What is the alternate to get the current Url in Asp.net core View

Question

I am currently migrating MVC Project to Asp.Net Core Project where in Layout page i used one piece of code to get the current base url.

e.g: If i run MVC application hosted in IIS server then i used Virtual directory to have the MVC application like below:

https://mydomain/myMVCApplication/Login

Then using below code in view i can get the Url till Virtual directory

https://mydomain/myMVCApplication/

 var baseUrl = @Html.Raw(System.Web.HttpUtility.JavaScriptStringEncode(new Uri(new Uri(this.Context.Request.Url.GetLeftPart(UriPartial.Authority)), Url.Content("~/")).ToString(), true));

But when migrate in asp.net core view then Here Context.Request.Url where Url is not a property of Context.Request.

Please suggest here to fix above issue and get the same result.

In Asp.net Core application, you could try to get the URL using the Microsoft.AspNetCore.Http.HttpRequest class or the Microsoft.AspNetCore.Http.Extensions. Then, using ViewData to store the URL in the action method, and display the url on the View Page.

Use the Microsoft.AspNetCore.Http.HttpRequest class

     ViewData["Message"] = $"{this.Request.Scheme}://{this.Request.Host}{this.Request.PathBase}";

or

     ViewData["Message"] = $"{this.Request.Scheme}://{this.Request.Host}{this.Request.Path}";

Use the Microsoft.AspNetCore.Http.Extensions

Using the following code:

     var displayUrl = UriHelper.GetDisplayUrl(Request);
     var urlBuilder =
     new UriBuilder(displayUrl)
     {
         Query = null,
         Fragment = null
     };
     string url = urlBuilder.ToString();
     ViewData["Message"] = url;

Code in the View page:

@{ 
    if (ViewData["Message"] != null)
    {
        @ViewData["Message"]
    }; 
}

You can try this Microsoft.AspNetCore.Http.Extensions.UriHelper.GetFullUrl(Request)

You can use this

@{
var baseUrl = HttpContext.Request.IsHttps ? $"https://{HttpContext.Request.Host}" : $"http:{HttpContext.Request.Host}"
}

curly braces inside double quotes is not providing the correct format. kindly modify your code and provide.

I am using string interpolation with $, curly braces should work, can you paste what error are you facing?

When i used the suggested code then i found like there was compilation error in HttpContext class. I added refrence in top of view inject Microsoft.AspNetCore.Http.IHttpContextAccessor HttpContextAccessor then used like this: var baseUrl = HttpContextAccessor.HttpContext.Request.IsHttps ? $"https://{HttpContext.Request.Host}" : $"http:{HttpContext.Request.Host}" and getting console error: Unexpected string. this code i used inside javascript. Please have it checked.

Request.Host is providing only the domain name not with domain and virtual directory. Using Request.Host with Request.PathBase providing the correct result as expected.

HttpContext.Request.IsHttps can give you fake result in case you host an app behind load balancing. Better to use Request.Scheme.
