我正在尝试在WebApp中开发自托管的OW。一切正常,直到我尝试集成Windows(NTLM)身份验证。如果仅激活IntegratedWindowsAuthentication,Windows身份验证工作正常。但我需要一些匿名的请求

我已经发现我必须启用两种身份验证方法:

AuthenticationSchemes.IntegratedWindowsAuthentication | AuthenticationSchemes.Anonymous
但在这种情况下,我得到“此请求的授权已被拒绝”。使用Chrome作为客户端()进行测试

请帮忙

OWIN启动类:

public class Startup
{
    public void Configuration(IAppBuilder appBuilder)
    {
        // Enable Windows & Anonymous Authentification
        HttpListener listener = (HttpListener)appBuilder.Properties["System.Net.HttpListener"];
        listener.AuthenticationSchemes = 
                AuthenticationSchemes.IntegratedWindowsAuthentication | AuthenticationSchemes.Anonymous;

        HttpConfiguration config = new HttpConfiguration();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}"
        );
        appBuilder.UseWebApi(config);
    }
}
主程序:

static void Main()
    {
        string baseAddress = "http://localhost:9009/";

        // Start OWIN host 
        using (WebApp.Start<Startup>(url: baseAddress))
        {
            Console.WriteLine("Server ready");
            Console.ReadLine();
        }
    }
static void Main()
{
字符串基地址=”http://localhost:9009/";
//在主机中启动OWIN
使用(WebApp.Start(url:baseAddress))
{
Console.WriteLine(“服务器就绪”);
Console.ReadLine();
}
}
测试控制器:

using System.Collections.Generic;
using System.Security.Principal;
using System.Web.Http;

namespace SelfhostNTAuth

{
public class TestController : ApiController
{
    [Authorize]
    public IEnumerable<string> Get()
    {
        WindowsPrincipal user = RequestContext.Principal as WindowsPrincipal;

        if (user == null)
        {
            return new string[] { "unauthorized"};
        }
        else
        {
            return new string[] { user.Identity.AuthenticationType, user.Identity.Name };
        }
    }
}
}
使用System.Collections.Generic;
使用System.Security.Principal;
使用System.Web.Http;
名称空间SelfhostNTAuth
{
公共类TestController:ApicController
{
[授权]
公共IEnumerable Get()
{
WindowsPrincipal用户=RequestContext.Principal作为WindowsPrincipal;
if(user==null)
{
返回新字符串[]{“unauthorized”};
}
其他的
{
返回新字符串[]{user.Identity.AuthenticationType,user.Identity.Name};
}
}
}
}

对我有效的方法是使用返回基于某些标准的身份验证方案

// Specify the authentication delegate.
listener.AuthenticationSchemeSelectorDelegate = 
    new AuthenticationSchemeSelector (AuthenticationSchemeForClient);
static AuthenticationSchemes AuthenticationSchemeForClient(HttpListenerRequest request)
{
    Console.WriteLine("Client authentication protocol selection in progress...");
    // Do not authenticate local machine requests.
    if (request.RemoteEndPoint.Address.Equals (IPAddress.Loopback))
    {
        return AuthenticationSchemes.None;
    }
    else
    {
        return AuthenticationSchemes.IntegratedWindowsAuthentication;
    }
}
