\u015eimdi, her\u015feyden \u00f6nce yukar\u0131daki g\u00f6rseli incelersek e\u011fer SignalR uygulamas\u0131n\u0131n client ile server aras\u0131ndaki ili\u015fkiden ibaret oldu\u011funu ve ilk etapta server’\u0131n in\u015fa edilip ard\u0131ndan ona uygun client tasar\u0131m\u0131n\u0131n yap\u0131lmas\u0131 gerekti\u011fini s\u00f6yleyebiliriz. O y\u00fczden bu makalemizde server’\u0131n in\u015fas\u0131n\u0131 ele alacak, bir sonraki i\u00e7eri\u011fimizde ise bu server’a uygun client tasar\u0131m\u0131n\u0131n nas\u0131l olaca\u011f\u0131n\u0131 konu\u015faca\u011f\u0131z.<\/p><\/div>\n

SignalR server uygulamas\u0131n\u0131 olu\u015fturabilmek i\u00e7in Visual Studio edit\u00f6r\u00fc \u00fczerinden bir Asp.NET Core – Web API yahut MVC uygulamas\u0131n\u0131n olu\u015fturulmas\u0131 yeterli olacakt\u0131r ve ekstradan bir k\u00fct\u00fcphanenin y\u00fcklenmesine gerek kalmaks\u0131z\u0131n SignalR direkt olarak uygulama \u00fczerinde konfig\u00fcre edilebilir vaziyette dahili gelecektir.<\/p>\n
Bizler pratiksel a\u00e7\u0131dan \u00f6rneklendirmeye Asp.NET Core – Web API \u00fczerinden devam edece\u011fiz. Bu temel haz\u0131rl\u0131ktan sonra ad\u0131m ad\u0131m a\u015fa\u011f\u0131daki \u00f6nergeleri uygulay\u0131n\u0131z;<\/p>\n

\nSignalR’\u0131n kalbinde ‘Hub’ dedi\u011fimiz merkezi yap\u0131lar var demi\u015ftik. Client ile server aras\u0131ndaki t\u00fcm veri ak\u0131\u015f\u0131 bu hub’lar \u00fczerinden ger\u00e7ekle\u015ftirilmektedir. \u00d6z\u00fcnde hub’lar birer class’t\u0131r. Bu y\u00fczden bu class’lar\u0131n uygun yerde tutulmas\u0131 proje tasar\u0131m\u0131 a\u00e7\u0131s\u0131ndan zaruridir. Bunun i\u00e7in uygulaman\u0131n ana dizininde ‘Hubs’ isminde bir klas\u00f6r olu\u015fturularak i\u015fe ba\u015flanabilir.

\nOlu\u015fturulan klas\u00f6r i\u00e7erisine hub’lar\u0131m\u0131z\u0131 olu\u015fturaca\u011f\u0131z. Bizler \u00f6rneklendirme a\u00e7\u0131s\u0131ndan ‘MyHub’ isminde bir class eklemi\u015f bulunmaktay\u0131z.\n<\/li>\n

