AWS SDK for PHP で S3 アクセス

composer が面倒なので pear で入れちゃいました。

動作テスト

<?php

require_once('AWSSDKforPHP/aws.phar');

use Aws\S3\S3Client;

$client = S3Client::factory(array(
    'key'    => '<key>',
    'secret' => '<secret>'
));
$buckets = $client->listBuckets();

foreach ($buckets['Buckets'] as $bucket) {
    $name = $bucket['Name'];
    echo "name:$name\n";
    $iterator = $client->getIterator('ListObjects', array(
                                     'Bucket' => $name));
    foreach ($iterator as $object) {
        $key = $object['Key'];
        echo "  key:$key\n";
    }
}

尚、 と は「アカウント＞セキュリティ認証情報＞アクセス証明書＞アクセスキー」で分かります。

  • 実行

失敗パターン

config を json に分ける方式を試してみたけど、json の中身が謎。とりあえず key と secret を入れたら駄目だった。

{ "key": "<key>", "secret": "<secret>"}
  • さっきとの差分
/*
use Aws\S3\S3Client;
$client = S3Client::factory(array(
    'key'    => 'A',
    'secret' => 'A+O'
));
*/

use Aws\Common\Aws;
$aws = Aws::factory('awsconf.json');
$client = $aws->get('S3');
