php - AWS PHP SDK 筛选 Aws\Result 对象

Question

我正在使用 AWS SDK PHP V3。如果我运行以下代码

$result = $client->getAccountPasswordPolicy([]);
$result = $result->toArray();

返回结果如下

Array
(
    [PasswordPolicy] => Array
        (
            [MinimumPasswordLength] => 6
            [RequireSymbols] => 
            [RequireNumbers] => 
            [RequireUppercaseCharacters] => 1
            [RequireLowercaseCharacters] => 
            [AllowUsersToChangePassword] => 
            [ExpirePasswords] => 
        )

    [@metadata] => Array
        (
            [statusCode] => 200
            [effectiveUri] => https://iam.amazonaws.com
            [headers] => Array
                (
                    [x-amzn-requestid] => 437f79e9-9ee0-11e7-8a82-47e702eaf8eb
                    [content-type] => text/xml
                    [content-length] => 740
                    [date] => Thu, 21 Sep 2017 15:19:29 GMT
                    [connection] => close
                )

            [transferStats] => Array
                (
                    [http] => Array
                        (
                            [0] => Array
                                (
                                )

                        )

                )

        )

)

如何使用 AWS SDK 仅获取 RequireUppercaseCharacters 或 RequireLowercaseCharacters 的结果，还是必须使用数组函数来过滤数据？

啊..你问的是 JMESPath。你可以通过

实现你想要做的事情

$result = $client->getAccountPasswordPolicy([]);
$data = $result->search('PasswordPolicy.RequireUppercaseCharacters');
