我在 Startup.cs 中有以下代码:
public void ConfigureServices(IServiceCollection services)
{
//Other middleware
services.AddAuthentication(options =>
{
options.SignInScheme = "MyAuthenticationScheme";
});
services.AddAuthorization();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
//Other configurations.
app.UseCookieAuthentication(options =>
{
options.AuthenticationScheme = "MyAuthenticationScheme";
options.LoginPath = new PathString("/signin/");
options.AccessDeniedPath = new PathString("/signin/");
options.AutomaticAuthenticate = true;
});
}
然后只是为了测试目的,我有一个登录页面,您只需单击一个按钮,它就会发回自己,在 Controller 中使用此代码。
登录 Controller .cs
public IActionResult Index()
{
return View();
}
[HttpPost]
[AllowAnonymous]
public async Task<IActionResult> Index(SignInViewModel model)
{
List<Claim> claimList = new List<Claim>();
claimList.Add(new Claim("Admin", "true"));
ClaimsIdentity identity = new ClaimsIdentity(claimList);
ClaimsPrincipal principal = new ClaimsPrincipal(identity);
await HttpContext.Authentication.SignInAsync("MyAuthenticationScheme", principal);
return RedirectToAction(nameof(HomeController.Index), "Home");
}
这是 HomeController.cs
[Authorize]
public async Task<IActionResult> Index()
{
return View();
}
我得到 401 未经授权。根据我的理解,
SignInAsync
调用应该对用户进行身份验证,而 [Authorize]
属性应该允许任何经过身份验证的用户。如果我在 HomeController.cs 中做这样的事情:ClaimsPrincipal cp = await HttpContext.Authentication.AuthenticateAsync("MyAuthenticationScheme");
我可以看到
cp
确实包含我之前给出的 Admin
声明。我认为这意味着用户已成功通过身份验证。为什么 [Authorize]
属性不起作用? 最佳答案
我认为您需要在身份的构造函数中指定authscheme,您的代码应该更像这样:
var authProperties = new AuthenticationProperties();
var identity = new ClaimsIdentity("MyAuthenticationScheme");
identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, "1"));
identity.AddClaim(new Claim(ClaimTypes.Name, "Admin"));
var principal = new ClaimsPrincipal(identity);
await HttpContext.Authentication.SignInAsync(
"MyAuthenticationScheme",
claimsPrincipal,
authProperties);
return RedirectToAction(nameof(HomeController.Index), "Home");
关于c# - 在 ASP.NET Core 中使用具有自定义 Cookie 身份验证的授权属性,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/36230164/
