问题
I am realising example from Google Calendar API instruction web page. I put the code into example.js file and start it with node example.js in command line.
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';
// 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);
});
/**
* 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 **strong text**{
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);
}
}
});
}
everthing is working allrigth. But when I try to insert event to Google calendar with this code.
authorize(JSON.parse(content), addEvent);
function addEvent(auth) {
var event = {
'summary': 'Google I/O 2015',
'location': '800 Howard St., San Francisco, CA 94103',
'description': 'A chance to hear more about Google\'s developer products.',
'start': {
'dateTime': '2015-05-28T09:00:00-07:00',
'timeZone': 'America/Los_Angeles',
},
'end': {
'dateTime': '2015-05-28T17:00:00-07:00',
'timeZone': 'America/Los_Angeles',
},
'recurrence': [
'RRULE:FREQ=DAILY;COUNT=2'
],
'attendees': [
{'email': 'lpage@example.com'},
{'email': 'sbrin@example.com'},
],
'reminders': {
'useDefault': false,
'overrides': [
{'method': 'email', 'minutes': 24 * 60},
{'method': 'popup', 'minutes': 10},
],
},
};
var calendar = google.calendar('v3');
calendar.events.insert({
auth: auth,
calendarId: 'primary',
resource: event,
}, function(err, event) {
if (err) {
console.log('There was an error contacting the Calendar service: ' + err);
return;
}
console.log('Event created: %s', event.htmlLink);
});
I invariably get:
There was an error contacting the Calendar service: Error: Missing end time.
What I am doing wrong.
回答1:
I had the same issue. I had a version of the google-auth-library that wasn't compatible with the most recent googleapis version. Check your versions - you might need to upgrade and migrate over your google-auth-library which is why the example above doesnt work for you.
Here's the edits you might have to do if this is your issue: https://github.com/google/google-auth-library-nodejs/releases/tag/v1.0.0
回答2:
I am currently having the same error as this one, using codes from examples and from @noogui. I found this library working as expected although requires a lot of configuration node-google-calendar.
I also hope Google Calendar API will work soon.

Try mine:
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';
// 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), insertEvent);
});
/**

// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, function(err, token) {

oauth2Client.credentials = JSON.parse(token);

function getNewToken(oauth2Client, callback) {

throw err;
}
}
fs.writeFile(TOKEN_PATH, JSON.stringify(token));
console.log('Token stored to ' + TOKEN_PATH);
}
function insertEvent(auth) {
var event = {

var calendar = google.calendar('v3');
calendar.events.insert({
auth: auth,
calendarId: 'primary',
resource: event,
}, function(err, event) {
if (err) {
console.log('There was an error contacting the Calendar service: ' + err);
return;
}
console.log('Event created: %s', event.htmlLink);
});
}
Proof the sample Quickstart is working. Events are inserted in my calendar:

googleapis@24.0.0 and google-auth-library@0.12.0 worked for me
