Question

我尝试按照此this教程中的步骤通过oAuth对我的应用进行身份验证，并将检索到的令牌用于EWS托管API。

以下是最终代码：

static void Run()
        {
            string authority = ConfigurationSettings.AppSettings["authority"];
            string clientID = ConfigurationSettings.AppSettings["clientID"];
            Uri clientAppUri = new Uri(ConfigurationSettings.AppSettings["clientAppUri"]);
            string serverName = ConfigurationSettings.AppSettings["serverName"];

            AuthenticationResult authenticationResult = null;
            AuthenticationContext authenticationContext = new AuthenticationContext(authority, false);


            string errorMessage = null;
            try
            {
                Console.WriteLine("Trying to acquire token");
                authenticationResult = authenticationContext.AcquireToken(serverName, clientID, clientAppUri, PromptBehavior.Auto);
            }
            catch (AdalException ex)
            {
                errorMessage = ex.Message;
                if (ex.InnerException != null)
                {
                    errorMessage += "\nInnerException : " + ex.InnerException.Message;
                }
            }
            catch (ArgumentException ex)
            {
                errorMessage = ex.Message;
            }

            if (!string.IsNullOrEmpty(errorMessage))
            {
                Console.WriteLine("Failed: {0}" + errorMessage);
                return;
            }

            Console.WriteLine("\nMaking the protocol call\n");
            ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2013);
            exchangeService.Url = new Uri(serverName + "ews/exchange.asmx");
            exchangeService.TraceEnabled = true;
            exchangeService.TraceFlags = TraceFlags.All;
            exchangeService.Credentials = new OAuthCredentials(authenticationResult.AccessToken);
            //exchangeService.TraceListener = new TraceListener();
            var res = exchangeService.FindFolders(WellKnownFolderName.Root, new FolderView(10));
        }

这是配置文件：

    <add key="authority" value="https://login.windows.net/???.onmicrosoft.com" />
    <add key="clientId" value="???" />
    <add key="clientAppUri" value="https://localhost/8a4abb13c70dab64a18ae81089bc2cff"/>
    <add key="serverName" value="https://outlook.office365.com/" />

以下是错误消息：

The request failed. The remote server returned an error: (401) Unauthorized.

这里是ExchangeService的跟踪：

Answer 1

您的令牌中有太多的范围（即scp声明）。该值应仅为full_access_as_user。在Azure管理门户中，您应该拥有的唯一Office 365 Exchange Online权限是通过Exchange Web服务＆＃34;访问邮箱作为登录用户。

使用OAuth
