如何在同一个Global.asax的主机WCF REST服务和WCF数据服务 [英] How to Host WCF REST Service and WCF Data Service in the same global.asax

问题描述

我有一个是通过服务路由在Global.asax中看起来像这样举办一个WCF REST Web服务;

 保护覆盖无效的RegisterRoutes（System.Web.Routing.RouteCollection routeTable）
    {
        routeTable.Add（新ServiceRoute（，新WebServiceHostFactory（），
                       的typeof（UserService的）））;
    }
 

我想知道是否有可能还承载另一个Web服务（这是一个WCF数据服务）在同一应用程序。

 保护覆盖无效的RegisterRoutes（System.Web.Routing.RouteCollection routeTable）
    {
        routeTable.Add（新ServiceRoute（，新WebServiceHostFactory（），
                       的typeof（UserService的）））;
        routeTable.Add（新ServiceRoute（OData的新DataServiceHostFactory（）
                       的typeof（UserDataService）））;
    }
 

试图在我的浏览器导航到的http：//本地主机：端口/ 带来了标准的REST服务优良而导航到的http：//本地主机：端口/ OData的会弹出找不到网页终点

这样做的原因是，我有传统的code在REST服务，我需要保持周围也希望通过数据服务来揭露一些纯粹的数据。

解决方案

事实证明，这是非常简单的，我完全忽略了明显的。

这时候您承载多个服务航线看来你不能在任何航线有一个默认/空航线preFIX，你可以用一个单一的路线。请注意，这是我曾在我的问题上面的UserService的路线。

因此​​，对于这两种服务航线提供航线preFIX允许这两种服务在同一范围内的Global.asax被托管。

提供了code的完整性......

 保护覆盖无效的RegisterRoutes（System.Web.Routing.RouteCollection routeTable）
{
    routeTable.Add（新ServiceRoute（休息，新WebServiceHostFactory（）
                   的typeof（UserService的）））;
    routeTable.Add（新ServiceRoute（OData的新DataServiceHostFactory（）
                   的typeof（UserDataService）））;
}
 

I have a WCF REST web service that is hosted via a service route in global.asax which looks like this;

protected override void RegisterRoutes(System.Web.Routing.RouteCollection routeTable)
    {
        routeTable.Add(new ServiceRoute("", new WebServiceHostFactory(),
                       typeof(UserService)));
    }

I am wondering whether or not it is possible to also host another web service (which is a WCF Data Service) in the same application.

protected override void RegisterRoutes(System.Web.Routing.RouteCollection routeTable)
    {
        routeTable.Add(new ServiceRoute("", new WebServiceHostFactory(),
                       typeof(UserService)));
        routeTable.Add(new ServiceRoute("OData", new DataServiceHostFactory(),
                       typeof(UserDataService)));
    }

Attempting to navigate in my browser to http://localhost:port/ brings up the standard REST service fine whilst navigating to http://localhost:port/OData brings up the 'end point not found page'.

The reason for this is that I have legacy code in the REST service I need to keep around but also want to expose some pure data via the data service.

解决方案

It turns out this was exceedingly simple and I completely overlooked the obvious.

It appears when you are hosting multiple service routes you cannot have a default/empty route prefix on any of the routes as you can with a single route. Note this was what I had in my question above for the UserService route.

Thus providing a route prefix for both service routes allows both services to be hosted within the same global.asax.

Providing code for completeness...

protected override void RegisterRoutes(System.Web.Routing.RouteCollection routeTable)
{
    routeTable.Add(new ServiceRoute("Rest", new WebServiceHostFactory(),
                   typeof(UserService)));
    routeTable.Add(new ServiceRoute("OData", new DataServiceHostFactory(),
                   typeof(UserDataService)));
}
