Creating a Bucket

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

You can call ObsClient.createBucket to create a bucket. When creating a bucket, you can specify the ACL, storage class, and location for the bucket. OBS provides three storage classes for buckets. For details, see Storage Class. Sample code is as follows:
// Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use the source code to install the client.
// var ObsClient = require('./lib/obs');

// Create an ObsClient instance.
var obsClient = new ObsClient({
       //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways. Using hard coding may result in leakage.
       //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
       access_key_id: process.env.ACCESS_KEY_ID,
       secret_access_key: process.env.SECRET_ACCESS_KEY,
       server : 'https://your-endpoint'
});

// Create a bucket.
obsClient.createBucket({
       Bucket : 'bucketname',
       // Set the access permission for the bucket to public-read (the default value is private.)
       ACL : obsClient.enums.AclPublicRead,
       //Set the storage class to Archive.
       StorageClass : obsClient.enums.StorageClassStandard,
       // Configure the bucket region.
       Location : 'bucketlocation',
       
       
}, (err, result) => {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});
  • Bucket names are globally unique. Ensure that the bucket you create is named differently from any other bucket.
  • A bucket name must comply with the following rules:
    • Contains 3 to 63 characters, chosen from lowercase letters, digits, hyphens (-), and periods (.), and starts with a digit or letter.
    • Cannot be an IP address.
    • Cannot start or end with a hyphen (-) or period (.)
    • Cannot contain two consecutive periods (.), for example, my..bucket.
    • Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket.
  • If you create buckets of the same name in a region, no error will be reported and the bucket properties comply with those set in the first creation request.
  • The bucket created in the previous example is of the default ACL (private), in the OBS Standard storage class, and in the default region where the global domain resides.
  • You can use parameter ACL to specify the access permission, use StorageClass to specify the storage class, and use Location to specify the location for a bucket.
  • During bucket creation, if the endpoint you use corresponds to the default region CN North-Beijing1 (cn-north-1), specifying a region is not a must. If the endpoint you use corresponds to any other region, except the default one, you must set the region to the one that the used endpoint corresponds to. To view the valid regions, see Regions and Endpoints. For example, if the endpoint used for initialization is obs.ap-southeast-1.myhuaweicloud.com, you must set Location to ap-southeast-1 when you create a bucket. Otherwise, status code 400 will be returned.
