c# - 如何将 Web API 添加到现有的 ASP.NET MVC Core 6 Web 应用程序

Question

我正在尝试将 Web API 端点添加到现有的 Web 应用程序。我该怎么做呢？ 这是 GitHub 链接 https://github.com/GrindingLife/BHFunctioning

我尝试在 Controller 文件夹中添加 API Controller 的支架。启动后访问 localhost/api 不起作用。我不知道要向 Program.cs 文件添加什么。我见过的所有示例都是startup.cs 文件而不是program.cs

这是我的program.cs文件

using BHFunctioning.Controllers;
using BHFunctioning.Data;
using BHFunctioning.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.FileProviders;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
builder.Services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(connectionString));
builder.Services.AddDatabaseDeveloperPageExceptionFilter();

builder.Services.AddAuthorization(options =>
{
    options.AddPolicy("RequireAdministratorRole",
         policy => policy.RequireRole("Administrator"));
});
builder.Services.AddIdentity<IdentityUser, IdentityRole>(options => options.SignIn.RequireConfirmedAccount = false)
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddRoles<IdentityRole>()
    .AddDefaultUI()
    .AddDefaultTokenProviders();
builder.Services.AddSingleton<IFileProvider>(
            new PhysicalFileProvider(
                Path.Combine(Directory.GetCurrentDirectory(), "wwwroot")));
builder.Services.AddControllersWithViews();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseMigrationsEndPoint();
}
else
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthentication();


app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");
app.MapRazorPages();

app.Run();

我已经解决了这个问题，我只需要将以下内容添加到 Program.cs 中并使用 localhost:2444/api/{controller name} 调用它

builder.Services.AddRazorPages();
builder.Services.AddControllers();
app.UseEndpoints(endpoints =>
{
    endpoints.MapRazorPages();
    endpoints.MapControllers();
});
