构造URL鉴于与属性的路由网页API [英] Construct url in view for Web Api with attribute routing

问题描述

我怎样才能从网页API的网址，我认为？

How can I get the url from web api in my view?

示例（从的 MSDN-博客）：

[RoutePrefix("reviews")]
public class ReviewsController : ApiController
{
    // eg.: /reviews
    [Route]
    public IHttpActionResult Get() { ... }
    // eg.: /reviews/5
    [Route("{reviewId}")]
    public IHttpActionResult Show(int reviewId) { ... }
    // eg.: /reviews/5/edit
    [Route("{reviewId}/edit")]
    public IHttpActionResult Edit(int reviewId) { ... }
}

现在我要建构在我看来/评论/编辑，我该怎么做呢？

Now I want to construct "/reviews/edit" in my view, how can I do this?

我试图创建一个小的扩展方法，但它需要我给每条路由的实际RouteName。有没有我可以（在MVC等）使用，我可以只通过控制器和行动的方法？

I've tried creating a little extension method, but it requires me to give every route an actual "RouteName". Is there a method I can use (like in MVC) where I can just pass the controller and action?

@Url.Action("Edit", "Reviews)

现在我使用（与RouteName）该方法还不允许​​我使用整数作为参数（除非我传递一个默认值）。如果我需要命名我所有的路线，我怎样才能创建一个路由URL，但传中的数据我的要求-portion？我的参数

The method I'm using now (with RouteName) also doesn't allow me to use integers as parameters (unless I pass a default value). If I do need to name all my routes, how can I create a route url, but pass my parameters in the "data"-portion of my request?

目前的方法：

public static string ResolveWebApiRoute(this UrlHelper urlHelper, string routeName, object routeValues = null)
{
    var newRouteValues = new RouteValueDictionary(routeValues);
    newRouteValues.Add("httproute", true);

    return urlHelper.RouteUrl(routeName, newRouteValues);
}

修改

当我用像 Url.RouteUrl（新{控制器= ... =行动...}），它直接重定向到该操作方法（如新{控制器=评论，行动=显示} - ＆GT; /评论/节目，whilest我希望它重定向到 /评论/...

When I used methods like Url.RouteUrl(new { controller = ..., action = ...}), It redirects directly to that action (e.g. new { controller = "Reviews", action = "Show"} --> /reviews/show, whilest I want it to redirect to /reviews/...

推荐答案

生成链接到网页API的路线总是需要一个 RouteName ，所以你应该有类似如下：

Generating links to Web API routes always require a RouteName, so you should have something like below:

[Route("{reviewId}/edit", Name="EditView")]
public IHttpActionResult Edit(int reviewId) { ... }

您可以生成像 /链接点评/ 1 /编辑来的Web API。

You can then generate a link like /reviews/1/editto Web API.

Url.RouteUrl(routeName: "EditView", routeValues: new { httpRoute = true, reviewId = 1 });

或

Url.HttpRouteUrl(routeName: "EditView", routeValues: , reviewId = 1)

请注意这条路线名称必须显式地指定他们不再自动生成像什么@Karhgath是在暗示。这是从RC到RTM版本所做的更改。

Note that route names need to be specified explicitly and they are no longer generated automatically like what @Karhgath is suggesting. This was a change made from RC to RTM version.
