谷歌云存储curl PHP上传

我正在尝试使用Curl php上传文件到谷歌云存储。

define("BASE","https://www.googleapis.com/upload/storage/v1/b/");
$key='XXXXX';
$authheaders = array(
"Authorization: Bearer " .$key,
"Content-Type: image/jpeg"
);
$bucket='gs://storage-8c79a.appspot.com';
$file='1234';
$fileName='1.pdf';
$url=BASE.$bucket.'/o?name=name_of_file.jpg&uploadType=multipart';
$curl = curl_init();
curl_setopt($curl, CURLOPT_POSTFIELDS, $file);
curl_setopt($curl, CURLOPT_HTTPHEADER, $authheaders);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_USERAGENT, "HTTP/1.1.5");
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
// 1 is CURL_SSLVERSION_TLSv1, which is not always defined in PHP.
curl_setopt($curl, CURLOPT_SSLVERSION, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, true);

$response = curl_exec($curl);
echo $response;
