API 키 만들기
사용자 승인이 필요하지 않은 API 요청을 만드는 데 API 키를 사용합니다. 예를 들어 공개 YouTube 채널에 관한 정보를 가져오는 데는 사용자 승인이 필요하지 않습니다.
OAuth 2.0 클라이언트 ID 만들기
애플리케이션 유형을 웹 애플리케이션으로 설정합니다. 사용자 승인이 필요한 요청에는 OAuth 2.0 사용자 인증 정보를 사용해야 합니다. 예를 들어 현재 인증된 사용자의 YouTube 채널에 관한 정보를 가져오려면 사용자 승인이 필요합니다.
측면 패널의 API 탐색기 위젯을 사용하여 GoogleDevelopers YouTube 채널에 관한 정보를 가져오는 샘플 코드를 가져옵니다. 이 요청은 API 키를 사용하여 애플리케이션을 식별하며, 사용자 승인이나 샘플을 실행하는 사용자의 특별한 권한이 필요하지 않습니다.

This quickstart actually explains how to make two API\nrequests:\n\n1. You will use an API key, which identifies your application, to retrieve information about the GoogleDevelopers YouTube channel.\n2. You will use an OAuth 2.0 client ID to submit an *authorized* request that retrieves information about your own YouTube channel.\n\n| **Note:** More generally, you can follow the instructions for the first example for any use case that uses an API key or the instructions for the second example for any use case that requires authorization using OAuth 2.0. See the [use cases and code samples tool](/youtube/v3/code_samples/code_snippets) for more examples.\n\nPrerequisites\n-------------\n\nTo run this quickstart, you'll need:\n\n- Python 2.4 or greater (to provide a web server)\n- Access to the internet and a web browser.\n- A Google account.\n\nStep 1: Set up your project and credentials\n-------------------------------------------\n\nCreate or select a project in the [API Console](https://console.cloud.google.com/). Complete the following tasks in the API Console for your project:\n\n1. In the [library panel](https://console.developers.google.com/apis/library),\n search for the YouTube Data API v3. Click into the listing for that API and\n make sure the API is enabled for your project.\n\n2. In the [credentials\n panel](https://console.developers.google.com/apis/credentials),\n create two credentials:\n\n 1. **Create an API key**\n You will use the API key to make API requests that do\n not require user authorization. For example, you do not need user\n authorization to retrieve information about a public YouTube channel.\n\n 2. **Create an OAuth 2.0 client ID**\n\n Set the application type to **Web application**. You need to use OAuth\n 2.0 credentials for requests that require user authorization. For\n example, you need user authorization to retrieve information about the\n currently authenticated user's YouTube channel.\n\n In the **Authorized JavaScript origins** field, enter the URL\n `http://localhost:8000`. You can leave the **Authorized redirect URIs**\n field blank.\n\nStep 2: Set up and run the sample\n---------------------------------\n\nUse the APIs Explorer widget in the side panel to obtain sample code for\nretrieving information about the GoogleDevelopers YouTube channel. This request\nuses an API key to identify your application, and it does not require user\nauthorization or any special permissions from the user running the sample.\n\n1. Open the documentation for the API's [channels.list](/youtube/v3/docs/channels/list) method.\n2. On that page, the \"Common use cases\" section contains a table that explains\n several common ways that the method is used. The first listing in the table\n is for listing results by channel ID.\n\n Click the code symbol for the first listing to open and populate the\n fullscreen APIs Explorer.\n\n3. The left side of the fullscreen APIs Explorer shows the following:\n\n 1. Below the **Request parameters** header, there is a list of parameters\n that the method supports. The `part` and `id` parameter values should\n be set. The `id` parameter value, `UC_x5XG1OV2P6uZZ5FSM9Ttw`, is the\n ID for the GoogleDevelopers YouTube channel.\n\n 2. Below the parameters, there is a section named **Credentials** . The\n pulldown menu in that section should display the value **API key**. The\n APIs Explorer uses demo credentials by default to make it easier to get\n started. But you'll use your own API key to run the sample locally.\n\n4. The right side of the fullscreen APIs Explorer shows tabs with code samples\n in different languages. Select the **JavaScript** tab.\n\n5. Copy the code sample and save it in a file named\n `example.html`.\n\n6. In the sample that you downloaded, find the `YOUR_API_KEY` string and\n replace that with the API key that you created in step 1 of this quickstart.\n\n7. Start the web server using the following command from your working\n directory:\n\n ### Python 2.x\n\n python -m SimpleHTTPServer 8000\n\n ### Python 3.x\n\n python -m http.server 8000\n\n8. Open the example.html file in your browser. Also open the browser's\n developer tools, such as the \"Developer Tools\" in the Chrome browser.\n\n 1. Click the **load** button on the page to load the Google APIs Client\n Library for JavaScript. After you click the button, the developer\n console should display a note indicating that the GAPI client loaded.\n\n 2. Click the **execute** button to send the API request. The developer's\n console should then display the API response.\n\nStep 3: Run an authorized request\n---------------------------------\n\nIn this step, you'll modify your code sample so that instead of retrieving\ninformation about the GoogleDevelopers YouTube channel, it retrieves information\nabout *your* YouTube channel. This request does require user authorization.\n\n1. Go back to the documentation for the API's\n [channels.list](/youtube/v3/docs/channels/list) method.\n\n2. In the \"Common use cases\" section, click the code symbol for the third\n listing in the table. That use case is to call the `list` method for \"my\n channel.\"\n\n3. Again, in the left side of the fullscreen APIs Explorer, you will see a\n list of parameters followed by the **Credentials** section. However, there\n are two changes from the example where you retrieved information about the\n GoogleDevelopers channel:\n\n 1. In the parameters section, instead of the `id` parameter value being\n set, the `mine` parameter value should be set to `true`. This instructs\n the API server to retrieve information about the currently authenticated\n user's channel.\n\n 2. In the **Credentials** section, the pulldown menu should select the\n option for **Google OAuth 2.0**.\n\n In addition, if you click the **Show scopes** link, the\n **https://www.googleapis.com/auth/youtube.readonly** scope should be\n checked.\n\n4. As with the previous example, select the **JavaScript** tab,\n copy the code sample, and save it to `example.html`.\n\n In the code, find the `YOUR_CLIENT_ID` string and replace it with the\n client ID that you created in step 1 of this quickstart.\n5. Start the web server using the following command from your working\n directory:\n\n ### Python 2.x\n\n python -m SimpleHTTPServer 8000\n\n ### Python 3.x\n\n python -m http.server 8000\n\n6. Go to `http://localhost:8000/example.html` file in your browser.\n Open the browser's developer tools, such as the \"Developer Tools\" in the\n Chrome browser.\n\n7. Click the **authorize and load** button on the page to load the Google\n APIs Client Library for JavaScript and initiate the authorization flow.\n You should be prompted to grant the application permission to read data\n from your YouTube account.\n\n If you grant the permission, the developer's console should display\n messages indicating that sign-in was successful and that the API client\n loaded.\n8. Click the **execute** button to send the API request. The developer's\n console should then display the API response.\n\nFurther reading\n---------------\n\n- [Google Developers Console help documentation](/console/help/new)\n- [Google APIs Client Library for JavaScript documentation](/api-client-library/javascript)\n- [YouTube Data API reference documentation](/youtube/v3/docs)"]]
