Instead of
services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();
you can use special method
services.AddHttpContextAccessor();
from Microsoft.AspNetCore.Http what does exacly the same thing.
from authorization.
Here's an alternative way to do it:
public class MyReq : IAuthorizationRequirement
{
private readonly IHttpContextAccessor accessor;
public MyReq(IHttpContextAccessor accessor)
{
this.accessor = accessor;
}
public Task Authorize(AuthorizationContext context)
{
return Task.CompletedTask;
}
}
public static class GraphQLAuthExtensions
{
public static void AddGraphQLAuth(this IServiceCollection services, Action<AuthorizationSettings, IServiceProvider> configure)
{
services.AddHttpContextAccessor();
services.AddTransient<IAuthorizationEvaluator, AuthorizationEvaluator>();
services.AddTransient<IValidationRule, AuthorizationValidationRule>();
services.AddTransient<MyReq>();
services.TryAddTransient(s =>
{
var authSettings = new AuthorizationSettings();
configure(authSettings, s);
return authSettings;
});
}
}
public void ConfigureServices(IServiceCollection services)
{
services.AddGraphQLAuth((_, s) =>
{
_.AddPolicy("SomePolicy", p => p.AddRequirement(s.GetService<MyReq>()));
});
}
from authorization.
I ended adding to my GraphQLUserContext
(which implements IProvideClaimsPrincipal
) a HttpContext
property. This property is being set when constructing it on the GraphQLUserContextBuilder
(as HttpContext
is a parameter of the method BuildUserContext
).
Then, when implementing my IAuthorizationRequirement
on the Authorize
method I can access the registered service from the HttpContext
doing:
HttpContext httpContext = ((GraphQLUserContext)context.UserContext).HttpContext;
var myService = (IMyService)httpContext.RequestServices.GetService(typeof(IMyService));
Is there a better way of doing so?
from authorization.
I updated IAuthorizationEvaluator
in the example to be registered as Transient. Otherwise AuthorizationSettings
would become a singleton indirectly.
from authorization.
Enabling scope validation on DI-container may help to find such problems.

Thanks! I'll do it this way
from authorization.
this is incredibly helpful @joacoleza , do you have an example of how you added the service you want injected to the httpcontext and how you retrieve it out of the httpcontext? i am getting some type errors
from authorization.
for example in my AddGraphQLAuth i have
services.AddHttpContextAccessor(); services.AddTransient<MyServiceToBeInjected>();
and in my requirement i attempt to access it by
var service = accessor.HttpContext.RequestServices.GetService<MyServiceToBeInjected>();
from authorization.

I no longer have access to the code where this was implemented. Sorry I couldn’t be more help.
