php – Google云端硬盘服务帐户上传的位置信息

此代码基于官方文档提供的示例.当我运行php脚本时,我没有错误,我print_r结果变量.它有多个网址,当我使用我创建的相同帐户访问它时,它说我需要请求权限.当我查看我的Google Developers控制台时,它说它收到了请求并成功运行了它.

但是,该文件不会显示在我的Google云端硬盘中.我不确定在服务帐户上查看这些文件的位置,以及如何将此文件存入我的Google云端硬盘.以下是我的代码.

我在某个地方错过了许可,或者我应该以某种方式将服务帐户连接到普通帐户？

DEFINE("TESTFILE",'testfile-small.txt');
    if (!file_exists(TESTFILE)) {
      $fh = fopen(TESTFILE,'w');
      fseek($fh,1024 * 1024);
      fwrite($fh,"!",1);
      fclose($fh);
    }

// The setup

// Authentication Credentials
$client_id = '<my client id>'; //Client ID
$service_account_name = '<my client email'; //Email Address
$key_file_location = '<path to key>'; //key.p12

// Create the client
$client = new Google_Client();
$client->setApplicationName("IEEE_File_Upload");
$service = new Google_Service_Drive($client);

// Check for token
if (isset($_SESSION['service_token'])) {
  $client->setAccessToken($_SESSION['service_token']);
}

// Get the key
$key = file_get_contents($key_file_location);

// Create the credentials
$cred = new Google_Auth_AssertionCredentials(
    $service_account_name,array('https://www.googleapis.com/auth/drive'),$key
);

// Set the credentials
$client->setAssertionCredentials($cred);

// Something with tokens
if ($client->getAuth()->isAccessTokenExpired()) {
  $client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();

// Actual file stuff

  // Now lets try and send the metadata as well using multipart!
  $file = new Google_Service_Drive_DriveFile();
  $file->setTitle("Hello World!");
  $result = $service->files->insert(
      $file,array(
        'data' => file_get_contents(TESTFILE),'mimeType' => 'application/octet-stream','uploadType' => 'multipart'
      )
  );

echo "<h3>Results Of Call:</h3>";
foreach ($result as $item) {
  echo $item['volumeInfo']['title'],"<br /> n";
