In an ASP.NET Core web api project I'm using Simple Injector and JwtBearer tokens. I have defined my custom token Event handler class and have bound it to ASP.NET Core mechanism as below:
private void ConfigureSecurity(IServiceCollection services)
{
var encodedKey = Encoding.UTF8.GetBytes(_config[Konstants.SecretKey]);
var key = new SymmetricSecurityKey(encodedKey);
services.AddTransient<TokenAuthenticationEvents>();
var authentication = services.AddAuthentication(o =>
{
o.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
o.DefaultSignInScheme = JwtBearerDefaults.AuthenticationScheme;
o.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
});
authentication.AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, options =>
{
options.SaveToken = true;
options.EventsType = typeof(TokenAuthenticationEvents);
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateAudience = true,
ValidAudience = _config[Konstants.AudienceKey],
ValidateIssuer = true,
ValidIssuer = _config[Konstants.AuthorityKey],
ValidateIssuerSigningKey = true,
IssuerSigningKey = key,
RequireExpirationTime = true,
ValidateLifetime = true,
};
});
}
Here is my class Token Events:
public class TokenAuthenticationEvents : JwtBearerEvents
{
private readonly ILogger _log;
private readonly IUserManager _users;
public TokenAuthenticationEvents(ILogger log)
{
_log = log ?? throw new ArgumentNullException(nameof(log));
_users = null;
}
public override Task TokenValidated(TokenValidatedContext context)
{
//Some Custom Logic that requires IUserManager
return base.TokenValidated(context);
}
}
I'm using Simple Injector as my DI container
services.AddSimpleInjector(container, options =>
{
options
.AddAspNetCore()
.AddControllerActivation()
.AddViewComponentActivation()
.AddPageModelActivation()
.AddTagHelperActivation();
});
services.EnableSimpleInjectorCrossWiring(container);
services.UseSimpleInjectorAspNetRequestScoping(container);
IUserManager
along with all its dependencies is registered in Simple Injector. if I try to pass in IUserManager
in TokenAuthenticationEvents
an exception is raised that ASP.NET Core could not resolve IUserManager
. So my question is
How do I tell ASP.NET Core DI to get the IUserManager
resolved from Simple Injector? .
Just as Simple Injector cross wires ASP.NET Core components, you can do the same the other way around, although you will have to do this manually. For instance:
services.AddScoped<IUserManager>(c => container.GetInstance<IUserManager>());
This answer doesn't solve your initial problem, but I did notice you are mixing the old Simple Injector ASP.NET Core configuration model with the new. You currently have the following code:
services.AddSimpleInjector(container, options =>
{
options
.AddAspNetCore()
.AddControllerActivation()
.AddViewComponentActivation()
.AddPageModelActivation()
.AddTagHelperActivation();
});
services.EnableSimpleInjectorCrossWiring(container);
services.UseSimpleInjectorAspNetRequestScoping(container);
The calls to EnableSimpleInjectorCrossWiring
and UseSimpleInjectorAspNetRequestScoping
, however, are the old API and will be removed in a future release. Those features are automatically enabled when you call .AddAspNetCore()
. So you can reduce your configuration to the following:
services.AddSimpleInjector(container, options =>
{
options
.AddAspNetCore()
.AddControllerActivation()
.AddViewComponentActivation()
.AddPageModelActivation()
.AddTagHelperActivation();
});
