Obtaining the Logging Configuration of a Bucket (SDK for Node.js)

If you have any questions during development, post them on the Issues page of GitHub.

Function

This API returns the logging configuration of a bucket.

Restrictions

To obtain the logging configuration of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketLogging in IAM or GetBucketLogging in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
To learn about the mappings between OBS regions and endpoints, see Regions and Endpoints.

Method

ObsClient.getBucketLogging(params)

Request Parameters

**Table 1** BucketRequestInput
Parameter	Type	Mandatory (Yes/No)	Description
Bucket	string	Yes	Explanation: Bucket name. Restrictions: A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain a period (.) and a hyphen (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets with the same name in the same region, no error will be reported, and the bucket attributes comply with those set in the first creation request. Value range: The value can contain 3 to 63 characters. Default value: None

**Table 11** PermissionType
Constant	Default Value	Description
ObsClient.enums.PermissionRead	READ	A grantee with this permission for a bucket can obtain the list of objects, multipart uploads, bucket metadata, and object versions in the bucket. A grantee with this permission for an object can obtain the object content and metadata.
ObsClient.enums.PermissionWrite	WRITE	A grantee with this permission for a bucket can upload, overwrite, and delete any object or part in the bucket. This permission is not applicable to objects.
ObsClient.enums.PermissionReadAcp	READ_ACP	A grantee with this permission can obtain the ACL of a bucket or object. A bucket or object owner has this permission for their bucket or object by default.
ObsClient.enums.PermissionWriteAcp	WRITE_ACP	A grantee with this permission can update the ACL of a bucket or object. A bucket or object owner has this permission for their bucket or object by default. This permission allows the grantee to change the access control policies, meaning the grantee has full control over a bucket or object.
ObsClient.enums.PermissionFullControl	FULL_CONTROL	A grantee with this permission for a bucket has PermissionRead, PermissionWrite, PermissionReadAcp, and PermissionWriteAcp permissions for the bucket. A grantee with this permission for an object has PermissionRead, PermissionReadAcp, and PermissionWriteAcp permissions for the object.

Code Examples

You can call ObsClient.getBucketLogging to view the logging configuration of a bucket. The following code shows how to obtain the logging configuration of bucket examplebucket:

    
     
       
       
         // Import the OBS library.
// Use npm to install the client.
const ObsClient = require("esdk-obs-nodejs");
// Use the source code to install the client.
// var ObsClient = require('./lib/obs');

// Create an instance of ObsClient.
const obsClient = new ObsClient({
  //Obtain an AK/SK pair using environment variables or import an 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,
  // (Optional) If you use a temporary AK/SK pair and a security token to access OBS, you are advised not to use hard coding, which may result in information leakage. You can obtain an AK/SK pair using environment variables or import an AK/SK pair in other ways.
  // security_token: process.env.SECURITY_TOKEN,
  // Enter the endpoint corresponding to the region where the bucket is located. CN-Hong Kong is used here in this example. Replace it with the one currently in use.
  server: "https://obs.ap-southeast-1.myhuaweicloud.com"
});
