Question

我已经完成了谷歌api集成代码以及文件上传到驱动器。我有关于上传文件名的问题是“Untitled”。请查看代码并指导我缺少的内容。

通过https://developers.google.com/drive/api/v3/reference/files/update上的文档，重命名文件，使用新名称向https://www.googleapis.com/drive/v3/files/<fileId>发送PATCH请求，在您的情况下，我想这将是

$postResult = curl_exec ( $ch );
$parsed = json_decode ( $postResult, true );
if (! $parsed || $parsed ['code'] !== 200) {
    throw new \RuntimeException ( 'google api error: ' . $postResult );
}
$id = $parsed ['id']; // ?? wait, is it id or fileId?
curl_setopt_array ( $ch, array (
        CURLOPT_URL => 'https://www.googleapis.com/drive/v3/files/' . urlencode ( $id ),
        CURLOPT_POST => 1,
        CURLOPT_POSTFIELDS => json_encode ( array (
                'name' => basename ( $filename ) 
        ) ),
        CURLOPT_CUSTOMREQUEST => 'PATCH',
        CURLOPT_HTTPHEADER => array (
                'Content-Type : application/json',
                'Authorization: Bearer ' . getAccessToken ( $credentials ) 
        ) 

) );
curl_exec($ch);

ps，使用CURLOPT_POSTFIELDS时不要手动设置Content-Length标题，因为curl会为你做，如果你使用multipart / form-data，你自己设置的长度很可能是甚至是错误的（不关心你的代码，因为你没有使用multipart / form-data，但这是一个学习的好习惯，但要摆脱它。）
