ASP.NET Core AuthenticationHandler 依赖注入(inject)

Question

正在关注 this article ，我正在尝试实现自定义 AuthenticationHandler，但我陷入了依赖注入(inject)。

我需要将 IRepository 实例注入(inject)到 AuthenticationHandler 中以提供 dbo 连接(以检查凭据)。

代码:

public class CustomAuthenticationHandler : AuthenticationHandler<CustomAuthenticationOptions>  
{
    // how to inject this?!
    private IRepository repository;

    public CustomAuthenticationHandler(IOptionsMonitor<CustomAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock)
        : base(options, logger, encoder, clock) {
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync()
    {
        // this is just a sample
        if (repository.users.Count(w => w.user_name == Request.Headers["user_name"] && w.password == Request.Headers["password"]) == 1) 
        { 
            return Task.FromResult(
                AuthenticateResult.Success(
                    new AuthenticationTicket(
                        new ClaimsPrincipal(Options.Identity),
                        new AuthenticationProperties(),
                        this.Scheme.Name)));
        }

        return Task.FromResult(
            AuthenticateResult.Failed("...");
        );
    }

你有什么提示吗？

谢谢

只需在构造函数中添加repository依赖，在构造函数体中设置变量

public CustomAuthenticationHandler(
    IOptionsMonitor<CustomAuthenticationOptions> options,
    ILoggerFactory logger,
    UrlEncoder encoder,
    ISystemClock clock,
    IRepository repo)
        : base(options, logger, encoder, clock) {
    repository = repo;
}
