具有相同名称但不同HTTP方法的Web API自定义路由

Question

我们正在尝试在API上实现VersionedRoutes，并在类中声明我们的路由：

new VersionedRoute(
    version,
    "GetRiskReports",
    "/Members/{id}/Cpin/RiskReports",
    new RouteValueDictionary
    {
        {"controller", "Members"},
        {"action", "GetRiskReports"},
        {"id", RouteParameter.Optional}
    }),
new VersionedRoute(
    version,
    "PostRiskReports",
    "/Members/{id}/Cpin/RiskReports",
    new RouteValueDictionary
    {
        {"controller", "Members"},
        {"action", "PostRiskReports"},
        {"id", RouteParameter.Optional}
    })

控制器方法声明如下：

[HttpGet]
public HttpResponseMessage GetRiskReports(int id)

[HttpPost]
public HttpResponseMessage PostRiskReports(int id)

显然此时，对url / Members / 123 / Cpin / RiskReports的GET请求路由到第一个路由ok，但是POST请求无法路由，因为它匹配第一个路由但是控制器方法被标记仅作为GET。无论如何都要将HTTP方法添加到自定义路由。客户端不想更改路由名称。

在 RouteConfig.cs 中，注册此配置：

config.Routes.MapHttpRoute("GetRiskReports", "Members/{id}/Cpin/RiskReports" ,
      new {
             controller = "Members",
             action = "GetRiskReports"
      },
      new {
            HttpMethod = new HttpMethodConstraint(HttpMethod.Get)
       }
);

config.Routes.MapHttpRoute("PostRiskReports", "Members/{id}/Cpin/RiskReports" ,
      new {
             controller = "Members",
             action = "PostRiskReports"
      },
      new {
            HttpMethod = new HttpMethodConstraint(HttpMethod.Post)
       }
);
