我已经从

http://code.google.com/p/google-api-ruby-client/source/browse/service_account/analytics.rb?repo=samples

但是，我一直在努力让它发挥作用，但无论我多么努力，它都会继续付出！这是我不断收到的错误

C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/signet-0.4.5/lib/signet/oauth_2/client.rb:875:in `fetch_access_token': Authorization failed.  Server message: (Signet::Authorization
Error)
{
  "error" : "invalid_grant"
}
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/signet-0.4.5/lib/signet/oauth_2/client.rb:888:in `fetch_access_token!'

我该如何解决这个问题？

这是我的完整代码

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

# Update these to match your own apps credentials
service_account_email = 'xxxxxx' # Email of service account
key_file = 'privatekey.p12' # File containing your private key
key_secret = 'notasecret' # Password to unlock private key
profileID = 'xxxxx' # Analytics profile ID.


client = Google::APIClient.new()

# Load our 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)

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

analytics = client.discovered_api('analytics','v3')

startDate = DateTime.now.prev_month.strftime("%Y-%m-%d")
endDate = DateTime.now.strftime("%Y-%m-%d")

visitCount = client.execute(:api_method => analytics.data.ga.get, :parameters => { 
  'ids' => "ga:" + profileID, 
  'start-date' => startDate,
  'end-date' => endDate,
  'dimensions' => "ga:day,ga:month",
  'metrics' => "ga:visits",
  'sort' => "ga:month,ga:day" 
})

print visitCount.data.column_headers.map { |c|
  c.name  
}.join("\t")

visitCount.data.rows.each do |r|
  print r.join("\t"), "\n"
end

我花了一整天的时间来完成这项工作。请帮忙。谢谢你的时间。

Solved it !

My Computer clock was for some reason 4 hours late ! Corrected System Time, it lead to no error.

1 - Make Your you solve the SSL Error if you have any by using the Google API Faq.

It took me whole day, so I'm going to leave my solutions so in future no one has to go crazy like I did. 

account_email = '@developer.gserviceaccount.com' 
key_file = 'privatekey.p12' 
key_secret = 'notasecret' 
client = Google::APIClient.new()

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/calendar',
   :issuer => account_email,
   :signing_key => key)

# # Request a token for our service account
 client.authorization.fetch_access_token!
 service = client.discovered_api('calendar', 'v3')

Example to execute something shall be like in similar fashion.

  @event = {
    'summary' => '',
    'location' => 'this is where the location goes',
     'description' => 'desc',
    'start' => {
      'dateTime' => '2013-02-08T10:00:00.000-07:00' # Date with :- offset so (yyyy-mm-dd T hh:mm:ss.000-offset)
    },
    'end' => {
      'dateTime' => '2013-02-08T10:25:00.000-07:00' # Date with :- offset so (yyyy-mm-dd T hh:mm:ss.000-offset)
    }
  }

  # Create event using the json structure 
  result = client.execute(:api_method => service.events.insert,
                          :parameters => {'calendarId' => '**'},
                          :body => JSON.dump(@event),
                          :headers => {'Content-Type' => 'application/json'})
