我正在嘗試使用 php 將 google drive jpg 下載到服務(wù)器，以便將其保存為可用的 jpg，例如手動(dòng)下載時(shí)。我可以從 filemeta 獲取 getWebContentLink 并保存擴(kuò)展名為 .jpg 的“a”文件：$filemeta = $this->service->files->get($id,[    "fields"=>"*"]);$filename = public_path().'/test.jpg';$url=$filemeta->getWebContentLink();file_put_contents($filename, fopen($url, 'r'));然而，這不是真正的 jpg，確實(shí)無法使用<img src="/test.jpg" />元素顯示。設(shè)置：public function __construct() {        $this->getClient();        $this->service= new Google_Service_Drive($this->client);    }    /**     * @return Google_Client     * @throws \Google_Exception     */    protected function getClient() {        $client = new Google_Client();        $client->setApplicationName('Google Drive API PHP Quickstart');        //20200521$client->setScopes(Google_Service_Drive::DRIVE_METADATA_READONLY);       $client->setScopes(Google_Service_Drive::DRIVE_READONLY);       // https://www.googleapis.com/auth/drive.readonly        $client->setAuthConfig(base_path().'/apicredentials/google/credentials.json');        $client->setAccessType('offline');        $client->setPrompt('select_account consent');        // Load previously authorized token from a file, if it exists.        // The file token.json stores the user's access and refresh tokens, and is        // created automatically when the authorization flow completes for the first        // time.        $tokenPath = base_path().'/apicredentials/google/token.json';        if (file_exists($tokenPath)) {            $accessToken = json_decode(file_get_contents($tokenPath), true);            $client->setAccessToken($accessToken);        }        // If there is no previous token or it's expired.        if ($client->isAccessTokenExpired()) {            // Refresh the token if possible, else fetch a new one.            if ($client->getRefreshToken()) {                $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());            }                 }            }
