1.composer安装阿里云OSS SDK
composer require aliyuncs/oss-sdk-php
2.控制器里面引用
use OSS\Core\OssException;
use OSS\OssClient;
use OSS\Core\OssUtil;
2.上传代码逻辑
// 接收文件数据
$file = request()->file('img');
// 取出文件名截取后缀
$name = $file->getOriginalName();
$suffix = strchr($name,'.');
// 阿里云配置
$accessKeyId = "LTAI5t88SfZ5yhH4Sgu1u3gt";
$accessKeySecret = "vbLBZWvzazGZvJpPap20ZyKDoBbdq2";
// Endpoint以杭州为例，其它Region请按实际情况填写。
$endpoint = "oss-cn-shanghai.aliyuncs.com";
// 设置存储空间名称。
$bucket= "*";
// 设置文件名称。
//这里是由sha1加密生成文件名 之后连接上文件后缀
$object = sha1(date('YmdHis', time()) . uniqid()) . $suffix;
$url = 'http://test.caotengfei.xyz/'.$object;
