c# - Azure 网络作业 : C# - The Autodiscover service couldn't be located error

Question

我正在将 C# 控制台应用程序作为 Azure Webjob 上传。我得到的错误是:

Unhandled Exception:Microsoft.Exchange.WebServices.Data.AutodiscoverLocalException: TheAutodiscover service couldn't be located.

at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.InternalGetLegacyUserSettings[TSettings](StringemailAddress, List1 redirectionEmailAddresses, Int32& currentHop)

at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.GetLegacyUserSettings[TSettings](StringemailAddress)

at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.InternalGetLegacyUserSettings(StringemailAddress, List`1 requestedSettings)

at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.GetUserSettings(StringuserSmtpAddress, UserSettingName[] userSettingNames)

at Microsoft.Exchange.WebServices.Data.ExchangeService.GetAutodiscoverUrl(StringemailAddress, ExchangeVersion requestedServerVersion,AutodiscoverRedirectionUrlValidationCallbackvalidateRedirectionUrlCallback)

atMicrosoft.Exchange.WebServices.Data.ExchangeService.AutodiscoverUrl(StringemailAddress, AutodiscoverRedirectionUrlValidationCallbackvalidateRedirectionUrlCallback)

这是我的代码:

private static bool RedirectionUrlValidationCallback(string redirectionUrl)
{
    // The default for the validation callback is to reject the URL.
    bool result = false;

    Uri redirectionUri = new Uri(redirectionUrl);

    // Validate the contents of the redirection URL. In this simple validation
    // callback, the redirection URL is considered valid if it is using HTTPS
    // to encrypt the authentication credentials. 
    if (redirectionUri.Scheme == "https")
    {
        result = true;
    }
    return result;
}
static void Main(string[] args)
{
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);

    service.Credentials = new WebCredentials("email@mySite.com", "myPassword", "mysite.com");
    service.AutodiscoverUrl("email@mySite.com", RedirectionUrlValidationCallback);

    // More irrelevant code here
}

上面的代码取自这个问题作为一个已接受的答案:Connection to Office 365 by EWS API

在我的机器上作为控制台应用程序运行这段代码，运行得很好。但这作为网络作业出错了，有人可以帮忙吗？

Answer 1

我用我的 Office 365 帐户测试了您的代码，它在我这边运行良好。我还使用 Console.WriteLine 打印出返回 URL 和服务 URL。这是我在 WebJob 仪表板中看到的内容。

[05/24/2017 05:54:52 > 7adbf1: SYS INFO] Run script 'TestO365WebJob.exe' with script host - 'WindowsScriptHost'
[05/24/2017 05:54:52 > 7adbf1: SYS INFO] Status changed to Running
[05/24/2017 05:54:59 > 7adbf1: INFO] return URL: https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml
[05/24/2017 05:55:00 > 7adbf1: INFO] Service URL https://outlook.office365.com/EWS/Exchange.asmx

请仔细检查您的用户名和密码。他们是对的吗？您的密码是否已过期？

要获取失败原因的详细信息，我们可以在您的网络应用诊断日志面板上打开应用程序日志并将 TraceEnabled 属性设置为 true。我们可以通过查看应用程序跟踪日志来了解问题所在。

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.TraceEnabled = true;

此外，由于 Office365 中只有一个 EWS 端点。我们可以直接设置服务 URL 而不是使用自动发现。以下代码供您引用。

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials("user@domain.onmicrosoft.com", "password", "domain.onmicrosoft.com");
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
