Question

似乎无法让 GraphAPI 从 PowerShell 中查询 Bitlocker 恢复密钥。使用 Azure AD 应用程序注册

Grant_Type    = "client_credentials"
Scope         = "https://graph.microsoft.com/.default"
client_Id     = $ApplicationID
Client_Secret = $AccessSecret
} 

$headr = @{
Authorization = "Bearer $($token)"
'ocp-client-name' = ""
'ocp-client-version' = "1.2"
}

$ConnectGraph = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$TenatDomainName/oauth2/v2.0/token" `
-Method POST -Body $Body

$token = $ConnectGraph.access_token

$GrapGroupUrl = 'https://graph.microsoft.com/beta/bitlocker/recoveryKeys'
(Invoke-RestMethod -Headers $headr -Uri $GrapGroupUrl -Method Get)

错误：

  "error": {
    "code": "UnknownError",
    "message": "{\"odata.error\":{\"Code\":\"authorization_error\",\"Message\":{\"Lang\":\"en\",\"Value\":\"Failed to authorize caller, the caller wasn't owner of the device 
or one of the admin roles.\"},\"Values\":[{\"Item\":\"subCode\",\"Value\":\"error_authorization_request_denied\"},{\"Item\":\"requestId\",\"Value\":\"xxxxxxxxxx\"},{\"Item\":\"time\",\"Value\":\"2020-11-19T04:43:13.6957327Z\"}]}}",
    "innerError": {
      "date": "2020-11-19T04:43:13",
      "request-id": "xxxxxxxxx",
      "client-request-id": "xxxxxx"
    }
  }
}```

对于这个问题，错误是由不正确的授权类型（授权流程）引起的。正如我们所见，document 向我们展示了这张图 api 需要 Delegated 权限 BitLocker.ReadBasic.All, BitLocker.Read.All，它不支持“申请”权限。

所以我们不能使用客户端凭证流来获取访问令牌，我们需要使用username/password流来获取。请在下面的屏幕截图中参考我的测试。

执行运行命令后，我们可以看到结果没有显示错误信息。
