正在使用 Garb 获取 Google 个分析配置文件

Question

我使用 Garb(0.9.8) to fetch data from Google Analytics from our server directly using OAuth1. As Google only supports OAuth2 now so I switched to Signet gem 并使用服务帐户直接从服务器获取 access_token，因为我们只需要服务器到服务器的交互。

key = Google::APIClient::KeyUtils.load_from_pkcs12(p12_key_path, 'notasecret')
client = Google::APIClient.new(application_name: 'Service account demo', application_version: '0.0.1')
client.authorization = Signet::OAuth2::Client.new(
  :token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
  :audience => 'https://accounts.google.com/o/oauth2/token',
  :scope => ['https://www.googleapis.com/auth/analytics', 'https://www.googleapis.com/auth/analytics.readonly'],
  :issuer => <service account email>,
  :signing_key => key
)

access_token = client.authorization.fetch_access_token!["access_token"]

令牌有效，我在 Google API 游乐场仔细检查了它。服务帐户已添加为对我的 Google Analytics 帐户具有所有权限的用户。如果可行，我想使用 Garb 而不是完全切换到 google-api-client gem 以避免重写大量现有代码。然后让 Garb 使用获得的 access_token 并获取所有配置文件，我做了以下

garbsession = Garb::Session.new
garbsession.access_token = access_token
Garb::Management::Profile.all(garbsession)

但我收到一个错误：

NoMethodError: undefined method `get' for #<String:0xd877aa0>

我是不是做错了什么？我可以在 Garb 中使用通过其他方法获得的访问令牌，然后访问 Google Analytics API 吗？

Answer 1

我犯的错误是 Garb::Session.access_token 应该是 OAuth2 客户端的一个实例，而不是访问令牌本身。我在我的答案中发布了工作代码，以便以后可以帮助其他人！在浏览 Legato gem 寻找问题解决方案时遇到代码。 Github 从我找到解决方案的地方发出 link - https://github.com/tpitale/legato/issues/90

p12_key_path = File.join(Rails.root, "config", <p12_key_path>)
key = Google::APIClient::KeyUtils.load_from_pkcs12(p12_key_path, 'notasecret')
auth_client = Signet::OAuth2::Client.new(
  token_credential_uri: 'https://accounts.google.com/o/oauth2/token',
  audience: 'https://accounts.google.com/o/oauth2/token',
  scope: 'https://www.googleapis.com/auth/analytics.readonly',
  issuer: <ga_service_account email>,
  signing_key: key
)
access_token = auth_client.fetch_access_token!
raise "Google OAuth Access Token is blank" if access_token["access_token"].blank?
oauth_client = OAuth2::Client.new("", "", {
    authorize_url: 'https://accounts.google.com/o/oauth2/auth',
    token_url: 'https://accounts.google.com/o/oauth2/token'
  })
token = OAuth2::AccessToken.new(oauth_client, access_token["access_token"], expires_in: 1.hour)
Garb::Session.access_token = token

profile = Garb::Management::Profile.all
