javascript - 如何使用 Node.js 从 google calendar API 获取当前一年的所有假期？

Question

以下代码从日历 API 获取事件，但我想获取当年的假期，请帮助我..

var fs = require('fs');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');

var SCOPES = ['https://www.googleapis.com/auth/calendar.readonly'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
   process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + 'calendar-api-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
   // Google Calendar API.
   console.log("content " + content);
   authorize(JSON.parse(content), listEvents);
});

/**
 * 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 auth = new googleAuth();
   var oauth2Client = new auth.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));
   console.log('Token stored to ' + TOKEN_PATH);
}

/**
 * Lists the next 10 events on the user's primary calendar.
 *
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */
function listEvents(auth) {
   var calendar = google.calendar('v3');
   calendar.events.list({
      auth: auth,
      calendarId: 'primary',
      timeMin: (new Date()).toISOString(),
      maxResults: 10,
      singleEvents: true,
      orderBy: 'startTime'
   }, function (err, response) {
      if (err) {
         console.log('The API returned an error: ' + err);
         return;
      }
      var events = response.items;
      if (events.length == 0) {
         console.log('No upcoming events found.');
      } else {
         console.log('Upcoming 10 events:');
         for (var i = 0; i < events.length; i++) {
            var event = events[i];
            var start = event.start.dateTime || event.start.date;
            console.log('%s - %s', start, event.summary);
         }
      }
   });
}

我想从 Google 日历 API 获取整个今年的假期。如果有人知道，请给我解决方案。

有公共(public)假期的日历，您只需找到您想要的日历 ID。

最好的方法是进入您的 Google 日历，在左侧底部显示其他日历，点击下拉菜单选择浏览有趣的日历，有一个很大的列表。

将日历添加到您的 Google 日历，点击旁边的箭头并检查日历设置。它会告诉您日历的 ID en.danish#holiday@group.v.calendar.google.com、en.uk#holiday@group.v.calendar.google.com

甚至还有基督教节日、犹太节日、东正教节日。

然后您可以在代码中使用该日历 ID。
