如何将Excel连接到Microsoft的QnA Maker（VBA）

自由职业者

我会定期收到带有问题的excel文件（我从以前的迭代中得到答案。问题总是相似的），并且我想自动答复。我已经在Microsoft QnAMaker中创建了包含所有问题/答案对的知识库。

如何致电Microsoft的QnAMaker回答来自Excel的问题。我一直在寻找vba示例，但到目前为止我还没有发现任何东西。我相信我需要使用vba从excel发出具有授权的HTTP请求，然后处理响应。有人对我如何提出请求和处理请求有想法吗？

任何帮助表示赞赏。谢谢！

这些是QnAMaker提供的进行呼叫的示例详细信息：

 POST /knowledgebases/d02d1d7e-1bc0-461a-8074-37749cae41b9/generateAnswer
 Host: https://rfp1.azurewebsites.net/qnamaker
 Authorization: EndpointKey cec4b630-9e77-474f-8df4-e6430a5678c8
 Content-Type: application/json
 {"question":"<Your question>"}

我发现了两种方法可以做到这一点。首先是VBA。其次是关于Power Queries。

VBA

可选设置

通过转到文件>选项>自定义功能区>检查开发人员，将开发人员标签添加到功能区
转到“开发人员”标签，然后选择“插入”>“按钮”
将宏命名为“ GetReplies”
点击新建

笔记：

我的QnAKB主要基于此常见问题解答。

VBA设定

在“开发人员”选项卡中，单击“ Visual Basic”按钮（如果未自动打开）
转到工具>参考，然后启用以下库：
按照安装说明导入此JSON库
复制/粘贴：

VBA代码：

Sub GetReplies()

    'User Settings
    Dim questionWorksheetName As String, questionsColumn As String, firstQuestionRow As String, kbHost As String, kbId As String, endpointKey As String

        questionWorksheetName = "Sheet1"
        questionsColumn = "A"
        firstQuestionRow = "2"

        kbHost = "https://**********.azurewebsites.net/qnamaker"
        kbId = "*******-****-****-****-**********"
        endpointKey = "*********-****-****-****-***********"

    'Non-User Settings
    Dim questionWorksheet As Worksheet
        Set questionWorksheet = Sheets(questionWorksheetName)
    Dim startCell As String
        startCell = questionsColumn & firstQuestionRow
    Dim questionsRange As Range
        Set questionsRange = questionWorksheet.Range(startCell, questionWorksheet.Range(startCell).End(xlDown))

    'Loop through all non-blank cells
    Dim answer As String
    For Each cell In questionsRange
        If Not IsEmpty(cell) Then
            answer = GetAnswer(cell.Value, kbHost, kbId, endpointKey)
            'Add answer to cell
            cell.Offset(0, 1).Value = answer
        End If
    Next

End Sub

Function GetAnswer(question, kbHost, kbId, endpointKey) As String
    'HTTP Request Settings
    Dim qnaUrl As String
        qnaUrl = kbHost & "/knowledgebases/" & kbId & "/generateAnswer"
    Dim contentType As String
        contentType = "application/json"
    Dim data As String
        data = "{""question"":""" & question & """}"

    'Send Request
    Dim xmlhttp As New MSXML2.XMLHTTP60

    xmlhttp.Open "POST", qnaUrl, False
        xmlhttp.SetRequestHeader "Content-Type", contentType
        xmlhttp.SetRequestHeader "Authorization", "EndpointKey " & endpointKey
    xmlhttp.Send data

    'Convert response to JSON
    Dim json As Dictionary
    Set json = JsonConverter.ParseJson(xmlhttp.ResponseText)

    Dim answer As Dictionary

    For Each answer In json("answers")
    'Return response
        GetAnswer = answer("answer")
    Next

End Function

适当地编辑顶部的“用户设置”

运行后，我得到：
