How to use Json for dataProvider Yii2 - json

Question

Hot to use json for dataProvider for display data in Gridview Yii2?
Here is my Controller (Generate Code from Yii2 generator) code:
<?php
namespace app\controllers;
use Yii;
use app\models\Users;
use app\models\UsersSearch;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
/**
* UsersController implements the CRUD actions for Users model.
*/
class UsersController extends Controller
{
/**
* #inheritdoc
*/
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['POST'],
],
],
];
}
/**
* Lists all Users models.
* #return mixed
*/
public function actionIndex()
{
$searchModel = new UsersSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
/**
* Displays a single Users model.
* #param integer $id
* #return mixed
*/
public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),
]);
}
/**
* Creates a new Users model.
* If creation is successful, the browser will be redirected to the 'view' page.
* #return mixed
*/
public function actionCreate()
{
$model = new Users();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
/**
* Updates an existing Users model.
* If update is successful, the browser will be redirected to the 'view' page.
* #param integer $id
* #return mixed
*/
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
/**
* Deletes an existing Users model.
* If deletion is successful, the browser will be redirected to the 'index' page.
* #param integer $id
* #return mixed
*/
public function actionDelete($id)
{
$this->findModel($id)->delete();
return $this->redirect(['index']);
}
/**
* Finds the Users model based on its primary key value.
* If the model is not found, a 404 HTTP exception will be thrown.
* #param integer $id
* #return Users the loaded model
* #throws NotFoundHttpException if the model cannot be found
*/
protected function findModel($id)
{
if (($model = Users::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
}
And my gridview in index is like this:
<?php
use yii\helpers\Html;
use kartik\grid\GridView;
use yii\widgets\ActiveForm;
use yii\widgets\Pjax;
use yii\web\JsExpression;
/* #var $this yii\web\View */
/* #var $searchModel app\models\SalesOrderSearch */
/* #var $dataProvider yii\data\ActiveDataProvider */
?>
<div class="start-stock-index">
<div class="form-group">
<?= Html::a('Create Customer', ['create'], ['class' => 'btn btn-success']) ?>
</div>
<?php Pjax::begin(); ?>
<?= GridView::widget([
'dataProvider'=>$dataProvider,
'filterModel'=>$searchModel,
'showPageSummary'=>true,
'pjax'=>true,
'striped'=>true,
'hover'=>true,
'responsiveWrap' => false,
'panel'=>['type'=>'primary', 'heading'=>$partner_name],
'columns'=>[
[
'attribute' => 'cust_name',
'value' => 'cust_name',
'label' => 'Name',
'contentOptions' =>
['style'=>'max-width: 100px; font-size: 12px;overflow: auto; word-wrap: break-word;'],
],
[
'attribute' => 'phone_number',
'value' => 'phone_number',
'label' => 'Phone Number',
'contentOptions' =>
['style'=>'max-width: 100px; font-size: 12px;overflow: auto; word-wrap: break-word;'],
],
[
'attribute' => 'age_type',
'value' => 'ageType.age_name',
'label' => 'Age Category',
'contentOptions' =>
['style'=>'max-width: 100px; font-size: 12px;overflow: auto; word-wrap: break-word;'],
],
['class' => 'kartik\grid\ActionColumn','template' => '{update} {delete}',],
],
]); ?>
<?php Pjax::end(); ?>
</div>
<?php
$script = <<< JS
JS;
$this->registerJs($script);
?>
What I want is show data from json so that it can be restful page. Thanks.

If you JSON structure is right for an arrayDataProvider
You could conver the JSON data in associative array the use the arrayDataprovider
you can use helper as http://www.yiiframework.com/doc-2.0/yii-helpers-json.html
http://www.yiiframework.com/doc-2.0/yii-helpers-basejson.html#decode()-detail
Json::decode($yourJSON);
