使用 IAM 策略Amazon SDK for PHP版本 3

您通过创建策略向用户授予权限。策略是一个文档，其中列出了用户可以执行的操作以及这些操作会影响的资源。默认情况下会拒绝未显式允许的任何操作或资源。可将策略附加到用户、用户组、用户代入的角色以及资源。

以下示例演示如何：

Amazon SDK for PHPGitHub 上提供了的所有示例代码。

凭证

运行示例代码之前，请配置Amazon凭证，如中所述设置 凭证. 然后导入Amazon SDK for PHP，如中所述基本用法.

创建策略

导入 

require 'vendor/autoload.php';

use Aws\Iam\IamClient; 
use Aws\Exception\AwsException;

示例代码 

$client = new IamClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2010-05-08'
]);

$myManagedPolicy = '{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "logs:CreateLogGroup",
            "Resource": "RESOURCE_ARN"
        },
        {
            "Effect": "Allow",
            "Action": [
            "dynamodb:DeleteItem",
            "dynamodb:GetItem",
            "dynamodb:PutItem",
            "dynamodb:Scan",
            "dynamodb:UpdateItem"
        ],
            "Resource": "RESOURCE_ARN"
        }
    ]
}';

try {
    $result = $client->createPolicy(array(
        // PolicyName is required
        'PolicyName' => 'myDynamoDBPolicy',
        // PolicyDocument is required
        'PolicyDocument' => $myManagedPolicy
    ));
    var_dump($result);
} catch (AwsException $e) {
    // output error message if fails
    error_log($e->getMessage());
}

将策略附加到角色

导入 


require 'vendor/autoload.php';

use Aws\Iam\IamClient; 
use Aws\Exception\AwsException;

示例代码 

$client = new IamClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2010-05-08'
]);

$roleName = 'ROLE_NAME';

$policyName = 'AmazonDynamoDBFullAccess';

$policyArn = 'arn:aws:iam::aws:policy/AmazonDynamoDBFullAccess';

try {
    $attachedRolePolicies = $client->getIterator('ListAttachedRolePolicies', ([
        'RoleName' => $roleName,
    ]));
    if (count($attachedRolePolicies) > 0) {
        foreach ($attachedRolePolicies as $attachedRolePolicy) {
            if ($attachedRolePolicy['PolicyName'] == $policyName) {
                echo $policyName . " is already attached to this role. \n";
                exit();
            }
        }
    }
    $result = $client->attachRolePolicy(array(
        // RoleName is required
        'RoleName' => $roleName,
        // PolicyArn is required
        'PolicyArn' => $policyArn
    ));
    var_dump($result);
} catch (AwsException $e) {
    // output error message if fails
    error_log($e->getMessage());
}

将策略附加到用户

导入 


require 'vendor/autoload.php';

use Aws\Iam\IamClient; 
use Aws\Exception\AwsException;

示例代码 

$client = new IamClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2010-05-08'
]);

$userName = 'USER_NAME';

$policyName = 'AmazonDynamoDBFullAccess';

$policyArn = 'arn:aws:iam::aws:policy/AmazonDynamoDBFullAccess';

try {
    $attachedUserPolicies = $client->getIterator('ListAttachedUserPolicies', ([
        'UserName' => $userName,
    ]));
    if (count($attachedUserPolicies) > 0) {
        foreach ($attachedUserPolicies as $attachedUserPolicy) {
            if ($attachedUserPolicy['PolicyName'] == $policyName) {
                echo $policyName . " is already attached to this role. \n";
                exit();
            }
        }
    }
    $result = $client->attachUserPolicy(array(
        // UserName is required
        'UserName' => $userName,
        // PolicyArn is required
        'PolicyArn' => $policyArn,
    ));
    var_dump($result);
} catch (AwsException $e) {
    // output error message if fails
    error_log($e->getMessage());
}

将策略附加到组

导入 


require 'vendor/autoload.php';

use Aws\Iam\IamClient; 
use Aws\Exception\AwsException;

示例代码 

$client = new IamClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2010-05-08'
]);

try {
    $result = $client->attachGroupPolicy(array(
        // GroupName is required
        'GroupName' => 'string',
        // PolicyArn is required
        'PolicyArn' => 'string',
    ));
    var_dump($result);
} catch (AwsException $e) {
    // output error message if fails
    error_log($e->getMessage());
}

分离用户策略

$client = new IamClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2010-05-08'

try {
    $result = $client->detachUserPolicy(array(
        // UserName is required
        'UserName' => 'string',
        // PolicyArn is required
        'PolicyArn' => 'string',
    ));
    var_dump($result);
