public async Task<IAuthenticationHandler> GetHandlerAsync(HttpContext context, string authenticationScheme) { if (_handlerMap.ContainsKey(authenticationScheme)) { return _handlerMap[authenticationScheme]; } var scheme = await Schemes.GetSchemeAsync(authenticationScheme); if (scheme == null) { return null; } var handler = (context.RequestServices.GetService(scheme.HandlerType) ?? ActivatorUtilities.CreateInstance(context.RequestServices, scheme.HandlerType)) as IAuthenticationHandler; if (handler != null) { await handler.InitializeAsync(scheme, context); _handlerMap[authenticationScheme] = handler; } return handler; }
最后我们在页面上想要获取登录的信息，可以通过 HttpContext.User.Claims 中的签名信息获取。
@using Microsoft.AspNetCore.Authentication <h2>HttpContext.User.Claims</h2> <dl> @foreach (var claim in User.Claims) { <dt>@claim.Type</dt> <dd>@claim.Value</dd> } </dl> <h2>AuthenticationProperties</h2> <dl> @foreach (var prop in (await Context.AuthenticateAsync()).Properties.Items) { <dt>@prop.Key</dt> <dd>@prop.Value</dd> } </dl>
三.最后效果以及源码地址#
