Object Storage Service:Obtain the storage capacity of a bucket (Node.js SDK)

Precautions

You must have the oss:GetBucketStat permission to obtain the storage capacity of a bucket. For more information, see Common examples of RAM policies.

Example code

The following code shows how to obtain the total storage capacity of a bucket named examplebucket, and the number and storage capacity of objects for each storage class in the bucket.

const OSS = require("ali-oss");
const client = new OSS({
  // Set yourRegion to the region where the bucket is located. For example, if the bucket is in the China (Hangzhou) region, set the region to oss-cn-hangzhou.
  region: "oss-cn-hangzhou",
  // Obtain access credentials from environment variables. Before running the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured.
  accessKeyId: process.env.OSS_ACCESS_KEY_ID,
  accessKeySecret: process.env.OSS_ACCESS_KEY_SECRET,
  authorizationV4: true,
  // Set yourBucketName to the name of the bucket.
  bucket: 'yourBucketName',
});

async function getBucketStat() {
  // Specify the bucket name. For example, examplebucket.
  const bucket = "examplebucket";
  try {
    const stat = await client.getBucketStat(bucket);
    console.log("Total storage capacity of the bucket", stat.stat.Storage);
    console.log("Total number of objects in the bucket", stat.stat.ObjectCount);
    console.log(
      "Number of multipart uploads that are initiated but not completed or aborted",
      stat.stat.MultipartUploadCount
    );
    console.log("Number of LiveChannels", stat.stat.LiveChannelCount);
    console.log("All successfully uploaded parts", stat.stat.MultipartPartCount);
    console.log("Number of delete markers", stat.stat.DeleteMarkerCount);
    console.log("Time when the storage information was retrieved", stat.stat.LastModifiedTime);
    console.log("Storage capacity of the Standard storage class", stat.stat.StandardStorage);
    console.log("Number of objects in the Standard storage class", stat.stat.StandardObjectCount);
    console.log("Billed storage capacity of the Infrequent Access storage class", stat.stat.InfrequentAccessStorage);
    console.log(

      stat.stat.InfrequentAccessRealStorage
    );
    console.log(
      "Number of objects in the Infrequent Access storage class",
      stat.stat.InfrequentAccessObjectCount
    );
    console.log("Billed storage capacity of the Archive Storage class", stat.stat.ArchiveStorage);
    console.log("Actual storage capacity of the Archive Storage class", stat.stat.ArchiveRealStorage);
    console.log("Number of objects in the Archive Storage class", stat.stat.ArchiveObjectCount);
    console.log("Billed storage capacity of the Cold Archive storage class", stat.stat.ColdArchiveStorage);
    console.log("Actual storage capacity of the Cold Archive storage class", stat.stat.ColdArchiveRealStorage);
    console.log("Number of objects in the Cold Archive storage class", stat.stat.ColdArchiveObjectCount);
    console.log(
      "Billed storage capacity of the Deep Cold Archive storage class",
      stat.stat.DeepColdArchiveStorage
    );
    console.log(
      "Actual storage capacity of the Deep Cold Archive storage class",
      stat.stat.DeepColdArchiveRealStorage
    );
    console.log(
      "Number of objects in the Deep Cold Archive storage class",
      stat.stat.DeepColdArchiveObjectCount
    );
  } catch (error) {
    console.error("Error obtaining bucket statistics:", error);
  }
}
getBucketStat();
