blocks|key|2231863|text|有一个Url.Action重载，它接受你想要的协议(例如http，https)作为参数-如果你指定了它，你会得到一个完全限定的URL。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2231864|下面是一个在action方法中使用当前请求的协议的示例：|2231865|var+fullUrl+=+this.Url.Action("Edit",+"Posts",+new+{+id+=+5+},+this.Request.Url.Scheme);|code-block|syntax|javascript|2231866|razor+(@Html)也有一个ActionLink方法的重载，您可以在HtmlHelper中使用它来创建锚元素，但它也需要hostName和fragment参数。所以我选择再次使用@Url.Action：|2231867|

There is an overload of Url.Action that takes your desired protocol (e.g. http, https) as an argument - if you specify this, you get a fully qualified URL.

Here's an example that uses the protocol of the current request in an action method:

<pre><code>var fullUrl = this.Url.Action("Edit", "Posts", new { id = 5 }, this.Request.Url.Scheme);
</code></pre>

HtmlHelper (@Html) also has an overload of the ActionLink method that you can use in razor to create an anchor element, but it also requires the hostName and fragment parameters. So I'd just opt to use @Url.Action again:

<pre><code>&lt;span&gt;
 Copy
 &lt;a href='@Url.Action("About", "Home", null, Request.Url.Scheme)'&gt;this link&lt;/a&gt; 
 and post it anywhere on the internet!
&lt;/span&gt;
</code></pre>

blocks|key|1978589|text|正如帕迪提到的：如果您使用显式指定要使用的协议的+UrlHelper.Action()+URL的重载，则生成的将是绝对的和完全限定的，而不是相对的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|CODE|entityRanges|data|1978590|我写了一篇名为How+to+build+absolute+action+URLs+using+the+UrlHelper+class的博客文章，其中我建议出于可读性的考虑编写一个自定义扩展方法：|1978591|///+<summary>

{
++++string+scheme+=+url.RequestContext.HttpContext.Request.Url.Scheme;

++++return+url.Action(actionName,+controllerName,+routeValues,+scheme);
}|code-block|syntax|javascript|1978592|然后，您可以在视图中像这样简单地使用它：|1978593|@Url.AbsoluteAction("Action",+"Controller")|1978594|entityMap|0|LINK|mutability|MUTABLE|url|https://blog.mariusschulz.com/2011/06/30/how-to-build-absolute-action-urls-using-the-urlhelper-class^0|8|G|P|I|1J|J|P|I|0|7|1N|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Z|8|@$9|10|A|11|B|C]|$9|12|A|13|B|C]|$9|14|A|15|B|C]|$9|16|A|17|B|D]]|E|@]|F|$]]|$1|G|3|H|5|6|7|18|8|@]|E|@$9|19|A|1A|1|1B]]|F|$]]|$1|I|3|J|5|K|7|1C|8|@]|E|@]|F|$L|M]]|$1|N|3|O|5|6|7|1D|8|@]|E|@]|F|$]]|$1|P|3|Q|5|K|7|1E|8|@]|E|@]|F|$L|M]]|$1|R|3|-4|5|6|7|1F|8|@]|E|@]|F|$]]]|S|$T|$5|U|V|W|F|$X|Y]]]]

As Paddy mentioned: if you use an overload of <code>UrlHelper.Action()</code> that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative.

I wrote a blog post called <a href="https://blog.mariusschulz.com/2011/06/30/how-to-build-absolute-action-urls-using-the-urlhelper-class" rel="noreferrer">How to build absolute action URLs using the UrlHelper class</a> in which I suggest to write a custom extension method for the sake of readability:

<pre><code>/// &lt;summary&gt;
/// Generates a fully qualified URL to an action method by using
/// the specified action name, controller name and route values.
/// &lt;/summary&gt;
/// &lt;param name="url"&gt;The URL helper.&lt;/param&gt;
/// &lt;param name="actionName"&gt;The name of the action method.&lt;/param&gt;
/// &lt;param name="controllerName"&gt;The name of the controller.&lt;/param&gt;
/// &lt;param name="routeValues"&gt;The route values.&lt;/param&gt;
/// &lt;returns&gt;The absolute URL.&lt;/returns&gt;
public static string AbsoluteAction(this UrlHelper url,
 string actionName, string controllerName, object routeValues = null)
{
 string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;

 return url.Action(actionName, controllerName, routeValues, scheme);
}
</code></pre>

You can then simply use it like that in your view:

<pre><code>@Url.AbsoluteAction("Action", "Controller")
</code></pre>

blocks|key|1981070|text|这个问题是特定于的，但是我相信你们中的一些人会从系统不可知的.NET中受益，这在许多情况下都是有益的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1981071|更新：在页面之外形成url的方法在上面的答案中有很好的描述。|offset|length|style|BOLD|1981072|或者你可以像下面这样做一个线条：|1981073|new+UrlHelper(actionExecutingContext.RequestContext).Action(

This question is specific to ASP .NET however I am sure some of you will benefit of system agnostic javascript which is beneficial in many situations.

