创建组“错误请求”的Microsoft Graph Post操作

Question

我们试图向Microsoft Graph API发布一个请求，以创建一个组，如下面所述

 Microsoft.Graph.Group group = new Microsoft.Graph.Group();
                group.Description = "Self help community for library";
                group.DisplayName = "Library Assist";
                group.GroupTypes = new[] { "Unified" };
                group.MailEnabled = true;
                group.MailNickname = "library";
                group.SecurityEnabled = true;

   string json = JsonConvert.SerializeObject(group);

   var content = new StringContent(json);
   var response = httpclient.PostAsJsonAsync(Uri, content).Result;

 httpclient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "...value of baerer token...");
 httpclient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

在响应中，我们得到一个Bad request status Code400。这意味着在请求URI、头或正文中存在错误,但在Graph Explorer中,与上面相同的代码可以正常工作,我们在响应中得到结果。我在监督什么？

感谢您的任何反馈或建议。亲切的问候。

由于您已经使用microsoft.graph命名空间，因此可以使用内置的GraphServiceClient发出如下所示的请求。您不需要使用http客户端或序列化对象，这将被处理：

var graphserviceClient = new GraphServiceClient(
    new DelegateAuthenticationProvider(
        (requestMessage) =>
        {
            requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", "<your-access-token>");              
        }));

var group = new Microsoft.Graph.Group
{
    DisplayName = "Library Assist",
    Description = "Self help community for library",
    MailNickname = "library",
    MailEnabled = true,
    SecurityEnabled = true,
    GroupTypes = new List<string> { "Unified" }
};      

var createdGroup = await graphserviceClient.Groups.Request().AddAsync(group);
