C# 的圖表 API:401 - 未經授權:由於憑據無效,訪問被拒絕。 在 /planner/plans

[英]Graph API for C#: 401 - Unauthorized: Access is denied due to invalid credentials. on /planner/plans

我正在使用 Graph API。 我沒有太多這方面的經驗。 我正在創建一個應用程序以將計划添加到現有組中。

所以,我已經注冊了一個具有此權限的應用程序(您可以看到這些是委托權限):

在此處輸入圖像描述

然后,我編寫了這段代碼來使用這個端點 /planner/plans 添加一個新的 Planner(你會看到我正在使用一個令牌)。

var configAuthority = "https://login.microsoftonline.com/8318d89e-e4db-471e-85da-b34ae833813f";
            IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
                                  .Create(ConfigurationParameters.ClientID)
                                  .WithTenantId(ConfigurationParameters.TenantID)
                                  .WithClientSecret(ConfigurationParameters.ClientSecret)
                                  .WithAuthority(new Uri(configAuthority))
                                  .Build();
            ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication);
            string[] scopes = new string[] { "https://graph.microsoft.com/.default" };
            AuthenticationResult accessToken = confidentialClientApplication.AcquireTokenForClient(scopes).ExecuteAsync().Result;
            GraphServiceClient graphClient = new GraphServiceClient(authProvider);
            List<HeaderOption> requestHeaders = new List<HeaderOption>() {
                            new HeaderOption("Authorization", "Bearer " + accessToken.AccessToken)
                };
            var existingsplanners = graphClient
                                        .Groups[createPlannerForGroupRequest.GroupId.ToString()]
                                        .Planner
                                        .Plans.
                                        Request(requestHeaders)
                                        .GetAsync()
                                        .Result;
            var planner = graphClient
                        .Groups[createPlannerForGroupRequest.GroupId.ToString()]
                        .Planner
                        .Plans
                        .Request(requestHeaders)
                        .AddAsync(new PlannerPlan { 
                            Title = createPlannerForGroupRequest.Name,
                            Owner = createPlannerForGroupRequest.GroupId.ToString(),
                            ODataType = null,
                        }).Result;

兩個請求的結果是相同的。

如您所見,即使它是 Azure AD 上的委派權限,也存在權限問題。 我應該等24小時嗎? 我應該更改令牌請求者方法而不是使用 AcquireTokenForClient 嗎?

相同的方法適用於 Graph Explorer。 為現有組創建 Team 實例可以正常工作。

謝謝!

似乎您在代碼中使用了客戶端憑據授予流程,但圖表 api 僅支持委派權限。 所以我們需要使用授權碼授權流程或用戶名/密碼授權流程。 (順便說一下,我們推薦授權碼流而不是用戶名/密碼流)

有關授權代碼流程,請參閱本教程,其中包含代碼示例。

IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
    .Create(clientId)
    .WithRedirectUri(redirectUri)
    .WithClientSecret(clientSecret) // or .WithCertificate(certificate)
    .Build();

AuthorizationCodeProvider authProvider = new AuthorizationCodeProvider(confidentialClientApplication, scopes);

對於用戶名/密碼流程,您可以參考本教程以及其中的代碼示例。

IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
            .Create(clientId)
            .WithTenantId(tenantID)
            .Build();

UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, scopes);

GraphServiceClient graphClient = new GraphServiceClient(authProvider);

User me = await graphClient.Me.Request()
                .WithUsernamePassword(email, password)
                .GetAsync();

更新:

您可以按照以下步驟進行一些更改,然后您不需要在代碼中提供 client_secret 並且它也不會顯示錯誤消息The request body must contain the following parameter: 'client_assertion' or 'client_secret'

  1. Go 到您在 azure 廣告中注冊的應用程序,然后單擊“身份驗證”->“添加平台”->“移動和桌面應用程序”。 在此處輸入圖像描述

  2. 選擇第一個作為“重定向 URI”。 在此處輸入圖像描述

  3. 向下滾動並檢查此配置是否為“是”(如果“否”,請將其更改為“是”),然后單擊“保存”。 在此處輸入圖像描述

我已嘗試使用證書創建身份驗證。 首先,在應用程序注冊中應用該配置(僅具有應用程序權限)並從您之前共享的鏈接中閱讀一些指南后,我從 /Groups 獲得並且它有效。 之后,向 /Groups/{XXX-XX}/Planner/Plans 創建了一個新請求並收到權限錯誤。 創建證書的方法來自這個鏈接: https://laurakokkarinen.com/authenticating-to-office-365-apis-with-a-certificate-step-by-step/這是獲取所有組的代碼。

var url = "https://graph.microsoft.com";
var auth = new Authorization(ConfigurationParameters.TenantID, 
                            ConfigurationParameters.ClientID,
                            "‎34 64 03 a4 9c ad xx xx xx xx xx xx xx xx xx xx xx xx xx xx", 
                            @"C:\temp\Certificate.pfx", 
                            "Come up with something secure!");
var accessToken =  auth.GetAccessTokenAsync(url).Result;
using (var httpClient = new HttpClient())
{

    httpClient.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
    string urlReq = "https://graph.microsoft.com/v1.0/groups/" + createPlannerForGroupRequest.GroupId.ToString() + "";
    var response = httpClient.GetAsync(urlReq);
    Stream receiveStream = response.Result.Content.ReadAsStreamAsync().Result;
    StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
    var r = readStream.ReadToEnd();
    return r;
 }

那行得通,我可以閱讀要求的組,但是當我應用此端點時:

string urlReq = "https://graph.microsoft.com/v1.0/groups/" + createPlannerForGroupRequest.GroupId.ToString() + "/planner/plans";

我收到此錯誤消息:

    }
  }
}

我想我這次明白了:),但我得到了一個錯誤。 我現在使用這種方式來獲取令牌:

IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
            .Create(ConfigurationParameters.ClientID)
            .WithTenantId(ConfigurationParameters.TenantID)
            .Build();
            string[] scopes = new string[] { "https://graph.microsoft.com/.default" };
            UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, scopes);
            var token = authProvider.ClientApplication.AcquireTokenByUsernamePassword(scopes,u,               ToSecureString(p));
            var t = token.ExecuteAsync().Result;

沒有證書,只有用戶名和密碼。 我收到此錯誤消息:

{"error":"invalid_client","error_description":"AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'.\r\nTrace ID: d75e8aea-4d4e-4d34-a015-efd1d7f53600\r\nCorrelation ID: c3a5e38f-91e3-488c-91de-e850eef19219\r\nTimestamp: 2020-06-05 07:20:38Z","error_codes":[7000218],"timestamp":"2020-06-05 07:20:38Z","trace_id":"d75e8aea-4d4e-4d34-a015-efd1d7f53600","correlation_id":"c3a5e38f-91e3-488c-91de-e850eef19219","error_uri":"https://login.microsoftonline.com/error?code=7000218"

API 中的權限被委派給 Group.ReadAll 和 WriteAll。
