文件上传推荐使用前端直传OSS，不推荐上传到服务器后转存。
项目使用composer 安装阿里云OSS上传组件
~~~
composer require aliyuncs/oss-sdk-php
~~~
上传文件代码示例：
~~~
$ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
$bucket = "tovercq";
$resut = $ossClient->uploadFile(bucket名称, 'object名称', '本地文件路径');
~~~
#### $accessKeyId 从OSS获得的AccessKeyId
#### $accessKeySecret 从OSS获得的AccessKeySecret
#### $endpoint 您选定的OSS数据中心访问域名，例如：oss-cn-hangzhou.aliyuncs.com
请根据自己业务处理返回数据。
