我一直使用下面的脚本来上传文件在经典的asp,但它停止工作,给我这个错误
vbscript运行时错误800a01a8
对象所需的'Item(...)‘
我做了一些调查,我认为问题出在包含BuildUploadRequest函数的文件upload.asp中,但我真的不明白原因
表格
<form method="POST" action="landing-page.asp" ENCTYPE="multipart/form-data">
<input type="file" name="file">
<input type="hidden" name="key" value="0">
<input type="submit" name="send" value="1">
</form>

Dim UploadRequest
Set UploadRequest = CreateObject("Scripting.Dictionary")
BuildUploadRequest(RequestBin) '//function defined in upload.asp
if UploadRequest.Item("key").Item("Value")="0" then '//this is the line giving the error
'//code here...
end if

PosBeg = 1
PosEnd = InstrB(PosBeg,RequestBin,getByteString(chr(13)))

End Sub
'//String to byte string conversion
Function getByteString(StringStr)
For i = 1 to Len(StringStr)
charx = Mid(StringStr,i,1)
getByteString = getByteString & chrB(AscB(charx))
Next
End Function
'//Byte string to string conversion
Function getString(StringBin)
getString =""

End Function
这段代码在每个项目中都能正常工作,但现在并不是所有地方都能正常工作。所以我不能只是编辑和使用另一个函数,我需要理解为什么它不再工作了
