获取桶列表(HarmonyOS SDK)

// 引入依赖包

  // 推荐通过环境变量获取AKSK，这里也可以使用其他外部引入方式传入，如果使用硬编码可能会存在泄露风险
  // 您可以登录访问管理控制台获取访问密钥AK/SK，获取方式请参见https://support.huaweicloud.com/usermanual-ca/ca_01_0003.html
  AccessKeyId: processManager.getEnvironmentVar("ACCESS_KEY_ID"),
  SecretAccessKey: processManager.getEnvironmentVar("SECRET_ACCESS_KEY"),
  // 【可选】如果使用临时AK/SK和SecurityToken访问OBS，同样建议您尽量避免使用硬编码，以降低信息泄露风险。您可以通过环境变量获取访问密钥AK/SK，也可以使用其他外部引入方式传入
  // SecurityToken: processManager.getEnvironmentVar("SECURITY_TOKEN"),
  // Server填写Bucket对应的Endpoint, 这里以华北-北京四为例，其他地区请按实际情况填写
  Server: "https://obs.cn-north-4.myhuaweicloud.com",
