使用 AWS SDK for Java 在 Amazon S3 Glacier 中建立文件庫

低階 API 為所有文件庫操作提供了方法，包括建立和刪除文件庫、取得文件庫描述以及取得在特定 AWS 區域 中建立的文件庫清單。以下是使用 AWS SDK for Java 建立文件庫的步驟。

1. 建立 AmazonGlacierClient 類別的執行個體 (用戶端)。

   您需要指定要在其中建立文件庫的 AWS 區域。所有您使用此用戶端執行的操作均會套用到該 AWS 區域。

2. 您可以透過建立 CreateVaultRequest 類別的執行個體來提供請求資訊。

   Amazon S3 Glacier (S3 Glacier) 要求您提供文件庫名稱和帳戶 ID。如果您不提供帳戶 ID，則會使用與您提供來簽署請求之登入資料關聯的帳戶 ID。如需更多詳細資訊，請參閱 將 AWS SDK for Java 與 Amazon S3 Glacier 搭配使用。

3. 以參數形式提供請求物件，以便執行 createVault 方法。

   S3 Glacier 傳回的回應在 CreateVaultResult 物件中是可用的。

下列 Java 程式碼片段描述前述步驟。該程式碼片段會在 us-west-2 區域中建立文件庫。列印的 Location 是文件庫的相對 URI，其中包含帳戶 ID、AWS 區域 和文件庫名稱的。

AmazonGlacierClient client = new AmazonGlacierClient(credentials);
client.setEndpoint("https://glacier.us-west-2.amazonaws.com");

CreateVaultRequest request = new CreateVaultRequest()
    .withVaultName("*** provide vault name ***");
CreateVaultResult result = client.createVault(request);

System.out.println("Created vault successfully: " + result.getLocation());

範例：使用 AWS SDK for Java 建立文件庫

以下 Java 程式碼範例在 us-west-2 區域中建立文件庫 (如需關於 AWS 區域 的詳細資訊，請參閱存取 Amazon S3 Glacier)。此外，程式碼範例擷取文件庫資訊, 列出同一 AWS 區域 中的所有文件庫，然後刪除所建立的文件庫。

如需如何執行下列範例的逐步說明，請參閱 使用 Eclipse 執行 Amazon S3 Glacier 的 Java 範例。
