如何在VBA中用zlib解压Java中的字符串

Option Explicit

Sub DecompressString()
    Dim strCompressed As String

    Dim objZlib As New zlib.ZStream
    Dim objMemoryStream As New Scripting.Dictionary
    
    ' 假设strCompressed是从Java中传递过来的压缩字符串
    strCompressed = "压缩字符串"
    
    ' 将压缩字符串转换为字节数组
    Dim byteCompressed() As Byte
    byteCompressed = StrConv(strCompressed, vbFromUnicode)
    
    ' 初始化zlib解压缩对象
    objZlib.inflateInit
    
    ' 设置解压缩输入
    objZlib.next_in = VarPtr(byteCompressed(0))
    objZlib.avail_in = UBound(byteCompressed) + 1
    
    ' 解压缩数据
    Dim intBufferSize As Integer
    intBufferSize = 1024 ' 设置解压缩缓冲区大小
    Dim byteBuffer() As Byte
    ReDim byteBuffer(0 To intBufferSize - 1) As Byte
    
    Do
        objZlib.next_out = VarPtr(byteBuffer(0))
        objZlib.avail_out = intBufferSize
        
        objZlib.inflate zlib.Z_NO_FLUSH
        
        ' 将解压缩的数据存储到内存流中
        objMemoryStream.Add byteBuffer, objMemoryStream.Count
    Loop While objZlib.avail_out = 0
    
    ' 关闭zlib解压缩对象
    objZlib.inflateEnd
    
    ' 将解压缩的数据转换为字符串
    Dim i As Integer
    For i = 0 To objMemoryStream.Count - 1
        strDecompressed = strDecompressed & StrConv(objMemoryStream(i), vbUnicode)
    Next i
    
    ' 输出解压缩后的字符串
    Debug.Print strDecompressed
End Sub
