I see one missing point: reset token after LoginAsync()

There is a way to update the service with the token from client component code?

Your DefaultCallOptionsFactory decides which token will be used.

class ServiceModelGrpcClientOptions
{
	Func<CallOptions> DefaultCallOptionsFactory { get; set; }
}

CallOptionsFactory is a function. On each call from any proxy created by the ClientFactory the infrastructure asks CallOptionsFactory for default CallOptions.

Here is your example adapted for DefaultCallOptionsFactory:

Setup:

class JwtTokenContainer : IJwtTokenContainer
{
    private string _token;

    public string GetToken() => _token;

    public void SetToken(string value) => _token = value;
}

services.AddSingleton<IJwtTokenContainer, JwtTokenContainer>();

services.AddSingleton<IClientFactory>(provider =>
{
	Func<CallOptions> callOptionsFactory = () => new CallOptions(new Metadata
	{
		{ "Authorization", "Bearer " + provider.GetRequiredService<IJwtTokenContainer>().GetToken() }
	});

	return new ClientFactory(new ServiceModelGrpcClientOptions
	{
		DefaultCallOptionsFactory = callOptionsFactory
	});
});

services.AddSingleton<ChannelBase>(provider =>
{
	var httpClient = new HttpClient(new GrpcWebHandler(GrpcWebMode.GrpcWeb, new HttpClientHandler()));
	return GrpcChannel.ForAddress(new Uri(builder.HostEnvironment.BaseAddress), new GrpcChannelOptions() { HttpClient = httpClient });
});

services.AddTransient<IAuthenticationGrpcService>(provider =>
{
	var channel = provider.GetRequiredService<ChannelBase>();
	var clientFactory = provider.GetRequiredService<IClientFactory>();

	return clientFactory.CreateClient<IAuthenticationGrpcService>();
});

Client code:

[Inject]
private IAuthenticationGrpcService Authentication { get; set; }

[Inject]
private IJwtTokenContainer TokenContainer { get; set; }

...
var res = await Authentication.LoginAsync(request);
if (res.Result)
{
   // all subsequent calls will be authenticated
   TokenContainer.SetToken(res.AccessToken);

   await GrpcService.Authentication.LogoutAsync();

   // all subsequent calls will be anonymous
   TokenContainer.SetToken(null);
}

Hi @Gambero81,

yes it's possible, see example.

Thanks @max-ieremenko,

I use a blazor wasm client, so i have the accessToken on client, after the login call.

There is a way to update the service with the token from client component code?

Actually on client i can have an injected grpc service, but it implement only the interface grpc methods and does not have properties related to DefaultCallOptions.

I solved setting the access token on default request headers of http client.
There is a better solution?

Program.cs:

builder.Services.AddSingleton(services =>
            {
                var httpClient = new HttpClient(new GrpcWebHandler(GrpcWebMode.GrpcWeb, new HttpClientHandler()));
                var channel = GrpcChannel.ForAddress(new Uri(builder.HostEnvironment.BaseAddress), new GrpcChannelOptions() { HttpClient = httpClient });
                var clientFactory = new ClientFactory();

                return new GrpcService(httpClient)
                {
                    Authentication = clientFactory.CreateClient<IAuthenticationGrpcService>(channel)
                };
            });

Client code:

[Inject]
private Services.GrpcService GrpcService { get; set; }
...
var res = await GrpcService.Authentication.LoginAsync(request);
if (res.Result)
{
   GrpcService.HttpClient.DefaultRequestHeaders.Add("Authorization", $"Bearer {res.AccessToken}");

   await GrpcService.Authentication.LogoutAsync();
}
