远程引用163网易相册的照片

例如你的163相册里有张图片地址是
http://img405.photo.163.com/linxi790504/48619570/1292870419.jpg

如果直接在其他网站或者论坛的贴图框框的地址里填
http://img405.photo.163.com/linxi790504/48619570/1292870419.jpg

这样发出来，肯定显示红叉叉。但只要在图片地址前面加上
http://www.jiangyao.com/163.asp?url=

即，贴图图片的地址中填
http://www.jiangyao.com/163.asp?url=http://img405.photo.163.com/linxi790504/48619570/1292870419.jpg

OK 大功告成，你的网易相册中的图片就可以显示在其他网站了

请看图一：

该图地址为：http://img405.photo.163.com/linxi790504/48619570/1292870419.jpg

请看图二：
该图地址为：http://www.jiangyao.com/163.asp?url=http://img405.photo.163.com/linxi790504/48619570/1292870419.jpg

这个图同理

如果你希望你的网站也有这个功能,代码如下:

asp:

<%
Dim url, body, myCache

url = Request.QueryString("url")

Set myCache = new cache
myCache.name = "picindex"&url
If myCache.valid Then
body = myCache.value
Else
body = GetWebData(url)
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

'取得数据
Public Function GetWebData(ByVal strUrl)
Dim curlpath
curlpath = Mid(strUrl,1,Instr(8,strUrl,"/"))
Dim Retrieval
Set Retrieval = Server.CreateObject("Microsoft.XMLHTTP")
With Retrieval
.Open "Get", strUrl, False,"",""
.setRequestHeader "Referer", curlpath
.Send
GetWebData =.ResponseBody
End With
Set Retrieval = Nothing
End Function
