如何使用服务帐户正确获取用户的日历事件? [英] How to correctly obtain user's Calendar events using service account?

问题描述

我正在尝试为域中的用户检索日历事件.我具有服务帐户访问权限，但是当我尝试获取特定的用户事件时出现404错误. 继承人的连接代码:

I'm trying to retrive Calendar events for a user in a domain. I have service account access, but i get 404 error when I try to get specific user events. Heres connection code:

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();

事件列表方法:

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主要"时，我会获得我的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，出现以下错误:

When i try to set xoauth_requestor_id to user's email and list 'primary', i get Calendar events for my Service Accounts. When I change events().list() parameter to user's email I get an following Error:

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

感谢您的帮助.

推荐答案

要解决此问题，我必须将此服务帐户添加到Domain Administration上的授权API客户端. 客户名称为服务帐户客户ID"，范围为只读日历"

To solved this problem I had to add this service account to authorized API clients on Domain Administration. Client name is Service Account Client ID and scope was for Readonly Calendar
