Obtaining Object Properties
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.
You can call ObsClient.getObjectMetadata to obtain properties of an object, including the length, MIME type, customized metadata. Sample code is as follows:
// 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 ObsClient instance. 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.getObjectMetadata({ Bucket : 'bucketname', // prefix: Optional. It indicates the name of the folder before the object. Key : '[prefix/]objectname' }, (err, result) => { if(err){ console.error('Error-->' + err); }else{ console.log('Status-->' + result.CommonMsg.Status); if(result.CommonMsg.Status < 300 && result.InterfaceResult){ console.log(result.InterfaceResult.ContentType); console.log(result.InterfaceResult.ContentLength); console.log(result.InterfaceResult.Metadata['property']); } } });
