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

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

ObsClient functions as the Node.js client for accessing OBS. It offers callers a series of APIs for interaction with OBS and is used for managing and operating resources, such as buckets and objects, stored in OBS. To use OBS Node.js SDK to send a request to OBS, you need to initialize an instance of ObsClient and modify parameters related to initial configurations of the instance based on actual needs.

By Using the Constructor

  • Sample code for creating an ObsClient instance using permanent access keys (AKs/SKs): 
    // 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,
  // 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();
  • Sample code for creating an ObsClient instance using temporary security credentials (AKs/SKs and security tokens): 
    // 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,
  // 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();

By Using the Factory Method

  • Sample code for creating an ObsClient instance using permanent access keys (AKs/SKs): 
    // Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use the source code to install the client.
// var ObsClient = require('./lib/obs');

// Initialize an ObsClient instance by using the factory method.
var obsClient = new ObsClient();
obsClient.factory({
  // 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,
  // 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();
  • Sample code for creating an ObsClient instance using temporary security credentials (AKs/SKs and security tokens): 
    // Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use the source code to install the client.
// var ObsClient = require('./lib/obs');

// Initialize an ObsClient instance by using the factory method.
var obsClient = new ObsClient();
obsClient.factory({
  // 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,
  // 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();
  • The project can contain one or more ObsClient instances.