UPDATE: The way to get url formed outside of the page itself is well described in answers above. 

Or you could do a oneliner like following:

<pre><code>new UrlHelper(actionExecutingContext.RequestContext).Action(
 "SessionTimeout", "Home", 
 new {area = string.Empty}, 
 actionExecutingContext.Request.Url!= null? 
 actionExecutingContext.Request.Url.Scheme : "http"
);
</code></pre>

from filter or:

<pre><code>new UrlHelper(this.Request.RequestContext).Action(
 "Details", 
 "Journey", 
 new { area = productType }, 
 this.Request.Url!= null? this.Request.Url.Scheme : "http"
);
</code></pre>

However quite often one needs to get the url of current page, for those cases using <code>Html.Action</code> and putting he name and controller of page you are in to me feels awkward. My preference in such cases is to use JavaScript instead. This is especially good in systems that are half re-written MVT half web-forms half vb-script half God knows what - and to get URL of current page one needs to use different method every time.

One way is to use JavaScript to get URL is <code>window.location.href</code> another - <code>document.URL</code>

blocks|key|1978651|text|这可能只是我非常，非常挑剔，但我喜欢只定义常量一次。如果您使用上面定义的任何方法，您的操作常量将被多次定义。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1978652|要避免这种情况，可以执行以下操作：|1978653|++++public+class+Url

++++++++public+override+string+ToString()
++++++++{

This may be just me being really, really picky, but I like to only define constants once. If you use any of the approaches defined above, your action constant will be defines multiple times.

To avoid this, you can do the following:

<pre><code> public class Url
 {
 public string LocalUrl { get; }

 public Url(string localUrl)
 {
 LocalUrl = localUrl;
 }

 public override string ToString()
 {
 return LocalUrl;
 }
 }

 public abstract class Controller
 {
 public Url RootAction =&gt; new Url(GetUrl());

 protected abstract string Root { get; }

 public Url BuildAction(string actionName)
 {
 var localUrl = GetUrl() + "/" + actionName;
 return new Url(localUrl);
 }

 private string GetUrl()
 {
 if (Root == "")
 {
 return "";
 }

 return "/" + Root;
 }

 public override string ToString()
 {
 return GetUrl();
 }
 }
</code></pre>

Then create your controllers, say for example the DataController:

<pre><code> public static readonly DataController Data = new DataController();
 public class DataController : Controller
 {
 public const string DogAction = "dog";
 public const string CatAction = "cat";
 public const string TurtleAction = "turtle";

 protected override string Root =&gt; "data";

 public Url Dog =&gt; BuildAction(DogAction);
 public Url Cat =&gt; BuildAction(CatAction);
 public Url Turtle =&gt; BuildAction(TurtleAction);
 }
</code></pre>

Then just use it like:

<pre><code> // GET: Data/Cat
 [ActionName(ControllerRoutes.DataController.CatAction)]
 public ActionResult Etisys()
 {
 return View();
 }
</code></pre>

And from your .cshtml (or any code)

<pre><code>&lt;ul&gt;
 &lt;li&gt;&lt;a href="@ControllerRoutes.Data.Dog"&gt;Dog&lt;/a&gt;&lt;/li&gt;
 &lt;li&gt;&lt;a href="@ControllerRoutes.Data.Cat"&gt;Cat&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
</code></pre>

This is definitely a lot more work, but I rest easy knowing compile time validation is on my side.

I was having an issue with this, my server was running behind a load balancer. The load balancer was terminating the SSL/TLS connection. It then passed the request to the web servers using http. 

Using the Url.Action() method with Request.Url.Schema, it kept creating a http url, in my case to create a link in an automated email (which my PenTester didn't like).

I may have cheated a little, but it is exactly what I needed to force a https url:

<pre><code>&lt;a href="@Url.Action("Action", "Controller", new { id = Model.Id }, "https")"&gt;Click Here&lt;/a&gt;
</code></pre>

I actually use a web.config AppSetting so I can use http when debugging locally, but all test and prod environments use transformation to set the https value.

Is there a built-in way of getting the full URL of an action?

I am looking for something like <code>GetFullUrl("Action", "Controller")</code> that would return something like <code>http://www.fred.com/Controller/Action</code>.

The reason I am looking for this is to avoid hardcoding URLs in automated emails that are generated so that the URLs can always be generated relative to the current location of the site.
