As the initial step, fetch the private key and certificate of the root identity:

```sh

	// assert the http response.
	c.Assert(response.StatusCode, http.StatusOK)

	// make HTTP request to fetch the object.
	request, err = newTestSignedRequest(http.MethodGet, getGetObjectURL(s.endPoint, bucketName, objectName),
		0, nil, s.accessKey, s.secretKey, s.signer)
	c.Assert(err, nil)

	// execute the http request to fetch object.
	response, err = s.client.Do(request)
	c.Assert(err, nil)
	// assert the http response status code.

                     'Message: {}').format(self.root_name, name, error.message)
                )
        else:
            return self.element.findtext('sts:{}'.format(name), None, _STS_NS)

    def text(self):
        """Fetch the current node's text

        """

	}

}

// Fetch claims in the security token returned by the client, doesn't return

	return nil
}

// GetLocks - fetch older locks for a remote node.
func (client *peerRESTClient) GetLocks() (lockMap map[string][]lockRequesterInfo, err error) {
	resp, err := getLocksRPC.Call(context.Background(), client.gridConn(), grid.NewMSS())

	}
	return *resp, nil
}

// LocalStorageInfo - fetch server information for a remote node.

	// Should not be combined with ReturnLastGood.
	CacheError bool

	// If NoWait is set, Get() will return the last good value,
	// if TTL has expired but 2x TTL has not yet passed,
	// but will fetch a new value in the background.
	NoWait bool
}

// Cache contains a synchronized value that is considered valid
// for a specific amount of time.
// An Update function must be set to provide an updated value when needed.

// objSweeper determines if a transitioned object needs to be removed from the remote tier.
// A typical usage would be like,

// goiOpts := os.GetOpts()
// gerr := objAPI.GetObjectInfo(ctx, bucket, object, goiOpts)
//
//	if gerr == nil {
//	   os.SetTransitionState(goi)
//	}
//
