【中文标题】如何在 Excel VBA 中对字符串进行 URL 编码?【英文标题】:How can I URL encode a string in Excel VBA? 【发布时间】:2010-09-18 02:32:11 【问题描述】:

是否有内置方法可以在 Excel VBA 中对字符串进行 URL 编码,或者我是否需要手动滚动此功能?

【问题讨论】:

【参考方案1】:

接受的答案的代码在 Access 2013 中因 Unicode 错误而停止,因此我为自己编写了一个具有高可读性的函数,该函数应遵循 RFC 3986 根据Davis Peixoto,并在各种环境中造成最小的麻烦。

注意:必须先替换百分号本身,否则它将对任何先前编码的字符进行双重编码。添加了用 + 替换空格,不是为了符合 RFC 3986,而是为了提供不会因格式化而中断的链接。它是可选的。

Public Function URLEncode(str As Variant) As String
    Dim i As Integer, sChar() As String, sPerc() As String
    sChar = Split("%|!|*|'|(|)|;|:|@|&|=|+|$|,|/|?|#|[|]| ", "|")
    sPerc = Split("%25 %21 %2A %27 %28 %29 %3B %3A %40 %26 %3D %2B %24 %2C %2F %3F %23 %5B %5D +", " ")
    URLEncode = Nz(str)
    For i = 0 To 19
        URLEncode = Replace(URLEncode, sChar(i), sPerc(i))
    Next i
End Function

在根据票数可能会上升或下降的答案中提及“上述”是没有用的。 现在它需要带有PtrSafeLongPtrVBA7 标头。【参考方案3】:

为了更新这一点,从 Excel 2013 开始,现在有一种使用工作表函数 ENCODEURL 对 URL 进行编码的内置方法。

要在您的 VBA 代码中使用它,您只需调用

EncodedUrl = WorksheetFunction.EncodeUrl(InputString)

Documentation

【讨论】:

当我不得不在字段中使用连续逗号对 csv 数据进行编码时,它失败了。必须在答案中使用上述 utf8 版本 @SalmanSiddique 很高兴知道这些限制。可能值得一提的是您使用的哪个 utf8 版本不止一个 Application.WorksheetFunction.EncodeUrl(myString) 完美地满足了我的需求 - 希望这个答案将得到足够的支持以取代以前的超级旧版本 @jamheadart 公平地说,这个答案链接到已接受答案的第一行 这很公平。我没注意到。我看到了大量的代码和日期,并认为下面会有更好的答案!【参考方案4】:

VBA-tools 库有一个功能:

http://vba-tools.github.io/VBA-Web/docs/#/WebHelpers/UrlEncode

它的工作方式似乎类似于 javascript 中的encodeURIComponent()

【讨论】:

【参考方案5】:

不,没有任何内置功能(直到 Excel 2013 - see this answer)。

此答案中有URLEncode() 的三个版本。

支持 UTF-8 的函数。 您可能应该使用这个(或 Tom 的 the alternative implementation)以符合现代要求。 出于参考和教育目的,不支持 UTF-8 的两个函数: 在第三方网站上找到的,按原样包含在内。 (这是答案的第一个版本) 一个优化版本,由我编写

支持 UTF-8 编码并基于 ADODB.Stream 的变体(在您的项目中包含对“Microsoft ActiveX 数据对象”库的最新版本的引用):

Public Function URLEncode( _
   ByVal StringVal As String, _
   Optional SpaceAsPlus As Boolean = False _
) As String
  Dim bytes() As Byte, b As Byte, i As Integer, space As String

  If SpaceAsPlus Then space = "+" Else space = "%20"

  If Len(StringVal) > 0 Then
    With New ADODB.Stream
      .Mode = adModeReadWrite
      .Type = adTypeText
      .Charset = "UTF-8"
      .Open
      .WriteText StringVal
      .Position = 0
      .Type = adTypeBinary
      .Position = 3 ' skip BOM
      bytes = .Read
    End With

    ReDim result(UBound(bytes)) As String

    For i = UBound(bytes) To 0 Step -1
      b = bytes(i)
      Select Case b
        Case 97 To 122, 65 To 90, 48 To 57, 45, 46, 95, 126
          result(i) = Chr(b)
        Case 32
          result(i) = space
        Case 0 To 15
          result(i) = "%0" & Hex(b)
        Case Else
          result(i) = "%" & Hex(b)
      End Select
    Next i

    URLEncode = Join(result, "")
  End If
End Function

这个函数是found on freevbcode.com:

Public Function URLEncode( _
   StringToEncode As String, _
   Optional UsePlusRatherThanHexForSpace As Boolean = False _
) As String

