I seguenti esempi di codice, che utilizzano la libreria client delle API di Google per Ruby, sono disponibili per YouTube Analytics API. Puoi scaricare questi esempi di codice dalla cartella ruby del repository di esempio delle API di YouTube su GitHub.
Autorizzare una richiesta
L'esempio di codice riportato di seguito esegue l'autorizzazione OAuth 2.0 controllando la presenza di un file locale contenente le credenziali di autorizzazione. Se il file non è presente, lo script apre un browser e attende una risposta, quindi salva le credenziali restituite localmente.

require 'google/api_client/client_secrets'
require 'json'
require 'launchy'

<html>
<head>
<title>OAuth 2 Flow Complete</title>
</head>
<body>
You have successfully completed the OAuth 2 flow. Please close this browser window and return to your program.
</body>
</html>

FILE_POSTFIX = '-oauth2.json'
# Small helper for the sample apps for performing OAuth 2.0 flows from the command
# line. Starts an embedded server to handle redirects.

def initialize(scope)
credentials = Google::APIClient::ClientSecrets.load
@authorization = Signet::OAuth2::Client.new(
:authorization_uri => credentials.authorization_uri,
:token_credential_uri => credentials.token_credential_uri,
:client_id => credentials.client_id,
:client_secret => credentials.client_secret,
:redirect_uri => credentials.redirect_uris.first,
:scope => scope
)
end
# Request authorization. Checks to see if a local file with credentials is present, and uses that.
# Otherwise, opens a browser and waits for response, then saves the credentials locally.
def authorize
credentialsFile = $0 + FILE_POSTFIX
if File.exist? credentialsFile
File.open(credentialsFile, 'r') do |file|
credentials = JSON.load(file)
@authorization.access_token = credentials['access_token']
@authorization.client_id = credentials['client_id']

@authorization.fetch_access_token!
save(credentialsFile)

end

# Exchange the auth code & quit
req = Rack::Request.new(env)
auth.code = req['code']
auth.fetch_access_token!
server.stop()

}
end
Launchy.open(url)

save(credentialsFile)
end

end

File.open(credentialsFile, 'w', 0600) do |file|
json = JSON.dump({
:access_token => @authorization.access_token,
:client_id => @authorization.client_id,
:client_secret => @authorization.client_secret,
:refresh_token => @authorization.refresh_token,
:token_expiry => @authorization.expires_at
})
file.write(json)
end
end
end
Recuperare i 10 video principali per numero di visualizzazioni
Questo esempio chiama il metodo reports.query dell'API per recuperare i dati di YouTube Analytics.
Per impostazione predefinita, il report recupera i primi 10 video in base al numero di visualizzazioni e restituisce diverse metriche per questi video, ordinando i risultati in ordine inverso per numero di visualizzazioni. Impostando i parametri della riga di comando, puoi utilizzare lo stesso codice per recuperare anche altri report.
