C#通过url调用webservice

routing web-services wcf asp.net-mvc c#

Rob · 技术社区 · 14 年前

我在global.asax上注册了以下路线;

routes.MapRoute(
                "ServiceHandler",
                "{*path}/{*.svc}",
                new { Url = "Services/Service.svc/GetLatestTweets" }
                );

http://www.domainname.com/Services/Service.svc/GetLatestTweets

当我使用上面提到的注册路由时,下面添加的stackstrace出现错误。

也许我错过了什么,但你似乎可以

        routes.MapRoute(
            "ServiceHandler",
            "Services/{service}.svc/{*path}",
            new { controller = "services", action = "ParseAndExecuteServiceCall" service = "TwitterService", path = "GetLatestTweets" }
            );

另外,对于下面关于.svc与.mvc处理程序的注释的响应-没有任何东西可以限制您重写IHttpHandler以便执行此操作,您需要重写IRouteHandler In的GetHttpHandler()方法。。。然后你可以做任何你想要的处理。

你不能做到这一点。这个 .svc 为了处理WCF,扩展已经用与MVC非常不同的处理程序注册。如果你试图改变它的服务永远不会工作。您可能需要从控制器操作调用web服务,该操作将充当网桥。
