Laravel 用户认证快速指南笔记

1、生成进行身份验证所需的所有路由和视图

composer require laravel/ui
php artisan ui vue --auth

2、安装nodejs来使用npm run dev编译脚手架

npm run dev

3、打开D:\server\www\laravel\blog\routes\web.php查看定义的路由

<?php

use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

// 用户认证快速指南生成的路由
// D:\server\www\laravel\blog\vendor\laravel\ui\src\AuthRouteMethods.php 不知道是不是全局收搜出来的
Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');
<?php

namespace Laravel\Ui;

class AuthRouteMethods
{
    /**
     * Register the typical authentication routes for an application.
     *
     * @param  array  $options
     * @return void
     */
    public function auth()
    {
        return function ($options = []) {
            // Authentication Routes...
            $this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
            $this->post('login', 'Auth\LoginController@login');
            $this->post('logout', 'Auth\LoginController@logout')->name('logout');

            // Registration Routes...
            if ($options['register'] ?? true) {
                $this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
                $this->post('register', 'Auth\RegisterController@register');
            }

            // Password Reset Routes...
            if ($options['reset'] ?? true) {
                $this->resetPassword();
            }

            // Password Confirmation Routes...
            if ($options['confirm'] ??
                class_exists($this->prependGroupNamespace('Auth\ConfirmPasswordController'))) {
                $this->confirmPassword();
            }

            // Email Verification Routes...
            if ($options['verify'] ?? false) {
                $this->emailVerification();
            }
        };
    }

    /**
     * Register the typical reset password routes for an application.
     *
     * @return void
     */
    public function resetPassword()
    {
        return function () {
            $this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
            $this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail')->name('password.email');
            $this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm')->name('password.reset');
            $this->post('password/reset', 'Auth\ResetPasswordController@reset')->name('password.update');
        };
    }

    /**
     * Register the typical confirm password routes for an application.
     *
     * @return void
     */
    public function confirmPassword()
    {
        return function () {
            $this->get('password/confirm', 'Auth\ConfirmPasswordController@showConfirmForm')->name('password.confirm');
            $this->post('password/confirm', 'Auth\ConfirmPasswordController@confirm');
        };
    }

    /**
     * Register the typical email verification routes for an application.
     *
     * @return void
     */
    public function emailVerification()
    {
        return function () {
            $this->get('email/verify', 'Auth\VerificationController@show')->name('verification.notice');
            $this->get('email/verify/{id}/{hash}', 'Auth\VerificationController@verify')->name('verification.verify');
            $this->post('email/resend', 'Auth\VerificationController@resend')->name('verification.resend');
        };
    }
}

4 新建D:\server\www\laravel\blog\app\Http\Controllers\Auth\AuthenticatesUsers.php文件 主要是把D:\server\www\laravel\blog\vendor\laravel\ui\auth-backend\AuthenticatesUsers.php文件里面的内容移植到新建的AuthenticatesUsers里面

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

use Illuminate\Foundation\Auth\RedirectsUsers;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
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');
    }

    /**

     *
     * @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 (method_exists($this, 'hasTooManyLoginAttempts') &&
            $this->hasTooManyLoginAttempts($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);

     */
    protected function validateLogin(Request $request)
    {
        $request->validate([
            $this->username() => 'required|string',
            'password' => 'required|string',
        ]);
    }

    /**
     * Attempt to log the user into the application.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return bool
     */
    protected function attemptLogin(Request $request)
    {
        return $this->guard()->attempt(
            $this->credentials($request), $request->filled('remember')
        );
    }

    protected function sendLoginResponse(Request $request)
    {
        $request->session()->regenerate();

        $this->clearLoginAttempts($request);

        if ($response = $this->authenticated($request, $this->guard()->user())) {
            return $response;
        }

        return $request->wantsJson()
            ? new Response('', 204)

     */
    protected function sendFailedLoginResponse(Request $request)
    {
        throw ValidationException::withMessages([
            $this->username() => [trans('auth.failed')],
        ]);
    }

    /**
     * Get the login username to be used by the controller.
     *
     * @return string
     */
    public function username()
    {
        return 'email';
    }

    /**

        $request->session()->regenerateToken();

        if ($response = $this->loggedOut($request)) {
            return $response;
        }

        return $request->wantsJson()
            ? new Response('', 204)
            : redirect('/');
    }

    /**
     * The user has logged out of the application.
     *
     * @param  \Illuminate\Http\Request  $request

     */
    protected function loggedOut(Request $request)
    {
        //
    }

    /**
     * Get the guard to be used during authentication.
     *
     * @return \Illuminate\Contracts\Auth\StatefulGuard
     */
    protected function guard()
    {
        return Auth::guard();
    }
}

5 修改D:\server\www\laravel\blog\app\Http\Controllers\Auth\LoginController.php文件

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
// 使用当前文件夹下的AuthenticatesUsers
// use Illuminate\Foundation\Auth\AuthenticatesUsers;

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 = RouteServiceProvider::HOME;

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

6、在数据库的users表里面添加一条数据(id,name,email,password)其实就是创建一个用户来操作(保存数据库的密码必须使用bcrypt方法来保存)

echo bcrypt('hu*****25');die;

7、访问http://127.0.0.1:8000/home 跳转到http://127.0.0.1:8000/login 页面输入你的账号和密码
