Usage

• Add Upload widget in the view, for example:

<?= Upload::widget(['url'=>'/upload/upload']) ?>

Enter the service processing path in "url";

• Add a upload controller, for example:

<?php
namespace backend\controllers;

use Yii;
use yii\web\Response;
use yii\web\UploadedFile;
use oonne\webuploader\UploadServer;

class UploadController extends \yii\rest\Controller
{
    public function behaviors()
    {
        $behaviors = parent::behaviors();
        $behaviors['contentNegotiator']['formats'] = [
            'application/json' => Response::FORMAT_JSON
        ];
        return $behaviors;
    }

    protected function verbs()
    {
        return [
            'upload' => ['post'],
        ];
    }

    public function actionUpload()
    {
        $fileData = Yii::$app->request->post();
        $file = UploadedFile::getInstanceByName('file');
        $fileRet = UploadServer::uploadFile($file, $fileData, Yii::$app->params['temppath'], Yii::$app->params['filepath']);

        if ($fileRet['ret'] == 0) {
            return [
                'Ret' => 0,
                'Filename' => $fileRet['file_name'],
                'Url' => '$downloadUrl',
                'Callback' => 'location.reload(true)',
            ];
        } else {
            return [
                'Ret' => 1000,
            ];    
        }
    }
}
