要自定义身份验证ASP.NET Core 3.1,可以按照以下步骤进行:
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;
using System.Linq;
using System.Security.Claims;
using System.Text.Encodings.Web;
using System.Threading.Tasks;
public class CustomAuthenticationHandler : AuthenticationHandler
{
public CustomAuthenticationHandler(IOptionsMonitor options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock) : base(options, logger, encoder, clock) { }
protected override async Task HandleAuthenticateAsync()
{
// 自定义身份验证逻辑
var claims = new[] { new Claim(ClaimTypes.Name, "username") };
var identity = new ClaimsIdentity(claims, Scheme.Name);
var principal = new ClaimsPrincipal(identity);
var ticket = new AuthenticationTicket(principal, Scheme.Name);
return await Task.FromResult(AuthenticateResult.Success(ticket));
}
}
services.AddAuthentication("CustomAuthentication")
.AddScheme("CustomAuthentication", null);
[Authorize(AuthenticationSchemes = "CustomAuthentication")]
public IActionResult SecureAction()
{
// 被身份验证保护的操作
return View();
}
这样就可以自定义身份验证ASP.NET Core 3.1了。请注意,以上只是一个示例,你需要根据自己的实际需求来实现自定义身份验证逻辑。
