1. 使用composer安装阿里云的组件

composer require aliyuncs/oss-sdk-php

安装过后会在根目录/vendor目录下有aliyuncs文件夹

2. 写自己的上传文件类

我们自己项目中的文件，不要全部照抄有些内容是你用不到的。

核心：

$this->client = new OssClient($this->key,$this->secret,$this->endpoint);

$content = file_get_contents($uploadPath . $path);

//同步的OSS的文件名，相对于bucket
$object = str_replace('./','',$uploadPath).$path;

  $this->client->putObject($this->bucket,$object,$content);

核心就是上面的四句，上传文件至OSS
