openstack中php sdk php-opencloud怎么用

這篇文章主要介紹了openstack中php sdk php-opencloud怎么用，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

   openstack提供的是rest風格的api接口，其說明文檔見：

http://developer.openstack.org/api-ref-guides/bk-api-ref.pdf，為便于理解和簡化調用，這里使用開源的php sdk——php-opencoud。

1 目錄結構

    vendor

 ---------composer

 ---------guzzle

 ---------psr

 ---------rackspace

               --------------php-opencloud

               ---------------------docs

               ---------------------lib

                                               ---OpenCloud

               ---------------------samples

               ---------------------tests

    composer：提供自動加載的功能

    guzzle：處理http請求

    psr：提供日志功能

    rackspace/php-opencloud/lib/OpenCloud：php封裝庫

    OpenCloud不僅支持openstack的api，還支持Rackspace的api。

2 UML模型圖

  由圖中看到，可以從OpenStack客戶端中根據需要獲取不同的服務對象。計算服務用來管理云主機，通過主機類型、鏡像、密鑰對和網絡等數據就可以創建一臺云主機，而且能夠對云主機做出暫停、恢復、停止、開始和重啟等多種操作，還可以得到基于web vnc的控制臺鏈接。對象存儲服務是以容器的形式來存放數據對象，可以給對象名稱設置路徑前綴來對對象進行分類，組織成類似windows文件夾的結構。

3 示例代碼

3.1 計算服務

<?php
require dirname(__DIR__) . '/vendor/autoload.php';

//5.獲取vnc訪問地址

$objectStoreService = $client->objectStoreService('swift', 'regionOne');
 
//1.創建容器(每個云盤使用者都有一個容器跟其對應)
$containerName = 'testContainer';

    if($bytesQuota)
        printf(",BytesQuota:%.6fM",$bytesQuota / 1024 / 1024);
 
    printf("\n");

//3.容器添加對象

//添加文件
$customHeaders = array('Content-Type' => 'text/plain');
$fileData = fopen('D:/upload_small_object.txt', 'r');

//添加目錄(注意后面的斜杠)
$dirName = 'dir1/';
$object = $container->uploadObject($dirName,'');
//目錄添加文件(文件放到目錄中，必須在文件名前加上目錄，形成類似a/b/c/d/1.txt結構(目錄a/,目錄a/b/,目錄a/b/c/,目錄a/b/c/d/))
$fileData = fopen('D:/upload_small_object.txt', 'r');
$object = $container->uploadObject($dirName . 'upload_small_object.txt', $fileData,$customHeaders);
//目錄下再添加目錄
$dirName = $dirName . 'dir1-1/';
$object = $container->uploadObject($dirName,'');
//二級目錄下再添加文件
$fileData = fopen('D:/upload_small_object.txt', 'r');
$object = $container->uploadObject($dirName . 'upload_small_object.txt', $fileData,$customHeaders);
 
//4.枚舉對象
printf("%s Objects-----------------------------------------------------------\n",$containerName);
//是目錄的最后一個字符是斜杠
$objects = $container->objectList();
foreach ($objects as $object)
{
    printf("Name:%-60s,Size:%15.6fM,LastModified:%s\n",$object->getName(),$object->getContentLength(),$object->getLastModified());
}
 
//5.枚舉目錄下的對象(設定前綴)
printf("%s Objects---------------------------------------------------------------\n",$dirName);
$objects = $container->objectList(array('prefix' => $dirName));
foreach ($objects as $object)
{
    printf("Name:%-60s,Size:%15.6fM,LastModified:%s\n",$object->getName(),$object->getContentLength(),$object->getLastModified());
}
 
//6.下載文件
$object = $container->getObject($dirName . 'upload_small_object.txt');
$objectContent = $object->getContent();
$objectContent->rewind();
$stream = $objectContent->getStream();
file_put_contents('D:/123.txt', $stream);
 
//7.刪除容器(刪除云盤使用者時刪除對應云盤)
$objects = $container->objectList();
//循環刪除每個對象(不支持批刪)
foreach ($objects as $object)
