I use tokens generated by an authentication service for my app. No problems there. Now I have introduced Swashbuckle to document my API an I can authenticate as follows by sending the JWT with every request using this code;
services.AddSwaggerGen(c =>
{
var a = new ApiKeyScheme();
//c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
//{ In = "header", Description = "Please insert JWT with Bearer into field", Name = "Authorization", Type = "apiKey" });
c.OperationFilter<AuthorizationHeaderParameterOperationFilter>();
c.SwaggerDoc("v2", new Info
{
Version = "v2",
Title = "MyTitle",
Description = "An interface for ...",
TermsOfService = "None",
Contact = new Contact() { Name = "MyApp", Email = "[email protected]", Url = "www.example.com" }
});
// Set the comments path for the Swagger JSON and UI.
var basePath = AppContext.BaseDirectory;
var xmlPath = Path.Combine(basePath, "cpDataCore.xml");
c.IncludeXmlComments(xmlPath);
});
public class AuthorizationHeaderParameterOperationFilter : IOperationFilter
{
public void Apply(Operation operation, OperationFilterContext context)
{
var filterPipeline = context.ApiDescription.ActionDescriptor.FilterDescriptors;
var isAuthorized = filterPipeline.Select(filterInfo => filterInfo.Filter).Any(filter => filter is AuthorizeFilter);
var allowAnonymous = filterPipeline.Select(filterInfo => filterInfo.Filter).Any(filter => filter is IAllowAnonymousFilter);
if (isAuthorized && !allowAnonymous)
{
if (operation.Parameters == null)
operation.Parameters = new List<IParameter>();
operation.Parameters.Add(new NonBodyParameter
{
Name = "Authorization",
In = "header",
Description = "access token",
Required = true,
Type = "string"
});
}
}
}
Which gives me the following header - as expected
accept:application/json
Accept-Encoding:gzip, deflate, br

Although, I am not sure where the Cookie is coming from. That is nothing to do with my code. I just ignore it - so far so good.
The problem is that this means the token has to be entered with every request which is a pain. Ideally, I would want to authenticate using the inbuilt swagger interface - according to several articles, I should be able to do this;
c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
{ In = "header", Description = "Please insert JWT with Bearer into field", Name = "Authorization", Type = "apiKey" });
This works fine, and I can add the token, there just seems to be a step I am missing to add the token to the header of every request. If I just add the auth, then this gives me the following header, which of course fails the authentication.
GET /api/ApprovalItemTypes HTTP/1.1

What else do I need to do in order to get the request to include the token for every subsequent request?
