Initializing an Instance of ObsClient (SDK for Node.js)

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

Each time you want to send an HTTP/HTTPS request to OBS, you must create an instance of ObsClient. Sample code is as follows:

// 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 as an example. Replace it with the one currently in use.
  server: "https://obs.ap-southeast-1.myhuaweicloud.com"
});

// Use the instance to access OBS.

// Close the ObsClient instance.
// obsClient.close();
  • JavaScript is an asynchronous programming language. Therefore, you cannot call the close method when accessing OBS.
  • An ObsClient instance cannot be used again after it is closed by calling obsClient.close.
