        {
            var builder = WebApplication.CreateBuilder(args);
            builder.Services.AddSpaStaticFiles(configuration: options => { options.RootPath = "wwwroot"; });
            builder.Services.AddControllers();
            builder.Services.AddCors(options =>
            {
                options.AddPolicy("VueCorsPolicy", cfg =>
                {
                    cfg
                        .AllowAnyHeader()
                        .AllowAnyMethod()
                        .AllowAnyOrigin();
                });
            });
            var app = builder.Build();
            if (!app.Environment.IsDevelopment())
            {
                app.UseHsts();
            }
            app.UseStaticFiles();
            app.UseSpaStaticFiles();
            app.UseRouting();
            app.UseEndpoints(endpoints => endpoints.MapControllers());
            app.UseCors("VueCorsPolicy");
            app.UseSpa(spa =>
            {
                if (app.Environment.IsDevelopment())
                {
                    spa.UseProxyToSpaDevelopmentServer("http://localhost:5173");
                }
            });
            app.Run();
        }
    }
}

• 必须使用app.UseRouting();app.UseEndpoints(endpoints => endpoints.MapControllers());
• app.MapControllers()这里无效
