我按照文章Use cookie authentication without ASP.NET Core Identity并从2.x/Cookies下载了示例。
在 VS 2017 中运行示例。按照文档和代码（受保护）中的指示打开“联系人”页面，使用简单字符串比较在代码中验证的凭据登录，如果已调试，则登录，这意味着它添加了用户主体及其声明，但重定向回登录页面而不是联系页面。
配置服务：
services.Configure<CookiePolicyOptions>(options =>
{
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddMvc()
.AddRazorPagesOptions(options =>
{
options.Conventions.AuthorizePage("/Contact");
})
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
#region snippet1
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie(options => options.ExpireTimeSpan = new System.TimeSpan(0, 10, 0));
#endregion
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
配置
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler("/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseCookiePolicy();
// Call UseAuthentication before calling UseMVC.
#region snippet2
app.UseAuthentication();
#endregion
app.UseMvc();
验证
#region snippet1
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.Email),
new Claim("FullName", user.FullName),
new Claim(ClaimTypes.Role, "Administrator"),
};
var claimsIdentity = new ClaimsIdentity(
claims, CookieAuthenticationDefaults.AuthenticationScheme, ClaimTypes.Name, ClaimTypes.Role);
var authProperties = new AuthenticationProperties
{
AllowRefresh = true,
// Refreshing the authentication session should be allowed.
ExpiresUtc = DateTimeOffset.UtcNow.AddMinutes(10),
// The time at which the authentication ticket expires. A
// value set here overrides the ExpireTimeSpan option of
// CookieAuthenticationOptions set with AddCookie.
IsPersistent = true,
// Whether the authentication session is persisted across
// multiple requests. Required when setting the
// ExpireTimeSpan option of CookieAuthenticationOptions
// set with AddCookie. Also required when setting
// ExpiresUtc.
//IssuedUtc = <DateTimeOffset>,
// The time at which the authentication ticket was issued.
//RedirectUri = <string>
// The full path or absolute URI to be used as an http
// redirect response value.
};
await HttpContext.SignInAsync(
CookieAuthenticationDefaults.AuthenticationScheme,
new ClaimsPrincipal(claimsIdentity),
authProperties);
#endregion
然后我重定向到联系人页面，但又回到了登录页面。
