do_Url&Request.ServerVariables("SERVER_NAME")&"/main/index.asp"
Do_Url = Do_Url&"?Item_Classid="&Item_Classid
strUrl = Do_Url
dim objXmlHttp
set objXmlHttp = Server.CreateObject("Microsoft.XMLHTTP")
objXmlHttp.open "GET",strUrl,false
objXmlHttp.send()
Dim binFileData
binFileData = objXmlHttp.responseBody
Dim objAdoStream
set objAdoStream = Server.CreateObject("ADODB.Stream")
objAdoStream.Type = 1
objAdoStream.Open()
objAdoStream.Write(binFileData)
objAdoStream.SaveToFile FilePath,2
objAdoStream.Close()
Next
Html_Temp = Html_Temp&"<UL>"
%>
<%
Response.Write ( "成功生成文件：" )
Response.Write ( "<BR>" )
Response.Write Html_Temp
%>

非摸板生成静态页

目前已经有很多生成html的新闻系统，但是都是用的模板，本函数实现把asp页面产生的html代码保存成为一个html文件，这样就没有必要改动原来的页面就可以轻松完成一个生成html的新闻系统了。^_^
由于代码比较短，这里就不进行注释了
<%
'当目标页面的包含文件即＃i nclude的页面里边存在response.End()的时候本程序有问题
'注意：本文件一定要放在filename指向的文件的同一目录下
dim hughchiu_rtcode
Function get_exe_code(filename)
dim execode
dim tmp_str
Dim re,re1,content,fso,f,aspStart,aspEnd
dim ms,m
execode = ""
set fso=CreateObject("Scripting.FileSystemObject")
set f=fso.OpenTextFile(server.mappath(filename))
content=f.ReadAll
f.close
set f=nothing
set fso=nothing

set re = new regexp
re.ignorecase = true
re.global = true
re.pattern = "\<\%\@[^\%]+\%\>"
content = re.replace(content,"")

re.global = false
re.pattern = "\<\!\-\-\s*\＃i nclude\s*file\s*=\s*\""([^\""]+)\""\s*\-\-\>"
do
set ms = re.execute(content)
if ms.count<>0 then
set m = ms(0)
tmp_str = get_exe_code(m.submatches(0))
content = re.replace(content, tmp_str)
else
exit do
end if
loop
set m = nothing
set ms = nothing

re.pattern="^\s*="
aspEnd=1
aspStart=inStr(aspEnd,content,"<%")+2

set re1=new RegExp
re1.ignorecase = true
re1.global = false
re1.pattern = "response\.Write(.+)"

do while aspStart>aspEnd+1
   execode = execode&vbcrlf&" hughchiu_rtcode = hughchiu_rtcode&"""&replace( replace(Mid(content,aspEnd,aspStart-aspEnd-2),"""",""""""), vbcrlf, """&vbcrlf&""")&""""&vbcrlf
   aspEnd=inStr(aspStart,content,"%\>")+2
   tmp_str = Mid(content,aspStart,aspEnd-aspStart-2)

do
set ms = re1.execute(tmp_str)
if ms.count<>0 then
set m = ms(0)
tmp_str = re1.replace(tmp_str, " hughchiu_rtcode = hughchiu_rtcode&"&m.submatches(0))
else
exit do
end if
loop

   set m = nothing
   set ms = nothing

   execode = execode& re.replace(tmp_str,"hughchiu_rtcode = hughchiu_rtcode&")

   aspStart=inStr(aspEnd,content,"<%")+2
loop

set re1 = nothing
set re=nothing

execode = execode&vbcrlf&" hughchiu_rtcode = hughchiu_rtcode&"""&replace( replace(Mid(content,aspEnd), """", """"""), vbcrlf, """&vbcrlf&""" )&""""&vbcrlf
get_exe_code = "<%"&execode&"%\>"
End Function

function asp2html(filename)
dim code
code = replace( replace( replace( get_exe_code(filename), "hughchiu_rtcode = hughchiu_rtcode&"""""&vbcrlf, "" ), "<%", "" ), "%\>", "" )
'response.Write(code)
execute(code)
'response.Write( hughchiu_rtcode )
asp2html = hughchiu_rtcode
end function
%>

使用范例：
set fso=CreateObject("Scripting.FileSystemObject")
set f=fso.CreateTextFile( server.mappath( "youpage.htm" ), true )
f.WriteLine( asp2html("youpage.asp") )
f.close
set f = nothing
set fso = nothing
