[Blazor] Blazor API 서버 Example

ValuesController

using HelloEmpty.Models;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;

namespace HelloEmpty.controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class ValuesController : ControllerBase
    {
        [HttpGet]
        public List<HelloMessage> Get()
        {
            List<HelloMessage> message = new List<HelloMessage>();
            message.Add(new HelloMessage() { Message = "Hello Web API 1!" });
            message.Add(new HelloMessage() { Message = "Hello Web API 2!" });
            message.Add(new HelloMessage() { Message = "Hello Web API 3!" });
            return message;
        }
    }
}

get() 이 클라에서 서버로 api/Values 경로로 api 를 쏘면 

서버에서 보낼 내용을 message 에 담아 브라우저에 보낸다

 

 

HelloMessage

namespace HelloEmpty.Models
{
    public class HelloMessage
    {
        public string Message { get; set; }
    }
}

실제 데이터는 Models 에 들어있게 된다

 

 

program 부분인데 이 부분은 디폴트이다

using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace HelloEmpty
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
}

 

 

Startup.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace HelloEmpty
{
    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            //mvc 를 사용하겠다는 것
            //services.AddControllersWithViews();
            services.AddControllers();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();


            //홈페이지 실행할때 어떤 주소로 어떤 부분을 연동하여 실행할지에 대한 부분
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                //endpoints.MapRazorPages();
                //endpoints.MapControllerRoute(name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");
                /*
                endpoints.MapGet("/", async context =>
                {
                    await context.Response.WriteAsync("Hello World!");
                });
                */
            });
        }
    }
}

 

DotNet Core 3.1 버전으로 하면 StartUp.cs 가 생성된다

 

 

실행결과

 

실제 데이터가 JSON 형태로 온것을 알 수 있다
