Question

我已经使用您的在线教程创建了一个登录页面。它显示了我通过一些软件包创建登录过程。我忘记了那是什么。

现在，我要执行的操作是，如果用户是有效用户，则将用户名，角色和名称保存在会话变量中。我怎样才能做到这一点？这是从该软件包安装中创建的代码。

控制器代码LoginController.php

<?php
namespace App\Http\Controllers\Auth;

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

class LoginController extends Controller
{
    use AuthenticatesUsers;

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

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

AuthenticatesUsers.php的代码

<?php

namespace Illuminate\Foundation\Auth;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Validation\ValidationException;

trait AuthenticatesUsers
{
    use RedirectsUsers, ThrottlesLogins;

    /**
     * Show the application's login form.
     *
     * @return \Illuminate\Http\Response
     */
    public function showLoginForm()
    {
        return view('auth.login');
    }

    /**
     * Handle a login request to the application.
     *
     * @param  \Illuminate\Http\Request  $request

     *
     * @throws \Illuminate\Validation\ValidationException
     */
    public function login(Request $request)
    {
        $this->validateLogin($request);

        // If the class is using the ThrottlesLogins trait, we can automatically throttle
        // the login attempts for this application. We'll key this by the username and
        // the IP address of the client making these requests into this application.
        if ($this->hasTooManyLoginAttempts($request)) {
            $this->fireLockoutEvent($request);

            return $this->sendLockoutResponse($request);
        }

        if ($this->attemptLogin($request)) {
            return $this->sendLoginResponse($request);
        }

        // If the login attempt was unsuccessful we will increment the number of attempts
        // to login and redirect the user back to the login form. Of course, when this
        // user surpasses their maximum number of attempts they will get locked out.
        $this->incrementLoginAttempts($request);

        return $this->sendFailedLoginResponse($request);
    }

Answer 1

使用Laravel 5，对用户进行身份验证后，您还可以从Auth类（如下所示）中调用登录用户

$user = Auth::user();

现在，通过用户对象，您可以获取用户的名称和角色，因此无需在会话中手动保存它。用户登录后，可以调用上述方法。

此外，我认为这将与上述软件包一起使用，因为LoginController使用AuthenticatedUsers特性。

因此，在任何需要您的用户信息的地方都只需\ Auth :: user（）;

我建议您这样做，因为这是Laravel中的最佳做法，希望对您有所帮助。

Answer 2

从您的代码中，在验证用户身份之后，将其路由到该书。

protected $redirectTo = '/book';

要进行检查，请将此代码块保留在book controller中的任何初始方法中，然后查看结果。

return response()->json(Auth::user());

您将获得attributes中的所有authenticated user。我认为您现在可以继续进行下去。

Answer 3

您可以使用此链接将数据存储到会话中。

通过身份验证的登录名将用户名，角色和名称保存在会话变量中
