Creating a proxy to another web api with Asp.net core

Question

I\'m developing an ASP.Net Core web application where I need to create a kind of \"authentication proxy\" to another (external) web service.

What I mean by authentic

Answer 1

I had luck using twitchax's AspNetCore.Proxy NuGet package, but could not get it to work using the ProxyRoute method shown in twitchax's answer. (Could have easily been a mistake on my end.)

Instead I defined the mapping in Statup.cs Configure() method similar to the code below.

app.UseProxy("api/someexternalapp-proxy/{arg1}", async (args) =>
{
    string url = "https://someexternalapp.com/" + args["arg1"];
    return await Task.FromResult(url);
});
