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

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;
}
