google-api-ruby-client当前用户没有足够的权限来执行请求的操作

我使用google-api-ruby-client google-api-ruby-client为我的后端服务器validationandroid inapppurchase代码（见下文）：

require 'google/api_client' require 'google/api_client/client_secrets' require 'google/api_client/auth/installed_app' API_VERSION = 'v1.1' service_account_email = '[e-mail]' # Email of service account key_file = 'xxx.p12' # File containing your private key key_secret = 'notasecret' # Password to unlock private key scope_url = 'https://www.googleapis.com/auth/androidpublisher' client = Google::APIClient.new( :application_name => 'Ruby Inapppurchases validate', :application_version => '1.0.0') key = Google::APIClient::KeyUtils.load_from_pkcs12(key_file, key_secret) 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 => scope_url, :issuer => service_account_email, :signing_key => key) client.authorization.fetch_access_token! publisher = client.discovered_api('androidpublisher', 'v1.1') p client.execute( api_method: publisher.inapppurchases.get, parameters: { packageName: 'com.examble', productId: 'android.test.purchased', token: "inapp:com.examble:android.test.purchased" }).data 

我按照api的说明，但我的错误如下：

  #{"errors"=>[{"domain"=>"androidpublisher", "reason"=>"permissionDenied", "message"=>"The current user has insufficient permissions to perform the requested operation."}], "code"=>401, "message"=>"The current user has insufficient permissions to perform the requested operation."}}> 

这让我很烦恼。 谁能帮我？
