创建事件时，Google Calendar API v3 服务帐户不发送通知

Question

我正在尝试使用 Google 服务帐户创建日历活动（在其自己的日历中）并邀请一些与会者。

当我使用服务帐户和 JWT 身份验证创建事件时，事件已成功创建，但受邀者未收到电子邮件通知 - 请参阅下面的代码。如果我使用客户帐户，则会发送电子邮件通知，但我不想诉诸于此。

难道我做错了什么？

var google = require('googleapis');
var SCOPES = ['https://www.googleapis.com/auth/calendar'];

var key = require("./API-Project-key.json");
var jwtClient = new google.auth.JWT(key.client_email, null, key.private_key, SCOPES, null);

jwtClient.authorize(function(err) {
    if (err) {
        console.log(err);
        return;
    }
    createEvent(jwtClient);

});

/**
 * @param {google.auth.OAuth2} auth An authorized OAuth2 client.
 */
function createEvent (auth) {
    var calendar = google.calendar('v3');


    var event = {
        'summary': 'Test Event',
        'location': 'London, UK',
        'description': 'This is a sample event',
        'start': {
            'dateTime': '2016-03-15T20:00:00',
            'timeZone': 'Europe/London',
        },
        'end': {
            'dateTime': '2016-03-15T21:00:00',
            'timeZone': 'Europe/London',
        },
        'attendees': [
            {'email': 'myemail@mydomain.com'}
        ]
    };

    calendar.events.insert({
        auth: auth,
        calendarId: 'primary',
        sendNotifications: true,
        resource: event
    }, function (err, event) {
        if (err) {
            return console.log(err, event);
        }
        return console.log(event);
    });
}

“sendNotifications”现已弃用。您需要将其更改为“sendUpdates”并传入参数“all”，如下所示：

calendar.events.insert({
    auth: auth,
    calendarId: 'primary',
    sendUpdates:'all',
    resource: event
}, function (err, event) {
    if (err) {
        return console.log(err, event);
    }
    return console.log(event);
});

来自谷歌文档：

Acceptable values are:

"all": Notifications are sent to all guests.
"externalOnly": Notifications are sent to non-Google Calendar guests only.
"none": No notifications are sent. This value should only be used for migration use cases (note that in most migration cases the import method should be used).
