使用 Graph API，使用 http post 请求在 Azure Active Directory (B2C) 中创建新用户

我之前一直使用 Active Directory 身份验证库 (ADAL) 以编程方式添加用户，但现在我需要定义“signInNames”（= 用户电子邮件），而 ADAL 似乎无法实现这一点（如果我错了，请告诉我） 。

现在我尝试使用 HTTP POST 以编程方式添加新用户（本地帐户），如下MSDN 上的文档.

//Get access token (using ADAL)
var authenticationContext = new AuthenticationContext(AuthString, false);
var clientCred = new ClientCredential(ClientId, ClientSecret);
var authenticationResult = authenticationContext.AcquireTokenAsync(ResourceUrl, clientCred);
var token = authenticationResult.Result.AccessToken;


//HTTP POST CODE
const string mail = "[email protected]";
// Create a new user object.
var user = new CustomUser
{
    accountEnabled = true,
    country = "MS",
    creationType = "LocalAccount",
    displayName = mail,
    passwordPolicies = "DisablePasswordExpiration,DisableStrongPassword",
    passwordProfile = new passwordProfile { password = "jVPmEm)6Bh", forceChangePasswordNextLogin = true },
    signInNames = new signInNames { type = "emailAddress", value = mail }
};

var url = "https://graph.windows.net/" + TenantId + "/users?api-version=1.6";

var jsonObject = JsonConvert.SerializeObject(user);

using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

    var response = client.PostAsync(url,
        new StringContent(JsonConvert.SerializeObject(user).ToString(),
            Encoding.UTF8, "application/json"))
            .Result;

    if (response.IsSuccessStatusCode)
    {
        dynamic content = JsonConvert.DeserializeObject(
            response.Content.ReadAsStringAsync()
            .Result);

        // Access variables from the returned JSON object
        var appHref = content.links.applications.href;
    }
}

但我没有成功，得到这样的回应：

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content:....}

有什么想法我应该做什么吗？我成功使用 Powershell 脚本，但我需要在我的 C# 应用程序中执行此操作。

感谢您的回复 飞雪，我相信我有正确的权限。我做了什么来解决我的问题。

首先，我删除了自己的自定义类“NewUser”，然后我下载了这个示例项目：https://github.com/AzureADQuickStarts/B2C-GraphAPI-DotNet/blob/master/B2CGraphClient/B2CGraphClient.cs消除我的代码错误的风险。我修改了它来支持我的需求，然后创建了一个简单的 JObject：

var jsonObject = new JObject
                        {
                            {"accountEnabled", true},
                            {"country", customer.CustomerBase.Company},
                            {"creationType", "LocalAccount"},
                            {"displayName", pendingCustomer.Email.Trim()},
                            {"passwordPolicies", "DisablePasswordExpiration,DisableStrongPassword"},
                            {"passwordProfile", new JObject
                            {
                                {"password", pwd},
                                {"forceChangePasswordNextLogin", true}
                            } },
                            {"signInNames", new JArray
                                {
                                    new JObject
                                    {
                                        {"value", pendingCustomer.Email.Trim()},
                                        {"type", "emailAddress"}
                                    }
                                }
                            }
                        };

client = new B2CGraphClient(ClientId, ClientSecret, TenantId);
var response = await client.CreateUser(jsonObject.ToString());
var newUser = JsonConvert.DeserializeObject<User>(response);

来自 B2CGraphClient.cs

        private async Task<string> SendGraphPostRequest(string api, string json)
    {
        // NOTE: This client uses ADAL v2, not ADAL v4
        var result = authContext.AcquireToken(Globals.aadGraphResourceId, credential);
        var http = new HttpClient();
        var url = Globals.aadGraphEndpoint + tenant + api + "?" + Globals.aadGraphVersion;

        var request = new HttpRequestMessage(HttpMethod.Post, url);
        request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
        request.Content = new StringContent(json, Encoding.UTF8, "application/json");
        var response = await http.SendAsync(request);

        if (!response.IsSuccessStatusCode)
        {
            var error = await response.Content.ReadAsStringAsync();
            var formatted = JsonConvert.DeserializeObject(error);
            //Console.WriteLine("Error Calling the Graph API: \n" + JsonConvert.SerializeObject(formatted, Formatting.Indented));
            Logger.Error("Error Calling the Graph API: \n" + JsonConvert.SerializeObject(formatted, Formatting.Indented));
        }
        Logger.Info((int)response.StatusCode + ": " + response.ReasonPhrase);

        return await response.Content.ReadAsStringAsync();
    }

这最终解决了我所有的问题，这可能是我的 NewCustomer 类序列化中的格式错误，然后被 API 拒绝。
