在给定权限并且accessToken使用Microsoft Graph API获得的情况下，请求获取日历事件响应404

Question

我想构建一个Web应用程序，它具有获取其他人的日历事件的功能。我已在https://apps.dev.microsoft.com/注册该应用并请求Calendars.Read权限。我确信管理员已同意分配这些权限（我允许他通过adminconsent页面执行此操作）。

下面是我的ASP.Net控制器代码，旨在测试Events API。目标API是：

MicrosoftGraphCalendarApi = "https://graph.microsoft.com/v1.0/users/{0}/events";

public async Task<string> GetUserCalendar()
{
    ConfidentialClientApplication cc =
        new ConfidentialClientApplication(Globals.ClientId, Globals.RedirectUri,
            new ClientCredential(Globals.ClientSecret),
            null,
            new TokenCache());

    AuthenticationResult result =
        await cc.AcquireTokenForClientAsync(new string[] { "https://graph.microsoft.com/.default" });

    HttpClient client = new HttpClient();
    string requestUrl = String.Format(Globals.MicrosoftGraphCalendarApi, "lizhuowei@intl.zju.edu.cn");

    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, requestUrl);
    request.Headers.Authorization =
        new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", result.AccessToken);

    HttpResponseMessage response = await client.SendAsync(request);
    response.EnsureSuccessStatusCode();

    string json = await response.Content.ReadAsStringAsync();
    return json;
}

调用时，似乎我设法得到了accessToken。但是，获取events的请求会回复404错误。以下是完整的回复：

    StatusCode : 404,
    ReasonPhrase: 'Not Found',

        }

      Content-Type: application/json
    }
}
System.Net.Http.HttpResponseMessage

我不知道问题可能在哪里。请帮助，谢谢。

终于解决了。用户必须分享＆＃39;或者＆＃39;发布＆＃39;首先是目标日历。否则，即使得到管理员的同意，其他帐户也无法访问它。
