未知错误调用 /beta/invitations

Question

我一定是遗漏了一些明显的东西。发布到测试版 API https://graph.microsoft.com/beta/invitations (api ref: https://graph.microsoft.io/en-us/docs/api-reference/beta/api/invitation_post) 时，我得到

{ "error": { "code": "UnknownError", "message": "", "innerError": { "request-id": "e41b0eab-c39c-4cf8-9034-341c81fc722c", "date": "2017-01-14T19:26:55" } } }

这是我的代码：

namespace ConsoleApplication1
{
    public class Program
    {
        static void Main(string[] args)
        {
            GraphClient g = new GraphClient();
            Console.WriteLine(g.SendPost(g.authContext, g.credential).Result);
        }        
    }

    public class GraphClient
    {
        public AuthenticationContext authContext;
        public ClientCredential credential;
        public GraphClient()
        {
            this.authContext = new AuthenticationContext("https://login.microsoftonline.com/MYTENANT.onmicrosoft.com");
            this.credential = new ClientCredential("MYCLIENTID", "MYCLIENTSECRET");
        }
        public async Task<string> SendPost(AuthenticationContext authContext, ClientCredential credential)
        {
            AuthenticationResult result = await authContext.AcquireTokenAsync("https://graph.microsoft.com", credential);

            HttpClient http = new HttpClient();
            HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "https://graph.microsoft.com/beta/invitations");
            request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
            request.Content = new StringContent("{\"invitedUserEmailAddress\": \"MYEMAIL@MYDOMAIN.COM\",\"inviteRedirectUrl\": \"https://MYWEBSITE.COM\"}", Encoding.UTF8, "application/json");

            HttpResponseMessage response = await http.SendAsync(request);
            return await response.Content.ReadAsStringAsync();
        }
    }

}

谢谢！我可以很好地执行其他 /beta 命令。例如，按预期在我的租户中获取 https://graph.microsoft.com/beta/users returns 用户列表。

根据日志，您收到了 401 错误响应，这意味着调用者未被授予调用 API 所需的权限。您需要遵循此处的指导：https://graph.microsoft.io/en-us/docs/api-reference/beta/api/invitation_post，这表明您需要 Directory.ReadWrite.All 或 User.ReadWrite.All（尽管我不确定后者是否有效或现在是否可用）。

我们还提交了一个错误来修复此错误消息（对此感到抱歉 - 我们确实需要在这方面做得更好）。

希望对您有所帮助，
