对于sharepoint站点，AcquireTokenSilentAsync是什么resourceid？

Question

我目前正在建立一个Office365网站，用于管理onedrive和您的sharepoint文件中的文件。目前虽然我有一个问题，如果sharepoint不是根地址一（即https://mysharepoint.sharepoint.com）但是是单独的（即https://intergendev1.sharepoint.com/anothersite或https://intergendev1.sharepoint.com/sites/moarsite）我无法获得默认情况下，令牌我无法使用Office API中的令牌获取sharepoint站点的令牌。我的理论是我使用的是不正确的ResourceId或ServiceEndpointUri，目前我只使用https://intergendev1.sharepoint.com/anothersite两者，而且我无法获取令牌，但它适用于https://intergendev1.sharepoint.com/。

提前感谢您的帮助。如果有帮助，这是我的AquireToken代码：

internal static async Task<SharepointApiClient> GetExtenalSharepoint(Uri serviceEndpointUri,
    string serviceResourceId)
{
    var signInUserId = ClaimsPrincipal.Current.FindFirst(ClaimTypes.NameIdentifier).Value;
    var userObjectId = ClaimsPrincipal.Current.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;

    AuthenticationContext authContext = new AuthenticationContext(SettingsHelper.AzureADAuthority, new AdTokenCache.AdTokenCache(signInUserId));

    try
    {
        return new SharepointApiClient(serviceEndpointUri,
            async () =>
            {
                var authResult = await authContext.AcquireTokenSilentAsync(serviceResourceId,
                    new ClientCredential(SettingsHelper.ClientId,
                        SettingsHelper.AppKey),
                    new UserIdentifier(userObjectId,
                        UserIdentifierType.UniqueId));

                return authResult.AccessToken;
            })
        {
            ResourceId = serviceResourceId
        };
    }
    catch (AdalException exception)
    {
        //Partially handle token acquisition failure here and bubble it up to the controller
        if (exception.ErrorCode == AdalError.FailedToAcquireTokenSilently)
        {
            authContext.TokenCache.Clear();
            throw exception;
        }
        return null;
    }
}
