问你能不能通过web请求，在不使用client_id的情况下，通过用户名和密码获取Azure的访问令牌？

EN

$postParams = @{
  grant_type = 'password'
  client_id  = $ClientId
  username   = $Username
  password   = $Password
  scope      = 'https://graph.microsoft.com/.default'
}

Write-Host "Getting access token for app"
  
Invoke-RestMethod `
  -Uri https://login.microsoftonline.com/$TenantId/oauth2/v2.0/token `
  -Method POST `
  -ContentType application/x-www-form-urlencoded `
  -Body $postParams
