Object Storage Service:Download objects to the local memory

Sample code

The following sample code provides an example on how to download an object to the local memory:

const OSS = require('ali-oss');

const client = new OSS({
  // Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to oss-cn-hangzhou. 
  region: 'yourregion',
  // Obtain access credentials from environment variables. Before you run the sample code, make sure that you have configured environment variables OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET. 
  accessKeyId: process.env.OSS_ACCESS_KEY_ID,
  accessKeySecret: process.env.OSS_ACCESS_KEY_SECRET
  // Specify the name of the bucket. 
  bucket: 'yourbucketname', 
});

async function getBuffer () {
  try {
    const result = await client.get('object-name');
    console.log(result.content);
  } catch (e) {
    console.log(e);
  }
}

getBuffer();
