详细介绍一下 s3 的 bucket 桶操作有哪些

Amazon S3 提供了一系列对存储桶(bucket)的操作,涵盖创建、配置、管理和删除存储桶等。以下是详细介绍 S3 存储桶操作的各个方面:

1. 创建存储桶

1.1 创建存储桶

  • 操作CreateBucket
  • 描述:创建一个新的 S3 存储桶。
  • 示例代码
      AmazonS3 s3Client = AmazonS3ClientBuilder.standard().build();
      s3Client.createBucket(new CreateBucketRequest("my-bucket"));
    

2. 配置存储桶

2.1 设置存储桶策略

  • 操作PutBucketPolicy
  • 描述:设置或更新存储桶的访问策略。
  • 示例代码
      String bucketPolicy = "{...}";
      s3Client.setBucketPolicy("my-bucket", bucketPolicy);
    

2.2 配置 CORS(跨域资源共享)

  • 操作PutBucketCors
  • 描述:配置存储桶的 CORS 规则。
  • 示例代码
      BucketCrossOriginConfiguration configuration = new BucketCrossOriginConfiguration().withRules(rules);
      s3Client.setBucketCrossOriginConfiguration("my-bucket", configuration);
    

2.3 配置生命周期规则

  • 操作PutBucketLifecycleConfiguration
  • 描述:配置存储桶的生命周期规则。
  • 示例代码
      BucketLifecycleConfiguration.Rule rule = new BucketLifecycleConfiguration.Rule().withId("rule-id").withStatus(BucketLifecycleConfiguration.ENABLED).withTransition(new BucketLifecycleConfiguration.Transition().withDays(30).withStorageClass(StorageClass.Glacier));
      BucketLifecycleConfiguration configuration = new BucketLifecycleConfiguration().withRules(rule);
      s3Client.setBucketLifecycleConfiguration("my-bucket", configuration);
    

2.4 配置版本控制

  • 操作PutBucketVersioning
  • 描述:启用或暂停存储桶的版本控制。
  • 示例代码
      BucketVersioningConfiguration configuration = new BucketVersioningConfiguration().withStatus(BucketVersioningConfiguration.ENABLED);
      s3Client.setBucketVersioningConfiguration(new SetBucketVersioningConfigurationRequest("my-bucket", configuration));
    

2.5 配置日志记录

  • 操作PutBucketLogging
  • 描述:配置存储桶的访问日志记录。
  • 示例代码
      BucketLoggingConfiguration loggingConfiguration = new BucketLoggingConfiguration().withDestinationBucketName("log-bucket").withLogFilePrefix("my-bucket-logs/");
      s3Client.setBucketLoggingConfiguration(new SetBucketLoggingConfigurationRequest("my-bucket", loggingConfiguration));
    

3. 管理存储桶

3.1 列出存储桶

  • 操作ListBuckets
  • 描述:列出账户下的所有存储桶。
  • 示例代码
      List<Bucket> buckets = s3Client.listBuckets();
      for (Bucket bucket : buckets) {
          System.out.println(bucket.getName());
      }
    

3.2 获取存储桶信息

  • 操作GetBucketLocation
  • 描述:获取存储桶的位置。
  • 示例代码
      String location = s3Client.getBucketLocation(new GetBucketLocationRequest("my-bucket"));
      System.out.println(location);
    

3.3 获取存储桶策略

  • 操作GetBucketPolicy
  • 描述:获取存储桶的访问策略。
  • 示例代码
      String bucketPolicy = s3Client.getBucketPolicy("my-bucket").getPolicyText();
      System.out.println(bucketPolicy);
    

3.4 获取存储桶 CORS 配置

  • 操作GetBucketCors
  • 描述:获取存储桶的 CORS 配置。
  • 示例代码
      BucketCrossOriginConfiguration corsConfiguration = s3Client.getBucketCrossOriginConfiguration("my-bucket");
    

3.5 获取存储桶生命周期配置

  • 操作GetBucketLifecycleConfiguration
  • 描述:获取存储桶的生命周期配置。
  • 示例代码
      BucketLifecycleConfiguration lifecycleConfiguration = s3Client.getBucketLifecycleConfiguration("my-bucket");
    

3.6 获取存储桶版本控制状态

  • 操作GetBucketVersioning
  • 描述:获取存储桶的版本控制状态。
  • 示例代码
      BucketVersioningConfiguration versioningConfiguration = s3Client.getBucketVersioningConfiguration(new GetBucketVersioningConfigurationRequest("my-bucket"));
    

4. 删除存储桶

4.1 删除存储桶

  • 操作DeleteBucket
  • 描述:删除指定的存储桶(存储桶必须为空)。
  • 示例代码
      s3Client.deleteBucket("my-bucket");
    

总结表

操作类别 操作名称 描述 示例代码
