我正在制作一个开源应用程序，用户可以在其中使用PHP SDK将其Facebook相册备份到Google驱动器。我已经完成了Facebook部分，现在却停留在google的书面文档中。所以这是我逐步使用的方式：
用户身份验证：：我所有的请求和回调都在一个PHP文件中进行管理，以寻求类似于API的工作方式。因此，这是处理将文档上传到google的请求的代码块：
<?php
session_start();
require_once __DIR__.'/classes/facebook.class.php';
require_once __DIR__.'/classes/drive.class.php';
$fb = new Facebook();
$google = Drive::getInstance();
$query = $_REQUEST['i'];
switch($query){
case "backup_req":
$agent = $google->getAgent();
if(!isset($_SESSION['google_access_token'])){
$_SESSION['album_temp'] = $_REQUEST['album'];
header("location: ".filter_var($agent->createAuthUrl(), FILTER_SANITIZE_URL));
} else{
$google->uploadAlbum($fb, $_REQUEST['album']);
}
break;
case "google_callback":
$agent = $google->getAgent();
if(!isset($_SESSION['google_access_token'])){
$code = $_GET['code']; // just to keep the code neat.. no need to store in other var!
$res = $google->getAgent()->authenticate($code); // hope this works
$_SESSION['google_access_token'] = $agent->getAccessToken();
}
$google->uploadAlbum($fb, $_SESSION['album_temp']);
break;
}
这是我想做的，如果会话中没有google的访问令牌，我们会将用户重定向到google的登录页面。完成后会重定向到同一文件，但是这次请求google_callback和代码。然后将其存储到会话中，然后继续进行uploadAlbum方法。
注意，我已经回显了服务器的内容，是的，我确实获得了访问令牌和刷新令牌
现在，要上传相册，Drive类中有4种方法（单例）。这是代码：
class Drive{
private static $instance;
private $fileRequest;
private $mimeType;
private $filename;
private $path;
private $client;
private $clientId = "<client-id>";
private $clientSecret = "<client-secret>";
private final function __construct(){
$this->client = new Google_Client();
$this->client->setApplicationName("fb album backup tool");
$this->client->setClientId($this->clientId);
$this->client->setClientSecret($this->clientSecret);
$this->client->setRedirectUri("https://fbrtc.sameer-manek.com/fb_caller.php?i=google_callback");
$this->client->setScopes(array('https://www.googleapis.com/auth/drive.file'));
$this->client->setAccessType("offline");
$this->client->setApprovalPrompt('force');
}
public static function getInstance(){
if(self::$instance == null) {
self::$instance = new Drive();
}
return self::$instance;
}
public function getAgent(){
return $this->client;
}
public function uploadAlbum($fb, $album){
$nodes = $fb->get_photos($album);
$client = new GearmanClient();
$client->addServer();
foreach ($nodes as $node) {
//$client->addTask('init', $node['picture']);
try{
$data = file_get_contents($node['picture']);
$saveto = __DIR__."/../scripts/tmp/".rand().".jpg";
$file = fopen($saveto, "w+");
fwrite($file, $data);
fclose($file);
$this->init($saveto);
echo "uploaded ".$saveto."\n";
} catch(Exception $e) {
return false;
}
}
return true;
//$client->runTasks();
}
public function init($file){
$at = $_SESSION['google_access_token']['access_token'];
$this->client->setAccessToken($at);
$this->fileRequest = $file;
$client = $this->client;
//$client->refreshToken($_SESSION['google_access_token']['refreshToken']);
$tokens = $client->getAccessToken();
$client->setAccessToken($tokens);
$client->setDefer(true);
$this->client->setAccessToken($at);
$this->processFile();
}
public function processFile(){
$fileRequest = $this->fileRequest;
$path_parts = pathinfo($this->fileRequest);
$this->path = $path_parts['dirname'];
$this->fileName = $path_parts['basename'];
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$this->mimeType = finfo_file($finfo, $fileRequest);
finfo_close($finfo);
$this->upload();
}
public function upload(){
$client = $this->client;
$service = new Google_Service_Drive($this->client);
//Insert a file
$file = new Google_Service_Drive_DriveFile();
$file->setName($this->fileName.'.jpg');
$file->setDescription('A test document');
$file->setMimeType('image/jpeg');
$data = file_get_contents($this->fileRequest);
$createdFile = $service->files->create($file, array(
'data' => $data,
'mimeType' => 'image/jpeg',
'uploadType' => 'multipart'
));
}
}
uploadAlbum()方法正在从请求的相册中获取图像。
init()方法正在准备对象以上传该图像（此处，我们为对象使用分配访问令牌）
processFile()方法正在获取和存储有关图像的信息。
upload()方法实际上是将图像上传到用户的Google驱动器。
执行此操作后，没有生成任何异常，也没有生成任何错误，但是当我进行交叉检查时，图像没有上载到驱动器。
我无法指出问题所在，请帮助我解决此错误。谢谢。
[EDIT]我var_dump $createdFile的内容，并在屏幕上以下内容转储：
