Azure HTTP POST 请求来自 Power BI 的访问令牌

Question

是否可以使用 HTTP POST 请求从 Power BI 电源查询获取 azure AD 应用程序访问令牌？

HTTP POST 请求：

//request url
https://login.microsoftonline.com/<tenant id>/oauth2/token

//header
Content-Type: application/x-www-form-urlencoded

//request body
grant_type=client_credentials
client_id=625bc9f6xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
client_secret=bCBxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
resource=api://xxxxxxxxxxxxxxxxxxxxxxxxxxx

参考：https://docs.microsoft.com/en-us/azure/active-directory/azuread-dev/v1-oauth2-client-creds-grant-flow#example

好的，它看起来很简单，并且可以很好地处理 Postman 或 python 请求，并显示带有 json 数据的成功响应。现在我的问题是我想用 Power BI power query 通过这个请求这是我的 power query

let
  apiUrl = "https://login.microsoftonline.com/<tenant id>/oauth2/token",
    body = "{
    ""grant_type"": ""client_credentials"",
    ""client_id"": ""625bc9f6xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"",
    ""client_secret"": ""bCBxxxxxxxxxxxxxxxxxxxxxxxxxxx"",
    ""resource"": ""api://xxxxxxxxxxxxxxxxxxxxxxxxxxx""
    }",

  Source = Web.Contents(apiUrl, [Headers=[#"Content-Type"="application/x-www-form-urlencoded"],
           Content=Text.ToBinary(body)]),
  FormatAsJson = Json.Document(Source)
in
    FormatAsJson

但是它说请求错误

DataSource.Error: Web.Contents failed to get contents from 
'https://login.microsoftonline.com/61ed5503-xxxxxxxxxxxxxxxxx/oauth2/token' (400): Bad Request

我错过了什么或者为什么它说请求错误？是不是REST API的原因吗？还是有其他方法可以实现？

我解决了，实际上我不得不添加一些额外的条款，也是我自己犯的一个愚蠢的错误，正确的查询

let
  apiUrl = "https://login.windows.net/61xxxxxxxxxxxx/oauth2/token",
    body = [
          client_id="3728xxxxxxxxxxxxxx5",
          grant_type="client_credentials",
          client_secret="bxxxxxxxxxxxxh",
          resource="api://xxxxxxxxxxxxxxxx5"
],

  Source = Json.Document(Web.Contents(apiUrl, [Headers = [Accept = "application/json"],
 Content = Text.ToBinary(Uri.BuildQueryString(body))]))
in
Source
