周期性活动

本文档介绍了如何使用周期性事件及其实例。

创建周期性活动

创建周期性活动类似于创建一个设置了 event 资源的 recurrence 字段的常规（单个）活动。

协议

POST /calendar/v3/calendars/primary/events
...

{
  "summary": "Appointment",
  "location": "Somewhere",
  "start": {
    "dateTime": "2011-06-03T10:00:00.000-07:00",
    "timeZone": "America/Los_Angeles"
  },
  "end": {
    "dateTime": "2011-06-03T10:25:00.000-07:00",
    "timeZone": "America/Los_Angeles"
  },
  "recurrence": [
    "RRULE:FREQ=WEEKLY;UNTIL=20110701T170000Z",
  ],
  "attendees": [
    {
      "email": "attendeeEmail",
      # Other attendee's data...
    },
    # ...
  ],
}

Java

Event event = new Event();

event.setSummary("Appointment");
event.setLocation("Somewhere");

ArrayList<EventAttendee> attendees = new ArrayList<EventAttendee>();
attendees.add(new EventAttendee().setEmail("attendeeEmail"));
// ...
event.setAttendees(attendees);

DateTime start = DateTime.parseRfc3339("2011-06-03T10:00:00.000-07:00");
DateTime end = DateTime.parseRfc3339("2011-06-03T10:25:00.000-07:00");
event.setStart(new EventDateTime().setDateTime(start).setTimeZone("America/Los_Angeles"));
event.setEnd(new EventDateTime().setDateTime(end).setTimeZone("America/Los_Angeles"));
event.setRecurrence(Arrays.asList("RRULE:FREQ=WEEKLY;UNTIL=20110701T170000Z"));

Event recurringEvent = service.events().insert("primary", event).execute();

System.out.println(createdEvent.getId());

.NET

Event event = new Event()
    {
      Summary = "Appointment",
      Location = "Somewhere",
      Start = new EventDateTime() {
          DateTime = new DateTime("2011-06-03T10:00:00.000:-07:00")
          TimeZone = "America/Los_Angeles"
      },
      End = new EventDateTime() {
          DateTime = new DateTime("2011-06-03T10:25:00.000:-07:00")
          TimeZone = "America/Los_Angeles"
      },
      Recurrence = new String[] {
          "RRULE:FREQ=WEEKLY;UNTIL=20110701T170000Z"
      },
      Attendees = new List<EventAttendee>()
          {
            new EventAttendee() { Email: "attendeeEmail" },
            // ...
          }
    };

Event recurringEvent = service.Events.Insert(event, "primary").Fetch();

Console.WriteLine(recurringEvent.Id);

Python

event = {
  'summary': 'Appointment',
  'location': 'Somewhere',
  'start': {
    'dateTime': '2011-06-03T10:00:00.000-07:00',
    'timeZone': 'America/Los_Angeles'
  },
  'end': {
    'dateTime': '2011-06-03T10:25:00.000-07:00',
    'timeZone': 'America/Los_Angeles'
  },
  'recurrence': [
    'RRULE:FREQ=WEEKLY;UNTIL=20110701T170000Z',
  ],
  'attendees': [
    {
      'email': 'attendeeEmail',
      # Other attendee's data...
    },
    # ...
  ],
}

recurring_event = service.events().insert(calendarId='primary', body=event).execute()

print recurring_event['id']

PHP

$event = new Google_Service_Calendar_Event();
$event->setSummary('Appointment');
$event->setLocation('Somewhere');
$start = new Google_Service_Calendar_EventDateTime();
$start->setDateTime('2011-06-03T10:00:00.000-07:00');
$start->setTimeZone('America/Los_Angeles');
$event->setStart($start);
$end = new Google_Service_Calendar_EventDateTime();
$end->setDateTime('2011-06-03T10:25:00.000-07:00');
$end->setTimeZone('America/Los_Angeles');
$event->setEnd($end);
$event->setRecurrence(array('RRULE:FREQ=WEEKLY;UNTIL=20110701T170000Z'));
$attendee1 = new Google_Service_Calendar_EventAttendee();
$attendee1->setEmail('attendeeEmail');
// ...
$attendees = array($attendee1,
                   // ...
                   );
$event->attendees = $attendees;
$recurringEvent = $service->events->insert('primary', $event);

echo $recurringEvent->getId();

