如何獲取當前用戶在Laravel中登錄的時間？

Question

我正在使用Laravel身份驗證 。 如何獲取當前用戶登錄的時間？ 我想計算自當前用戶登錄以來經過的秒數。如果有一種方法可以在不使用事件的情況下實現它，那就太棒了。

這可以通過覆蓋Auth/LoginController的AuthenticatesUsers特性中的一個方法來完成：

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Carbon\Carbon;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    /**
     * The user has been authenticated.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  mixed  $user
     * @return mixed
     */
    protected function authenticated(Request $request, $user)
    {
        $user->authenticated_at = Carbon::now();

        $user->save();

        return redirect()->intended($this->redirectPath());
    }
}

然后識別用戶模型上的日期字段：

...
class User extends Authenticatable
{
    use Notifiable;

    protected $dates = ['authenticated_at'];
...

當然，將其添加到users表的/ a遷移文件中： $table->timestamp('authenticated_at')->nullable();

您可以通過$user->uptime來獲取“正常運行時間”的可能代碼段:(添加到用戶模型）

public function getUptimeAttribute(): int
{
    return Carbon::now()->diffInSeconds($this->getAttribute('authenticated_at'));
}
