Microsoft Graph SDK-登录 [英] Microsoft Graph SDK - Login

问题描述

使用MS Graph只能登录一次吗?当前，每当我调用graphServiceClient时，它将要求我登录或选择已登录的用户.有什么办法可以避免选择登录用户的过程?预先感谢.

Is it possible to only log in once using MS Graph? Currently whenever I call the graphServiceClient it will ask me to sign in or to choose the signed in user. Is there any way that the process of choosing the signed in user can be avoided? Thanks in advance.

当前，这就是我初始化graphService的方式.

Currently this is how I initialize the graphService.

    public static GraphServiceClient GetAuthenticatedClient()
    {
        GraphServiceClient graphClient = new GraphServiceClient(
            new DelegateAuthenticationProvider(
                async (requestMessage) =>
                {
                    string appID = ConfigurationManager.AppSettings["ida:AppId"];

                    PublicClientApplication PublicClientApp = new PublicClientApplication(appID);
                    string[] _scopes = new string[] { "Calendars.read", "Calendars.readwrite" };

                    AuthenticationResult authResult = null;
                    authResult = await PublicClientApp.AcquireTokenAsync(_scopes); //Opens Microsoft Login Screen    

                    // Append the access token to the request.
                    requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", authResult.AccessToken);
                }));
        return graphClient;
    }

现在，每当我使用标准SDK功能时，它都会要求我登录:

等待graphClient.Me.Events [testID] .Request().UpdateAsync(x);

然后当我使用其他功能时，它将再次询问我:

等待graphClient.Me.Events.Request().AddAsync(newEvent);

推荐答案

是可以的. AcquireTokenAsync始终会触发登录.相反，您需要实现令牌缓存并使用AcquireTokenSilentAsync. https://docs.microsoft.com/zh-cn/outlook/rest/dotnet-tutorial 有一个网络应用程序示例.

Yes it is possible. AcquireTokenAsync does always trigger logon. Instead, you need to implement a token cache and use AcquireTokenSilentAsync. https://docs.microsoft.com/en-us/outlook/rest/dotnet-tutorial has a web app example.
