我遵循https://docs.microsoft.com/en-us/aspnet/core/tutorials/getting-started-with-swashbuckle?view=aspnetcore-3.1&tabs=visual-studio的指南。这是我的配置

using foo.Areas.Identity;
using foo.Controllers;
using foo.Data;
using Demo.Blazor;
using DevExpress.Blazor.DocumentMetadata;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Components.Authorization;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Options;
using System.Globalization;
using System.Net.Http;
using Microsoft.OpenApi.Models;
using System;

namespace foo
{

    public class Startup
    {

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("vi-VN");
            services.AddServerSideBlazor().AddCircuitOptions(options => { options.DetailedErrors = true; });
            services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
            services.AddDefaultIdentity<IdentityUser>().AddRoles<IdentityRole>().AddEntityFrameworkStores<ApplicationDbContext>();          
            services.AddRazorPages().AddJsonOptions(options => options.JsonSerializerOptions.PropertyNamingPolicy = null);
            services.AddRazorPages().AddRazorPagesOptions(options =>
            {
                //options.Conventions.AuthorizePage("/currencies");
                //options.Conventions.AuthorizeFolder("/accounts");  
            });
            services.AddServerSideBlazor();
            services.AddScoped<AuthenticationStateProvider, RevalidatingIdentityAuthenticationStateProvider<IdentityUser>>();
            services.AddSingleton<WeatherForecastService>();
            services.AddDocumentMetadata((serviceProvider, registrator) =>
            {
                DemoConfiguration config = serviceProvider.GetService<IOptions<DemoConfiguration>>().Value;
                config.RegisterPagesMetadata(registrator);
            });
            services.AddMvc();
            services.AddHealthChecks();
            services.AddHttpClient();
            services.AddScoped<HttpClient>((sp) => {
                var httpClient = sp.GetService<IHttpClientFactory>().CreateClient();
                httpClient.DefaultRequestHeaders.Add("Accept", "application/json");
                return httpClient;
            });
            services.AddDevExpressBlazor();
            services.AddControllers();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
            });
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            // Enable middleware to serve generated Swagger as a JSON endpoint.
            app.UseSwagger();

            // Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.),
            // specifying the Swagger JSON endpoint.
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
            });

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();           
            app.UseRouting();
            app.UseAuthentication();
            //app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                endpoints.MapRazorPages();
                endpoints.MapBlazorHub();
                endpoints.MapFallbackToPage("/_Host");
                endpoints.MapHealthChecks("/health");
            });
        }
    }

}

我发现错误:

无法加载API定义。

应该是这样

        app.UseSwaggerUI(c =>
       {
           c.SwaggerEndpoint("v1/swagger.json", "My API V1");
       });
