为什么在使用ServiceStack客户端时从ServiceStack服务获得401响应

我已经开发了一套ServiceStack Web服务，这些服务已经运行了好几个月了，主要是从使用ServiceStack客户端库的WPF应用程序开发的。

由于与其他开发人员的服务产生了一些其他问题，因此我决定查看现有WPF应用程序与使用Fiddler的服务之间的请求和响应。

我注意到，在对Web服务方法的每个请求中，ith显示两个请求，第一个返回响应401，第二个返回200。

我们所有的Web服务方法都设置为使用“任何”功能，允许来自客户端的任何动词-即-

[Authenticate]
public object Any(DriverQuery request)
{
    var driver = DriverRepository.GetDriver<DriverEntity>(request.DriverUserId);
    return new DriverResponse { Driver = driver };
}

客户端只使用JsonServiceClient.Send方法-即

var response = client.Send(new DriverQuery { DriverUserId = driverUserId });

我们正在使用基本身份验证。

我担心为什么会发生这种情况，如果这是正常现象还是不正常现象，如果不是，我在做什么错呢？

根据要求提供其他信息

返回401响应的请求：-

我创建了一个从ServiceStack JsvServiceClient派生的基类，该基类处理提供身份验证信息。如下所示。

public abstract class BaseServiceClient : JsvServiceClient
{
    protected BaseServiceClient(string baseUri, TimeSpan serviceTimeout, string currentUserName)
        : base(baseUri)
    {
        Headers.Add(CustomHeaders.LoggedOnUserNameHeader, currentUserName);
        UserName = WebServiceSecurity.GetMasterUsername();
        Password = WebServiceSecurity.GetMasterPassword();
        Timeout = serviceTimeout;
    }
}

服务认证配置代码

Plugins.Add(new AuthFeature(() => new AuthUserSession(), new IAuthProvider[] {new BasicAuthProvider()}));
    var userRepository = new InMemoryAuthRepository();
    container.Register<IUserAuthRepository>(userRepository);

    string hash;
    string salt;

    new SaltedHash().GetHashAndSaltString(WebServiceSecurity.GetMasterPassword(), out hash, out salt);
userRepository.CreateUserAuth(new UserAuth
{
    Id = 1,
    UserName = *UserName*,
    PasswordHash = ******,
    Salt = ******,
    Roles = new List<string> { *Role* },
}, *Password*);

重要的是要注意，我们仅对Web服务方法进行一次调用，并且这两个请求均作为此单个调用的一部分而产生

如果有人可以帮助或确认这是正常行为，将不胜感激。

提前谢谢了
