接下来,我们要在process.asp中对从浏览器中获取的数据进行必要的处理,因为我们在process.asp中获取到的数据不仅仅包含了我们想要的上传上来的图片的数据,也包含了其他的无用的信息,我们需要剔除冗余数据,并将处理过的图片数据保存到数据库中,这里我们以Access97为例。具体代码如下(process.asp):
< %
response.buffer=true
formsize=request.totalbytes
formdata=request.binaryread(formsize)
bncrlf=chrB(13) & chrB(10)
divider=leftB(formdata,clng(instrb(formdata,bncrlf))-1)
datastart=instrb(formdata,bncrlf & bncrlf)+4
dataend=instrb(datastart+1,formdata,divider)-datastart
mydata=midb(formdata,datastart,dataend)
set connGraph=server.CreateObject("ADODB.connection")
connGraph.ConnectionString="driver={Microsoft
Access Driver (*.mdb)};DBQ=" &
server.MapPath("images.mdb") & ";uid=;PWD=;"
connGraph.Open
set rec=server.createobject("ADODB.recordset")
rec.Open "SELECT * FROM [images] where id is
null",connGraph,1,3
rec.addnew
rec("img").appendchunk mydata
rec.update
rec.close
set rec=nothing
set connGraph=nothing
