Google 驱动器 API 无法写入文件夹

Question

我从 Google 文档中拼凑了这个我正在尝试将测试文件夹写入 Google Drive APP 但我收到此错误：

An error occurred: {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission"
   }
  ],
  "code": 403,
  "message": "Insufficient Permission"
 }
}

网上查了一下好像是作用域的问题？这就是为什么我在下面添加了这么多：

require_once 'vendor/autoload.php';

date_default_timezone_set('Europe/London');

define('APPLICATION_NAME', 'Pauls Google Drive');
define('CREDENTIALS_PATH', '~/.credentials/drive-php-quickstart.json');
define('CLIENT_SECRET_PATH', __DIR__ . '/client_secret_paul.json');
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/drive-php-quickstart.json
define('SCOPES', implode(' ', array(
        Google_Service_Drive::DRIVE,
        Google_Service_Drive::DRIVE_FILE,
        Google_Service_Drive::DRIVE_APPDATA,
        Google_Service_Drive::DRIVE_READONLY,
        Google_Service_Drive::DRIVE_METADATA,
        Google_Service_Drive::DRIVE_METADATA_READONLY
    )
));

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient() {
    $client = new Google_Client();
    $client->setApplicationName(APPLICATION_NAME);
    $client->setScopes(SCOPES);
    $client->setAuthConfig(CLIENT_SECRET_PATH);
    $client->setAccessType('offline');

    // Load previously authorized credentials from a file.
    $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);
    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } else {
        // Request authorization from the user.
        $authUrl = $client->createAuthUrl();
        printf("Open the following link in your browser:\n%s\n", $authUrl);
        print 'Enter verification code: ';
        $authCode = trim(fgets(STDIN));

        // Exchange authorization code for an access token.
        $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);

        // Store the credentials to disk.
        if(!file_exists(dirname($credentialsPath))) {
            mkdir(dirname($credentialsPath), 0700, true);
        }
        file_put_contents($credentialsPath, json_encode($accessToken));
        printf("Credentials saved to %s\n", $credentialsPath);
    }
    $client->setAccessToken($accessToken);

    // Refresh the token if it's expired.
    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
    return $client;
}

/**
 * Expands the home directory alias '~' to the full path.
 * @param string $path the path to expand.
 * @return string the expanded path.
 */
function expandHomeDirectory($path) {
    $homeDirectory = getenv('HOME');
    if (empty($homeDirectory)) {
        $homeDirectory = getenv('HOMEDRIVE') . getenv('HOMEPATH');
    }
    return str_replace('~', realpath($homeDirectory), $path);
}

function getFolderExistsCreate($service, $folderName, $folderDesc) {
    // List all user files (and folders) at Drive root
    $files = $service->files->listFiles();
    $found = false;
    // Go through each one to see if there is already a folder with the specified name
    foreach ($files['items'] as $item) {
        if ($item['title'] == $folderName) {
            $found = true;
            return $item['id'];
            break;
        }
    }
    // If not, create one
    if ($found == false) {
        $folder = new Google_Service_Drive_DriveFile();
        //Setup the folder to create
        $folder->setName($folderName);
        if(!empty($folderDesc))
            $folder->setDescription($folderDesc);
        $folder->setMimeType('application/vnd.google-apps.folder');
        //Create the Folder
        try {
            $createdFile = $service->files->create($folder, array(
                'mimeType' => 'application/vnd.google-apps.folder',
            ));
            // Return the created folder's id
            return $createdFile->id;
        } catch (Exception $e) {
            print "An error occurred: " . $e->getMessage();
        }
    }
}


// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Drive($client);

getFolderExistsCreate( $service, 'Test', 'This is a test folder' );

getFolderExistsCreate 是实际创建文件夹的方法，它刚刚超过代码的一半。请帮忙！！ :) 我已经能够 return 驱动器中的文件列表而没有错误，所以我很高兴凭据和连接都正常。

Answer 1

以下确认如何？

再次确认驱动器 API 已启用。
你说你添加了作用域。所以请删除~/.credentials/drive-php-quickstart.json的文件一次。然后，运行您的脚本并再次创建 drive-php-quickstart.json。这样，添加的范围就会反映到访问令牌和刷新令牌中。

如果这些对您没有用，我很抱歉。

Answer 2

"code": 403, "message": "Insufficient Permission"

此错误指向文件夹权限。

为了让您的应用程序与文件夹通信（写入或读取），您必须与服务帐户电子邮件 ID 共享文件夹。

要遵循的步骤要设置文件夹权限：例如， Google Drive API 使用的凭据是服务帐户密钥，（其他选项是 API 密钥，OAuth 密钥），

从 service-account.json 文件复制 'client_email'。

[创建服务帐号时生成，用于设置google驱动认证的文件：$client->setAuthConfig('service-account.json'), client_email 要查找的模式：SERVICE_ACCOUNT_NAME @ PROJECT_IDiam.gserviceaccount.com ]
在google驱动器中，右击选中需要上传文件的文件夹，选择'Share'。添加 client_email 。单击 'Done'。此过程是为 client_email 提供文件夹访问权限。
获取此文件夹的 folderId（rt。单击 - 选择可共享 link - 仅 id）。在文件调用中使用此 folderId 新 Google_Service_Drive_DriveFile(数组( 'name' => $文件名, 'parents' => array($folderId), '$mimeType' => $ftype)
注意上传的文件也匹配 mimeType。

希望对您有所帮助！
