我编写了一个小型 VBScript 类，用于处理以这种格式编写的“真实”ini 文件：
[section_name]
key1 = value1
key2 = value2
该类的代码是：
Class IniFileObject
Private m_Data
Private Sub Class_Initialize
Set m_Data = Server.CreateObject("Scripting.Dictionary")
End Sub
Private Sub Class_Terminate
Dim key
If IsObject(m_Data) Then
For Each key In m_Data
m_Data(key).RemoveAll
Set m_Data(key) = Nothing
Next
m_Data.RemoveAll
Set m_Data = Nothing
End If
End Sub
Public Function Init(sFilePath)
Dim arrLines, sLine, x
Dim sCurSection, oSectionDict
Set Init = Me
arrLines = GetFileLines(sFilePath)
If Not(IsArray(arrLines)) Then Exit Function
sCurSection = ""
For x = 0 To UBound(arrLines)
sLine = Trim(arrLines(x))
If Len(sLine)>0 Then
If Left(sLine, 1)="[" Then
If Not(HandleSectionLine(sLine, sCurSection)) Then Exit Function
Else
If Len(sCurSection)=0 Then
Err.Raise 1005, "IniFileObject init", "Found value outside any section (" & Server.HTMLEncode(sLine) & ")"
Exit Function
End If
Set oSectionDict = m_Data(sCurSection)
If Not(ParseOneLine(sLine, oSectionDict)) Then Exit Function
Set m_Data(sCurSection) = oSectionDict
End If
End If
Next
End Function
Public Property Get ReadValue(section, key)
Dim oSectionDict
ReadValue = ""
If m_Data.Exists(section) Then
Set oSectionDict = m_Data(section)
If oSectionDict.Exists(key) Then ReadValue = oSectionDict(key)
End If
End Property
Private Function ParseOneLine(ByVal sLine, ByRef oSectionDict)
Dim arrTemp, sErrorMsg, sKey
sErrorMsg = ""
ParseOneLine = True
If Left(sLine, 2)="//" Or Left(sLine, 1)="'" Or Left(sLine, 1)="{" Then Exit Function
arrTemp = Split(sLine, "=")
If UBound(arrTemp)=1 Then
sKey = Trim(arrTemp(0))
If (Len(sKey)>0) And (Len(arrTemp(1))>0) Then
If Not(oSectionDict.Exists(sKey)) Then
oSectionDict.Add sKey, Trim(arrTemp(1))
Else
sErrorMsg = "Key already exists"
End If
Else
sErrorMsg = "Empty key or value"
End If
Else
sErrorMsg = "Missing or too much '=' characters"
End If
Erase arrTemp
If Len(sErrorMsg)>0 Then
ParseOneLine = False
Err.Raise 1006, "IniFileObject Init", "Failed to parse single line (" & Server.HTMLEncode(sLine) & "): " & sErrorMsg
End If
End Function
Private Function HandleSectionLine(ByVal sLine, ByRef sCurSection)
HandleSectionLine = False
If (Len(sLine)<3) Or (Right(sLine, 1)<>"]") Then
Err.Raise 1002, "IniFileObject init", "Invalid line found: " & Server.HTMLEncode(sLine)
Exit Function
End If
sCurSection = Mid(sLine, 2, Len(sLine) - 2)
If m_Data.Exists(sCurSection) Then
Err.Raise 1003, "IniFileObject init", "Section exists more than once: " & Server.HTMLEncode(sCurSection)
Exit Function
End If
m_Data.Add sCurSection, Server.CreateObject("Scripting.Dictionary")
HandleSectionLine = True
End Function
Private Function GetFileLines(sFilePath)
Dim objFSO, oFile
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
If Not(objFSO.FileExists(sFilePath)) Then
Set objFSO = Nothing
Err.Raise 1001, "IniFileObject init", "file path '" & Server.HTMLEncode(sFilePath) & "' does not exist, check permissions"
Exit Function
End If
Set oFile = objFSO.OpenTextFile(sFilePath)
GetFileLines = Split(oFile.ReadAll, VBCrLf)
oFile.Close
Set oFile = Nothing
Set objFSO = Nothing
End Function
End Class
使用示例：
Dim filePath, ini
filePath = Server.MapPath("config.ini")
Set ini = New IniFileObject.Init(filePath)
Response.Write("Value for 'Key001': " & ini.ReadValue("MySection", "Key001") & "<br />")
Set ini = Nothing
当文件不存在或包含无效行时，代码会抛出各种错误，这些错误非常明显。可以在使用时使用这样的代码来“抑制”错误并且不显示错误页面：
On Error Resume Next
Set ini = New IniFileObject.Init(filePath)
If Err.Number<>0 Then
Response.Write("Error reading ini file")
End If
On Error Goto 0
If IsObject(ini) Then
Response.Write("Value for 'IP001': " & ini.ReadValue("IPaddress", "IP001") & "<br />")
Set ini = Nothing
End If
