【散分】怎样用VB把汉字转为URI编码【已解决】

DawnPine 2012-08-22 06:41:14

在URL地址中，一个汉字用 %XX%YY%ZZ 来表示，查了一下，好像这个是叫URI编码
求把汉字转为URI编码的办法。
如果在VBA中调用这个办法，需要引用哪些东西。
谢谢！

Function UTF8EncodeURI(strUTF8 As String) As String

    Dim nFor    As Long

    Dim nAsc    As Long

    Dim strWchar    As String

    Dim strURIchar  As String

    

    UTF8EncodeURI = ""

    For nFor = 1 To Len(strUTF8)

        strWchar = Mid(strUTF8, nFor, 1)

        nAsc = AscW(strWchar)

        If nAsc < 0 Then nAsc = nAsc + 65536

        If (nAsc And &HFF80) = 0 Then

            UTF8EncodeURI = UTF8EncodeURI & strWchar

        ElseIf (nAsc And &HF000) = 0 Then

            strURIchar = "%" & Hex(((nAsc \ 2 ^ 6)) Or &HC0) & Hex(nAsc And &H3F Or &H80)

            UTF8EncodeURI = UTF8EncodeURI & strURIchar

        Else

            strURIchar = "%" & Hex((nAsc \ 2 ^ 12) Or &HE0) & _

                         "%" & Hex((nAsc \ 2 ^ 6) And &H3F Or &H80) & _

                         "%" & Hex(nAsc And &H3F Or &H80)

            UTF8EncodeURI = UTF8EncodeURI & strURIchar

        End If

居然没人来答。。。。

研究了二年半，终于自己搞定了

Function UTF8EncodeURI(strUTF8 As String) As String

    Dim nFor    As Long

    Dim nAsc    As Long

    Dim strWchar    As String

    Dim strURIchar  As String

    

    UTF8EncodeURI = ""

    For nFor = 1 To Len(strUTF8)

        strWchar = Mid(strUTF8, nFor, 1)

        nAsc = AscW(strWchar)

        If nAsc < 0 Then nAsc = nAsc + 65536

        If (nAsc And &HFF80) = 0 Then

            UTF8EncodeURI = UTF8EncodeURI & strWchar

        ElseIf (nAsc And &HF000) = 0 Then

            strURIchar = "%" & Hex(((nAsc \ 2 ^ 6)) Or &HC0) & Hex(nAsc And &H3F Or &H80)

            UTF8EncodeURI = UTF8EncodeURI & strURIchar

        Else

            strURIchar = "%" & Hex((nAsc \ 2 ^ 12) Or &HE0) & _

                         "%" & Hex((nAsc \ 2 ^ 6) And &H3F Or &H80) & _

                         "%" & Hex(nAsc And &H3F Or &H80)

            UTF8EncodeURI = UTF8EncodeURI & strURIchar

        End If

    Next

End Function
