c# - 使用 EWS 托管 API 验证登录凭据

Question

有没有一种方法可以在不发送电子邮件的情况下验证用户使用 EWS 托管 API 提供的登录凭据。我在 [ExchangeService] 对象上使用 AutodiscoverUrl 方法，但花费的时间太长？任何建议将不胜感激。

        try
        {
            ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
            service.Credentials = new WebCredentials("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f38b8b8b8bb38a8a8add909c9e" rel="noreferrer noopener nofollow">[email protected]</a>", "password");
            service.AutodiscoverUrl("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ed95959595ad949494c38e8280" rel="noreferrer noopener nofollow">[email protected]</a>", RedirectionUrlValidationCallback);    

            Console.WriteLine("Credentials validated successfully");
            Console.ReadLine();

        }

        catch(Exception e)
        {
            Console.WriteLine(e.Message);
            Console.ReadLine();
        }

一种加快速度的方法，虽然不太好，但很有效，就是自己设置服务 URL。 首先通过在 Debug模式下运行 autodiscoverurl 方法来获取交换服务 url:

然后，不要在服务上运行 autodiscoverurl 方法，而是添加从 autodiscoverurl 方法获取的 url:

 service.Url = new Uri("https://yourExchangeURL.com/EWS/Exchange.asmx");

您可以对邮件帐户 ( Check exchange credentials remotely and check user logged in ) 发出请求，而不是调用自动发现来验证用户凭据

var findFolderResults = service.FindFolders(WellKnownFolderName.Root, new SearchFilter.IsGreaterThan(FolderSchema.TotalCount, 0), new FolderView(10));

您的最终代码将如下所示

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bdc5c5c5c5fdc4c4c493ded2d0" rel="noreferrer noopener nofollow">[email protected]</a>", "password");
service.Url = new Uri("https://yourExchangeURL.com/EWS/Exchange.asmx");
var findFolderResults = service.FindFolders(WellKnownFolderName.Root, new SearchFilter.IsGreaterThan(FolderSchema.TotalCount, 0), new FolderView(10));
