如何将Spotify Web API网站转换为Phonegap应用程序？

Question

我使用Spotify Web API创建了一个网站，并希望以此创建一个应用程序。我的网站存在一个html文件，Javascript文件和许多插件。在我的网站上，您可以使用Spotify登录并播放曲目。当前，它正在本地服务器上运行。本地主机：8888

这是JavaScript代码：

/**
 * This is an example of a basic node.js script that performs
 * the Authorization Code oAuth2 flow to authenticate against
 * the Spotify Accounts.
 *
 * For more information, read
 * https://developer.spotify.com/web-api/authorization- 
 guide/#authorization_code_flow
 */

var express = require('express'); // Express web server framework
var request = require('request'); // "Request" library
var cors = require('cors');
var querystring = require('querystring');
var cookieParser = require('cookie-parser');

var client_id = '********'; // Your client id
var client_secret = '********'; // Your secret
var redirect_uri = 'http://localhost:8888/callback'; // Your redirect uri

/**
* Generates a random string containing numbers and letters
* @param  {number} length The length of the string
* @return {string} The generated string
*/
var generateRandomString = function(length) {
var text = '';
var possible = 
'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';

for (var i = 0; i < length; i++) {
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text;
};

var stateKey = 'spotify_auth_state';

var app = express();

app.use(express.static(__dirname + '/public'))
.use(cors())
.use(cookieParser());

app.get('/login', function(req, res) {

var state = generateRandomString(16);
res.cookie(stateKey, state);

// your application requests authorization
var scope = 'user-read-private user-read-email user-read-currently-playing 
user-modify-playback-state';
res.redirect('https://accounts.spotify.com/authorize?' +
querystring.stringify({
  response_type: 'code',
  client_id: client_id,
  scope: scope,
  redirect_uri: redirect_uri,
  state: state
}));
});

app.get('/callback', function(req, res) {

// your application requests refresh and access tokens
// after checking the state parameter

var code = req.query.code || null;
var state = req.query.state || null;
var storedState = req.cookies ? req.cookies[stateKey] : null;

if (state === null || state !== storedState) {
res.redirect('/#' +
  querystring.stringify({
    error: 'state_mismatch'
  }));
} else {
res.clearCookie(stateKey);
var authOptions = {
  url: 'https://accounts.spotify.com/api/token',
  form: {
    code: code,
    redirect_uri: redirect_uri,
    grant_type: 'authorization_code'
  },
  headers: {
    'Authorization': 'Basic ' + (new Buffer(client_id + ':' + 
client_secret).toString('base64'))
  },
  json: true
};

request.post(authOptions, function(error, response, body) {
  if (!error && response.statusCode === 200) {

    var access_token = body.access_token,
        refresh_token = body.refresh_token;

    var options = {
      url: 'https://api.spotify.com/v1/me',
      headers: { 'Authorization': 'Bearer ' + access_token },
      json: true
    };

    // use the access token to access the Spotify Web API
    request.get(options, function(error, response, body) {
      console.log(body);
    });

    // we can also pass the token to the browser to make requests from there
    res.redirect('/#' +
      querystring.stringify({
        access_token: access_token,
        refresh_token: refresh_token
      }));
  } else {
    res.redirect('/#' +
      querystring.stringify({
        error: 'invalid_token'
      }));
  }
});
}
});

app.get('/refresh_token', function(req, res) {

// requesting access token from refresh token
var refresh_token = req.query.refresh_token;
var authOptions = {
url: 'https://accounts.spotify.com/api/token',
headers: { 'Authorization': 'Basic ' + (new Buffer(client_id + ':' + 
client_secret).toString('base64')) },
form: {
  grant_type: 'refresh_token',
  refresh_token: refresh_token
},
json: true
};

request.post(authOptions, function(error, response, body) {
if (!error && response.statusCode === 200) {
  var access_token = body.access_token;
  res.send({
    'access_token': access_token
  });
}
});
});

console.log('Listening on 8888');
app.listen(8888);

我需要如何对其进行更改以使其与Phonegap一起使用？
