如何使用Google Drive API v3列出根目录中的文件/目录？

Question

我正在开发一个网站项目。我已经在Google Developers Console上创建了一个应用程序，并在我的服务器上安装了Google SDK。授权完成，离线访问完成，列出所有文件/目录完成，创建文件完成。

现在我想列出位于根目录中的文件/目录。我的意思是只列出那些不是所有子目录的文件/目录。

以下是代码示例：

    // $client is a Google_Client object
    $service = new Google_Service_Drive($client);
    // Print the names and IDs for up to 10 files.
    $optParams = array(
        'pageSize' => 10,
        'fields' => "nextPageToken, files(contentHints/thumbnail,fileExtension,iconLink,id,name,size,thumbnailLink,webContentLink,webViewLink,mimeType,parents)",
        'q' => "trashed=false"
    );
    $results = $service->files->listFiles($optParams);

    if (count($results->getFiles()) == 0) {
        print "No files found.\n";
    } else {

        print "Files:\n";
        foreach ($results->getFiles() as $file) {
            echo "Dosya Adı: ".$file->getName()."<br>";
            echo "Dosya Id: ".$file->getId()."<br>";
            echo "Tip: ".$file->getMimeType()."<br>";
            echo "Dosya Link: ".$file->getWebContentLink()."<br>";
            echo "Dosya Link: ".$file->getWebViewLink()."<br>";
        }
    }

这段代码列出了所有文件/目录（不在垃圾箱中）。我在 q 中添加了 "'root' in parents"，但它没有给出任何结果。在文档中没有找到有用的信息。

以下是输出内容：

请同时提供您代码的输出结果。 - Jujhar Singh

Answer 1

您可以使用“root”作为根目录ID的别名：

$driveService->files->listFiles([
    // 'q' => '"'.MAIN_FOLDER_ID.'" in parents', // optionnal
    'q' => '"root" in parents', // optionnal
    'pageSize' => 100, // 1 to 1000
    'fields' => 'nextPageToken, files(id, name, mimeType, parents)'
]);

Answer 2

我终于找到了解决方案。

// $client is a Google_Client object
function rootFolderId($client) {
    $service = new Google_Service_Drive($client);

    $results = $service->files->get('root');
    return $results->getId();
}

请问您能否在这里添加一个完整的解决方案？您是如何使用$optParams中的root id的？ - Bjørson Bjørson
