MS Graph SDK：用戶的 SharePoint FollowedSites

Question

我正在嘗試使用 MSGraph SDK V4.54.0 獲取用戶關注的 SharePoint 站點的列表。 我發現的所有示例都使用await graphClient.Me.FollowedSites.Request().GetAsync() 。 我沒有使用Me ，而是使用特定用戶，所以我正在訪問它await graphClient.Users[userEmailAddress].FollowedSites.Request().GetAsync() 。

這是我收到的錯誤消息（我正在使用 MSTest）：

Microsoft.Graph.ServiceException: Code: generalException

讓我印象深刻的是，盡管 SDK 公開了它，但 API 中可能沒有針對 Users[x].FollowedSites 的端點。

我寫了下面的代碼，但是如您所見，它遍歷所有可能的站點，查找“用戶信息列表”，最后在用戶的項目中查找。 不用說，這是非常低效的並且需要很長時間。 大約 20 分鍾。 而且我不能 100% 確定它是否正常工作，因為它在初始請求中返回 200 個站點，這似乎有點可疑。

MSGraphClient graph = GetMSGraphClient_WithClientSecret();
SharePointClient spClient = graph.SharePoint;

var defaultField = default(KeyValuePair<string, object>);

var _sites = new List<Site>();

var sites = await graph.Client
    .Sites
    .Request()
    .GetAsync();

foreach (var site in sites)
{
    var list = (await graph.Client
        .Sites[site.Id]
        .Lists
        .Request()
        .Filter("displayName eq 'User Information List'")
        .GetAsync()).FirstOrDefault();

    if (list != null)
    {
        var items = await graph.Client
            .Sites[site.Id]
            .Lists[list.Id]
            .Items
            .Request()
            .GetAsync();

        foreach (var item in items)
        {
            var fields = await graph.Client
                .Sites[site.Id]
                .Lists[list.Id]
                .Items[item.Id]
                .Fields
                .Request()
                .GetAsync();

            var foundField = fields.AdditionalData.FirstOrDefault((_f) => _f.Key == "UserName" && _f.Value.ToString().ToLower() == graph.AuthenticationOptions.UserName.ToLower());
            if (!foundField.Equals(defaultField))
            {
                _sites.Add(site);
                break;
            }
        }
    }
}

bool actual = _sites.Count > 0;

Assert.IsTrue(actual);

有沒有更好/更有效的方法來獲取用戶關注的網站？

檢查您是否有權查看用戶關注的網站。
