[英]Graph API - Authentication Token and Task Cancellation Error

問題描述

We have an application "App1" in Azure will all the required permissions and have 7 instances of a Windows service in C# that uses the same Azure Application "App1" to connect to Outlook Mailboxes. 所有 7 個 windows 服務實例的代碼都是相同的，但配置不同，即每個實例都連接到一個唯一的郵箱。

問題：

我們使用下面的代碼進行身份驗證，並且每個服務都在其自己的服務器（Windows）上運行，當執行此身份驗證代碼時，假設所有服務都會出現令牌重疊問題，因為它使用相同的 Azure“App1”或因為它為每個服務實例連接到一個唯一的郵箱，所以它不會成為問題，並且每個服務實例都有唯一的訪問令牌。

AuthenticationResult authResult = null;
        GraphServiceClient graphClient = null;
        IMailFolderMessagesCollectionPage inboxMessage = null;
        try
        {

            string tenantId = "TenantId";
            string clientId = "ClientId";
            string clientSecret = "ClientSecret";
            var authority = $"https://login.microsoftonline.com/{tenantId}";
            var app = ConfidentialClientApplicationBuilder
                .Create(clientId)
                .WithClientSecret(clientSecret)
                .WithAuthority(new Uri(authority))
                .Build();
            var scopes = new[] { "https://graph.microsoft.com/.default" };
            authResult = await app.AcquireTokenForClient(scopes).ExecuteAsync();

        }
        catch (Exception ex)
        {
           //return;
        }

        if (authResult != null)
        {
            graphClient = new GraphServiceClient(
            new DelegateAuthenticationProvider(requestMessage =>
            {
                requestMessage.Headers.Authorization =
                    new AuthenticationHeaderValue("bearer", authResult.AccessToken);

                return Task.FromResult(0);
            }));

我們經常遇到錯誤，想知道這個設置是否會影響我們的應用程序。 如果不是，我們收到此類錯誤的原因是什么。

基本上，當我們使用客戶端憑據流生成訪問令牌並使用它來調用圖 api 時，假設您的“App1”有很多應用程序 api 權限，例如User.ReadWrite.All,Mail.ReadBasic.All,Files.ReadWrite.All ，然后令牌將包含所有這些 api 權限，以便它可以用於搜索用戶/郵件/文件。 如您所見，這個令牌將包含如此大的權限。

然后 go 回到您的場景，您無需擔心token overlapping ，因為令牌僅代表authorization ，因為它包含正確的 api 權限，那么您的每個應用程序生成的令牌都可以在其他應用程序中使用，因為它們都有相同的配置。 換句話說，它們都是有效的。

關於您的異常，我不確定哪一行報告了它，您可以嘗試調試代碼以找到有問題的代碼。 恐怕它可能與return Task.FromResult(0); . 我搜索了錯誤消息，這里有一個問題遇到了同樣的錯誤。 無論如何，這似乎是一個意想不到的任務問題。

由於您現在使用的是圖形客戶端，因此您無需先獲取訪問令牌，就可以直接調用圖形 api。 像下面的代碼：

var scopes = new[] { "https://graph.microsoft.com/.default" };
string tenantId = "TenantId";
string clientId = "ClientId";
string clientSecret = "ClientSecret";
var clientSecretCredential = new ClientSecretCredential(
                tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
var user = await graphClient.Users.Request().GetAsync();
