В настоящее время я пытаюсь написать AuthenticationMiddleware. См. this answer. Приложение строит без ошибок, но когда я исполню dnx web
я получаю следующее сообщение об ошибке:Asp.Net: нет подходящего конструктора для аутентификацииMiddleware
Unable to locate suitable constructor for type 'Namespace.BasicAuthenticationMiddleware'. Ensure the type is concrete and all parameters are accepted by a constructor.
at Microsoft.Extensions.Internal.ActivatorUtilities.CreateInstance(IServiceProvider provider, Type instanceType, Object[] parameters)

at Microsoft.AspNet.Builder.Internal.ApplicationBuilder.Build()
at Microsoft.AspNet.Hosting.Internal.HostingEngine.BuildApplication()
fail: Microsoft.AspNet.Hosting.Internal.HostingEngine[7]
Я уверен, что конструктор подписи я использую не так в некотором роде, но я не смог найти подходящую документацию для этого, поскольку кажется, что есть десятки устаревших.
Это AuthenticationMiddleware:
public class BasicAuthenticationMiddleware : AuthenticationMiddleware<BasicAuthOptions>
{
public BasicAuthenticationMiddleware(
RequestDelegate next,
BasicAuthOptions options,
ILoggerFactory loggerFactory,
IUrlEncoder urlEncoder)
: base(next, options, loggerFactory, urlEncoder) {}
protected override AuthenticationHandler<BasicAuthOptions> CreateHandler()
{
return new BasicAuthenticationHandler();
}
}
BasicAuthOptions:
public class BasicAuthOptions : AuthenticationOptions {
public const string Scheme = "BasicAuth";
public BasicAuthOptions()
{
AuthenticationScheme = Scheme;
AutomaticAuthenticate = true;
}
}
BasicAuthenticationExtensions
public static class BasicAuthenticationExtensions
{
public static void UseBasicAuthentication(this IApplicationBuilder builder) {
builder.UseMiddleware<BasicAuthenticationMiddleware>(new ConfigureOptions<BasicAuthOptions>(o => new BasicAuthOptions()));
}
}
Startup.cs:
public class Startup
{
public Startup(IHostingEnvironment env)
{
// Set up configuration sources.
var builder = new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.AddEnvironmentVariables();
Configuration = builder.Build();
}
public IConfigurationRoot Configuration { get; set; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
services.AddAuthorization(options => {
options.AddPolicy(BasicAuthOptions.Scheme, policy => policy.Requirements.Add(new BasicAuthRequirement()));
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
app.UseIISPlatformHandler();
app.UseStaticFiles();
app.UseBasicAuthentication();
app.UseMvc();
}
// Entry point for the application.
public static void Main(string[] args) => Microsoft.AspNet.Hosting.WebApplication.Run<Startup>(args);
}
Здесь вы бросаете. https://github.com/aspnet/HttpAbstractions/blob/02363da94eee7311e457e136dc45edf9c5ac3494/src/Microsoft.AspNetCore.Http.Abstractions/Extensions/UseMiddlewareExtensions.cs#L75 –
