Get raw URL from Microsoft.AspNet.Http.HttpRequest

Question

The HttpRequest class in Asp.Net 5 (vNext) contains (amongst other things) parsed details about the URL for the request, such as Scheme, Host

Answer 1

This extension works for me:

using Microsoft.AspNetCore.Http;

    public static class HttpRequestExtensions
    {
        public static string GetRawUrl(this HttpRequest request)
        {
            var httpContext = request.HttpContext;
            return $"{httpContext.Request.Scheme}://{httpContext.Request.Host}{httpContext.Request.Path}{httpContext.Request.QueryString}";
        }
    }

Answer 2

The following extension method reproduces the logic from the pre-beta5 UriHelper:

public static string RawUrl(this HttpRequest request) {
    if (string.IsNullOrEmpty(request.Scheme)) {
        throw new InvalidOperationException("Missing Scheme");
    }
    if (!request.Host.HasValue) {
        throw new InvalidOperationException("Missing Host");
    }
    string path = (request.PathBase.HasValue || request.Path.HasValue) ? (request.PathBase + request.Path).ToString() : "/";
    return request.Scheme + "://" + request.Host + path + request.QueryString;
}

Answer 3

In .NET Core razor:

@using Microsoft.AspNetCore.Http.Extensions
@Context.Request.GetEncodedUrl() //Use for any purpose (encoded for safe automation)

You can also use instead of the second line:

@Context.Request.GetDisplayUrl() //Use to display the URL only

Answer 4

Add the Nuget package / using:

using Microsoft.AspNetCore.Http.Extensions; 

(In ASP.NET Core RC1 this was in Microsoft.AspNet.Http.Extensions)

then you can get the full http request url by executing:

var url = httpContext.Request.GetEncodedUrl();

or

var url = httpContext.Request.GetDisplayUrl();

depending on the purposes.

Answer 5

The other solutions did not fit well my needs because I wanted directly an URI object and I think it is better to avoid string concatenation (also) in this case so I created this extension methods than use a UriBuilder and works also with urls like http://localhost:2050:

public static Uri GetUri(this HttpRequest request)
{
    var uriBuilder = new UriBuilder
    {
        Scheme = request.Scheme,
        Host = request.Host.Host,
        Port = request.Host.Port.GetValueOrDefault(80),
        Path = request.Path.ToString(),
        Query = request.QueryString.ToString()
    };
    return uriBuilder.Uri;
}

In ASP.NET 5 beta5:

Microsoft.AspNet.Http.Extensions.UriHelper.Encode(
    request.Scheme, request.Host, request.PathBase, request.Path, request.QueryString);
