AWS IAM for PHP

PHP on AWS

Amazon Web services have N number of services, one among them is Aws Identity and Access Management(IAM). IAM allows you to securely access the AWS services.

Using IAM you can control who can use your AWS service and what resources they can use. With IAM, you can create and manage AWS users and groups, and use permissions to allow and deny their access to AWS resources.

We can integrate IAM with many platforms like NodeJS, .NET, Java, etc., Here we can see how to use AWS IAM with the PHP platform.

require '/path/to/aws-autoloader.php';

<?php
$body  = array(‘type’ => ‘search’, ‘keyword’ => ‘phones’);
$credentials = new Aws\Credentials\Credentials(‘access_key’, ‘secret_key’);
//From https://github.com/aws/aws-sdk-php/issues/671#issuecomment-120666137
// Prepare a CloudSearchDomain request
$headers = array('x-api-key' => 'api_key, 'Content-Type => application/x-www-form-urlencoded');
$request = new GuzzleHttp\Psr7\Request('POST', 'https://knackforge.com/post-endpoint, ['Content-Type' => 'application/x-www-form-urlencoded'],  http_build_query($body, null, '&'));
// Construct a request signer
$signer = new Aws\Signature\SignatureV4('execute-api', 'us-west-2');
// Sign the request
$request = $signer->signRequest($request, $credentials);
// Send the request
$headers = array('Content-Type => application/x-www-form-urlencoded');
$client = new \GuzzleHttp\Client([ 'headers' => $headers]);
$response = $client->send($request);
$result = $response->getBody();
