asp.net core自定义授权过滤器

1.记录点击页面的地址，如果点击页面时未登录，直接跳转到登录页面，登录后直接跳转到自己点击的页面
2.创建授权过滤器

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;
using System.Web;namespace Log4NetTest
{//授权过滤器public class CustomerAuthorizeAttribute : Attribute, IAuthorizationFilter{public void OnAuthorization(AuthorizationFilterContext context){//获取目前地址var controller = context.RouteData.Values["controller"];var action = context.RouteData.Values["action"];//判断是否登录if (!context.HttpContext.User.Identity!.IsAuthenticated){//记录要跳转的页面路径context.Result = newRedirectToActionResult("Login", "WeatherForecast",new { RedirectUrl = HttpUtility.UrlEncode($"/{controller}/{action}") });}}}
}

2.登录接口

[HttpPost]public async Task<IActionResult> Login(string usename, string pwd, string RedirectUrl){var user = await _userManager.FindByNameAsync(usename);if (user != null){var re = await _signInManager.PasswordSignInAsync(user, pwd, false, false);if (re.Succeeded){if (!string.IsNullOrEmpty(RedirectUrl)){//进行页面跳转return Redirect(HttpUtility.HtmlDecode(RedirectUrl));}return Ok();}return Ok();}return Ok();}
