?? ???? ?? ??? ??? ??? ???? ???? ???. Laravel?? ???? "make:model" ??? ???? ? ??? ??? ? ????. ???? ?? ??? ?????.

php artisan make:model User -m

? ??? app ????? User ??? ???? ??????? users? ?????. ???. User ????? ???? ???? ?? ??? ???? ???. Laravel ?????? ??? guard ???? ??? ? ?? ??? ??? ?? ??? ?????: app目錄下生成一個User模型，并且在數(shù)據(jù)庫生成一個users表。在User模型中，我們需要指定用戶使用的認(rèn)證方式。Laravel框架提供了多種用戶認(rèn)證方式，我們可以在模型中的guard屬性中進(jìn)行設(shè)置：

protected $guard = 'web';

創(chuàng)建好用戶模型之后，我們需要再創(chuàng)建一個用于展示用戶注冊頁面的控制器，我們使用以下命令來創(chuàng)建該控制器：

php artisan make:controller AuthRegisterController --resource

運行完這個命令之后，Laravel框架將會在appHttpControllersAuth目錄下創(chuàng)建一個名為RegisterController.php的文件。在該控制器中，我們需要實現(xiàn)以下方法：

use AppUser;
use IlluminateFoundationAuthRegistersUsers;
public function register(Request $request)
{
    $this->validator($request->all())->validate();

    event(new Registered($user = $this->create($request->all())));

    $this->guard()->login($user);

    return redirect($this->redirectTo);
}

// 驗證用戶輸入的數(shù)據(jù)
protected function validator(array $data)
{
    return Validator::make($data, [
        'name' => ['required', 'string', 'max:255'],
        'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
        'password' => ['required', 'string', 'min:8', 'confirmed'],
    ]);
}

// 保存注冊用戶信息到數(shù)據(jù)庫
protected function create(array $data)
{
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => Hash::make($data['password']),
    ]);
}

接下來，我們需要在routes/web.php中添加該控制器的路由：

Route::get('register', 'AuthRegisterController@showRegistrationForm')->name('register');
Route::post('register', 'AuthRegisterController@register');

在前臺頁面上，我們使用以下表單來收集用戶數(shù)據(jù)：

<form method="POST" action="{{ route('register') }}">
    @csrf
    <div>
        <label for="name">用戶名</label>
        <input id="name" type="text" name="name" value="{{ old('name') }}" required autofocus>
    </div>

    <div>
        <label for="email">郵箱</label>
        <input id="email" type="email" name="email" value="{{ old('email') }}" required>
    </div>

    <div>
        <label for="password">密碼</label>
        <input id="password" type="password" name="password" required>
    </div>

    <div>
        <label for="password-confirm">確認(rèn)密碼</label>
        <input id="password-confirm" type="password" name="password_confirmation" required>
    </div>

    <div>
        <button type="submit">注冊</button>
    </div>
</form>

然后我們就成功地創(chuàng)建了用戶注冊流程。

2. 用戶登錄流程

Laravel提供了非?？旖莸挠脩舻卿浄椒ǎ覀兛梢允褂迷摲椒▉磉M(jìn)行用戶登錄。在routes/web.php中添加以下路由：

Route::get('login', 'AuthLoginController@showLoginForm')->name('login');
Route::post('login', 'AuthLoginController@login');
Route::post('logout', 'AuthLoginController@logout')->name('logout');

然后創(chuàng)建一個與User模型對應(yīng)的LoginController控制器。在控制器中，我們需要實現(xiàn)以下方法：

use IlluminateFoundationAuthAuthenticatesUsers;
public function login(Request $request)
{
    $this->validateLogin($request);

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

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

// 認(rèn)證用戶名和密碼
protected function attemptLogin(Request $request)
{
    return $this->guard()->attempt(
        $this->credentials($request), $request->filled('remember')
    );
}

// 獲取用戶名和密碼
protected function credentials(Request $request)
{
    return $request->only($this->username(), 'password');
}

public function username()
{
    return 'email';
}

// 用戶退出登錄方法
public function logout(Request $request)
{
    $this->guard()->logout();

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

    return redirect('/');
}

接著，我們需要創(chuàng)建一個用戶登錄視圖。在視圖中，我們使用以下表單來接收用戶數(shù)據(jù)：

<form method="POST" action="{{ route('login') }}">
    @csrf
    <div>
        <label for="email">郵箱</label>
        <input id="email" type="email" name="email" value="{{ old('email') }}" required autofocus>
    </div>

    <div>
        <label for="password">密碼</label>
        <input id="password" type="password" name="password" required>
    </div>

    <div>
        <input type="checkbox" name="remember" id="remember" {{ old('remember') ? 'checked' : '' }}>
        <label for="remember">記住我</label>
    </div>

    <div>
        <button type="submit">登錄</button>
    </div>
</form>

在創(chuàng)建好以上視圖和控制器之后，我們就實現(xiàn)了Laravel框架的用戶登錄和注冊流程。需要注意的事項是用戶登錄成功之后，需要將用戶信息存入session中，以便于后續(xù)功能的調(diào)用。在控制器的第二個方法中，我們可以利用Laravel框架提供的attemptLoginrrreee
