Google应用组设置API :：500后端错误

Question

每当我尝试从我们的Google Apps实例访问组时，我都会得到以下响应：

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "backendError",
    "message": "Backend Error"
   }
  ],
  "code": 500,
  "message": "Backend Error"
 }
}

我使用的代码如下：

begin
  require 'google/api_client'
rescue LoadError
  puts "You need the google-api-ruby-client gem..."
  puts "$ gem install google-api-client"
  exit 1
end

client = Google::APIClient.new(application_name: "Group Modifier")

## Use key to authenticate and generate token
key = Google::APIClient::PKCS12.load_key("#{File.dirname(__FILE__)}/mykey.p12", 'notasecret')
service_account = Google::APIClient::JWTAsserter.new(
  'mydeveloperid@developer.gserviceaccount.com',
  'https://www.googleapis.com/auth/apps.groups.settings',
  key)

client.authorization = service_account.authorize

groupssettings = client.discovered_api('groupssettings', 'v1')

result = client.execute(
    :api_method => groupssettings.groups.get,
    :parameters => { 'groupUniqueId' => 'mygroup@mydomain.com', 'alt' => 'json' }
)

puts result.body

我已经在Google Apps管理控制台和https://cloud.google.com/console中的"Manage API client access“中添加了正确的权限。

我甚至注意到当我使用"https://developers.google.com/admin-sdk/groups-settings/v1/reference/groups/get#try-it“时，它不会返回任何东西。

请帮帮我

我最终通过使用git repo主页上的一些示例代码解决了我的问题。这是我想出来的：

begin
  require 'google/api_client'
rescue LoadError
  puts "You need the google-api-ruby-client gem..."
  puts "$ gem install google-api-client"
  exit 1
end

client = Google::APIClient.new

key = Google::APIClient::KeyUtils.load_from_pkcs12("#{File.dirname(__FILE__)}/mykey.p12", 'notasecret')
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/apps.groups.settings',
  :issuer => 'mydeveloperid@developer.gserviceaccount.com',
  :person => 'myemail@mydomain.com',
  :signing_key => key)
client.authorization.fetch_access_token!

groupssettings = client.discovered_api('groupssettings', 'v1')

result = client.execute(
    :api_method => groupssettings.groups.get,
    :parameters => { :groupUniqueId => 'mygroup@mydomain.com', :alt => 'json' }
)

puts result.body
