博主用的是第三个方法

doesBucketExist($bucket)) {
    $ossClient->createBucket($bucket);
}
// 文件名称
$object = $_FILES['filename']['name'];
// 由本地文件路径加文件名包括后缀组成，例如/users/local/myfile.txt
$filePath = $_FILES['filename']['tmp_name'];
try{
    //上传图片
    $ossClient->uploadFile($bucket, $object, $filePath);
    //文件访问权限，设置为所有人可读
    $acl = "public-read";
    $ossClient->putObjectAcl($bucket, $object, $acl);
    echo "";die;
//删除单个文件
//    $ossClient->deleteObjects($bucket, $object);
    //删除多个文件
//    $objects = ['文件名1','文件名2'];
//    $ossClient->deleteObjects($bucket, $objects);
    
    } catch(OssException $e) {
    printf(__FUNCTION__ . ": FAILED\n");
    printf($e->getMessage() . "\n");
    return;
}
print(__FUNCTION__ . ": OK" . "\n");
