ошибка входа в систему при получении списка календаря

Question

Я пытаюсь получить основной календарь в моем приложении nodeJS, но его выдача

ошибка входа требуется
код: 401,
Ошибки:
[{domain: 'global',
причина: «требуется»,
сообщение: «Требуется вход в систему»,
locationType: 'header',
location: 'Авторизация'}]}

следующий код

calendar.middleware.js

const {google} = require('googleapis');
const oAuth2Client = new google.auth.OAuth2(
  CLIENT_ID,
  CLIENT_SECRET,
  'http://localhost:8000/api/v1/google/callback' //YOUR_REDIRECT_URL
);
const SCOPES = [
  'https://www.googleapis.com/auth/calendar'
];

const authUrl = oAuth2Client.generateAuthUrl({
  access_type: 'offline',
  scope: SCOPES,
});
module.exports = {
  fetchToken: async function(req, res, next){
    console.log("fetchToken");
    const code = req.query.code;
    try{
        const token = await oAuth2Client.getToken(code);
        req.token = token;
        next();
    }catch(e){
      next(e);
    }
  },

  fetchCalendars: async function(req, res, next){
    console.log("fetchCalendars");
    const token = req.token;
    let cals;
    oAuth2Client.setCredentials(token);
    try{
      const calendar = await google.calendar({version: 'v3', oAuth2Client});
      cals = calendar.calendarList.get({calendarId: 'primary'});
      console.log(cals);
      next();
    }catch(e){
      next(e);
    }
  }
}

маршруты / index.js

...
router.route('api/v1/google/callback').get( calendarMiddleware.fetchToken,
                                      calendarMiddleware.fetchCalendars,
                                      calendarController.googleCallback);

'Требуется вход в систему',

Означает, что вы не правильно аутентифицируете свой запрос.Следующее должно быть близко

const fs = require('fs');
const readline = require('readline');
const {google} = require('googleapis');

// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/calendar'];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = 'token.json';

// Load client secrets from a local file.
fs.readFile('credentials.json', (err, content) => {
  if (err) return console.log('Error loading client secret file:', err);
  // Authorize a client with credentials, then call the Google Calendar API.
  authorize(JSON.parse(content), fetchCalendars);
});

/**
 * 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) {
  const {client_secret, client_id, redirect_uris} = credentials.installed;
  const oAuth2Client = new google.auth.OAuth2(
      client_id, client_secret, redirect_uris[0]);

  // Check if we have previously stored a token.
  fs.readFile(TOKEN_PATH, (err, token) => {
    if (err) return getAccessToken(oAuth2Client, callback);
    oAuth2Client.setCredentials(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 for the authorized client.
 */
function getAccessToken(oAuth2Client, callback) {
  const authUrl = oAuth2Client.generateAuthUrl({
    access_type: 'offline',
    scope: SCOPES,
  });
  console.log('Authorize this app by visiting this url:', authUrl);
  const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout,
  });
  rl.question('Enter the code from that page here: ', (code) => {
    rl.close();
    oAuth2Client.getToken(code, (err, token) => {
      if (err) return console.error('Error retrieving access token', err);
      oAuth2Client.setCredentials(token);
      // Store the token to disk for later program executions
      fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
        if (err) return console.error(err);
        console.log('Token stored to', TOKEN_PATH);
      });
      callback(oAuth2Client);
    });
  });
}

/**
 * Lists the names and IDs of up to 10 files.
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */
function fetchCalendars(auth) {
  const calendar = google.calendar({version: 'v3', auth});
  cals = calendar.calendarList.get({calendarId: 'primary'}), (err, res) => {
    if (err) return console.log('The API returned an error: ' + err);
    const items = res.items;
    if (items.length) {
      console.log('Calendar:');
      items.map((calendarList) => {
        console.log(`${calendarList.description} (${calendarList.id})`);
      });
    } else {
      console.log('No files found.');
    }
  });
}
