Obtaining Static Website Hosting Configurations (SDK for Node.js)

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

Function

You can host static website resources such as HTML web pages, flash files, or audio and video files in an OBS bucket, so that you can provide these hosted resources using the bucket's website endpoint to end users. Typical use cases include:

Redirecting all requests to another website
Redirecting specific requests

This API returns the static website hosting configurations of the bucket.

Restrictions

To obtain the static website hosting configurations of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketWebsite in IAM or GetBucketWebsite in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.

Method

ObsClient.getBucketWebsite(params)

Code Examples

You can call ObsClient.getBucketWebsite to obtain the hosting configuration of a bucket. The following code shows how to obtain the website 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/eu/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. EU-Dublin is used here in this example. Replace it with the one currently in use.
  server: "https://obs.eu-west-101.myhuaweicloud.eu"
});
