Amazon web services 使用sdk for php访问dynamodb

当我尝试运行此代码时，它会给出一个错误，定义为：

致命错误：未捕获异常“Aws\DynamoDb\exception\dynamodbeexception”，消息“在“”上执行“GetItem”时出错”；AWS HTTP错误：cURL错误60:SSL证书问题：无法获取C:\wamp\www\practice\vendor\AWS\AWS sdk php\src\WrappedHttpHandler.php第159行中的本地颁发者证书（请参阅）

require "config.php";
require __DIR__ . '/vendor/autoload.php';
$sdk = new Aws\Sdk([
    'region'   => 'us-east-1',
    'version'  => 'latest',
    'credentials' => array(
        'key' => $global_access_key,
        'secret'  => $global_secret_key,
      ),
]);

$dynamodb = $sdk->createDynamoDb();

$response = $dynamodb->getItem([
    'TableName' => $global_table_name,
'Key' => [
    'userid' => [ 'N' => '1' ]
    ]
]);

var_dump($response);
die;

从读取文档

<>得到了答案，而不是禁用SSL验证，这可能导致中间人攻击。下面的解决方案将更加安全和合适

从下载最新的证书文件

将其保存在代码可访问的路径中。（例如：-C:\nginx\cert\cacert.pem）

根据您使用的aws sdk php的版本，请按如下所示修改代码

版本2.X：-

$sdk = new Aws\Sdk([
'region'   => 'us-east-1',
'version'  => 'latest',
'credentials' => array(
    'key' => $global_access_key,
    'secret'  => $global_secret_key,
  ),
'signature_version' => 'v4',
'http'    => [
    'verify' => false
]
]);

3.X版：-

$aws = Aws\Common\Aws::factory(array(
 'region' => 'us-west-2',
 'key' => '****',
 'secret' => '****',
 'ssl.certificate_authority' => 'C:\nginx\cert\cert.pem'
));

参考文献：-

$client = new DynamoDbClient([
    'region'  => 'us-west-2',
    'version' => 'latest',
    'http'    => [
        'verify' => 'C:\nginx\cert\cert.pem'
    ]
]);
