Azure取得指標「身份驗證失敗」問題

Azure取得指標「身份驗證失敗」問題

我正在建立一個 PowerShell 腳本來從 Azure 取得指標。我有一個應用程式註冊,具有 Insights-UserMetric.Read.All(應用程式類型)的 API 權限。也監視在訂閱層級分配給此應用程式的讀者角色。運行腳本時出現錯誤:

{   "error": {     "code": "AuthenticationFailed",     "message": "Authentication failed."   } }

我嘗試將角色提升為貢獻者只是為了檢查我是否沒有足夠的權限,但即使使用貢獻者角色我也會遇到相同的錯誤

這是腳本:

$ClientId = 'someClientId'
$ClientSecret = 'someClientSecret'
$Tenantid = 'someTenantId'

$TokenBody = @{
    Grant_Type = "client_credentials"
    Scope = "https://graph.microsoft.com/.default"
    Client_Id = $ClientId
    Client_Secret = $ClientSecret
}
$TokenResponse = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$Tenantid/oauth2/v2.0/token" -Method POST -Body $TokenBody

$Headers = @{
    "Authorization" = "Bearer $($tokenResponse.access_token)"
    "Content-type" = "application/json"
}

$Uri = 'https://management.azure.com/subscriptions/$subscriptionId/resourceGroups/$resourceGroup/providers/Microsoft.EventHub/namespaces/$eventHub/providers/Microsoft.Insights/metrics?api-version=2018-01-01'

Invoke-RestMethod -Headers $Headers -Uri $Uri -Method GET

感謝任何形式的指導

問題解決了。令牌部分已修復:

$TokenBody = @{
    Grant_Type = "client_credentials"
    Scope = "https://management.azure.com/.default"
    Client_Id = $ClientId
    Client_Secret = $ClientSecret
    Tenant_Id = $TenantId
}
