Add Authentication to /swagger/ui/index page - Swagger | Web API | Swashbuckle
Finally, I solved it with DelegtingHandler
, here's how I did it:
Create a file SwaggerAccessMessageHandler.cs
and add it in App_Start
folder.
using System;
using System.Net;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
public class SwaggerAccessMessageHandler : DelegatingHandler
{
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
if (IsSwagger(request) && !Thread.CurrentPrincipal.Identity.IsAuthenticated)
{
HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.Redirect);
// Redirect to login URL
string uri = string.Format("{0}://{1}", request.RequestUri.Scheme, request.RequestUri.Authority);
response.Headers.Location = new Uri(uri);
return Task.FromResult(response);
}
else
{
return base.SendAsync(request, cancellationToken);
}
}
private bool IsSwagger(HttpRequestMessage request)
{
return request.RequestUri.PathAndQuery.Contains("/swagger");
}
}
Next, Wire up the handler in SwaggeConfig.cs
just before enabling Swagger as follows:
GlobalConfiguration.Configuration.MessageHandlers.Add(new SwaggerAccessMessageHandler());
GlobalConfiguration.Configuration.EnableSwagger(c =>
{
...
});
