如何使用php将文件上传到我的谷歌驱动器（即不是最终用户）

Question

I want to use My Google drive for storing my files which users will upload on my website. 我想使用My Google驱动器存储用户将在我的网站上传的文件。 Here is the code what I am using so far. 这是我到目前为止使用的代码。

<!-- this is my index.php-->
<?php
ob_start();
error_reporting(E_ALL);
 ini_set('display_errors', '1');
require("functions.php");
session_start();
header('Content-Type: text/html; charset=utf-8');
$authUrl = getAuthorizationUrl("", "");
?>
<!DOCTYPE html>
<html lang="fi">
<head>
    <title>Google Drive Login and Upload</title>
    <meta charset="UTF-8">
</head>
<body>
<a href=<?php echo "'" . $authUrl . "'" ?>>Authorize</a>
</body>
</html>


<!--This is my fileUpload.php-->
<?php
ob_start();
require_once("functions.php");
session_start();

header('Content-Type: text/html; charset=utf-8');

global $CLIENT_ID, $CLIENT_SECRET, $REDIRECT_URI;
$client = new Google_Client();
$client->setClientId($CLIENT_ID);
$client->setClientSecret($CLIENT_SECRET);
$client->setRedirectUri($REDIRECT_URI);
$client->setScopes('email');

$authUrl = $client->createAuthUrl();    
getCredentials($_GET['code'], $authUrl);

$userName = $_SESSION["userInfo"]["name"];
$userEmail = $_SESSION["userInfo"]["email"];

?>
<!DOCTYPE html>
<html lang="fi">
<head>
    <title>Logged in</title>
    <meta charset="UTF-8">
</head>
<body>

    Hello <?php echo $userName; ?>!
    <br>
    <?php echo $userEmail; ?>

    <br><br><br>

    <form enctype="multipart/form-data" action="formAction.php" method="POST">
        <input type="file" name="file" required>
        <br><br>
        <label for="folderName">Folder name, this either uploads file to an existing folder or creates a new one based on the name</label>
        <br>
        <input type="text" name="folderName" placeholder="My cat Whiskers">

        <br><br>

The Problem I getting is, When a user upload a file it doesn't come to my google drive But it goes to that user's Drive. 我遇到的问题是，当用户上传文件时，它不会来到我的谷歌驱动器但它会转到该用户的驱动器。 :( What I do not want. I want to store that file into my Google drive. :(我不想要的。我想将该文件存储到我的Google驱动器中。

Please help!! 请帮忙！！ Thanks. 谢谢。

Answer 1

If you're successfully uploading files to the user's Google Drive, then congratulations. 如果您已成功将文件上传到用户的Google云端硬盘，那么恭喜您。 You're nearly there. 你快到了。 The only thing you need to change is how you get the access token. 您需要更改的唯一方法是获取访问令牌。 See How do I authorise an app (web or installed) without user intervention? 请参阅如何在没有用户干预的情况下授权应用程序（Web或已安装）？ (canonical ?) （规范？）

Check this out 看一下这个

require_once 'Google/Client.php';
require_once 'Google/Service/Drive.php';

$client = new Google_Client();
// create an app in google and use credential form that app
$client->setClientId('<HERE_YOUR_CLIENT_ID>');
$client->setClientSecret('<HERE_YOUR_CLIENT_SECRET>');
$client->setRedirectUri('<HERE_YOUR_REGISTERED_REDIRECT_URI>');
$client->setScopes(array('https://www.googleapis.com/auth/drive.file'));

session_start();

if (isset($_GET['code']) || (isset($_SESSION['access_token']) && $_SESSION['access_token'])) {
    if (isset($_GET['code'])) {
        $client->authenticate($_GET['code']);
        $_SESSION['access_token'] = $client->getAccessToken();
    } else
        $client->setAccessToken($_SESSION['access_token']);

    $service = new Google_Service_Drive($client);

    //Insert a file
    $file = new Google_Service_Drive_DriveFile();
    $file->setTitle(uniqid().'.jpg');
    $file->setDescription('A test document');
    $file->setMimeType('image/jpeg');

    $data = file_get_contents('a.jpg');

    $createdFile = $service->files->insert($file, array(
          'data' => $data,
          'mimeType' => 'image/jpeg',
          'uploadType' => 'multipart'
    ));

    print_r($createdFile);

} else {
    $authUrl = $client->createAuthUrl();
    header('Location: ' . $authUrl);
    die();
}

Before use this you must have a google app, and the sdk. 在使用之前，您必须拥有Google应用和sdk。

Thanks 谢谢
