PHP使用service account和google drive api 访问google drive 的范例

 

安装库

composer require google/apiclient

范例quickstart.php

<?php
require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    //$client->setApplicationName('Google Drive API PHP Quickstart');
    $client->setScopes(Google_Service_Drive::DRIVE);
    //サビースアカウントキーの設定
    $client->setAuthConfig('borg-230303-6fb36bebedae.json');
    // delegate domain-wide authority to a service accoun、When you prepare to make authorized API calls, you specify the user to impersonate.
    //サビースアカウントが偽装するユーザのメールアドレス //借用或者模拟G suite中用户对google drive的访问权限
    $client->setSubject("w_gao@cm-group.co.jp");

    return $client;
}

//googleドライブで父フォルダーのIDでフォルダー中のファイル情報を取得
function getFilesInParent($service, $parentId, $containName=""){
    $q = "'".$parentId."' in parents ";
    if (!empty($containName)) {
        $q .= " and name contains '".$containName."'";
    }
    $optParams = array(
        'fields' => 'nextPageToken, files(id, name, parents)'
        ,'includeItemsFromAllDrives' => true
        ,'corpora' => 'drive'
        ,"supportsAllDrives"=>true
        ,"driveId" => "0AOYSqx2jksBQUk9PVA"
        ,'q' => $q
    );
    $results = $service->files->listFiles($optParams);
    return $results->getFiles();
}


//ファイルリストの出力
function printfiels($files) {
    if (count($files) == 0) {
        print "No files found.\n";
    } else {
        print "Files:\n";
        foreach ($files as $file) {
            printf("%s  %s \n", $file->getName(), $file->getId);
        }
    }
}


// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Drive($client);
$files = getFilesInParent($service, "1vmhxCGWnLJTQ-ufMdZ7aja4Am5S_nDYy");
printfiels($files);

 

使用命令行进行测试

php quickstart.php

//此范例的共有方式应该是直接将drive文件共有给service account账户
而上面的范例的共有方式是通过G Suite，并借用G Suite内某个用户对google drive的访问权限
