asp批量转换文件编码(只把汉字转换成utf8)
''编写目的：批量转换asp文件编码，只转换汉字，wap开发用;
''特别提示：请建立新的网站放在根目录下使用，切勿在虚拟目录中使用;server支持fso
''使用前说明：把代码复制保存为gb-utf.asp,放在web文件夹根目录下面,在web根目录下面新建utf8文件夹(存放转换后的web文件);一切完成后访问运行gb-uft.asp即可；如我本机是http://127.0.0.1/gb-utf.asp;

gb-utf.asp文件内内容为：


timeStart = now()''页面开始执行时间

set fileSysObj = CreateObject("Scripting.FileSystemObject")''建立fso对象
set f = fileSysObj.GetFolder(server.MapPath("/"))


''检查是否存在输出的根目录
if not fileSysObj.folderexists(server.MapPath("/")) then
fileSysObj.CreateFolder(server.MapPath("/utf8"))
end if


''遍历根目录下面的文件，除了gb-utf.asp文件
response.Write "=====================转换文件清单如下======================="
set ffl = f.files
for each fil in ffl
if fil.name <> "gb-utf.asp" then
if right(fil.name,3) = "asp" then
call gb2312_utf8("",fil.name)
else
call CopyFiles("",fil.name)
end if
response.Write fil.name&""
end if
next


''遍历各个子目录下的文件，除了uft8文件夹
set fc = f.SubFolders
for each f1 in fc
if f1.name <> "utf8" then
Set folders = fileSysObj.GetFolder(server.MapPath("/"&f1.name))
set fss = folders.files
for each fls in fss
if right(fls.name,3) = "asp" then
call gb2312_utf8(f1.name,fls.name)
else
call CopyFiles(f1.name,fls.name)
end if
response.Write f1.name&"/"&fls.name&""
next
end if
next
response.Write "====================="&now()&"======================="
response.Write "=====================耗时："&cstr(round(cdbl((now()-timeStart)*24*60*60),4))&"秒======================="
