Geleneksel client yap\u0131lanmas\u0131…<\/p><\/div>
\nYukar\u0131daki geleneksel yap\u0131lanma, gRPC client tasar\u0131mlar\u0131nda y\u00f6netilebilirlik a\u00e7\u0131s\u0131ndan pek tercih edilebilir bir d\u00fczenleme de\u011fildir. Haliyle bizlere merkezi bir konum \u00fczerinden client tasar\u0131m\u0131n\u0131 sa\u011flayacak olan Factory entegrasyonunu tercih edebiliriz.<\/p>\n
Factory Integration’\u0131 kullanabilmek i\u00e7in temel gRPC k\u00fct\u00fcphanelerinin yan\u0131nda Grpc.Net.ClientFactory<\/a> k\u00fct\u00fcphanesinin uygulamaya y\u00fcklenmesi yeterlidir. \u0130lgili entegrasyonu yapabilmek i\u00e7in ‘Startup.cs’ dosyas\u0131nda a\u015fa\u011f\u0131daki gibi AddGrpcClient<\/code> servisinin \u00e7a\u011fr\u0131lmas\u0131 ve temel konfig\u00fcrasyonlar\u0131n yap\u0131lmas\u0131 gerekmektedir.<\/p>\n

Haliyle client ilgili s\u0131n\u0131fa do\u011frudan dependency injection ile eri\u015febilecek ve t\u00fcketebilecektir. \nMisal controller’dan direkt talep edilebilmektedir :<\/p>\n \r\n [Route("api\/[controller]")]\r\n [ApiController]\r\n public class PersonController : ControllerBase\r\n {\r\n readonly PersonClient _personClient;\r\n public PersonController(PersonClient personClient)\r\n {\r\n _personClient = personClient;\r\n }\r\n public async Task<IActionResult> Get()\r\n {\r\n var response = _personClient.GetPersons(new());\r\n while (await response.ResponseStream.MoveNext(new()))\r\n {\r\n Console.WriteLine(response.ResponseStream.Current.Name);\r\n }\r\n return Ok();\r\n }\r\n }\r\n<\/pre>\nYa da custom bir servis taraf\u0131ndan da \u00e7a\u011fr\u0131labilmektedir :<\/p>\n \r\n public class PersonService \r\n {\r\n readonly PersonClient _personClient;\r\n public PersonService(PersonClient personClient)\r\n {\r\n _personClient = personClient;\r\n }\r\n public async Task GetPersons()\r\n {\r\n var response = _personClient.GetPersons(new());\r\n while (await response.ResponseStream.MoveNext(new()))\r\n {\r\n Console.WriteLine(response.ResponseStream.Current.Name);\r\n }\r\n }\r\n }\r\n<\/pre>\nInterceptor Konfig\u00fcrasyonu<\/h6>\nClient’tan gelen \u00e7a\u011fr\u0131lara kar\u015f\u0131l\u0131k interceptor’lar\u0131 a\u015fa\u011f\u0131daki gibi devreye sokabilirsiniz. \nInterceptor :<\/p>\n \r\n public class CustomInterceptor : Interceptor\r\n {\r\n public override AsyncServerStreamingCall<TResponse> AsyncServerStreamingCall<TRequest, TResponse>(TRequest request, ClientInterceptorContext<TRequest, TResponse> context, AsyncServerStreamingCallContinuation<TRequest, TResponse> continuation)\r\n {\r\n Console.WriteLine("Merhaba d\u00fcnya...");\r\n return base.AsyncServerStreamingCall(request, context, continuation);\r\n }\r\n }\r\n<\/pre>\nKonfig\u00fcrasyon :<\/p>\n \r\n services.AddGrpcClient<PersonClient>(o =>\r\n {\r\n o.Address = new Uri("https:\/\/localhost:5001");\r\n })\r\n .AddInterceptor(() => new CustomInterceptor())\r\n .AddInterceptor(() => new CustomInterceptor2());\r\n<\/pre>\nChannel Konfig\u00fcrasyonu<\/h6>\nClient’tan gelen \u00e7a\u011fr\u0131lara istinaden basic d\u00fczeyde bir kimlik do\u011frulama i\u015flemi ger\u00e7ekle\u015ftirebilmek i\u00e7in channel konfig\u00fcrasyonunu a\u015fa\u011f\u0131daki gibi devreye sokabilirsiniz.<\/p>\n \u00d6rne\u011fin, gRPC Server’da base olarak kullan\u0131lan ‘PersonService’in ‘Authorize’ edildi\u011fini varsayal\u0131m.<\/p>\n \r\n [Authorize]\r\n public class PersonService : PersonBase\r\n {\r\n public async override Task<PersonResponse> GetPerson(Empty request, ServerCallContext context)\r\n {\r\n .\r\n .\r\n .\r\n }\r\n public async override Task GetPersons(Empty request, IServerStreamWriter<PersonResponse> responseStream, ServerCallContext context)\r\n {\r\n .\r\n .\r\n .\r\n }\r\n }\r\n<\/pre>\nBu servise eri\u015febilmek i\u00e7in JWT ile istek yap\u0131lacaksa e\u011fer bu iste\u011fi client’ta a\u015fa\u011f\u0131daki gibi ‘ConfigureChannel’ metodu ile yap\u0131land\u0131rmak gerekmektedir.<\/p>\n \r\n services.AddGrpcClient<PersonClient>(o =>\r\n {\r\n o.Address = new Uri("https:\/\/localhost:5001");\r\n })\r\n .AddInterceptor(() => new CustomInterceptor())\r\n .AddInterceptor(() => new CustomInterceptor())\r\n .ConfigureChannel(option =>\r\n {\r\n option.Credentials = ChannelCredentials.Create(new SslCredentials(), CallCredentials.FromInterceptor((context, metadata) =>\r\n {\r\n string jwt = "...";\r\n metadata.Add("Authorization", $"Bearer {jwt}");\r\n return Task.CompletedTask;\r\n }));\r\n });\r\n<\/pre>\nNamed Clients\/\u0130simlendirilmi\u015f Client’lar<\/h6>\nTipik olarak bir gRPC client’\u0131 bir kez IoC’ye kaydedilir ve ard\u0131ndan her ihtiya\u00e7 oldu\u011funda dependency injection ile bu nesne talep edilir.
