AWS PHP SDK V3中的Cognito身份插图列表

Question

使用AWS PHP SDK V3，如何在结果分页时如何获取所有记录？我有以下代码：

require_once 'vendor/autoload.php';
$cognitoIdentityClient = new AwsCognitoIdentityCognitoIdentityClient([
    'region' => 'eu-west-1',
    'version' => '2014-06-30',
    'credentials' => [
        'key' => '**************',
        'secret' => '***************',
    ],
]);
$identities = $cognitoIdentityClient->getPaginator('ListIdentities', [
    'IdentityPoolId' => 'eu-west-1:****************************',
]);

看起来应该有效，但会产生错误：

Fatal error: Uncaught UnexpectedValueException: There is no ListIdentities paginator defined for the cognito-identity service. in /path/to/vendor/aws/aws-sdk-php/src/Api/Service.php:363
Stack trace:
#0 /path/to/vendor/aws/aws-sdk-php/src/AwsClientTrait.php(23): AwsApiService->getPaginatorConfig('ListIdentities')
#1 /path/to/report.php(24): AwsAwsClient->getIterator('ListIdentities', Array)
#2 {main}
  thrown in /path/to/vendor/aws/aws-sdk-php/src/Api/Service.php on line 363

存在getPaginator方法，但是文件data/cognito-identity/2014-06-30/paginators-1.json.php是空白的，因此没有实现Paginator。我在响应中看到了NextToken，但不了解无缝加载更多结果的模式（do (...) {} while (...)？）

我这样解决了：

$identities = [];
$i = $cognitoIdentityClient->listIdentities([
    'IdentityPoolId' => IDENTITYPOOLID,
    'MaxResults' => 60,
]);
$identities = array_merge($identities, $i->get('Identities'));
while ($nextToken = $i->get('NextToken')) {
    $i = $cognitoIdentityClient->listIdentities([
        'IdentityPoolId' => IDENTITYPOOLID,
        'MaxResults' => 60,
        'NextToken' => $nextToken,
    ]);
    $identities = array_merge($identities, $i->get('Identities'));
}
