spotify-web-api-node - WebapiError：未经授权

Question

var SpotifyWebApi = require('spotify-web-api-node');

var spotifyApi = new SpotifyWebApi({
    clientId : 'xxx',
    clientSecret : 'xxx',
    redirectUri : 'https://example.com/callback'
});

spotifyApi.getTrack('2q8eudK0r9ImgCB1XhFfxG').then(function(data) {
    console.log(data);
});

我的代码有效，但 1 个月后出现此错误。

(node:12824) UnhandledPromiseRejectionWarning: 未处理的承诺 拒绝（拒绝ID：1）：WebapiError：未经授权

（节点：12824） DeprecationWarning：不推荐使用未处理的承诺拒绝。在 未来，未处理的承诺拒绝将终止 具有非零退出代码的 Node.js 进程。

根据this issue需要设置访问令牌。

spotifyApi.setAccessToken('myAccessToken');

另外，请看这里：https://github.com/thelinmichael/spotify-web-api-node#setting-credentials

// Set necessary parts of the credentials on the constructor
var spotifyApi = new SpotifyWebApi({
  clientId : 'myClientId',
  clientSecret : 'myClientSecret'
});

// Get an access token and 'save' it using a setter
spotifyApi.clientCredentialsGrant()
  .then(function(data) {
    console.log('The access token is ' + data.body['access_token']);
    spotifyApi.setAccessToken(data.body['access_token']);
  }, function(err) {
    console.log('Something went wrong!', err);
  });

// Get tracks in a playlist
spotifyApi.getPlaylistTracks('thelinmichael', '3ktAYNcRHpazJ9qecm3ptn', { 'offset' : 1, 'limit' : 5, 'fields' : 'items' })
  .then(function(data) {
    console.log('The playlist contains these tracks', data.body);
  }, function(err) {
    console.log('Something went wrong!', err);
  });
