laravel中的登录页面逻辑

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use IlluminateSupportFacadesAuth;
use IlluminateSupportFacadesRedirect;

class LoginController extends Controller
{
    //登录页面：
    public function index()
    {
        return view('login.index');
    }

    //登录行为：
    public function login()
    {
        //验证：
        $this->validate(
equest(), [
            'email' => 'required|email',
            'password' => 'required|min:5|max:10',
            'is_remember' => 'integer'
        ]);
        //逻辑：
        $user = 
equest(['email', 'password']);
        $is_remember = boolval(
equest('is_remember'));
        if (Auth::attempt($user, $is_remember)) {
            return redirect('/posts');
        }
        //渲染：
        return Redirect::back()->withErrors('邮箱密码不匹配');
    }

    //退出行为：
    public function logout()
    {
        Auth::logout();
        return 
edirect('login');
    }
}
