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, and customized metadata. Sample code is as follows:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret Key ***',       
    server : 'https://your-endpoint'
});

obsClient.getObjectMetadata({
       Bucket : 'bucketname',
       Key : 'objectname'
}, function (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']); 
          }
       }
});

To obtain the customized metadata of an object, you need to add the additional headers that are allowed to be carried in responses to the CORS configurations. For example, you can add x-obs-meta-property to enable the query of property.
