WebUploader是由Baidu WebFE(FEX)团队开发的一个简单的以HTML5为主，FLASH为辅的现代文件上传组件。
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist wdteam/yii2-webuploader "*"
or add

Once the extension is installed, simply use it in your code by :
<?= \wdteam\webuploader\Webuploader::widget(); ?>```
