推荐答案

完整的演练位于这里 - RazrPHP 。它为您提供了一个逐步安装过程中的一步纲要凭据，并配备了一个易于使用的添加到 PHP SDK的 AWS

The full walkthrough is located HERE - RazrPHP. It gives you a step by step outline of the setup process for credentials and comes with a easy to use add on to the PHP SDK for AWS

• 1 转到AWS，让您的 PUBLIC_KEY 和 PRIVATE_KEY

• 1. Go to AWS and get your PUBLIC_KEY and PRIVATE_KEY

• 在AWS确实有教程，这这里和<一href="http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ec2-key-pairs.html#having-ec2-create-your-key-pair"相对=nofollow>这里

2 打开终端

3 如果您尚未创建您的凭据然而，在终端的新的一页，类型：

3. If you haven't created your credentials yet, in Terminal's fresh page, type in:

nano ~/.aws/credentials

• 的纳米功能页面将打开。你会看到 GNU纳米2.0.6 ... 上方。
• The nano function page will open up. You will see GNU nano 2.0.6... at the top.

4 在纳米页，类型：

[default]
aws_access_key_id = public_key_ABCDEFGHIJKLMNOPQRSTUVWXYZ
aws_secret_access_key = private_key_s0m3_CR42Y_l3tt3rS_i5y0ur53cr3tK3y

• 5。一旦你键入了出去，撞在控制+ X （是......控制，而不是命令）。

• 5. Once you've typed it out, hit CONTROL + X (Yes...Control, not Command).

  • 1 把 AWS_SDK_PHP 在空文件夹

  • 2 在使用SDK文件的顶部（的index.php 或其他），放于：

  • 1. Put the AWS_SDK_PHP in an empty folder

  • 2. At the top of the file using the SDK (index.php or whatever), put in:

  require 'aws/aws-autoloader.php';
  date_default_timezone_set('America/New_York');
  
  use Aws\DynamoDb\DynamoDbClient;
  
  $client = new DynamoDbClient([
      'profile' => 'default',
      'region'  => 'us-east-1',
      'version' => 'latest'
  ]);
  




• 数据类型
  • 取值 =字符串
  • N =号
  • B =二进制
  • Data Types
    • S = String
    • N = Number
    • B = Binary

    
    

    • 的基本方法

    • 描述表

    $result = $client->describeTable(array(
        'TableName' => '[Table_Name]'
    ));
    
    echo $result;
    

  • 将项目

    $response = $client->putItem(array(
        'TableName' => '[Table_Name]', 
        'Item' => array(
            '[Hash_Name]'   => array('S' => '[Hash_Value]'),
            '[Range_Name]'  => array('S' => '[Range_Value]')
        )
    ));
    
    //Echoing the response is only good to check if it was successful. Status: 200 = Success
    echo $response;
    

  • 获取项目

    $response = $client->getItem(array(
        'TableName' => '[Table_Name]',
        'Key' => array(
            '[Hash_Name]'  => array('S' => '[Hash_Value]'),
            '[Range_Name]' => array('S' => '[Range_Value]')
        )
    ));
    
    echo $response;
    

  • 删除项目

    $response = $client->deleteItem(array(
        'TableName' => '[Table_Name]',
        'Key' => array(
            '[Hash_Name]'  => array('S' => '[Hash_Value]'),
            '[Range_Name]' => array('S' => '[Range_Value]')
        )
    ));
    //Echoing the response is only good to check if it was successful. Status: 200 = Success
    echo $response;
    

  • 查询项目

    $response = $client->query(array(
        'TableName' => '[Table_Name]',
        'KeyConditionExpression' => '[Hash_Name] = :v_hash and [Range_Name] = :v_range',
        'ExpressionAttributeValues' =>  array (
            ':v_hash'  => array('S' => '[Hash_Value]'),
            ':v_range' => array('S' => '[Range_Value]')
        )
    ));
    
    echo $response;
    

  希望这有助于。
