VB,VBS,实现server.URLEncode及反编码功能的函数URLEncode()与URLDecode()

Function URLEncode(strURL)
    Dim I
    Dim tempStr
    For I = 1 To Len(strURL)
        If Asc(Mid(strURL, I, 1)) < 0 Then
            tempStr = "%" & Right(CStr(Hex(Asc(Mid(strURL, I, 1)))), 2)
            tempStr = "%" & Left(CStr(Hex(Asc(Mid(strURL, I, 1)))), Len(CStr(Hex(Asc(Mid(strURL, I, 1))))) - 2) & tempStr
            URLEncode = URLEncode & tempStr
        ElseIf (Asc(Mid(strURL, I, 1)) >= 65 And Asc(Mid(strURL, I, 1)) <= 90) Or (Asc(Mid(strURL, I, 1)) >= 97 And Asc(Mid(strURL, I, 1)) <= 122) Or (Asc(Mid(strURL, I, 1)) >= 48 And Asc(Mid(strURL, I, 1)) <= 57) Then
            URLEncode = URLEncode & Mid(strURL, I, 1)
        Else
            URLEncode = URLEncode & "%" & Hex(Asc(Mid(strURL, I, 1)))
        End If
    Next
End Function

Function URLDecode(strURL)
    Dim I

    If InStr(strURL, "%") = 0 Then
        URLDecode = strURL
        Exit Function
    End If

    For I = 1 To Len(strURL)
        If Mid(strURL, I, 1) = "%" Then
            If Eval("&H" & Mid(strURL, I + 1, 2)) > 127 Then
                URLDecode = URLDecode & Chr(Eval("&H" & Mid(strURL, I + 1, 2) & Mid(strURL, I + 4, 2)))
                I = I + 5
            Else
