文件上傳推薦使用前端直傳OSS，不推薦上傳到服務器后轉存。
項目使用composer 安裝阿里云OSS上傳組件
~~~
composer require aliyuncs/oss-sdk-php
~~~
上傳文件代碼示例：
~~~
$ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
$bucket = "tovercq";
$resut = $ossClient->uploadFile(bucket名稱, 'object名稱', '本地文件路徑');
~~~
#### $accessKeyId 從OSS獲得的AccessKeyId
#### $accessKeySecret 從OSS獲得的AccessKeySecret
#### $endpoint 您選定的OSS數據中心訪問域名，例如：oss-cn-hangzhou.aliyuncs.com
請根據自己業務處理返回數據。