  Dim TempAns As String
  Dim CurChr As Integer
  CurChr = 1

  Do Until CurChr - 1 = Len(StringToEncode)
    Select Case Asc(Mid(StringToEncode, CurChr, 1))
      Case 48 To 57, 65 To 90, 97 To 122
        TempAns = TempAns & Mid(StringToEncode, CurChr, 1)
      Case 32
        If UsePlusRatherThanHexForSpace = True Then
          TempAns = TempAns & "+"
        Else
          TempAns = TempAns & "%" & Hex(32)
        End If
      Case Else
        TempAns = TempAns & "%" & _
          Right("0" & Hex(Asc(Mid(StringToEncode, _
          CurChr, 1))), 2)
    End Select

    CurChr = CurChr + 1
  Loop

  URLEncode = TempAns
End Function

我已经纠正了其中的一个小错误。


我会使用上述更高效(约 2 倍)的版本:

Public Function URLEncode( _
   StringVal As String, _
   Optional SpaceAsPlus As Boolean = False _
) As String

  Dim StringLen As Long: StringLen = Len(StringVal)

  If StringLen > 0 Then
    ReDim result(StringLen) As String
    Dim i As Long, CharCode As Integer
    Dim Char As String, Space As String

    If SpaceAsPlus Then Space = "+" Else Space = "%20"

    For i = 1 To StringLen
      Char = Mid$(StringVal, i, 1)
      CharCode = Asc(Char)
      Select Case CharCode
        Case 97 To 122, 65 To 90, 48 To 57, 45, 46, 95, 126
          result(i) = Char
        Case 32
          result(i) = Space
        Case 0 To 15
          result(i) = "%0" & Hex(CharCode)
        Case Else
          result(i) = "%" & Hex(CharCode)
      End Select
    Next i
    URLEncode = Join(result, "")
  End If
End Function

请注意,这两个函数都不支持 UTF-8 编码。

【讨论】:

我使用了您的“更高效(约 2 倍)的版本”,效果很好!谢谢。 @Chris 谢谢。 :) 请注意,如果您使用 ADODB.Stream 对象,您可能可以制作一个兼容 UTF-8 的版本,它可以进行必要的字符串转换。如何使用 VBA 或 VBScript 生成 UTF-8 的示例遍布 Internet。 如果性能是一个问题 - 考虑重构以使用“替换”通过循环整数 0 到 255 并执行以下操作:案例 0 到 36、38 到 47、58 到 64、91 到 96, 123 到 255 str_Input = Replace(str_Input, Chr(int_char_num), "%" & Right("0" & Hex(255), 2)) 这实际上会适得其反。 VB 字符串是不可变的,对一个字符串执行 255 次替换会为迭代的每一步分配一个新的完整字符串。就空间和内存而言,这肯定比将字母分配给预先分配的数组更浪费。 此代码将在 Access 2013 中出现 Unicode 错误时停止,因为它同时处理太多和太少的字符。【参考方案6】:

从 Office 2013 开始使用这个内置函数here。

如果在办公室 2013 之前

Function encodeURL(str As String)
Dim ScriptEngine As ScriptControl
Set ScriptEngine = New ScriptControl
ScriptEngine.Language = "JScript"

ScriptEngine.AddCode "function encode(str) return encodeURIComponent(str);"
Dim encoded As String


encoded = ScriptEngine.Run("encode", str)
encodeURL = encoded
End Function

添加 Microsoft Script Control 作为参考,您就完成了。

与上一篇相同,只是完成了功能..works!

完成。好的,我不知道我可以编辑,不幸的是,你没有获得编辑积分! 仅供参考,我尝试更新其他帖子,但我的编辑得到了审核!例如。 Micha 在 18 小时前对此进行了评论:拒绝此编辑不正确或试图回复或评论现有帖子。 alex2410 在 18 小时前对此进行了评论:拒绝此编辑不正确或试图回复或评论现有帖子。 bansi 在 18 小时前对此进行了评论:拒绝此编辑不正确或试图回复或评论现有帖子。 - ScriptControl 不适用于 64 位 Office 版本,请检查 solution via htmlfile ActiveX 和 workaround getting ScriptControl to work with Excel x64。【参考方案7】:

WorksheetFunction.EncodeUrl 相同,支持 UTF-8:

  buffer = String$(Len(url) * 12, "%")

