Question

我正在使用Visual Studio Code中的命令dotnet run运行DotNet Core 3.0应用程序。该应用程序成功运行，并在控制台中显示了URL https://localhost:5001/和https://localhost:5000/。当我在浏览器中打开https://localhost:5001/时说：

找不到网址为https://localhost:5001/的网页 HTTP错误404

我运行https://localhost:5000/时说：

该网站无法提供安全的连接。本地主机发送了无效的响应。

我确实运行了命令dotnet dev-certs https --trust。问题出在哪里？

Program.cs：

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：

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

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
        services.AddScoped(typeof(IRepository<>), typeof(Repository<>));

        services.AddDbContext<ExperionContext>(options =>
    options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
    }

    // 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.UseHsts();

        app.UseHttpsRedirection();

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }
}

注意：我稍后添加了app.UseHsts();行以进行实验。没有它也不行。
