如何使用VBA调用Microsoft Graph API? [英] How to call Microsoft Graph API using VBA?

问题

是否可以使用VBA代码调用Microsoft Graph API?

Is it possible to call Microsoft Graph API using VBA code?

如果是，如何处理O365授权?我已经看到很多话题说要在Microsoft Azure中创建应用程序以获取令牌，但我很惊讶我必须为简单的本地使用而这样做.

If yes, how to handle O365 authorization? I have seen plenty of topics saying to create an application in Microsoft Azure to get a token but I am surprised I must do that for a simple local use.

我尝试过的事情

发现Microsoft Graph之后，我在Graph Explorer中尝试了此API https://graph.microsoft.com/v1.0/planner/tasks

After discovering Microsoft Graph, I tried this API in Graph Explorer https://graph.microsoft.com/v1.0/planner/tasks

我能够在计划程序中创建任务！

I was able to create a task in planner!

因此，在我看来，可以从直接在Outlook中执行的VBA代码中调用此API.

Consequently, in my mind, it was possible to call this API from VBA code executed directly in Outlook.

我在Outlook中创建了此宏:

I created this macro in Outlook:

Sub TaskPlannerCreation()

    Dim PlannerService As New MSXML2.XMLHTTP60
    Dim sData As Variant

    sData = " { ""  ""planId"": ""K9Zv2QHm1U-GSAhd-PTGZfdFeOn"",""bucketId"": ""b6NVNiEIQkGZeBBzn7kWqJvAGvvs"",""title"": ""Outlook task"" } "

    With PlannerService
        .Open "POST", "https://graph.microsoft.com/v1.0/planner/tasks", False
        .setRequestHeader "Content-Type", "application/json"
        .setRequestHeader "Accept", "application/json"
        .setRequestHeader "User-Agent", "xx"
        .Send (sData)

2020年12月3日更新:找到的解决方案在调用Graph Explorer时获得了分析Graph Api令牌的URL(非常适合我):

UPDATE on 12-03-2020 : Solution found to get a Graph Api token analysing URL when calling Graph Explorer (works perfectly for me) :

Function GetToken()

    Dim xml As New MSXML2.XMLHTTP60
    Dim doc As MSHTML.HTMLDocument
    Dim urltoken As String

'copy paste the URL you see when calling Microsoft Graph Explorer and add prompt + domain_hint parameters
    urltoken = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_mode=form_post&nonce=graph_explorer&mkt=fr-FR&client_id={clientid}&response_type=token&scope=openid profile User.ReadWrite User.ReadBasic.All Sites.ReadWrite.All Contacts.ReadWrite People.Read Notes.ReadWrite.All Tasks.ReadWrite Mail.ReadWrite Files.ReadWrite.All Calendars.ReadWrite&prompt=none&domain_hint=organizations"

    xml.Open "GET", urltoken, False

    xml.Send

    If xml.readyState = 4 And xml.Status = 200 Then
        Set doc = New MSHTML.HTMLDocument
        doc.Body.innerHTML = xml.responseText

        GetToken = doc.getElementsByName("access_token")(0).Value

        sSuccess = True
    Else
         MsgBox "Error" & vbNewLine & "Ready state: " & xml.readyState & _
         vbNewLine & "HTTP request status: " & xml.Status
         sSuccess = False
    End If

    Set xml = Nothing

End Function

因此可以使用VBA调用Graph API:)

So using VBA for calling Graph API is possible :)

推荐答案

因此，您显示的代码仅部分正确.这是我发现实际起作用的内容.(这是您提供的，因为我实际上发现一个Json解析器比innerHTML方法更好地处理数据，我还必须使用不同版本的MSXML，因为您引用的那个对我不起作用.)

So the code you show is only partially correct. Here is what I found to actually work. (This is with what you provided as I actually found a Json parser to work with the data better than the innerHTML methods, I also had to use a different version of MSXML since the one you reference wasnt working for me.)

Function GetToken()
    Dim xml As New MSXML2.XMLHTTP60
    Dim doc As MSHTML.HTMLDocument
    Dim urltoken As String

    'copy paste the URL you see when calling Microsoft Graph Explorer and add prompt + domain_hint parameters
    urltoken = "https://login.microsoftonline.com/{tenent id}/oauth2/v2.0/token"

    xml.Open "POST", urltoken, False

    xml.Send("client_id={clientid}&scope=https://graph.microsoft.com/.default&grant_type=client_credentials&client_secret=(cleint secret}")

    If xml.readyState = 4 And xml.Status = 200 Then
        Set doc = New MSHTML.HTMLDocument
        doc.Body.innerHTML = xml.responseText

        GetToken = doc.getElementsByName("access_token")(0).Value

        sSuccess = True
    Else
         MsgBox "Error" & vbNewLine & "Ready state: " & xml.readyState & _
         vbNewLine & "HTTP request status: " & xml.Status
         sSuccess = False
    End If

    Set xml = Nothing
End Function
