Sample Code

You can call ObsClient.deleteBucketMirrorBackToSource to delete back-to-source by mirroring rules. The sample code is as follows:

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

// Create an ObsClient instance.
const obsClient = new ObsClient({
  // Obtain an AK and SK pair using environment variables (recommended) or import it 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 not advised 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 bucket. CN-Hong Kong is used here as an example. Replace it with the one currently in use.
  server: "https://obs.ap-southeast-1.myhuaweicloud.com"
