If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.
Sample code:
// 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'); // Create an instance of ObsClient. var obsClient = new ObsClient({ //Obtain an AK/SK pair using environment variables or import the 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, server : 'https://your-endpoint' }); obsClient.getObject({ Bucket : 'bucketname', Key : 'objectname', SaveAsStream : true }, (err, result) => { if(err){ console.error('Error-->' + err); }else{ console.log('Status-->' + result.CommonMsg.Status); if(result.CommonMsg.Status < 300 && result.InterfaceResult){ // Read the object content. console.log('Object Content:\n'); result.InterfaceResult.Content.on('data', (data) => { console.log(data.toString()); }); } } });
- Use the SaveAsStream parameter to specify the download mode to streaming download.
- InterfaceResult.Content is an instance of stream.Readable and can be used to save the object content to a local file or the memory.
