【问题描述】：

我正在关注以下教程（Outlook dev center tutorial），我的代码在这部分（在获取令牌时）抛出了一个unknown_error：

    public async Task<ActionResult> Authorize() {
        // Get the 'code' parameter from the Azure redirect
        string authCode = Request.Params["code"];

        string authority = "https://login.microsoftonline.com/common";
        string clientId = System.Configuration.ConfigurationManager.AppSettings["ida:ClientID"]; ;
        string clientSecret = System.Configuration.ConfigurationManager.AppSettings["ida:ClientSecret"]; ;
        AuthenticationContext authContext = new AuthenticationContext(authority);

        // The same url we specified in the auth code request
        Uri redirectUri = new Uri(Url.Action("Authorize", "Home", null, Request.Url.Scheme));

        // Use client ID and secret to establish app identity
        ClientCredential credential = new ClientCredential(clientId, clientSecret);

        try {
            // Get the token
            var authResult = await authContext.AcquireTokenByAuthorizationCodeAsync(authCode, redirectUri, credential, scopes); <--- HERE

            // Save the token in the session
            Session["access_token"] = authResult.Token;

            // Try to get user info
            Session["user_email"] = GetUserEmail(authContext, clientId);

            return Redirect(Url.Action("Inbox", "Home", null, Request.Url.Scheme));
        } catch (AdalException ex) {
            return Content(string.Format("ERROR retrieving token: {0}", ex.Message));
        }
    }

堆栈跟踪：

有人知道可能出了什么问题吗？

【问题讨论】：

您使用的是什么版本的 ADAL 库？您可以在 Visual Studio 的包管理器控制台中运行 get-package Microsoft.Experimental.IdentityModel.Clients.ActiveDirectory 以获取版本。
@JasonJohnston：版本是：4.0.208052020-alpha
好的，我使用的是同一个版本，没有问题。 catch (AdalException ex) 行是否捕获了此错误？那里有更多信息吗？
@JasonJohnston 错误确实被 AdalException 捕获，没有其他信息可用：/

【解决方案1】：

你可以试试这个项目，它已经实现了来自你的引用 url 的代码。并且可以成功登录。

https://github.com/aukgit/Google-Outlook-Calender-Integrate/releases

可能有几件事可能出错：

可能您错过了下载确切的 nuget 包

安装包 Microsoft.Experimental.IdentityModel.Clients.ActiveDirectory -Version 4.0.208020147-alpha -Pre

安装包 Microsoft.Office365.OutlookServices-V2.0

可能应用程序未正确注册到 url。
可能没有给出范围，
