我正在使用服務堆棧創建自託管REST服務& AppHostHttpListenerBase。我想用我的服務基本URI（例如「API」），像這樣：配置ServiceStack基本URI
http://myserver/api/service1/param
http://myserver/api/service2/param
如何做到這一點無需在每個我的路線定義「API」。在IIS中，我可以設置一個虛擬目錄來隔離服務，但如何在自託管時執行此操作？
ServiceStack's HttpListener hosts預計將託管根/路徑，因爲正常使用情況是讓每個自託管服務在不同的自定義端口上可用。
由於它目前不支持在/ custompath中託管，因此您必須在所有服務路由上指定/api/前綴。
Add an issue如果您想查看自定義路徑的託管支持。
我找到了解決方法。我只在自我託管下測試過。
創建從RouteAttribute
繼承public class PrefixedRouteAttribute : RouteAttribute
{
public static string Prefix { get; set; }
public PrefixedRouteAttribute(string path) :
base(path)
{
SetPrefix();
}
public PrefixedRouteAttribute(string path, string verbs)
: base(path, verbs)
{
SetPrefix();
}
private void SetPrefix()
{
if (!string.IsNullOrWhiteSpace(Prefix))
{
this.Path = string.Format("/{0}{1}", Prefix, Path);
}
}
}
一個「PrefixedRouteAttribute」類當您創建APPHOST你可以設置你的前綴
PrefixedRouteAttribute.Prefix = "api";
然後，而不是使用[路徑]屬性，使用[PrefixRoute]屬性
[PrefixedRoute("/echo")]
[PrefixedRoute("/echo/{Value*}")]
public class Echo
{
[DataMember]
public string Value { get; set; }
}
This wi然後工作請求
/api/echo
/api/echo/1
這可能可以改進。我不太喜歡我需要通過靜態屬性設置前綴，但我無法想象在我的設置下更好的方法。雖然創建重寫屬性的原理聽起來很合理，但這是重要的一部分。
實際上有一個更簡單的解決方案。在你的web.config，更新您的HTTP處理程序：
<httpHandlers>
<add path="api*" type="ServiceStack.WebHost.Endpoints.ServiceStackHttpHandlerFactory, ServiceStack" verb="*" />
</httpHandlers>
通過上述，您的所有服務的API必須用「/ API /」爲前綴。如果您已經在任何路由中使用了「/ api /」，則現在必須刪除它們，或者必須在呼叫中指定兩次。
這裏亞去..（作爲獎勵，這是你如何把你的服務變成一個插件
using BlogEngineService;
using ServiceStack.WebHost.Endpoints;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace BlogEngineWinService
{
public class AppHost : AppHostHttpListenerBase
{
public AppHost() : base("Self Host Service", typeof(AppHost).Assembly) { }
public override void Configure(Funq.Container container)
{
Plugins.Add(new BlogEngine());
}
}
}
這是你如何自動裝配起來
電話appHost.Routes.AddFromAssembly2(typeof(HelloService).Assembly);是什麼叫擴展到汽車線。
using ServiceStack.WebHost.Endpoints;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ServiceStack.ServiceInterface;
namespace BlogEngineService
{
public class BlogEngine : IPlugin, IPreInitPlugin
{
public void Register(IAppHost appHost)
{
appHost.RegisterService<HelloService>();
appHost.Routes.AddFromAssembly2(typeof(HelloService).Assembly);
}
public void Configure(IAppHost appHost)
{
}
}
}
這就是你如何標記服務類給它一個前綴。 只要選中類具有這種屬性
using ServiceStack.DataAnnotations;
using ServiceStack.ServiceHost;
using ServiceStack.ServiceInterface;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace BlogEngineService
{
public class Hello
{
[PrimaryKey]
public string Bob { get; set; }
}
public class HelloResponse
{
public string Result { get; set; }
}
[PrefixedRoute("/test")]
public class HelloService : Service
{
public object Any(Hello request)
{
return new HelloResponse { Result = "Hello, " + request.Bob};
}
}
}

不錯的主意......我們最終結束了放棄自託管的IIS提供了更多的高級用例的選項（健康監控，deamonizing等）。 FWIW ...我通過流暢的界面註冊我的路線PrefixedRoute不會工作無副作用AppHostBase ...但仍然，很好的方法和有趣的，簡單的解決方案。 – Fred 2012-11-30 19:08:15
