Abstract

A method, system, and server for issuing directory tree data and a client. The method includes: pre-storing Identities (IDs) for data blocks obtained by dividing directory tree data according to an agreed protocol, and generating and storing validity IDs for the data blocks according to the agreed protocol; receiving, by a directory tree server, an ID and a validity ID of a data block that the client requests to download, and querying for a validity ID of a data block having the same ID at a directory tree server side. If the validity ID of the data block having the same ID at the directory tree server side is the same as the validity ID received from the client, issuing a matching success message to the client; otherwise, issuing, a matching failure message and the data block at the directory tree server side having the same ID to the client.

Claims

1. A method for issuing directory tree data, comprising:

transmitting, by a client device, an Identity (ID), and a validity ID of a data block stored in the client device to a directory tree server device;

wherein the data block stored in the client device is to be updated, and the validity ID of the data block is a hash value of the data block, such that the directory tree server device finds a data block which is stored in the director tree server device and has an ID identical with the ID transmitted by the client device, and determines whether the validity ID transmitted by the client device is the same as a validity ID of the data block stored in the directory tree server device;

in response to receiving a matching success message which is issued by the directory tree server device if the validity ID transmitted by the client device is the same as the validity ID of the data block stored in the directory tree server device, keeping, by the client device, the data block to be updated in the client device unchanged, assembling the data block in the client device and other data blocks in the client device to obtain assembled data, and logging on a game platform server using the assembled data;

in response to receiving a matching failure message and the data block stored in the directory tree server device which are issued by the directory tree server device if the validity ID transmitted by the client device is different from the validity ID of the data block stored in the director tree server device, updating, by the client device, the data block to be updated in the client device with the data block received from the directory tree server device, assembling the updated data block with other data blocks in the client device to obtain assembled data, and logging on a game platform server using the assembled data; and

if the client device does not receive the matching success message or the matching failure message from the directory tree server device within a pre-defined time period, assembling, by the client device, the data block to be updated in the client device with other data blocks in the client device to obtain assembled data and logging on the game platform server using the assembled data.

2. The method of claim 1, wherein if the validity ID transmitted by the client device is an invalid value, finding, by the directory tree server device, the data block which is stored in the directory tree server device and has the ID identical with the ID transmitted by the client device, and issuing, by the directory tree server device, the data block stored in the directory tree server device to the client device.

3. A system for issuing directory tree data, comprising:

a directory tree server device and a client device;

wherein

the directory tree server device (i) receives an Identity (ID), and a validity ID of a data block stored in the client device from the client device, wherein the data block stored in the client device is to be updated, and the validity ID of the data block is a hash value of the data block, (ii) finds a data block which is stored in the director tree server device and has an ID identical with the ID received from the client device;

(iii) determines whether the validity ID received from the client device is the same as a validity ID of the data block stored in the directory tree server device;

(iv) issues a matching success message to the client device if the validity ID of the data block stored in the directory tree server device is the same as the validity ID received from the client device, and issues a matching failure message and the data block stored in the directory tree server device to the client device if the validity ID of the data block stored in the directory tree server device is different from the validity ID received from the client device; and

the client device (i) transmits the ID and the validity ID of the data block stored in the client device to the directory tree server device, (ii) in response to receiving the matching success message, keeps the data block in the client device unchanged, assembles the data block in the client device with other data blocks in the client device to obtain assembled data and logs on a game platform server using the assembled data;

(iii) in response to receiving the matching failure message and the data block stored in the directory tree server device, updates the data block to be updated in the client device with the data block received from the director tree server device, assembles the updated data block with other data blocks in the client device to obtain assembled data, and logs on the game platform server using the assembled data; and

(iv) if the client device does not receive the matching success message or the matching failure message from the director tree server device within a pre-defined time period, the client device assembles the data block to be updated in the client device with other data blocks in the client device to obtain assembled data and logs on the game platform server using the assembled data.

4. The system of claim 3, wherein the directory tree server device is further adapted to find, if the validity ID transmitted by the client device is an invalid value, the data block which is stored in the directory tree server device and has the ID identical with the ID transmitted by the client device, and issue the data block stored in the directory tree server device to the client device.

5. A client device, comprising:

an ID generating unit, a transmitting unit, an updating unit, a local data storing unit, a data assembling unit and a logon unit;

wherein

the ID generating unit is adapted to generate an Identity (ID) and a validity ID for a data block stored in local data storing unit, wherein the data block stored in the local data storing unit is to be updated, and the validity ID is a hash value of the data block;

the transmitting unit is adapted to transmit the ID and the validity ID of the data block to a directory tree server device, such that the directory tree server device finds a data block which is stored in the directory tree server device and has an ID identical with the ID transmitted by the transmitting unit, and determines whether the validity ID transmitted by the transmitting unit is the same as a validity ID of the data block stored in the directory tree server device;

the updating unit is adapted to (i) keep the data block stored in the local data storing unit unchanged in response to receiving a matching success message which is issued by the directory tree server device if the validity ID transmitted by the client device is the same as the validity ID of the data block stored in the directory tree server device, and transmit an assembling indication to the data assembling unit, (ii) in response to receiving a matching failure message and the data block stored in the directory tree server device which are issued by the directory tree server device if the validity ID transmitted by the client device is different from the validity ID of the data block stored in the directory tree server device, update the data block in the local data storing unit with the data block received from the directory tree server device, and transmit an assembling indication to the data assembling unit after the data block to be updated in the client device is updated; and

(iii) in response to not receiving the matching success message or the matching failure message from the directory tree server device within a pre-defined time period, transmit an assembling indication to the data assembling unit;

the local data storing unit is adapted to store the data block to be updated and other data blocks of the client device;

the data assembling unit is adapted to assemble the data block with the other blocks in the local data storing unit to obtain assembled data, and transmit a logon indication to the logon unit; and

the logon unit is adapted to log on a game platform server using the assembled data obtained by the data assembling unit after receiving the logon indication.
