Question

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\": \"[e-mail]\",\"inviteRedirectUrl\": \"https://MYWEBSITE.COM\"}", Encoding.UTF8, "application/json");

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

}

谢了！我可以做其他/beta命令很好。例如，获取https://graph.microsoft.com/beta/users会返回我的租户中的用户列表。

根据日志，您将收到一个401错误响应，这意味着调用方没有被授予调用API所需的权限。您需要遵循以下指南: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）。

我们还提交了一个bug来修复这个错误消息（对此很抱歉--我们确实需要在这里做得更好）。

希望这能有所帮助，
