当我启动ASP。NET Core项目，我收到了一个错误的请求。
我试着在IIS上运行我的应用程序，它工作了，但一些功能也导致了“错误请求”，我不知道原因。
网站正常工作，但现在我突然得到“错误请求”错误。
这是我的startup.cs文件

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)

        });

            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            .AddRoles<IdentityRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>();

    services.Configure<IdentityOptions>(option =>
        {
            option.Password.RequiredLength = 6;