\nBir class’\u0131n hub olabilmesi i\u00e7in Microsoft.AspNetCore.SignalR<\/em> k\u00fct\u00fcphanesindeki ‘Hub’ s\u0131n\u0131f\u0131ndan t\u00fcremesi laz\u0131md\u0131r.<\/p>\n\r\n public class MyHub : Hub\r\n {\r\n }\r\n<\/pre>\n
Yukar\u0131daki \u00f6rnekte oldu\u011fu gibi ‘MyHub’ s\u0131n\u0131f\u0131 ‘Hub’tan t\u00fcretildi\u011fi i\u00e7in art\u0131k bir hub s\u0131n\u0131f\u0131 olmu\u015ftur. Dolay\u0131s\u0131yla bu s\u0131n\u0131f client taraf\u0131ndan tetiklendi\u011finde SignalR mekanizmas\u0131 sayesinde server’\u0131n da client’\u0131 tetiklemesini sa\u011flayacakt\u0131r.\n<\/li>\n
Ad\u0131m 3<\/strong>
\n‘MyHub’ s\u0131n\u0131f\u0131n\u0131n i\u00e7erisine client’lara bilgi\/veri\/mesaj g\u00f6nderebilmesi i\u00e7in bir metot olu\u015fturulmas\u0131 gerekmektedir. Bizler \u015fimdilik bu metoda ‘SendMessage’ ismini verebiliriz.<\/p>\n
Bunun i\u00e7in a\u015fa\u011f\u0131daki \u00f6rne\u011fi inceleyiniz;<\/p>\n
\r\n public class MyHub : Hub\r\n {\r\n public async Task SendMessageAsync(string message)\r\n {\r\n await Clients.All.SendAsync("receiveMessage", message);\r\n }\r\n }\r\n<\/pre>\n
‘SendMessageAsync’ metodu tetiklendi\u011finde ‘Clients<\/em>‘ property’si \u00fczerinden ‘receiveMessage’ isimli metoda subscribe\/abone olan ‘All<\/em>‘ yani t\u00fcm client’lara ilgili mesaj g\u00f6nderilecektir.<\/p>\n
Burada ‘Clients’ property’sine dikkatinizi \u00e7ekmek istiyorum. Bu property, ‘Hub’ base class’\u0131ndan gelmekte ve bilgi trafi\u011finde client’lar\u0131 temsil etmektedir. ‘Clients.All’ komutu ise ad\u0131 \u00fczerinde t\u00fcm client’lara kar\u015f\u0131l\u0131k gelmektedir. SignalR mekanizmas\u0131, ‘SendAsync’ fonksiyonu i\u00e7erisinde tan\u0131mlanm\u0131\u015f olan de\u011fere kar\u015f\u0131l\u0131k(receiveMessage) client’lar da subscribe olunan bir metot beklemekte ve hub \u00fczerinden ‘SendMessageAsync’e herhangi bir tetikleme oldu\u011fu vakit direkt olarak client’lar\u0131 da ilgili fonksiyon \u00fczerinden bilgilendirmektedir.\n<\/li>\n

\nT\u00fcm bu i\u015flemler neticesinde ‘Startup.cs’ dosyas\u0131na a\u015fa\u011f\u0131daki konfig\u00fcrasyonlar\u0131n yap\u0131lmas\u0131 gerekmektedir.<\/p>\n
\r\n public class Startup\r\n {\r\n public void ConfigureServices(IServiceCollection services)\r\n {\r\n services.AddControllers();\r\n services.AddSignalR();\r\n }\r\n\r\n public void Configure(IApplicationBuilder app, IWebHostEnvironment env)\r\n {\r\n if (env.IsDevelopment())\r\n {\r\n app.UseDeveloperExceptionPage();\r\n }\r\n\r\n app.UseRouting();\r\n\r\n app.UseEndpoints(endpoints =>\r\n {\r\n endpoints.MapControllers();\r\n endpoints.MapHub<MyHub>("\/myhub");\r\n });\r\n }\r\n }\r\n<\/pre>\n
Yukar\u0131daki ayarlara g\u00f6z atarsan\u0131z e\u011fer yap\u0131lmas\u0131 gereken sadece ‘ConfigureServices’ i\u00e7erisinde 6.<\/strong><\/em> sat\u0131rda oldu\u011fu gibi ‘AddSignalR’ servisini \u00e7a\u011f\u0131rmak ve ‘Configure’ i\u00e7erisinde ise 21.<\/strong><\/em> sat\u0131rdaki gibi tasarlanan hub’un endpoint’ini ayarlamakt\u0131r. Burada tan\u0131mlanan endpoint `'https:\/\/localhost:5001\/myhub'<\/strong><\/code> \u015feklinde olacakt\u0131r.\n<\/li>\n<\/ul>\n`
`Client taraf\u0131ndan Hub’a g\u00f6nderilen her bir istek neticesinde ilgili s\u0131n\u0131ftan yeni bir nesne olu\u015fturulacakt\u0131r. Dolay\u0131s\u0131yla global tan\u0131mlanan t\u00fcm property yahut field’lar\u0131n static<\/u> tan\u0131mlanmas\u0131 gerekmektedir.<\/em><\/p><\/blockquote>\n`
`\u0130\u015fte bu kadar basit… SignalR’da en sade haliyle bir hub’\u0131 a\u011faya kald\u0131rmak bu kadar sade ve kolayd\u0131r. Bir sonraki i\u00e7eri\u011fimizde konumuz, tan\u0131mlad\u0131\u011f\u0131m\u0131z bu server ile ileti\u015fim kuran client tasar\u0131m\u0131 olacakt\u0131r.<\/p>\n`
