Google Calendar API eventResponse.getHtmlLink() -如何获取允许“添加视频通话”的事件url

// 创建Google Calendar服务对象
Calendar service = new Calendar.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials(HTTP_TRANSPORT))
        .setApplicationName(APPLICATION_NAME)
        .build();

// 获取事件的响应对象
Event event = service.events().get(calendarId, eventId).execute();
EventAttendeeResponse response = event.getAttendees().get(0).getResponseStatus();

// 获取允许"添加视频通话"的事件URL
String htmlLink = event.getHangoutLink();

// 打印事件URL
System.out.println("事件URL：" + htmlLink);
