如何绕过例外的ASP.NET Web API中发现多个操作 [英] How to bypass the exception multiple actions were found in ASP.NET Web API

问题描述

在试图找到这个问题如下解决方案：

When trying to find solution for this below question:

<一个href=\"http://stackoverflow.com/questions/11724749/mvc-web-api-route-with-default-action-not-working/11725968#11725968\">MVC网页API路由默认动作不灵

主要是我在整个运行问题多个动作被发现。如果路由机制发现与路由匹配的多个动作，就抛出异常500。

Mostly I run across the problem "multiple actions were found". If routing mechanism finds out more than one actions matched with a route, it throws out the exception 500.

例如，有两个动作中Values​​Controller：

For example, there are two actions in ValuesController:

[HttpGet]
public IEnumerable<String> Active()
{
    var result = new List<string> { "active1", "active2" };
    return result;
}

public IEnumerable<string> Get()
{
    return new[] { "value1", "value2" };
}

该比赛与默认路由：

which match with default route:

 routes.MapHttpRoute(
          name: "DefaultApi",
          routeTemplate: "api/{controller}/{id}",
          defaults: new { id = RouteParameter.Optional }
      );

通过

GET: /api/values 

会被发现的错误多个动作。

will get error multiple actions were found.

我的问题：我怎么能选择指定的动作绕过异常多个动作被发现（选择第一个匹配的动作也没关系）

My question: how I can bypass the exception "multiple actions were found" by choosing specified action (choose the first matched action is also okay).

更新1：正在从tugberk的评论更新，这要归功于指出

Update 1: Update from tugberk's comment, thanks to point out.

更新2：正在从迈克的评论更新，似乎这个问题是不正确的多，所以我改变由不提路由约束问路

Update 2: Update from Mike's comment, seems the question is not correct much, so I change the way to ask by not mentioning the routing constraint.

感谢

推荐答案

首先，它不应该是可能的，除非你申请HTTPGET它属性的路线，以配合积极的行动。我会假设你已经做到了。第二件事是，你想要的是不符合逻辑的。你想作一个GET请求，并有两个相同的动作。您现在正在使用基于HTTP的方法，所谓的路由。对于你的情况，我相信所谓的基于动作的路由是最好的。

First of all, it shouldn't be possible for those route to match Active action unless you apply HttpGet attribute on it. I will assume you already did that. The second thing is that what you want is not logical. You would like to make a get request and have two identical actions. You are now using so-called HTTP-method-based routing. For you situation, I am sure that so-called action-based routing is the best.

假设你有以下两个动作：

Assuming you have following two actions:

[HttpGet]
public IEnumerable<String> Active()
{
    var result = new List<string> { "active1", "active2" };
    return result;
}

[HttpGet]
public IEnumerable<string> Retrieve()
{
    return new[] { "value1", "value2" };
}

您路线应该如下：

routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

然后，你可以要求那些具有下列的URI：

Then you can request to those with following URIs:

GET / controllername /检索

GET /controllername/retrieve

GET / controllername /主动

GET /controllername/active
