使用单个操作上传档案 适用于 Java 的 Amazon SDK

适用于 Java 的 Amazon SDK APIs 提供的高级版本和低级版本都提供了一种上传档案的方法。

使用的高级别 API 上传档案 适用于 Java 的 Amazon SDK

该高级 API 的 ArchiveTransferManager 类提供了您可以用来将档案上传到文件库的 upload 方法。

示例：使用的高级别 API 上传档案 适用于 Java 的 Amazon SDK

以下 Java 代码示例将档案上传到美国西部（俄勒冈州）区域 (us-west-2) 中的文件库 (examplevault)。有关支持的 Amazon 区域和终端节点的列表，请参阅访问亚马逊 Glacier。

有关如何运行此示例的 step-by-step说明，请参阅使用 Eclipse 为亚马逊 Glacier 运行 Java 示例。您需要更新目标上传文件库名称和待上传文件名称旁显示的代码。

import java.io.File;
import java.io.IOException;
import java.util.Date;

import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.services.glacier.AmazonGlacierClient;
import com.amazonaws.services.glacier.transfer.ArchiveTransferManager;
import com.amazonaws.services.glacier.transfer.UploadResult;


public class ArchiveUploadHighLevel {
    public static String vaultName = "*** provide vault name ***";
    public static String archiveToUpload = "*** provide name of file to upload ***";
    
    public static AmazonGlacierClient client;
    
    public static void main(String[] args) throws IOException {
        
        
    	ProfileCredentialsProvider credentials = new ProfileCredentialsProvider();
    	
        client = new AmazonGlacierClient(credentials);
        client.setEndpoint("https://glacier.us-west-2.amazonaws.com/");

        try {
            ArchiveTransferManager atm = new ArchiveTransferManager(client, credentials);
            
            UploadResult result = atm.upload(vaultName, "my archive " + (new Date()), new File(archiveToUpload));
            System.out.println("Archive ID: " + result.getArchiveId());
            
        } catch (Exception e)
        {
            System.err.println(e);
        }
    }
}

使用的低级 API 在单个操作中上传档案 适用于 Java 的 Amazon SDK

该低级 API 为所有归档操作提供了方法。下面是使用 适用于 Java 的 Amazon SDK上传存档的步骤。

以下 Java 代码段说明了前面的步骤。

AmazonGlacierClient client;

UploadArchiveRequest request = new UploadArchiveRequest()
    .withVaultName("*** provide vault name ***")
    .withChecksum(checksum)
    .withBody(new ByteArrayInputStream(body))
    .withContentLength((long)body.length);

UploadArchiveResult uploadArchiveResult = client.uploadArchive(request);

System.out.println("Location (includes ArchiveID): " + uploadArchiveResult.getLocation());
