在 Excel VBA 宏中使用 Azure 翻译器

Question

5 年多来，我一直使用此代码在 Excel VBA 宏中将用户输入的英文文本转换为法文或德文。那是在 Microsoft Azure Marketplace 中使用的，因为我的使用量很少，所以它是免费的。

Function MicrosoftTranslate(sText As String, Optional sLanguageFrom As String = "", Optional sLanguageTo As String = "en") As String
Dim sRequest As String, sResponseText As String
   sRequest = "Translate?from=" & sLanguageFrom & "&to=" & sLanguageTo & "&text=" & sText
   sResponseText = MSHttpRequest(sRequest)
   'Debug.Print sResponseText
   MicrosoftTranslate = StringFromXML(sResponseText)
End Function

Function MicrosoftTranslatorDetect(sText As String) As String
 ' returns lowercase two character code eg "fr"
   MicrosoftTranslatorDetect = StringFromXML(MSHttpRequest("Detect?text=" & sText))
End Function

Function MSHttpRequest(sRequest As String) As String
Dim sURL As String, oH As Object, sToken As String
   sURL = "http://api.microsofttranslator.com/V2/Http.svc/" & sRequest
   sToken = GetAccessToken()
   Set oH = CreateObject("MSXML2.XMLHTTP")
   oH.Open "GET", sURL, False
   oH.setRequestHeader "Authorization", "Bearer " & sToken
   oH.send
   MSHttpRequest = oH.responseText
   Set oH = Nothing
End Function

Function GetAccessToken() As String
Static sAccess_Token As String, dtExpiry_Time As Date
Const OAUTH_URI As String = "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13"

'get Your Client ID and client secret from
'https://datamarket.azure.com/developer/applications
Const CLIENT_ID As String = "xxxxxxxxx"
Const CLIENT_SECRET As String = "1234567890abcdefghijklmnopqrstuvwxyz"
Dim sRequest As String, sResponse As String
Dim webRequest As Object

If Now() > dtExpiry_Time Then ' time for a new access token
   Set webRequest = CreateObject("MSXML2.XMLHTTP")

   sRequest = "grant_type=client_credentials" & _
         "&client_id=" & CLIENT_ID & _
         "&client_secret=" & URLEncode(CLIENT_SECRET) & _
         "&scope=http://api.microsofttranslator.com"
   webRequest.Open "POST", OAUTH_URI, False
   webRequest.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
   webRequest.send (sRequest)
   sResponse = webRequest.responseText
   Set webRequest = Nothing

   If InStr(1, sResponse, """error:""", vbTextCompare) > 0 Then
      Err.Raise 9999, "GetAccessToken " & sResponse
   End If

   sAccess_Token = NameValue("access_token", sResponse)
   dtExpiry_Time = Now() + Val(NameValue("expires_in", sResponse)) / 60 / 60 / 24 ' maybe *.95 for safety margin
   'Debug.Print "Token expires at "; Format$(dtExpiry_Time, "hh:mm:ss")
End If
GetAccessToken = sAccess_Token
End Function

现在有了新的 Microsoft Azure，我的搭便车似乎结束了。所以现在我需要转换我的 VBA 代码。我看了看，还没有找到一个很好的参考来帮助转换附加的例程。我在 VBA 方面还不错，但需要帮助来实现这些新功能。

有人可以帮助我或向我指出一些参考资料（对于像我这样的新手），这将使我能够使用新系统。

在我运行某些东西后，我可以决定是否值得为这个小应用程序花钱。

谢谢.....RDK

我在 Access 中使用此代码来翻译单行文本 VBA中的翻译代码

Function TranslatorTextAPI(sText As String)
    'Single step translation code
    'for Key info if authentication is failing goto https://portal.azure.com/ log in and refresh keys and update Key information below
    'if you cannot find keys you can create new azure account goto link below it is a free service for less then 2 million words
    'https://docs.microsoft.com/en-us/azure/cognitive-services/translator/translator-text-how-to-signup
    If Len(sText) > 0 Then 'if blank do nothing return the blank value
        Dim sHost As String
        Dim zTTxt As String
        Dim zKey As String
        Dim startpl, endpl As Integer

        zKey = "subscriptionKey" 'authentication Key from subscription
        sHost = "https://api.cognitive.microsofttranslator.com/translate?api-version=3.0" 'required link for authentication
        sHost = sHost & "&from=fr&to=en" 'determine language from and langauge to
        zTTxt = "[{""text"":" & """" & sText & """}]" 'JSON format spcific requirement [{"text":"value"}] max 5000 characters

        Dim Tlang As Object
        Set Tlang = CreateObject("WinHttp.WinHttpRequest.5.1") 'need to add reference libary "Microsft WinHTTP Service,Version 5.1"
        Tlang.Open "POST", sHost, False 'open connection to "Translator Text API" POST command required
        Tlang.SetRequestHeader "Ocp-Apim-Subscription-Key", zKey 'authentication Required
        Tlang.SetRequestHeader "Content-type", "Application/json" 'Content-type Required
        Tlang.Send zTTxt 'format = [{"text":"Bonjour utilisateur"}]
        Tlang.WaitForResponse 'the response takes 1+ seconds needs wait or delay command or results will fail as response has not returned data yet
        'Debug.Print Tlang.GetAllResponseHeaders

        startpl = 28 'if you use auto languae detect you will need to adjust this number to "69" or greater
        endpl = InStr(startpl, Tlang.ResponseText, """") '[{"translations":[{"text":"Hello user","to":"en"}]}]
        TranslatorTextAPI = Mid(Tlang.ResponseText, startpl, endpl - startpl) 'Parse out translated text
        Tlang.Abort
    Else
        TranslatorTextAPI = sText 'if blank do nothing return the blank value
    End If
End Function

实际上 Azure Coginitve 服务中的 Translator API 从免费层开始。 https://www.microsoft.com/cognitive-services/en-us/pricing

新API的主要区别在于获取token的方式。 http://docs.microsofttranslator.com/oauth-token.html

其他的和我想的一样。你可以在这里找到参考： docs.microsofttranslator.com/text-translate.html
