aws 自訂 session

為了讓不同的ec2主機上的 php 能讀取相同的 session

之前 google 了一些文章

作法就是把 session 存在  DynamoDB

後來發現官方已有做好的 sdk SessionHandler
https://docs.aws.amazon.com/aws-sdk-php/v3/guide/service/dynamodb-session-handler.html

也找到一篇範例
http://aws.mannem.me/?p=1020

#aws
#php

使用上也算方便
簡單範例:

<?php

ini_set("display_errors", "On"); // 顯示錯誤是否打開( On=開, Off=關 )

error_reporting(E_ALL & ~E_NOTICE);

require 'vendor/autoload.php';

use Aws\Credentials\CredentialProvider;

use Aws\DynamoDb\SessionHandler;

$sdk = new Aws\Sdk([

'region' => 'ap-northeast-1',

'version' => 'latest',

'http' => [

'debug' => true

]

]);

$dynamoDb = $sdk->createDynamoDb();

$sessionHandler = SessionHandler::fromClient($dynamoDb, [

'table_name' => 'sessions'

]);

$sessionHandler->register();

// Start the session

session_start();

// Alter the session data

// $_SESSION['user.name'] = 'xxxx';

// $_SESSION['user.role'] = 'admin';

// Close the session (optional, but recommended)

// session_write_close();

echo "successfully connected";
