如何获取当前用户在Laravel中登录的时间？

Question

我正在使用Laravel身份验证 。 如何获取当前用户登录的时间？ 我想计算自当前用户登录以来经过的秒数。如果有一种方法可以在不使用事件的情况下实现它，那就太棒了。

这可以通过覆盖Auth/LoginController的AuthenticatesUsers特性中的一个方法来完成：

<?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());
    }
}

然后识别用户模型上的日期字段：

...
class User extends Authenticatable
{
    use Notifiable;

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

当然，将其添加到users表的/ a迁移文件中： $table->timestamp('authenticated_at')->nullable();

您可以通过$user->uptime来获取“正常运行时间”的可能代码段:(添加到用户模型）

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