静态资源管理
1.静态资源包定义
<?php
namespace app\assets;
use yii\web\AssetBundle;
/**
* Main application asset bundle.
*
* @author Qiang Xue <qiang.xue@gmail.com>
* @since 2.0
*/
class AppAsset extends AssetBundle
{
public $basePath = '@webroot';
public $baseUrl = '@web';
public $css = [
'css/site.css',
'css/main.css',
'css/red.css',
];
public $js = [
'js/jquery-migrate-1.2.1.js',
'js/bootstrap.min.js',
['js/html5shiv.js','condition'=>'lte IE9','position'=>\yii\web\View::POS_HEAD],
['js/respond.min.js','condition'=>'lte IE9','position'=>\yii\web\View::POS_HEAD],
];
public $depends = [
'yii\web\YiiAsset',
'yii\bootstrap\BootstrapAsset',
];
}
2.使用静态资源包
<?php
/* @var $this \yii\web\View */
/* @var $content string */
use app\widgets\Alert;
use yii\helpers\Html;
use yii\bootstrap\Nav;
use yii\bootstrap\NavBar;
use yii\widgets\Breadcrumbs;
use app\assets\AppAsset;
AppAsset::register($this);
?>
<?php $this->beginPage() ?>
<!DOCTYPE html>
<html lang="<?= Yii::$app->language ?>">
<head>
<meta charset="<?= Yii::$app->charset ?>">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<?= Html::csrfMetaTags() ?>
<title><?= Html::encode($this->title) ?></title>
<?php $this->head() ?>
</head>
<body>
<?php $this->beginBody() ?>
<div class="wrapper">
<?
NavBar::begin(['options'=>[
'class'=>'top-bar animate-dropdown'
]]);
echo Nav::widget([
'options'=>['class'=>'navbar-nav navbar-left'],
'items'=>[
['label'=>'首页','url'=>['/index/index']],
Yii::$app->user->isGuest?'':['label'=>'我的购物车','url'=>'/cart/index'],
Yii::$app->user->isGuest?'':['label'=>'我的订单','url'=>'/order/index']
]
]);
echo Nav::widget([
'options'=>['class'=>'navbar-nav navbar-right'],
'items'=>[
Yii::$app->user->isGuest?['label'=>'注册','url'=>'/register/index']:['label'=>'个人中心','url'=>'user/index'],
Yii::$app->user->isGuest?['label'=>'登录','url'=>'/site/login']:['label'=>'退出','url'=>'/site/logout']
]
]);
NavBar::end();
?>
<?php echo $content;?>
</div><!-- /.wrapper -->
<?php $this->endBody() ?>
</body>
</html>
<?php $this->endPage() ?>
用户认证体系
1.实现认证组件User,实现认证接口\yii\web\IdentityInterface的五个方法。
2.分离前后台认证
- 修改配置文件，组件配置，
'user' => [
'identityClass' => 'app\models\User',
'enableAutoLogin' => true,
'idParam'=>'_user',
'identityCookie'=>['name'=>'_user_identity','httpOnly'=>true],
'loginUrl'=>['site/login']
],
'admin' => [
'class'=>'yii\web\User',
'identityClass' => 'app\models\admin',
'enableAutoLogin' => true,
'idParam'=>'_admin',
'identityCookie'=>['name'=>'_admin_identity','httpOnly'=>true],
'loginUrl'=>['admin/public/login']
],
- AccessControl 过滤器控制认证用户
public $actions=['*'];//需要用规则去验证的方法
public $except=[];//不需要规则去验证的方法
public $mustLogin=['*'];//必须要登录的方法
/**
* 这个装饰器方法可以抽离到公共控制器中，提高重用性
*/
public function behaviors()
{
return [
'access' => [
'class' => AccessControl::class,
'user'=>'amdin',//默认为'user'=>'user',和配置文件中的用户认证组件对应
'only' => ['*'],
'except'=>[],
'rules' => [
[
'allow' => true,
'actions' => $this->mustLogin,
'roles' => ['@'],
],
[
'allow' => false,
'actions' => $this->mustLogin,
'roles' => ['?'],
],
],
],
//控制方法的请求方式
'verbs' => [
'class' => VerbFilter::class,
'actions' => [
'logout' => ['get'],
],
],
];
}
RBAC
1.数据库
- auth_item #存储角色，权限
- auth_item_child #角色权限中间表
- auth_assignment #角色用户中间表
- auth_rule * 规则表
2.rbac存储方式
- 数据库的存储方式
yii\rbac\DbManager
创建表的命令，执行这个命令之前需要先在console.php中配置authManager
'authManager' => [
'class' => 'yii\rbac\DbManager',
'itemTable' => '{{%auth_item}}',
'assignmentTable' => '{{%auth_assignment}}',
'itemChildTable' => '{{%auth_item_child}}',
'ruleTable'=>'{{%auth_rule}}',
],
yii migrate --migrationPath=@yii/rbac/migrations
- 文件存储方式
yii\rbac\PhpManager
@app/rbac
3.rbac相关的操作类 - yii\rbac\Item #角色后者权限的基本类，用字段type来区分
- yii\rbac\Role #Role为代表角色的类
- yii\rbac\Permission #权限类
- yii\rbac\Assignment #用户和角色的关联
- yii\rbac\Rule #角色权限的额外规则
4.Yii2 ActiveRecord 添加额外属性（在将对象输出成json的时候会用到）
1.模型中
/**
* 添加额外的属性
* @return array
*/
public function attributes()
{
$attributes = parent::attributes();
$attributes[] = 'roleText';
return $attributes;
}
2.在输出json之前，将属性设值
/**@var $user \backend\models\User**/
$user= $query->one();
//角色名称
$user->setAttribute('roleText', $user->getRoleText());
