Question

所以我使用破折号（基于sinatra的框架）创建仪表板，我需要从Analytics API获取数据，并将其显示在仪表板中。所以我有以下ruby代码，oauth返回此错误：

{
  "error" : "invalid_request",
  "error_description" : "Required parameter is missing: grant_type"
}

这是代码：

require 'openssl'
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
require 'google/api_client'
require 'date'

# Update these to match your own apps credentials
service_account_email = ENV['chrezworld@dashing-project-1297.iam.gserviceaccount.com'] # Email of service account
key_file = 'key.p12' # File containing your private key
key_secret = 'notasecret' # Password to unlock private key
profileID = ENV['77142386'] # Analytics profile ID.

# Get the Google API client
client = Google::APIClient.new(
  :application_name => ENV['dashing project'], 
  :application_version => '0.01'
)

visitors = []

# Load your credentials for the service account
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 => 'https://www.googleapis.com/auth/analytics.readonly',
  :issuer => service_account_email,
  :signing_key => key)

# Start the scheduler
SCHEDULER.every '5s', :first_in => 0 do

  # Request a token for our service account
  client.authorization.fetch_access_token!

  # Get the analytics API
  analytics = client.discovered_api('analytics','v3')

  # Execute the query
  visitCount = client.execute(:api_method => analytics.data.realtime.get, :parameters => { 
    'ids' => "ga:" + profile_id,
    'metrics' => "ga:activeVisitors",
  })

  visitors << { x: Time.now.to_i, y: visits.to_i }

  # Update the dashboard
  send_event('visitor_count_real_time', points: visitors)

end

我不确定那个例子多大了。 Ruby API似乎记录得非常糟糕，因为它仍处于alpha阶段，所以它可能会有所改变。我最近做了一个快速的ruby示例，它适用于最新版本的API 0.9.6

首先，您要进入Google云端控制台，并为您的服务帐户导出JSON密钥文件。然后把它放在某处，红宝石可以读取它。你需要将它的路径传递给ENV。

require 'google/apis/analytics_v3'
require 'googleauth'

ENV['GOOGLE_APPLICATION_CREDENTIALS'] = "service_account_credentials.json"

Analytics = Google::Apis::AnalyticsV3
analytics = Analytics::AnalyticsService.new
scopes = [Analytics::AUTH_ANALYTICS_READONLY]
analytics.authorization = Google::Auth.get_application_default(scopes)
accounts = analytics.list_accounts
accounts.items.each do |a| puts a.name end

我发现这是使用服务帐户查询Ruby API的最简单方法。

另外，请确保将Google Analytics帐户的访问权限授予您的服务帐户。

从那里您可以查询记录的其他方法here。

具体来说，你可以做到：

puts analytics.get_realtime_data("ga:XXXXX", "ga:activeVisitors").totals_for_all_results

Google AnalyticsAPI：缺少必需参数：grant_type
