使用带有JSON对象的Powershell连接到Google API

Question

我开始通过Powershell连接到Google API。我得到了一个包含以下内容的JSON对象：

{
  "type": "service_account",
  "project_id": "projectidhere",
  "private_key_id": "privatekeyidhere",
  "private_key": "-----BEGIN PRIVATE KEY-----Privatekeyishere---END PRIVATE 
  KEY-----\n",
  "client_email": "emailaccounthere",
  "client_id": "clientidhere",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": 
  "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/termoutest%40test123.iam.gserviceaccount.com" }

该JSON对象是否包含授权给Google API所需的标头信息？

如果是这样，如何将此对象作为标题传递？

谢谢！
