我已使用Cookie启用身份验证:
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using WebBasic.Core.Controllers;
namespace WebBasic.Core
{
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services.AddAuthentication().AddCookie(AuthController.AuthControllerAuthId);
services.AddAuthorization(options => { options.AddPolicy("IsFoo", policy => policy.RequireClaim("FooType")); });
}
public void Configure(IApplicationBuilder app, ILoggerFactory loggerfactory)
{
app.UseMvc();
app.UseAuthentication();
}
}
}
...并创建了一个通用视图来测试声明:
using System.Collections.Generic;
using System.Linq;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Mvc;
namespace WebBasic.Core.Controllers
{
[Route("/api/[controller]/[action]")]
public class AuthController : Controller
{
public const string AuthControllerAuthId = "AuthControllerAuthId";
public IActionResult Test()
{
var claims = string.Join(", ", User.Claims.Select(i => i.Type));
return Ok($"{User.Identity.IsAuthenticated}: {claims}");
}
public async Task<IActionResult> AuthFixed()
{
var claims = new List<Claim> {new Claim("FooType", "FooValue", ClaimValueTypes.String)};
var userIdentity = new ClaimsIdentity(claims);
var userPrincipal = new ClaimsPrincipal(userIdentity);
await HttpContext.SignInAsync(AuthControllerAuthId, userPrincipal);
return Ok("ok");
}
public async Task<IActionResult> Logout()
{
await HttpContext.SignOutAsync(AuthControllerAuthId);
return Ok("ok");
}
}
}
当我获得/api/auth/authfixed/
个Cookie集时:
Cache-Control:no-cache
Content-Type:text/plain; charset=utf-8
Date:Tue, 05 Sep 2017 13:57:39 GMT
Expires:-1
Pragma:no-cache
Server:Kestrel
Set-Cookie:.AspNetCore.AuthControllerAuthId=...; path=/; samesite=lax; httponly
...但是当我回到api/auth/test
时,我得到了:
False
即。我没有通过身份验证?身份验证中间件没有拿起我的cookie?为什么不呢?
如果我添加[Authorize]
,我会:
System.InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found.
at Microsoft.AspNetCore.Authentication.AuthenticationService.<ChallengeAsync>d__11.MoveNext()
???为什么我需要明确设置?
我知道,我可以将DefaultChallengeScene,DefaultAuthenticationScheme和DefaultScheme设置为CookieAuthenticationDefaults.AuthenticationScheme
,但实际上的所有内容都设置为字符串'Cookies',但它仍然不起作用。
这里到底发生了什么?
答案 0 :(得分:5)
对于遇到此问题的其他人,诀窍是所有组件都需要引用相同的身份ID。
在我的情况下,我使用AuthControllerAuthId
作为我的自定义身份验证标识符,而不是默认的Cookie
。我需要的是确保auth链的所有部分都使用此值。
添加身份验证时:
services.AddAuthentication(options =>
{
options.DefaultChallengeScheme = AuthController.AuthControllerAuthId;
options.DefaultAuthenticateScheme = AuthController.AuthControllerAuthId;
options.DefaultScheme = AuthController.AuthControllerAuthId;
}).AddCookie(AuthController.AuthControllerAuthId)
构建ClaimsIdentity
:
var userIdentity = new ClaimsIdentity(claims, AuthControllerAuthId);
var userPrincipal = new ClaimsPrincipal(userIdentity);
登录时:
await HttpContext.SignInAsync(AuthControllerAuthId, userPrincipal);
一切都在运作,但在我的情况下,诀窍是查看AuthenticationType
上的User.Identity
并确保在所有步骤中正确设置。
