Abstract
A method and a device for acquiring bit torrent (BT) resource information are provided. When interacting with a peered terminal for exchanging the data of a BT resource, in the case that a local terminal does not have the metadata of the BT resource, the local terminal, after performing the BT protocol handshake, determines the number of data slices of the BT resource based on the bitmap A of the BT resource sent by the peered terminal, and then a NOT operation of the bitmap A is performed, and the bitmap B obtained through the NOT operation is fed back to the peered terminal to trigger the peered terminal to send an acquisition request to the local terminal for the data blocks of the BT resource.
