I didn't realise it, but the <code>CreatedAtAction()</code> method caters for this:

<pre><code>return CreatedAtAction("GetClient", new { id = clientId }, clientReponseModel);
</code></pre>

Ensure that your controller derives from MVC's Controller.

blocks|key|924959|text|在新的ASP.NET+MVC核心中有一个属性Url，它返回IUrlHelper的一个实例。您可以使用以下命令来生成本地URL：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|924960|[HttpPost]

In the new ASP.NET MVC Core there is a property <code>Url</code>, which returns an instance of <code>IUrlHelper</code>. You can use it to generate a local URL by using the following:

<pre><code>[HttpPost]
public async Task&lt;IActionResult&gt; Post([FromBody] Person person)
{
 _DbContext.People.Add(person);
 await _DbContext.SaveChangesAsync();

 return Created(Url.RouteUrl(person.Id), person.Id);
}

It provides the requested functionality.

 public async Task&lt;IActionResult&gt; Get(int id, CancellationToken cancellationToken = default(CancellationToken))

And my POST action uses that route name to return the URL

<pre><code> [HttpPost]

 var url = Url.RouteUrl("GetOrganizationGroupByIdRoute", new { id = item.Id }, Request.Scheme, Request.Host.ToUriComponent());

blocks|key|644234|text|我根据web服务器上提供的Uri使用这个简单的近似：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|644235|[HttpPost]
[Route("")]
public+IHttpActionResult+AddIntervencion(MyNS.MyType+myObject)+{
++return+Created<MyNS.MyType>(Request.RequestUri+%2B+"/"+%2B+myObject.key,+myObject);

I use this simple approximation based on the Uri being served at the web server:

<pre><code>[HttpPost]
[Route("")]
public IHttpActionResult AddIntervencion(MyNS.MyType myObject) {
 return Created&lt;MyNS.MyType&gt;(Request.RequestUri + "/" + myObject.key, myObject);
}
</code></pre>

In Web Api 2.2, we could return the location header URL by returning from controller as follows:

<pre><code>return Created(new Uri(Url.Link("GetClient", new { id = clientId })), clientReponseModel);
</code></pre>

<code>Url.Link(..)</code> would resolve the resource URL accordingly based on the controller name <code>GetClient</code>:

<a href="https://i.stack.imgur.com/RtHSn.png" rel="noreferrer"><img src="https://i.stack.imgur.com/RtHSn.png" alt="Location header"></a>

In ASP.NET 5 MVC 6's Web Api, <code>Url</code> doesn't exist within the framework but the <code>CreatedResult</code> constructor does have the location parameter:

<pre><code>return new CreatedResult("http://www.myapi.com/api/clients/" + clientId, journeyModel);
</code></pre>

How can I resolve this URL this without having to manually supply it, like we did in Web API 2.2?
