Object Storage Service:Query bucket information

Sample code

The following code provides an example on how to query information about a bucket, including the region and creation date of the bucket:

const OSS = require('ali-oss'); const client = new OSS({ // Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to oss-cn-hangzhou. region: 'yourRegion', // Obtain access credentials from environment variables. Before you run the sample code, make sure that you have configured environment variables OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET. accessKeyId: process.env.OSS_ACCESS_KEY_ID, accessKeySecret: process.env.OSS_ACCESS_KEY_SECRET, authorizationV4: true, // Specify the name of your bucket. bucket: 'yourBucketName', }); async function getBucketInfo() { // Specify the name of the bucket. Example: examplebucket. const bucket = 'examplebucket' const result = await client.getBucketInfo(bucket) // Query the region of the bucket. console.log(result.bucket.Location) // Query the name of the bucket. console.log(result.bucket.Name) // Query the ID of the bucket owner. console.log(result.bucket.Owner.ID) // Query the name of the bucket owner. The name is currently the same as the ID of the bucket owner. console.log(result.bucket.Owner.DisplayName) // Query the creation time of the bucket. console.log(result.bucket.CreationDate) // Query the storage class of the bucket. console.log(result.bucket.StorageClass) // Query the versioning status of the bucket. console.log(result.bucket.Versioning) } getBucketInfo()
