[我正在尝试使用php将google驱动器jpg下载到服务器,以便将其保存为可用的jpg,例如在手动下载时。
我可以从filemeta获取getWebContentLink并以扩展名.jpg保存'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'));
但是这不是真正的jpg,实际上无法使用<img src="/test.jpg" />
元素显示。
设置:
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());
} 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);
$client->setAccessToken($accessToken);
// Check to see if there was an error.
if (array_key_exists('error', $accessToken)) {
throw new Exception(join(', ', $accessToken));
}
}
// Save the token to a file.
if (!file_exists(dirname($tokenPath))) {
mkdir(dirname($tokenPath), 0700, true);
}
file_put_contents($tokenPath, json_encode($client->getAccessToken()));
}
$this->client=$client;
}
这个答案怎么样?
为了从外部用webContentLink
检索文件内容,需要使用访问令牌,或者需要公开共享文件。因此,在您的脚本中,我认为创建的文件是登录页面的HTML数据。
那么以下解决方法如何?
[使用访问令牌通过webContentLink
下载文件内容。
首先,在Google云端硬盘上公开共享文件。然后,使用当前脚本下载文件内容。
使用Drive API直接下载文件内容。在这种情况下,修改后的脚本如下。如果您使用https://www.googleapis.com/auth/drive.metadata.readonly
作为示波器,请修改为https://www.googleapis.com/auth/drive.readonly
。
$content = $this->service->files->get($id, array("alt" => "media"));
$filename = public_path().'/test.jpg';
file_put_contents($filename, $content->getBody());
