Die folgenden Codebeispiele, die die Google APIs-Clientbibliothek für Ruby verwenden, sind für YouTube Analytics API verfügbar. Sie können diese Codebeispiele aus dem Ordner ruby des Beispiel-Repositorys für YouTube APIs auf GitHub herunterladen.
Anfrage autorisieren
Mit dem folgenden Codebeispiel wird die OAuth 2.0-Autorisierung durchgeführt. Dabei wird geprüft, ob eine lokale Datei mit Autorisierungsanmeldedaten vorhanden ist. Ist die Datei nicht vorhanden, öffnet das Skript einen Browser, wartet auf eine Antwort und speichert die zurückgegebenen Anmeldedaten lokal.
require 'google/api_client' require 'google/api_client/client_secrets' require 'json' require 'launchy' require 'thin' RESPONSE_HTML = <<stop <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> stop 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. class CommandLineOAuthHelper 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.client_secret = credentials['client_secret'] @authorization.refresh_token = credentials['refresh_token'] @authorization.expires_in = (Time.parse(credentials['token_expiry']) - Time.now).ceil if @authorization.expired? @authorization.fetch_access_token! save(credentialsFile) end end else auth = @authorization url = @authorization.authorization_uri().to_s server = Thin::Server.new('0.0.0.0', 8080) do run lambda { |env| # Exchange the auth code & quit req = Rack::Request.new(env) auth.code = req['code'] auth.fetch_access_token! server.stop() [200, {'Content-Type' => 'text/html'}, RESPONSE_HTML] } end Launchy.open(url) server.start() save(credentialsFile) end return @authorization end def save(credentialsFile) 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 Top-10-Videos nach Anzahl der Aufrufe abrufen
In diesem Beispiel wird die Methode reports.query der API aufgerufen, um YouTube Analytics-Daten abzurufen. Standardmäßig ruft der Bericht die Top-10-Videos anhand der Anzahl der Aufrufe ab. Dabei werden mehrere Messwerte für diese Videos zurückgegeben. Die Ergebnisse werden in umgekehrter Reihenfolge nach der Anzahl der Aufrufe sortiert. Wenn Sie Befehlszeilenparameter festlegen, können Sie denselben Code verwenden, um auch andere Berichte abzurufen.
