直接上程式碼

1、配置

startup.cs 中

public void ConfigureServices(IServiceCollection services)
{
    // 新增 Cook 服務
    services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(options =>
    {
        options.LoginPath = "/Account/LogIn";
        options.LogoutPath = "/Account/LogOff"
 
;
    });

    services.AddMvc();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    ......
    // 使用Cook的中介軟體
    app.UseAuthentication();
    ......
}

2、登入

public IActionResult Login(){
    var user = new ClaimsPrincipal(
    new ClaimsIdentity(new
 
[]
    { 
        new Claim(ClaimTypes.Name, username),
    },
    CookieAuthenticationDefaults.AuthenticationScheme));
    await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, user, new Microsoft.AspNetCore.Authentication.AuthenticationProperties
    {
        IsPersistent = true
 
,
        ExpiresUtc = DateTimeOffset.Now.Add(TimeSpan.FromDays(7)) // 有效時間
    });
    return view();
}

3、退出登入

public async Task<IActionResult> Logout()
{
    await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
    return RedirectToAction("Login", "Account");
}
