Google API v3 from PHP

Question

上記のhereのAPIを使用してGoogleドライブからファイルをダウンロードしています。フローでは、ユーザーの認証に合格することができ、以下のコードでファイルを一覧表示することができました。

echo "<br>" . count($results->getFiles()). " File(s) found" ; 
     echo "<hr>"; 
     foreach ($results->getFiles() as $file) { 
      echo "File Name is " . $file->getName() . " And file ID is ". $file->getId() . " Type is ".$file->getMimeType() ."<br><pre>"; 
      print_r($file); 
      echo "</pre><hr>"; 
     } 

、出力が

$fileId = '0B5CWXJTNwALMOEJkdzFvMVVsVFE'; 
     $content = $drive_service->files->get($fileId, array(
      'alt' => 'media')); 
     echo "<pre>"; 
     print_r($content->getHeaders()); 
     foreach ($content->getHeaders() as $name => $values) { 

     header($name . ': ' . implode(', ', $values[0])); 
     } 

ファイルがダウンロードされていない以下のようにダウンロードコードを適用しようと、今

質問：ファイルをダウンロードするにはどうすればよいですか？パウロの回答に基づいて

EDIT

below.Thisは、画像/ PNGのために働いて、アプリケーション/オクテットストリーム、アプリケーション/ PDFの種類、しかしZIP/RARファイルの問題を持っているされて、2つのファイルを作成しました（エラー：このサイトはに到達できない）

として

test.phpを

<?php 
require_once __DIR__ . '/vendor/autoload.php'; 
session_start(); 

$client = new Google_Client(); 
$client->setAuthConfigFile('client_secrets.json'); 
$client->addScope(Google_Service_Drive::DRIVE); 

if (isset($_SESSION['access_token']) && $_SESSION['access_token']) 
{ 
    $client->setAccessToken($_SESSION['access_token']); 
    $drive_service = new Google_Service_Drive($client); 
    $results = $drive_service->files->listFiles(); 
    if (count($results->getFiles()) == 0) 
    { 
     echo "No files found"; 
    } 
    else 
    { 
     echo "<br>" . count($results->getFiles()). " File(s) found" ; 
     echo "<br><table><thead><th>File Name</th><th>File Type</th><th>Download Link</th></thead><tbody>"; 
     foreach ($results->getFiles() as $file) { 
      echo "<tr><td>" . $file->getName() . "</td><td>" . $file->getMimeType() ."</td><td><a href='gdrivedownlaod.php?fileid=". $file->getId() . "&type=" . $file->getMimeType() . "&name=" . $file->getName() . "' target='blank'>Download</a></td></tr>";// ."<br><pre>"; 
      } 
      echo "</tbody></table>"; 
    } 

} 
else 
{ 
    $redirect_uri = 'https://abcd.co/oauth2callback'; 
    echo "Hello, <a href='" . $redirect_uri . "'>Log in with Drive</a>"; 
} 

とgdrivedownlaod.php

Answer 1

$fileName = 'xpto.pdf'; 
$driveService = new Google_Service_Drive($client); 
$content = $driveService->files->get($fileId, array(
    'alt' => 'media')); 

$headers = $content->getHeaders(); 
foreach ($headers as $name => $values) { 
    header($name . ': ' . implode(', ', $values)); 
} 
header('Content-Disposition: attachment; filename="' . $fileName . '"'); 
echo $content->getBody(); 
exit; 

Answer 2

上記のとおり$content->getHeaders()は、HTTPリクエストの対応するヘッダー情報の出力を提供しています。

ファイルコンテンツを取得するには、$content->getResponseBody()が必要です。次に、データをローカルファイルに保存するためにfile_put_contentsを呼び出します。
