c# – 带构造函数的ServiceStack Service类

我正在使用Service Stack,但我无法(或者我不知道如何使用构造函数创建Service类).

这是我做的：

public class AppHost : AppSelfHostBase
{
    public AppHost()
        : base("ClientService", typeof(ClientService).Assembly)
    {
    }

    public override void Configure(Container container)
    {
    }
}


public class Context : ApplicationContext
{
    //This class is invoked from program.cs (winform application)
    //Here i have the logic of what form should i start.
    var listeningOn = string.Format("http://*:{0}/", port);
    var appHost = new AppHost();
    appHost.Init();
    appHost.Start(listeningOn);
    ClientService cl = new ClientService((ILayout)f, i);
}

public class ClientService : Service
{
    private readonly ILayout _activeForm;
    private static Init _initConf;


    public ClientService(ILayout f, Init i)
    {
        _activeForm = f;
        _activeForm.GetClientData(i);
        _initConf = i;
    }

    public HttpResult Post(Person request)
    {
       //Here i use _activeForm and _initConf 
    }
}

所以,正如我所说,在ClientService类中,我想创建一个构造函数,但是当我向post消息发出请求时,它会显示以下错误：

Error trying to resolve Service
‘DexBrokerClient.Services.ClientService’ or one of its auto wired
dependencies

解决方法:

ServiceStack服务是自动装配的,并使用构造函数和属性注入创建.任何Constructor参数都是必需的,必须在AppHost.Configure()中的ServiceStack的IOC中注册,例如：

public override void Configure(Container container)
{
    container.Register<ILayout>(c => ...);
    container.Register<Init>(c => ...);
}

服务上的任何公共属性都是可选的,如果存在,则将从IOC填充,否则为空.

解决服务

应使用base.ResolveService< T>解决服务.在服务类内部或者在服务外部的HostContext.ResolveService< T>()单例时的API.这将从ServiceStack的IOC中解析Service类,并使用IRequest上下文(如果有)填充.
