Setting or Obtaining a Bucket Quota

Setting a Bucket Quota

You can call ObsClient.setBucketQuota to set the bucket quota. Sample code is as follows:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
    // The front-end code does not have the process environment variable, so you need to use a module bundler like webpack to define the process variable.
    // Obtain an AK/SK pair on the management console.
    access_key_id: process.env.AccessKeyID,
    secret_access_key: process.env.SecretAccessKey,
    server: 'https://your-endpoint'
});

//Set the bucket quota to 100 MB.
obsClient.setBucketQuota({
       Bucket: 'bucketname',
       StorageQuota: 1024 * 1024 * 100
}, function (err, result) {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});
  • Use the StorageQuota parameter to specify the bucket quota.
  • A bucket quota must be a non-negative integer expressed in bytes. The maximum value is 263 - 1.

Obtaining a Bucket Quota

You can call ObsClient.getBucketQuota to obtain the bucket quota. Sample code is as follows:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables AccessKeyID and SecretAccessKey.
    // The front-end code does not have the process environment variable, so you need to use a module bundler like webpack to define the process variable.
    // Obtain an AK/SK pair on the management console.
    access_key_id: process.env.AccessKeyID,
    secret_access_key: process.env.SecretAccessKey,
    server: 'https://your-endpoint'
});

obsClient.getBucketQuota({
       Bucket : 'bucketname'
}, function (err, result) {
       if(err){
              console.error('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                     console.log('StorageQuota-->' + result.InterfaceResult.StorageQuota);
              }
       }
});
