是否有可能在DNN的路由映射器中添加多个路由

Question

我已经实现了一个模块,我将其分为两部分:

1. 一个Web项目:
   将我的UI页面作为ascx和ajax调用来触发我的Web API并从中获取数据.
2. 类库:
   具有我的API控制器和路由映射器类.ALl工作正常,但浏览器处理错误为"404".这意味着URL Not Found.我很困惑,因为我错了.

这是我的路由器映射器类: -

using DotNetNuke.Web.Api;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI.WebControls;

namespace NewController 
{
   public class RouteMapper : IServiceRouteMapper
    {
        public void RegisterRoutes(IMapRoute mapRouteManager)
        {
            mapRouteManager.MapHttpRoute("NewController", "default", "{controller}/{action}",
                new[] { "NewController" });
        }
    }
}

我已多次检查我的命名空间和文件夹名称,但没有发现任何错误.

My Controller namespace is like below:-
using DotNetNuke.Common.Utilities;
using DotNetNuke.Web.Api;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;

namespace NewController
{
    public class NewInfoController : DnnApiController
    {
        [AllowAnonymous]
        [HttpGet]
        public HttpResponseMessage HelloWorld()
        {
            return Request.CreateResponse(HttpStatusCode.OK, "Hello World!");
        }
    }
}

以正确的方式获取URL以及: - curl'http:// localhost/dnn7/DesktopModules/NewController/API/NewInfo/HelloWorld '

要么

问题是因为我有多个API控制器？我需要配置多个路由吗？如果是的话怎么样？

Answer 1

首先,我认为你可能对路由有误解.看起来您在网址中使用了命名空间名称.除非你的模块被称为'NewController',否则你的网址将不起作用.DNN路由与Web Api路由非常相似,只是您必须指定模块文件夹名称/DesktopModules/<moduleFolderName>/API/.因此,如果您调用了一个模块'MyModule'并且您的控制器位于名为的名称空间中'NewController',那么该地址就是

' http:// localhost/dnn7/DesktopModules/MyModule/API/NewInfo/HelloWorld '

然后默认路由如下所示;

mapRouteManager.MapHttpRoute(
   "MyModule", 
   "default",
   "{controller}/{action}",
   new[] { "NewController" });

也可以用命名参数重写

mapRouteManager.MapHttpRoute(
   moduleFolderName: "MyModule",
   routeName: "default",
   url: "{controller}/{action}/{id}",
   defaults: new { id = RouteParameter.Optional },
   namespaces: new[] { "NewController" }
   );

关于你的第二部分,你有多条路线吗？当然;

假设您的控制器具有以下操作

namespace NewController
{
    public class NewInfoController : DnnApiController
    {
        [AllowAnonymous]
        [HttpGet]
        public HttpResponseMessage HelloWorld()
        {
            return Request.CreateResponse(HttpStatusCode.OK, "Hello World!");
        }

        [HttpGet]
        public HttpResponseMessage GetItemByName(string name)
        {
            //your logic here
        }

        [HttpGet]
        public HttpResponseMessage GetItemByNameAndLocation(string name, string location)
        {
            //your logic here
        }
    }
}

那么你的路由类看起来像这样

namespace NewController
{
    public class RouteMapper : IServiceRouteMapper
    {
        public void RegisterRoutes(IMapRoute mapRouteManager)
        {
            mapRouteManager.MapHttpRoute(
                moduleFolderName: "MyModule",
                routeName: "itemByName",
                url: "{controller}/{action}/{name}",
                defaults: new { name = "" },
                namespaces: new[] { "NewController" }
            );

            mapRouteManager.MapHttpRoute(
                moduleFolderName: "MyModule",
                routeName: "itemByNameAndLocation",
                url: "{controller}/{action}/{name}/{location}",
                defaults: new { name = "", location = "" },
                namespaces: new[] { "NewController" }
            );

            mapRouteManager.MapHttpRoute(
                moduleFolderName: "MyModule",
                routeName: "default",
                url: "{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional },
                namespaces: new[] { "NewController" }
            );
        }
    }
}

现在http://localhost/dnn7/DesktopModules/MyModule/API/NewInfo/GetItemByName/someName将由第一条路线http://localhost/dnn7/DesktopModules/MyModule/API/NewInfo/GetItemByNameAndLocation/someName/someLocation处理,将由第二条路线处理.任何与这两者不匹配的东西都将由最后default一条路线处理.记住路由中的层次结构很重要!

如果你想缩短要说的网址怎么办？

HTTP://本地主机/ dnn7/DesktopModules/MyModule的/ API /读取/ someName

和

HTTP://本地主机/ dnn7/DesktopModules/MyModule的/ API/fetchByNameAndLocation/someName/someLocation

注意我们没有指定Controller和Action.我们所要做的就是将前两条路线改为

mapRouteManager.MapHttpRoute(
    moduleFolderName: "MyModule",
    routeName: "itemByName",
    url: "fetch/{name}",
    defaults: new { controller = "NewInfo", action = "GetItemByName", name = "" },
    namespaces: new[] { "NewController" }
);

mapRouteManager.MapHttpRoute(
     moduleFolderName: "MyModule",
     routeName: "itemByNameAndLocation",
     url: "fetchByNameAndLocation/{name}/{location}",
     defaults: new { controller = "NewInfo", action = "GetItemByNameAndLocation", name = "", location = "" },
     namespaces: new[] { "NewController" }
);

如果您熟悉Web Api,您会发现DNN的服务路由非常相似,因为它只是基础Web Api路由的包装器.祝好运!
