class NewsController extends ActiveController { public $modelClass = 'app\models\News'; #定制serializer #public $serializer = 'yii\rest\Serializer'; public $serializer = [ 'class' => 'app\controllers\rest\Serializer', 'collectionEnvelope' => 'items', ]; public function behaviors() { $be = ArrayHelper::merge( parent::behaviors(), [ 'verbFilter' => [ 'class' => VerbFilter::className(), 'actions' => [ 'index' => ['get'], ... ] ], 'authenticator' => [ 'class' => CompositeAuth::className(), 'authMethods' => [ HttpBasicAuth::className(), HttpBearerAuth::className(), QueryParamAuth::className(), ] ], 'contentNegotiator' => [ 'class' => ContentNegotiator::className(), 'formats' => [ 'text/html' => Response::FORMAT_HTML, ] ], 'access' => [ 'class' => AccessControl::className(), 'only' => ['view'], 'rules' => [ [ 'actions' => ['view'], 'allow' => false, 'roles' => ['@'], ], ], ] ], ); return $be; } public function checkAccess() { } }
3. 定制Actions
如果要对 Actions 进行大的改动，建议拷贝一份出来，不要使用原始的 yii\rest\XXXAction命名空间
我这里以要实现对related models进行 CURD 操作为目标进行大的改动
Action
在定制各个action之前， 先看看它们的基类 rest\Action, 主要是一个 findModel的方法
class Action extend \yii\base\Action { public $modelClass; public $findModel; public $checkAccess; public function init() { if($this->modelClass == null) { throw new InvalidConfigException(get_class($this). '::$modelClass must be set'); } } public function findModel($id) { if($this->findModel !== null) { return call_user_func($this->findModel, $id, $this); } $modelClass = $this->modelClass; $keys = $modelClass::primaryKey(); if(count($keys) > 1) { $values = explode(',', $id); if.. } elseif($id !== null) { $model = $modelClass::findOne($id); } if(isset($model)){ return $model; }else { throw new NotFoundHttpException("Object not found: $id"); } } }
view
view 动作不需要改动，因为 model 有 getRelated 的自有机制
class ViewAction extend Action { public function run($id) { $model = $this->findModel($id); if($this->checkAccess) { call_user_func($this->checkAccess, $this->id, $model); } } }
update
public function run($id) { /* @var $model ActiveRecord */ $model = $this->findModel($id); if ($this->checkAccess) { call_user_func($this->checkAccess, $this->id, $model); } $model->scenario = $this->scenario; $model->load(Yii::$app->getRequest()->getBodyParams(), ''); $model->save(); return $model; }
经过改造后，需要满足对关联模型的update动作
public function run($id) { /* @var $model ActiveRecord */ $model = $this->findModel($id); if ($this->checkAccess) { call_user_func($this->checkAccess, $this->id, $model); } $model->scenario = $this->scenario; /* * * x-www-form-urlencoded key=>value * image mmmmmmmm * link nnnnnnnnnn * newsItem[title]=>ttttttttttt , don't use newsItem["title"] * newsItem[body]=>bbbbbbbbbbb * don't use newsItem=>array("title":"tttttt","body":"bbbbbbb") * don't use newsItem=>{"title":"ttttttt","body":"bbbbbbbb"} * */ $newsItem = Yii::$app->getRequest()->getBodyParams()['newsItem']; /* Array ( [title] => ttttttttttt [body] => bbbbbbbbbbb ) */ $model->newsItem->load($newsItem, ''); #$model->newsItem->load(Yii::$app->getRequest()->getBodyParams(), ''); #print_R($model->newsItem);exit; #print_R($model->newsItem);exit; if($model->save()) { $model->load(Yii::$app->getRequest()->getBodyParams(), ''); $model->newsItem->save(); } return $model; }
这里还应该对 newsItem save 失败 的情况进行处理，暂且不处理。
