调用方法:

//use 或者 require 图片上传服务层
use App\Common\Service\Upload AS UploadService;

    /**
     * 上传base64
     * @return mixed
     * @throws \App\Exceptions\ApiException
     */
    public function base64()
    {
        $data = UploadService::saveBase64Image($this->param['thumb']);
        if(!empty($data['url'])){
            $this->res = env('APP_URL').$data['url'];
            return $this->doResponseReturn($this->res, '上传成功');
        }
    }
