Azure 获取指标“身份验证失败”问题

我正在创建一个 PowerShell 脚本来从 Azure 获取指标。我有一个应用程序注册，具有 Insights-UserMetric.Read.All（应用程序类型）的 API 权限。此外，在订阅级别还为此应用程序分配了监控读者角色。运行脚本时，我收到错误：

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

我尝试将角色提升为贡献者，只是为了检查我是否没有足够的权限，但即使拥有贡献者角色，我仍然收到同样的错误

脚本如下：

$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

感谢任何形式的指导

问题已解决。Token 部分已修复：

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