  For i = 1 To Len(url)
    c = AscW(Mid$(url, i, 1)) And 65535

    Select Case c
      Case 48 To 57, 65 To 90, 97 To 122, 45, 46, 95  ' Unescaped 0-9A-Za-z-._ '
        n = n + 1
        Mid$(buffer, n) = ChrW(c)
      Case Is <= 127            ' Escaped UTF-8 1 bytes U+0000 to U+007F '
        n = n + 3
        Mid$(buffer, n - 1) = Right$(Hex$(256 + c), 2)
      Case Is <= 2047           ' Escaped UTF-8 2 bytes U+0080 to U+07FF '
        n = n + 6
        Mid$(buffer, n - 4) = Hex$(192 + (c \ 64))

        n = n + 12
        Mid$(buffer, n - 10) = Hex$(240 + (c \ 262144))
        Mid$(buffer, n - 7) = Hex$(128 + ((c \ 4096) Mod 64))
        Mid$(buffer, n - 4) = Hex$(128 + ((c \ 64) Mod 64))
        Mid$(buffer, n - 1) = Hex$(128 + (c Mod 64))

    End Select
  Next

  EncodeURL = Left$(buffer, n)

这里的解决方案都不适用于我,但这很可能是由于我缺乏 VBA 经验。也可能是因为我只是复制并粘贴了上面的一些函数,不知道使它们在 VBA for applications 环境中工作可能需要的细节。

我的需要只是使用包含一些挪威语言特殊字符的 url 发送 xmlhttp 请求。上面的一些解决方案甚至对冒号进行了编码,这使得网址不适合我的需要。

然后我决定编写自己的 URLEncode 函数。它不使用更聪明的编程,例如来自@ndd 和@Tom 的编程。我不是一个很有经验的程序员,但我必须尽快完成这项工作。

我意识到问题在于我的服务器不接受 UTF-16 编码,因此我必须编写一个将 UTF-16 转换为 UTF-8 的函数。 here 和 here 找到了一个很好的信息来源。

我没有对它进行广泛的测试,以检查它是否适用于具有更高 unicode 值并且会产生超过 2 个字节的 utf-8 字符的字符的 url。我并不是说它会解码所有需要解码的东西(但很容易修改以在select case 语句中包含/排除字符),也不是说它可以处理更高的字符,因为我还没有完全测试过。但我分享代码是因为它可能对试图理解问题的人有所帮助。

类似于 Michael-O 的代码,只是不需要引用(后期绑定),并且少了一行。 * 我读到,在 excel 2013 中它可以更容易地完成,如下所示: WorksheetFunction.EncodeUrl(InputString)

Public Function encodeURL(str As String)
    Dim ScriptEngine As Object
    Dim encoded As String

    Set ScriptEngine = CreateObject("scriptcontrol")
    ScriptEngine.Language = "JScript"

    encoded = ScriptEngine.Run("encodeURIComponent", str)

    encodeURL = encoded
End Function

【讨论】:

ScriptControl 不适用于 64 位 Office 版本,请检查 solution via htmlfile ActiveX 和 workaround getting ScriptControl to work with Excel x64。【参考方案13】:

如果您还希望它在 MacOs 上工作,请创建一个单独的函数

Function macUriEncode(value As String) As String

    Dim script As String
    script = "do shell script " & """/usr/bin/python -c 'import sys, urllib; print urllib.quote(sys.argv[1])' """ & Chr(38) & " quoted form of """ & value & """"

    macUriEncode = MacScript(script)

End Function

虽然,这个已经很老了。我提出了一个基于this 的解决方案答案:

Dim ScriptEngine As ScriptControl
Set ScriptEngine = New ScriptControl
ScriptEngine.Language = "JScript"

ScriptEngine.AddCode "function encode(str) return encodeURIComponent(str);"
Dim encoded As String
encoded = ScriptEngine.Run("encode", "€ömE.sdfds")

添加 Microsoft Script Control 作为参考,您就完成了。

顺便说一句,由于 JS 部分,这是完全兼容 UTF-8 的。 VB 将正确地从 UTF-16 转换为 UTF-8。

【讨论】:

太棒了,我不知道你可以在 VBA 中使用 JS 代码。我的整个世界现在都打开了。 太棒了。这正是我所需要的。备注:如果不想添加引用,可以: A) Dim ScriptEngine As Object B) 设置 ScriptEngine = CreateObject("scriptcontrol")。顺便说一句,您似乎可以像这样直接调用 encodeURIComponent,而不是在 JS 中创建函数:coded = ScriptEngine.Run("encodeURIComponent", str) @ElScripto,继续发布一个改进的答案,它指的是我的。 ScriptControl 不适用于 64 位 Office 版本,请检查 solution via htmlfile ActiveX 和 workaround getting ScriptControl to work with Excel x64。