Ruby

event = Google::Apis::CalendarV3::Event.new(
  summary: 'Appointment',
  location: 'Somewhere',
  start: {
    date_time: '2011-06-03T10:00:00.000-07:00',
    time_zone:  'America/Los_Angeles'
  },
  end: {
    date_time: '2011-06-03T10:25:00.000-07:00',
    time_zone: 'America/Los_Angeles'
  },
  recurrence: ['RRULE:FREQ=WEEKLY;UNTIL=20110701T170000Z']
  attendees: [
    {
      email: 'attendeeEmail'
    },
    #...
  ]
)
response = client.insert_event('primary', event)
print response.id

访问实例

如需查看给定周期性事件的所有实例，您可以使用 events.instances() 请求。

默认情况下，events.list() 请求仅返回单个事件、周期性事件和异常；系统不会返回非异常的实例。如果 singleEvents 参数设置为 true，则结果中会显示所有单个实例，但底层周期性事件不会。当拥有有空/忙碌权限的用户查询 events.list() 时，其行为就像 singleEvent 为 true 一样。如需详细了解访问控制列表规则，请参阅 Acl。

单个实例类似于单个事件。与父周期性事件不同，实例未设置 recurrence 字段。

以下事件字段特定于实例：

recurringEventId - 此实例所属的父级周期性事件的 ID
originalStartTime - 此实例启动时间取决于父级周期性事件中的周期性数据。如果重新安排实例，这可能与实际 start 时间不同。它可唯一识别周期性活动系列中的实例，即使该实例已移动也是如此。

修改或删除实例

如需修改单个实例（创建异常），客户端应用必须先检索该实例，然后向该实例发送包含经过更新数据的经过授权的 PUT 请求，以更新该实例。网址格式如下：

https://www.googleapis.com/calendar/v3/calendars/calendarId/events/instanceId

使用适当的值代替 calendarId 和 instanceId。

注意：特殊 calendarId 值 primary 可用于指经过身份验证的用户的主日历。

成功后，服务器会返回包含更新实例的 HTTP 200 OK 状态代码。以下示例展示了如何取消周期性活动的实例。

Java

// First retrieve the instances from the API.
Events instances = service.events().instances("primary", "recurringEventId").execute();

// Select the instance to cancel.
Event instance = instances.getItems().get(0);
instance.setStatus("cancelled");

Event updatedInstance = service.events().update("primary", instance.getId(), instance).execute();

// Print the updated date.
System.out.println(updatedInstance.getUpdated());

.NET

// First retrieve the instances from the API.
Events instances = service.Events.Instances("primary", "recurringEventId").Fetch();

// Select the instance to cancel.
Event instance = instances.Items[0];
instance.Status = "cancelled";

Event updatedInstance = service.Events.Update(instance, "primary", instance.Id).Fetch();

// Print the updated date.
Console.WriteLine(updatedInstance.Updated);

Python

# First retrieve the instances from the API.
instances = service.events().instances(calendarId='primary', eventId='recurringEventId').execute()

# Select the instance to cancel.
instance = instances['items'][0]
instance['status'] = 'cancelled'

updated_instance = service.events().update(calendarId='primary', eventId=instance['id'], body=instance).execute()

# Print the updated date.
print updated_instance['updated']

PHP

$events = $service->events->instances("primary", "eventId");

// Select the instance to cancel.
$instance = $events->getItems()[0];
$instance->setStatus('cancelled');

$updatedInstance = $service->events->update('primary', $instance->getId(), $instance);

// Print the updated date.
echo $updatedInstance->getUpdated();

Ruby

# First retrieve the instances from the API.
instances = client.list_event_instances('primary', 'recurringEventId')

# Select the instance to cancel.
instance = instances.items[0]
instance.status = 'cancelled'

response = client.update_event('primary', instance.id, instance)
print response.updated

修改以下所有实例

要在给定（目标）实例当天或之后更改周期性活动的所有实例，您必须发出两个单独的 API 请求。这些请求会将原始周期性活动拆分为两个活动：一个是保留未做更改的实例的原始周期性活动，一个是应用了更改的实例的新周期性活动：

调用 events.update() 以剪裁要更新的实例的原始周期性事件。为此，您可以将 RRULE 的 UNTIL 组件设置为第一个目标实例的开始时间之前。或者，您也可以设置 COUNT 组件，而不是 UNTIL。
调用 events.insert() 创建一个与原始数据完全相同的数据的新周期性事件，但您尝试进行的更改除外。新的周期性事件的开始时间必须是目标实例的开始时间。

此示例展示了如何从前面示例的周期性活动中的第三个实例将位置更改为“其他地方”。
