我已按照https://developers.google.com/google-apps/calendar/quickstart/nodejs和https://developers.google.com/google-apps/calendar/create-events的所有说明进行操作。我得到了我的client_secret.json和calendar-nodejs-quickstart.json,但我还没有工作。 这是我的代码:
var fs = require('fs');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-nodejs-quickstart.json
var SCOPES = ['https://www.googleapis.com/auth/calendar'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + './calendar-nodejs-quickstart.json';
console.log(TOKEN_PATH);
// 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.
authorize(JSON.parse(content), listEvents);
authorize(JSON.parse(content), insertEvent);
});
/**

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);
}
});
}
/**

function getNewToken(oauth2Client, callback) {

access_type: 'offline',

console.log('Authorize this app by visiting this url: ', authUrl);
var rl = readline.createInterface({

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);
});
});
}
/**

function storeToken(token) {
try {
fs.mkdirSync(TOKEN_DIR);

if (err.code != 'EEXIST') {
throw err;
}
}
fs.writeFile(TOKEN_PATH, JSON.stringify(token));
console.log('Token stored to ' + TOKEN_PATH);
}
/**

*/
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);

}
listEvents()方法可以使用但不能使用insertEvent。它返回错误:
联系日历服务时出错:错误:缺少结束 时间。
该指令说“更改范围并删除任何存储的凭据”。我也是这样做的。但我只是不知道代码仍然无效
