ASP實現頭像映像隨機變換

複製代碼 代碼如下:<%On Error Resume Next%>
<%
dim p, ppic, id, body, myCache
randomize
p=Int((3*rnd)+1)
id= Request.QueryString("id")
HttpUrl="http://sms.2e7.net/可愛卡通0"&p&".gif"
Set myCache = new cache
myCache.name = "picindex"&id
If myCache.valid Then
body = myCache.value
Else
body = GetWebData(HttpUrl)
myCache.add body,dateadd("d",1,now)
End If

If Err.Number = 0 Then
Response.CharSet = "UTF-8"
Response.ContentType = "application/octet-stream"
Response.BinaryWrite body
Response.Flush
Else
Wscript.Echo Err.Description
End if

'取得資料
