Question

我正在制作一个搜索 YouTube 视频并创建包含这些视频的播放列表的应用程序。

我已经想通了如何使用提供的 API 键搜索视频，但完全不知道如何以用户身份进行操作。起初，我以为我可以只使用一个服务帐户来托管所有播放列表，但我很快了解到 YouTube 不支持。

我的最终目标是在我的个人 YouTube 帐户上创建一个播放列表，因此我希望将该帐户硬编码到其中。

我正在努力将它从使用服务帐户更改为我的个人帐户。我见过的许多其他解决方案都使用带有前端组件的快速服务器，但我都没有。

  import { google } from 'googleapis';
  import fs from 'fs';

  const config = JSON.parse(fs.readFileSync('config.json', 'utf8'));

  const key = require('./credentials.json');

  const scopes = "https://www.googleapis.com/auth/youtube";

  const jwt = new google.auth.JWT(key.client_email, null, key.private_key, scopes);

  jwt.authorize((err, response) => {

     const yt = google.youtube({
        version: 'v3',
        auth: jwt,
     });

     yt.search.list({
        part: 'snippet',
        q: 'study music | zen music -livestream -live',
        maxResults: 1,
     }, (err, data) => {

        if (err) console.error(err);

        if (data) {

           console.log(data.data.items);
           // TODO: create playlist with these items

        }

     });

  });

目前正在使用服务帐号搜索视频。我还没有完成播放列表创建部分，因为它会在我使用服务帐户时不断出错。

YouTube API 不支持服务帐户。您将需要使用 Oauth2 并保存刷新令牌。然后，您可以在需要时使用刷新令牌请求新的访问令牌。

我推荐关注quickstart

var fs = require('fs');
var readline = require('readline');
var {google} = require('googleapis');
var OAuth2 = google.auth.OAuth2;

// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/youtube-nodejs-quickstart.json
var SCOPES = ['https://www.googleapis.com/auth/youtube.readonly'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
    process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + 'youtube-nodejs-quickstart.json';

// Load client secrets from a local file.
fs.readFile('client_secret.json', function processClientSecrets(err, content) {
  if (err) {
    console.log('Error loading client secret file: ' + err);
    return;
  }
  // Authorize a client with the loaded credentials, then call the YouTube API.
  authorize(JSON.parse(content), getChannel);
});

/**
 * Create an OAuth2 client with the given credentials, and then execute the
 * given callback function.
 *
 * @param {Object} credentials The authorization client credentials.
 * @param {function} callback The callback to call with the authorized client.
 */
function authorize(credentials, callback) {
  var clientSecret = credentials.installed.client_secret;
  var clientId = credentials.installed.client_id;
  var redirectUrl = credentials.installed.redirect_uris[0];
  var oauth2Client = new OAuth2(clientId, clientSecret, redirectUrl);

  // Check if we have previously stored a token.
  fs.readFile(TOKEN_PATH, function(err, token) {
    if (err) {
      getNewToken(oauth2Client, callback);
    } else {
      oauth2Client.credentials = JSON.parse(token);
      callback(oauth2Client);
    }
  });
}

/**
 * Get and store new token after prompting for user authorization, and then
 * execute the given callback with the authorized OAuth2 client.
 *
 * @param {google.auth.OAuth2} oauth2Client The OAuth2 client to get token for.
 * @param {getEventsCallback} callback The callback to call with the authorized
 *     client.
 */
function getNewToken(oauth2Client, callback) {
  var authUrl = oauth2Client.generateAuthUrl({
    access_type: 'offline',
    scope: SCOPES
  });
  console.log('Authorize this app by visiting this url: ', authUrl);
  var rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
  });
  rl.question('Enter the code from that page here: ', function(code) {
    rl.close();
    oauth2Client.getToken(code, function(err, token) {
      if (err) {
        console.log('Error while trying to retrieve access token', err);
        return;
      }
      oauth2Client.credentials = token;
      storeToken(token);
      callback(oauth2Client);
    });
  });
}

/**
 * Store token to disk be used in later program executions.
 *
 * @param {Object} token The token to store to disk.
 */
function storeToken(token) {
  try {
    fs.mkdirSync(TOKEN_DIR);
  } catch (err) {
    if (err.code != 'EEXIST') {
      throw err;
    }
  }
  fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
    if (err) throw err;
    console.log('Token stored to ' + TOKEN_PATH);
  });
  console.log('Token stored to ' + TOKEN_PATH);
}

/**
 * Lists the names and IDs of up to 10 files.
 *
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */
function getChannel(auth) {
  var service = google.youtube('v3');
  service.channels.list({
    auth: auth,
    part: 'snippet,contentDetails,statistics',
    forUsername: 'GoogleDevelopers'
  }, function(err, response) {
    if (err) {
      console.log('The API returned an error: ' + err);
      return;
    }
    var channels = response.data.items;
    if (channels.length == 0) {
      console.log('No channel found.');
    } else {
      console.log('This channel\'s ID is %s. Its title is \'%s\', and ' +
                  'it has %s views.',
                  channels[0].id,
                  channels[0].snippet.title,
                  channels[0].statistics.viewCount);
    }
  });
}
