我试图通过Oauth2访问Google Drive API，但遇到了一个错误，在搜索时没有产生任何结果。

这是我的代码

require "oauth2"
require "google/apis/gmail_v1"
require "google/apis/drive_v3"
require "googleauth"

token = { 
    access_token: ...,
    refresh_token: ...,
}

def get_gmail_service(token)
  service = Google::Apis::GmailV1::GmailService.new
  service.authorization = oauth_authorization(token,
    [ Google::Apis::GmailV1::AUTH_GMAIL_READONLY, Google::Apis::GmailV1::AUTH_GMAIL_LABELS]
  )
  service.request_options.retries = 3
  service
end

def get_drive_service(token)
  service = Google::Apis::DriveV3::DriveService.new
  service.authorization = oauth_authorization(token,
    [ Google::Apis::DriveV3::AUTH_DRIVE ]
  )
  service.request_options.retries = 3
  service
end

def oauth_authorization token, scope
  Signet::OAuth2::Client.new({
    authorization_uri: "https://accounts.google.com/o/oauth2/auth",
    token_credential_uri: "https://accounts.google.com/o/oauth2/token",
    client_id: ENV["G_CLIENT_ID"],
    client_secret: ENV["G_CLIENT_SECRET"],
    access_token: token["access_token"],
    refresh_token: token["refresh_token"],
    scope: scope
  })
end

get_gmail_service(token).create_user_label('me', 'test') #=> WORKS
get_drive_service(token).list_files #=> ERROR

这是我得到的错误

Google::Apis::AuthorizationError:Unauthorized
{
  "error": {
    "code": 401,
    "message": "The caller does not have permission",
    "errors": [
      {
        "message": "Active session is invalid. Error code: 4",
        "domain": "global",
        "reason": "authError",
        "location": "Authorization",
        "locationType": "header"
      }
    ],
    "status": "PERMISSION_DENIED"
  }
}

从所有搜索来看，令牌似乎已经过期，但我认为令牌没有过期，因为它们同时在Gmail API上工作。
”我试过什么？**
1.我启用了驱动器API。
1.确保同意屏幕的OAuth2范围为'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/gmail.modify https://www.googleapis.com/auth/gmail.labels https://www.googleapis.com/auth/drive',
1.已尝试使用DriveV2而不是V3客户端
1.搜索类似错误的时间。几乎没有关于"Active session is invalid. Error code: 4"的结果
