因此应将其存储为具有公共访问权限的驱动器.我创建了以下代码.它工作正常我不希望用户输入任何内容.

$client->setAccessToken($_SESSION['accessToken']);
    $service = new Google_DriveService($client);
    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    $file = new Google_DriveFile();
    foreach ($files as $file_name) {
        $file_path = 'files/'.$file_name;
        $mime_type = finfo_file($finfo,$file_path);
        $file->setTitle($file_name);
        $file->setDescription('This is a '.$mime_type.' document');
        $file->setMimeType($mime_type);
        $service->files->insert(
            $file,array(
                'data' => file_get_contents($file_path),'mimeType' => $mime_type
            )
        );
    }
    finfo_close($finfo);

我想使用cURL或使用API​​从Azure URL上传.邮件发送时,它会同时自动上传到驱动器.

问题更新

我有功能发送邮件这是完美的工作.我想将一个附件存储到谷歌驱动器并检索该路径到数据库的路径存储.

这一切都将基于API,无需用户交互.该文件是格式的PDF而不是特定的字节,它根据文件的数据而不同.

问题 ：

当我将文件上传到Drive原始文件名时,重命名为无标题.这是代码.

function uploadFile($credentials,$filename,$targetPath)
{

    global $GAPIS;
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL,$GAPIS . 'upload/drive/v2/files?uploadType=media');

    curl_setopt($ch,CURLOPT_BINARYTRANSFER,1);
    //curl_setopt($ch,CURLOPT_POSTFIELDS,array("title" =>"newfile.txt"));
    curl_setopt($ch,file_get_contents($filename));

    curl_setopt($ch,CURLOPT_POST,1);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch,CURLOPT_HTTPHEADER,array('Content-Type : text/plain','Content-Length:' . filesize($filename),'Authorization: Bearer ' . getAccessToken($credentials))
    );

    $postResult = curl_exec($ch);
    curl_close($ch);

    return json_decode($postResult,true);
}
