以编程方式创建的 Web 服务在客户端服务调用时失败

Question

我创建了一个控制台应用程序项目来以编程方式托管 Web 服务，但是当我尝试为我的 Web 服务创建客户端代理并在其上调用方法时，出现以下错误：

An error occurred while making the HTTP request to https://localhost:8000/FileRetrievalPoC. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

其内部异常：

The underlying connection was closed: An unexpected error occurred on a send.

其内部异常：

Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

其内部异常：

An existing connection was forcibly closed by the remote host

Program.cs:

class Program
{
    static void Main(string[] args)
    {
        var address = "https://localhost:8000/FileRetrievalPoC";
        Console.WriteLine("Starting a service at {0}...", address);
        FileRetrievalService.Start(address, StoreLocation.LocalMachine, StoreName.My, "localhost");
        Console.WriteLine("Service started.");
        Console.WriteLine("Press Enter to create a new proxy client and call the Get method.");
        Console.WriteLine("Press Escape to end the application.");
        while (true)
        {
            var key = Console.ReadKey();
            if (key.Key == ConsoleKey.Enter)
            {
                var proxy = FileRetrievalService.Connect(address, "localhost", "exampleUsername", "examplePassword", StoreLocation.LocalMachine, StoreName.My, "localhost");
                proxy.Get(@"C:\Users\User\Desktop\Document.txt");
                ((IClientChannel)proxy).Close();
            }
            else if (key.Key == ConsoleKey.Escape)
                break;
        }
        FileRetrievalService.Stop();
    }
}

IFileRetrieval.cs:

[ServiceContract]
public interface IFileRetrieval
{
    [OperationContract]
    string Get(string path);
    [OperationContract]
    void Set(string path, string contents);
}

FileRetrievalService.cs:

class FileRetrievalService : IFileRetrieval
{

    private static BasicHttpsBinding _binding = new BasicHttpsBinding()
    {
        Name = "FileRetrievalPoC",
        HostNameComparisonMode = HostNameComparisonMode.Exact,
        Security = new BasicHttpsSecurity()
        {
            Message = new BasicHttpMessageSecurity()
            {
                AlgorithmSuite = SecurityAlgorithmSuite.Basic256Sha256Rsa15,
                ClientCredentialType = BasicHttpMessageCredentialType.UserName
            },
            Mode = BasicHttpsSecurityMode.TransportWithMessageCredential,
            Transport = new HttpTransportSecurity()
            {
                ClientCredentialType = HttpClientCredentialType.Windows
            }
        },
        SendTimeout = TimeSpan.FromMinutes(1),
        CloseTimeout = TimeSpan.FromMinutes(1),
        OpenTimeout = TimeSpan.FromMinutes(1),
        ReceiveTimeout = TimeSpan.FromMinutes(1)
    };
    private static ChannelFactory<IFileRetrieval> _channelFactory;
    private static ServiceHost _host;

    public static void Start(string address, StoreLocation location, StoreName name, string subject)
    {
        _host = new ServiceHost(typeof(FileRetrievalService));
        _host.Credentials.ServiceCertificate.SetCertificate(location, name, X509FindType.FindBySubjectName, subject);
        _host.AddServiceEndpoint(typeof(IFileRetrieval), _binding, address);
        _host.Open();
    }

    public static void Stop()
    {
        if (_host != null)
            _host.Close();
        if (_channelFactory != null)
            _channelFactory.Close();
    }

    public static IFileRetrieval Connect(string address, string domain, string username, string password, StoreLocation location, StoreName name, string subject)
    {
        if (_channelFactory == null)
            _channelFactory = new ChannelFactory<IFileRetrieval>(_binding, address);
        _channelFactory.Credentials.ClientCertificate.SetCertificate(location, name, X509FindType.FindBySubjectName, subject);
        _channelFactory.Credentials.UserName.UserName = username;
        _channelFactory.Credentials.UserName.Password = password;
        _channelFactory.Credentials.Windows.ClientCredential = new NetworkCredential(username, password, domain);
        return _channelFactory.CreateChannel();
    }

    public string Get(string path)
    {
        throw new NotImplementedException();
    }

    public void Set(string path, string contents)
    {
        throw new NotImplementedException();
    }
}

这一切都是以编程方式完成的，我查看了 Stack Overflow 但找不到发生这种情况的充分理由。有谁知道问题出在哪里？您可以将此源代码添加到一个新的控制台应用程序中，然后运行它在您的本地计算机上进行尝试，并亲眼见证它的发生。它是SSL证书吗？如果是这样，我怎样才能因为这里的错误原因而变得更加冗长？这不是一个很有帮助的例外。

编辑：我想我可能在这里漏掉了一步，such as using netsh to bind a certificate to my machine's port。

Answer 1

我的问题是 I did not use netsh to bind the certificate to my machine's port。打开管理命令提示符并调用：

netsh http add sslcert ipport=0.0.0.0:8000 appid=<A randomly generated GUID for your application> certhash=<Your localhost certificate's thumbprint from the default MY store, which is under Local Machine -> Personal, which you can get from the MMC Certificates snap-in>

下一步是确保它在客户端受信任的人之下。至少，对我来说是这样，因为我使用的是我为 localhost 测试目的生成的自签名证书。因此，例如，如果您从 Comodo 或 Verisign 或其他一些 CA 获得证书，您的证书可能根本不需要这个，因为根 CA 将被信任，通常默认情况下 Windows，因为根 CA public 这些证书开箱即用，位于证书 MMC 管理单元的受信任的根证书颁发机构部分。

然后，您需要做的就是确保您的计算机凭据正确无误。我正在使用 Windows 身份验证，因此它会尝试断言我的凭据有效（这些在我调用 Connect 方法的代码中指定）。

随着年龄的增长，我发现我越来越倾向于自己回答问题...

编辑：您只需使用 Trusted People 商店即可完成所有这些操作。如果你确实想这样做，那么在我上面的代码中使用 StoreName.TrustedPeople，在你的 netsh 命令中，指定 certstorename=TrustedPeople，否则它默认为 MY，这是 Personal 存储在证书 MMC 管理单元中。

此外，要删除已绑定的 SSL 证书，请使用 netsh http delete sslcert ipport=0.0.0.0:8000

此外，我的代码不需要设置客户端证书即可运行，因此可以从 Connect 方法中删除。如果你们中的任何人计划在生产中使用它，还需要进一步加强。
