如何在ASP.NET MVC中找到动作的绝对URL？

How do I find the absolute url of an action in ASP.NET MVC?

我需要这样做：

1 2	<script type="text/javascript"> token_url ="http://example.com/your_token_url";

我使用的是MVC的beta版本，但我不知道如何获取操作的绝对URL。我想这样做：

1	<%= Url.AbsoluteAction("Action","Controller")) %>

是否有帮助程序或页面方法？

单击此处获取更多信息，但本质上不需要扩展方法。它已经烤好了，只是不是很直观。

1	Url.Action("Action", null, null, Request.Url.Scheme);

namespace System.Web.Mvc
{
public static class HtmlExtensions
{
public static string AbsoluteAction(this UrlHelper url, string action, string controller)
{
Uri requestUrl = url.RequestContext.HttpContext.Request.Url;

string absoluteAction = string.Format(
"{0}://{1}{2}",
requestUrl.Scheme,
requestUrl.Authority,
url.Action(action, controller));

return absoluteAction;
}
}
}

那就这样说吧

1	<%= Url.AbsoluteAction("Dashboard","Account")%>

编辑-重新分析注释

对被接受的答案最乐观的评论是This answer is the better one, this way Resharper can still validate that the Action and Controller exists.，所以这里有一个例子，你如何获得相同的行为。

使用@查里诺作为向导的回答，我想出了这个。

urlhelper的ASP.NET MVC文档显示url.action将在传入主机名和协议时返回完全限定的url。我创建了这些帮助器来强制提供主机名和协议。多个重载镜像URL的重载。操作：

我不确定是否有一种内置的方法来实现它，但是您可以使用自己的htmlhelper方法。

namespace System.Web.Mvc
{
public static class HtmlExtensions
{
public static string AbsoluteAction(this HtmlHelper html, string actionUrl)
{
Uri requestUrl = html.ViewContext.HttpContext.Request.Url;

string absoluteAction = string.Format("{0}://{1}{2}",
requestUrl.Scheme,
requestUrl.Authority,
actionUrl);

return absoluteAction;
}
}
}

那就这样说吧

1	<%= Html.AbsoluteAction(Url.Action("Dashboard","Account"))%> ?

HTHs查尔斯

带参数的完整答案是：

1	var url = Url.Action("ActionName","ControllerName", new { id ="arg_value" }, Request.Url.Scheme);

这将产生一个绝对的URL

结果相同，但更清晰(无字符串连接/格式)：

{

UriBuilder realmUri = new UriBuilder(contextUri) { Path = url.RequestContext.HttpContext.Request.ApplicationPath, Query = null, Fragment = null };
return realmUri.Uri;
}

public static string ActionAbsolute(this UrlHelper url, string actionName, string controllerName)
{
return new Uri(GetBaseUrl(url), url.Action(actionName, controllerName)).AbsoluteUri;
}

env: dotnet core version 1.0.4

1	Url.Action("Join",null, null,Context.Request.IsHttps?"https":"http");
