Google云存储PHP

Question

嗨，当我运行下面的脚本时，我得到一个奇怪的错误。它将返回此错误消息

Parse error: syntax error, unexpected 'new' (T_NEW) in /home/apipetfindr/public_html/sys/v1/google_cloud_storeage_upload.php on line 9

我想知道为什么我的这部分代码不能工作：

private $storage = new StorageClient

我知道我需要将我尝试过的新函数调用为public，而不是private，但没有成功。如果有人能给我指出正确的方向，那就太好了。

<?php
# Includes the autoloader for libraries installed with composer
require '../vendor/autoload.php';
use Google\Cloud\Storage\StorageClient;


class googleupload{

  private $storage = new StorageClient([
      'projectId' => 'xxxxxxxxxx'
  ]);

  private $bucket = $storage->bucket('BUCKET_NAME');

  // Upload a file to the bucket.
  //$bucket->upload(
  //    fopen('/data/file.txt', 'r')
  //);


  public function uploads($_FILE, $uid){
        $obj = new Google_Service_Storage_StorageObject();
        $obj->setName($file_name);

        $resp = $storage->objects->insert(
            "bucketname",
            $obj,
            array('name' => $file_name, 'data' => file_get_contents("300mb-file.zip"), 'uploadType' => 'media')
        );

  }
}
/*
// Download and store an object from the bucket locally.
$object = $bucket->object('file_backup.txt');
$object->downloadToFile('/data/file_backup.txt');
*/
?>
