如何使用服务帐户正确获取用户的日历事件？

Question

我正在尝试为域中的用户检索日历事件.我有服务帐户访问权限,但在尝试获取特定用户事件时出现404错误.继承人连接代码:

NetHttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
    GoogleCredential credential = new GoogleCredential.Builder()
            .setTransport(httpTransport)
            .setJsonFactory(JSON_FACTORY)
            .setServiceAccountId(googleApiServiceAccountId)
            .setServiceAccountScopes(Collections.singleton(CalendarScopes.CALENDAR_READONLY))
            .setServiceAccountPrivateKey(SecurityUtils.loadPrivateKeyFromKeyStore(
                    SecurityUtils.getPkcs12KeyStore(),
                    getClass().getClassLoader().getResourceAsStream(googleApiPrivateKeyPath),
                    NOTASECRET, PRIVATEKEY, NOTASECRET))
            .build();

    calendarApi = new Calendar.Builder(httpTransport,
            JSON_FACTORY, credential).setApplicationName(getApplicactionName()).build();

活动列表方法:

public List<Event> getCalendarEventsForUserAndDates(String userEmail, Long dateFrom, Long dateTo) {
    try {
        String pageToken = null;
        List<Event> allEvents = Lists.newArrayList();
        do {
            ArrayMap<String, Object> parameters = new ArrayMap<String, Object>();
            parameters.add("xoauth_requestor_id", userEmail);
            Calendar.Events.List list = calendarApiBean.getCalendarApi()
                    .events().list("primary");
            list.setTimeMax(new DateTime(dateFrom, 0))
                    .setTimeMin(new DateTime(dateTo, 0))
                    .setUnknownKeys(parameters);
            Events events = list.setPageToken(pageToken)
                    .execute();
            List<? extends Event> items = events.getItems();
            if (items != null) {
                allEvents.addAll(items);
            }
            pageToken = events.getNextPageToken();
        } while (pageToken != null);
        return allEvents;
    } catch (IOException e) {
        logger.error("error while retriving calendar events for {} and dates {} {} ", userEmail, dateFrom, dateTo);
        logger.error("exception", e);
        return Collections.emptyList();
    }

}

当我尝试将xoauth_requestor_id设置为用户的电子邮件并列出"primary"时,我会收到服务帐户的日历事件.当我将events().list()参数更改为用户的电子邮件时,我收到以下错误:

com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found
{
  "code" : 404,
  "errors" : [ {
    "domain" : "global",
    "message" : "Not Found",
    "reason" : "notFound"
  } ],
  "message" : "Not Found"
}

谢谢你的帮助.

为了解决这个问题，我必须将此服务帐户添加到域管理上的授权 API 客户端。客户端名称是服务帐户客户端 ID，范围是只读日历
