Przy pierwszym uruchomieniu próbki pojawi się prośba o autoryzację dostępu:
Przykładowy kod próbuje otworzyć nowe okno lub kartę w przeglądarce domyślnej.
Jeśli to się nie uda, skopiuj adres URL z konsoli i otwórz go ręcznie w przeglądarce.
Jeśli nie zalogujesz się na konto Google, poprosimy Cię o to. Jeśli logujesz się na kilka kont Google, pojawi się prośba o wybranie jednego konta do autoryzacji.
Kliknij przycisk Akceptuję.
Skopiuj otrzymany kod, wklej go w wierszu poleceń i naciśnij Enter. Kod może pojawić się w adresie URL strony, na którą przekierujemy Cię po przyznaniu autoryzacji:

Install the Google API client library using `gem install google-api-client`. A sample `quickstart.rb` file is then created and populated. Finally, the `ruby quickstart.rb` command runs the script, prompting for authorization which stores credentials for future use. This script retrieves and prints basic channel information for GoogleDevelopers.\n"],null,["# Ruby Quickstart\n\nComplete the steps described in the rest of this page, and in about five minutes\nyou'll have a simple Ruby command-line application that makes requests to the\nYouTube Data API.\nThe sample code used in this guide retrieves the `channel` resource for the GoogleDevelopers YouTube channel and prints some basic information from that resource.\n\nPrerequisites\n-------------\n\nTo run this quickstart, you'll need:\n\n- Ruby 2.0 or greater.\n- Access to the internet and a web browser.\n- A Google account.\n\nStep 1: Turn on the YouTube Data API\n------------------------------------\n\n1. Use\n [this wizard](https://console.developers.google.com/start/api?id=youtube)\n to create or select a project in the Google Developers Console and\n automatically turn on the API. Click **Continue** , then\n **Go to credentials**.\n\n2. On the **Create credentials** page, click the\n **Cancel** button.\n\n3. At the top of the page, select the **OAuth consent screen** tab.\n Select an **Email address** , enter a **Product name** if not\n already set, and click the **Save** button.\n\n4. Select the **Credentials** tab, click the **Create credentials**\n button and select **OAuth client ID**.\n\n5. Select the application type **Other** , enter the name\n \"YouTube Data API Quickstart\", and click the **Create** button.\n\n6. Click **OK** to dismiss the resulting dialog.\n\n7. Click the file_download\n (Download JSON) button to the right of the client ID.\n\n8. Move the downloaded file to your working directory and rename it\n `client_secret.json`.\n\nStep 2: Install the Google Client Library\n-----------------------------------------\n\nRun the following command to install the library: \n\n gem install google-api-client\n\nSee the library's [installation\npage](/api-client-library/ruby/start/installation) for the alternative\ninstallation options.\n\nStep 3: Set up the sample\n-------------------------\n\nCreate a file named `quickstart.rb` in your working directory and copy in the\nfollowing code:\n\n\n```ruby\n# Sample Ruby code for user authorization\n\nrequire 'rubygems'\ngem 'google-api-client', '\u003e0.7'\nrequire 'google/apis'\nrequire 'google/apis/youtube_v3'\nrequire 'googleauth'\nrequire 'googleauth/stores/file_token_store'\n\nrequire 'fileutils'\nrequire 'json'\n\n# REPLACE WITH VALID REDIRECT_URI FOR YOUR CLIENT\nREDIRECT_URI = 'http://localhost'\nAPPLICATION_NAME = 'YouTube Data API Ruby Tests'\n\n# REPLACE WITH NAME/LOCATION OF YOUR client_secrets.json FILE\nCLIENT_SECRETS_PATH = 'client_secret.json'\n\n# REPLACE FINAL ARGUMENT WITH FILE WHERE CREDENTIALS WILL BE STORED\nCREDENTIALS_PATH = File.join(Dir.home, '.credentials',\n \"youtube-quickstart-ruby-credentials.yaml\")\n\n# SCOPE FOR WHICH THIS SCRIPT REQUESTS AUTHORIZATION\nSCOPE = Google::Apis::YoutubeV3::AUTH_YOUTUBE_READONLY\n\ndef authorize\n FileUtils.mkdir_p(File.dirname(CREDENTIALS_PATH))\n\n client_id = Google::Auth::ClientId.from_file(CLIENT_SECRETS_PATH)\n token_store = Google::Auth::Stores::FileTokenStore.new(file: CREDENTIALS_PATH)\n authorizer = Google::Auth::UserAuthorizer.new(\n client_id, SCOPE, token_store)\n user_id = 'default'\n credentials = authorizer.get_credentials(user_id)\n if credentials.nil?\n url = authorizer.get_authorization_url(base_url: REDIRECT_URI)\n puts \"Open the following URL in the browser and enter the \" +\n \"resulting code after authorization\"\n puts url\n code = gets\n credentials = authorizer.get_and_store_credentials_from_code(\n user_id: user_id, code: code, base_url: REDIRECT_URI)\n end\n credentials\nend\n\n# Initialize the API\nservice = Google::Apis::YoutubeV3::YouTubeService.new\nservice.client_options.application_name = APPLICATION_NAME\nservice.authorization = authorize\n\n# Sample ruby code for channels.list\n\ndef channels_list_by_username(service, part, **params)\n response = service.list_channels(part, params).to_json\n item = JSON.parse(response).fetch(\"items\")[0]\n\n puts (\"This channel's ID is #{item.fetch(\"id\")}. \" +\n \"Its title is '#{item.fetch(\"snippet\").fetch(\"title\")}', and it has \" +\n \"#{item.fetch(\"statistics\").fetch(\"viewCount\")} views.\")\nend\n\nchannels_list_by_username(service, 'snippet,contentDetails,statistics', for_username: 'GoogleDevelopers')\nhttps://github.com/youtube/api-samples/blob/07263305b59a7c3275bc7e925f9ce6cabf774022/ruby/quickstart.rb\n```\n\n\u003cbr /\u003e\n\nStep 4: Run the sample\n----------------------\n\nRun the sample using the following command: \n\n ruby quickstart.rb\n\nThe first time you run the sample, it will prompt you to authorize access:\n\n1. The sample attempts to open a new window or tab in your default browser.\n If this fails, copy the URL from the console and manually open it in\n your browser.\n\n If you are not already logged into your Google account, you are\n prompted to log in. If you are logged into multiple Google accounts,\n you are asked to select one account to use for the authorization.\n2. Click the **Accept** button.\n3. Copy the code you're given, paste it into the command-line prompt, and press\n **Enter**. The code may appear in the URL of the page you are redirected to\n after granting authorization:\n\n ```\n http://localhost/?code=4/nr_1TspmmQPFyifh7nz...OFo#\n ```\n\nIt worked! **Great!** Check out the further reading section below to learn more.\nI got an error **Bummer.** Thanks for letting us know and we'll work to fix this quickstart.\n\nNotes\n-----\n\n- Authorization information is stored on the file system, so subsequent executions will not prompt for authorization.\n- The authorization flow in this example is designed for a command-line application. For information on how to perform authorization in a web application, see [Using OAuth 2.0 for Web Server Applications](/youtube/v3/guides/auth/server-side-web-apps).\n\nFurther reading\n---------------\n\n- [Google Developers Console help documentation](/console/help/new)\n- [Google APIs Client for Ruby documentation](/api-client-library/ruby)\n- [YouTube Data API reference documentation](/youtube/v3/docs)"]]
