创建运行空间时发生内部错误

Question

我有一个应用程序，允许用户通过一个简单的 Web 界面在 Exchange 上更新其他用户的外出消息。

我最初尝试使用 Microsoft.Exchange.WebServices 连接到 Exchange 服务来创建它，但由于系统帐户所需的权限（帐户更新通过 EWS 的 OOF 消息需要 FULL 邮箱权限）。

所以为了克服这个问题，我创建了以下 class，它使用 PowerShell 远程处理来实现同样的事情：

public class ExchangeShell
{
    private Runspace MyRunSpace;
    private PowerShell MyPowerShell;
    private Uri ExchangeServer;

    public ExchangeShell()
    {
        var exchangeserverurl = new Uri("http://EXCHANGESERVER/PowerShell");
        var psCredential = GetCredentials();
        var connectionInfo = new WSManConnectionInfo(exchangeserverurl, "http://schemas.microsoft.com/powershell/Microsoft.Exchange", psCredential);

        try
        {
            MyRunSpace = RunspaceFactory.CreateRunspace(connectionInfo);
        }
        catch (Exception ex)
        {
            Email.Send($"Unable to connect \n\n Error: {ex.Message} ");
            Environment.Exit(Environment.ExitCode);
        }
    }

    public OofSettings GetOofSettings(string email)
    {
        using (MyRunSpace)
        {
            MyRunSpace.Open();

            using (var powerShell = PowerShell.Create())
            {
                powerShell.Runspace = MyRunSpace;

                var command = new PSCommand();

                command.AddCommand("Get-MailboxAutoReplyConfiguration");
                command.AddParameter("Identity", email);

                powerShell.Commands = command;

                var result = powerShell.Invoke();

                var oofSetting = new OofSettings();

                oofSetting.State = (OofState)Enum.Parse(typeof(OofState), result[0].Properties["AutoReplyState"].Value.ToString());
                oofSetting.Duration = new TimeWindow((DateTime)result[0].Properties["StartTime"].Value, (DateTime)result[0].Properties["EndTime"].Value);
                oofSetting.ExternalAudience = (OofExternalAudience)Enum.Parse(typeof(OofExternalAudience), result[0].Properties["ExternalAudience"].Value.ToString());
                oofSetting.InternalReply = result[0].Properties["InternalMessage"].Value.ToString();
                oofSetting.ExternalReply = result[0].Properties["ExternalMessage"].Value.ToString();

                return oofSetting;
            }
        }
    }

    private PSCredential GetCredentials()
    {
        var secureString = new SecureString();
        foreach (char c in @"PASSWORD")
        {
            secureString.AppendChar(c);
        }
        return new PSCredential("SERVICEACCOUNT", secureString);
    }
}

这也适用于运行在我的本地机器上或作为服务器上的 EXE。

但是，当我通过 IIS 托管它时，我在这一行看到错误：

MyRunSpace = RunspaceFactory.CreateRunspace(connectionInfo);

An internal error occurred.

这不是一条非常有用的错误消息，我不确定如何调试它。有人对此有什么建议吗？

更新

我在 web.config 中附加了一个跟踪器，这里是选择用户以检索其外出详细信息后的一些跟踪信息：

Category      Message                  From First(s)     From Last(s)
aspx.page     Begin PreInit   
aspx.page     End PreInit              0.000025          0.000025 
aspx.page     Begin Init               0.000035          0.000009 
aspx.page     End Init                 0.000057          0.000022 
aspx.page     Begin InitComplete       0.000065          0.000008 
aspx.page     End InitComplete         0.000073          0.000008 
aspx.page     Begin PreLoad            0.000081          0.000008 
aspx.page     End PreLoad              0.000093          0.000012 
aspx.page     Begin Load               0.000101          0.000008

但我真的不知道如何使用这些信息 - 它似乎并没有透露太多关于 runspace 和服务器之间实际发生的事情..

堆栈跟踪：

Answer 1

如果您想进行调试，您应该能够在 .NET 中使用跟踪或仅附加调试器

一个常见的问题是证书检查失败，因此您可能想尝试绕过那些，例如

connectionInfo.SkipCACheck = 真； connectionInfo.SkipCNCheck = 真； connectionInfo.MaximumConnectionRedirectionCount = 4;

Answer 2

造成此问题的原因是我在服务器上安装了错误版本的 PowerShell。

遗憾的是 Internal Error 消息没有提到这一点，但可能是一个很好的消息来检查何时发生此错误。
