Google通过VBA进行接受翻译的翻译

Question

[我正在尝试通过VBA使用谷歌翻译API（到目前为止，在python中有效），我发现python请求和VBA之间的唯一区别在于标头“ accept-encoding”，即python使用“应用程序/ gzip”并可以工作，但是即使我通过代码更改了VBA，它也会自动更改为“ gzip，放气”。这是代码：

Function Test_GoogleTranslate()
    Dim strTranslate As String
    Dim objRequest As Object
    Dim strUrl As String
    Dim blnAsync As Boolean
    Dim strResponse As String
    Dim strWeather As String
    Dim payload As String
    Set objRequest = CreateObject("MSXML2.XMLHTTP")
    payload = "target=es&q=something&source=en"
    strTranslate = "https://google-translate1.p.rapidapi.com/language/translate/v2"
    strTranslate = strTranslate & "?" & payload  
    With objRequest
    .Open "POST", strTranslate, True
    .setRequestHeader "host", "google-translate1.p.rapidapi.com"
    .setRequestHeader "x-forwarded-port", "443"
    .setRequestHeader "x-forwarded-proto", "https"
    .setRequestHeader "connection", "keep-alive"


    .setRequestHeader "content-type", "application/x-www-form-urlencoded"
    .setRequestHeader "accept-encoding", "application/gzip"
    .setRequestHeader "x-rapidapi-host", "google-translate1.p.rapidapi.com"
    .setRequestHeader "x-rapidapi-key", "856e8ba78dmsh443766612c5a923p14f661jsn72323e803261"
    .Send
        While objRequest.readyState <> 4
            DoEvents
        Wend
        strResponse = .ResponseText
    End With
    MsgBox (strResponse)
End Function

当我在python中将accept-encoding更改为“ gzip，deflate”时，它崩溃了，所以我认为这可能是问题所在。非常感谢您的帮助

我使用Google Translate and Excel VBA对象在MSXML2.ServerXMLHTTP上取得了一些成功。我注意到您正在使用MSXML2.XMLHTTP。该解决方案似乎只设置了User-Agent请求标头即可，因此我没有深入研究accept-encoding等。

MSXML2.ServerXMLHTTP和MSXML2.XMLHTTP之间的差异在此question中已涉及，可能对您有用。

使用MSXML2.ServerXMLHTTP的工作代码：

Option Explicit

Sub Test()

    Debug.Print Translate("Hello", "en", "fr", True) ' french
    Debug.Print Translate("Hello", "en", "de", True) ' german
    Debug.Print Translate("Hello", "en", "pt", True) ' portuguese
    Debug.Print Translate("Hello", "en", "ru", False) ' russian - use romanised alphabet
    Debug.Print Translate("Hello", "en", "ru", True) ' russian - use cyrillic
    ' ThisWorkbook.Sheets(1).Range("A1").Value = Translate("Hello", "en", "ru", True)
    Debug.Print Translate("Hello", "en", "zh-CN", False) ' chinese simplified - use romanised alphabet
    Debug.Print Translate("Hello", "en", "zh-CN", True) ' chinese simplified - use chinese script
    ' ThisWorkbook.Sheets(1).Range("B1").Value = Translate("Hello", "en", "zh-CN", True)

End Sub

Public Function Translate(strInput As String, strFromLanguageCode As String, strToLanguageCode As String, blnTargetAlphabet As Boolean) As String

    Dim strURL As String
    Dim objHTTP As Object
    Dim objHTML As Object
    Dim objDivs As Object, objDiv
    Dim strTranslatedT0 As String
    Dim strTranslatedO1 As String

    ' send query to web page
    strURL = "https://translate.google.com/m?hl=" & strFromLanguageCode & _
        "&sl=" & strFromLanguageCode & _
        "&tl=" & strToLanguageCode & _
        "&ie=UTF-8&prev=_m&q=" & strInput

    Set objHTTP = CreateObject("MSXML2.ServerXMLHTTP")
    objHTTP.Open "GET", strURL, False
    objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
    objHTTP.send ""

    ' create a html document
    Set objHTML = CreateObject("htmlfile")
    With objHTML
        .Open
        .Write objHTTP.responseText
        .Close
    End With

    ' o1 has Anglicised translation, t0 as tranlsation in target language
    Set objDivs = objHTML.getElementsByTagName("div")
    For Each objDiv In objDivs
        If objDiv.className = "o1" Then
            strTranslatedO1 = objDiv.innerText
        End If
        If objDiv.className = "t0" Then
            strTranslatedT0 = objDiv.innerText
        End If
    Next objDiv

    ' choose which to return
    If blnTargetAlphabet Then
        Translate = strTranslatedT0
    Else
        Translate = strTranslatedO1
    End If

CleanUp:
    Set objHTML = Nothing
    Set objHTTP = Nothing

End Function

结果：

Bonjour

VBA立即窗口不打印西里尔字母或中文字符，但是您可以通过输出到单元格来看到此功能的工作：
