Specific embodiment

To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into It is described in detail to one step, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementation Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts All other embodiment, shall fall within the protection scope of the present invention.

During client device is synchronous with server progress data, in order to avoid transmitting duplicate data information, A kind of possible implementation are as follows: the resource data that will be installed in the resource data packet 2 installed in server and client device Packet 1 compares, and determines that the check information between resource data packet 2 and resource data packet 1, check information can be used for identifying text Different information between part a2 and file a1, so that different information can be sent to client device by server, so that Client device is updated resource data packet 1.In this implementation, determine that the executing subject of check information can be visitor Family end equipment, or it is also possible to server, specifically it is not construed as limiting.

For determining that the executing subject of check information is server, according to above content it is found that if what server determined Check information is more accurate, then server can obtain accurate different information according to accurate check information, so that clothes Accurate different information can be sent to client device by business device, improve the synchronous efficiency of data.That is, check information Accuracy will affect the accuracy of different information, if want guarantee different information accuracy, need server to get standard True check information.However, there are no a kind of accurate modes for obtaining check information at this stage, therefore, at this stage in client Carried out between equipment and server data it is synchronous when, exist the duplicate data information of transmission, network flow loss it is larger and The lower technical problem of the synchronous efficiency of data.

Fig. 1 is a kind of corresponding flow diagram of data processing method provided in an embodiment of the present invention, this method comprises:

Step 101, server obtains the first information that client device is sent.

It can store the first data packet in the embodiment of the present invention, in client device, can store in server Two data packets.Wherein, the second data packet in server can be to be updated to the third data packet stored in server The data packet arrived, third data packet can be identical as the first data packet, or can also be different from the first data packet, do not make specifically It limits.For example, can be equipped with same resource data packet in server and client side's equipment, installed on client device Resource data packet be the corresponding resource data packet of version V1.1 (i.e. the first data packet), and the resource data installed on server Packet is the corresponding resource data packet of version V1.3 (i.e. the second data packet)；In one example, if the version installed on server The corresponding resource data packet of V1.3 is corresponding resource data packet (the i.e. third data of version V1.1 to installation former on server Packet) upgraded, i.e., version V1.3 is upgraded to obtain to version V1.1, then in this example, the first data Packet and third data packet can be identical (being the corresponding resource data packet of version V1.1)；In another example, if server The corresponding resource data packet of the version V1.3 of upper installation is the corresponding resource data packet of version V1.2 to installation former on server (i.e. third data packet) is upgraded, i.e., version V1.3 is upgraded to obtain to version V1.2, and version V1.2 It is to be upgraded to version V1.1, then in this example, the first data packet and third data packet can be different, the first number It can be the corresponding resource data packet of version V1.1 according to packet, third data packet can be the corresponding resource data packet of version V1.2.

The following example of the invention is to use the second data packet in server to the first data in client device Illustrate the scheme in the embodiment of the present invention for the synchronous process of packet progress data, it is possible to understand that, it is carried out between other equipment The data synchronization process that the synchronous process of data is also referred in the embodiment of the present invention is realized, is specifically not construed as limiting.

In the embodiment of the present invention, the first information may include the data volume of corresponding N number of first data block of the first data packet Check value corresponding with N number of first data block.In specific implementation, client device can be according to the data of the first data packet First data packet is divided into N number of first data block by amount.Wherein, the mode the first data packet divided can there are many, In one possible implementation, the first data packet can be divided into N number of first according to preset data amount by client device The data volume of data block, each first data block can be identical.For example, the data volume of the first data packet is 905M, to the One data packet carries out dividing the available first data block data block of b1~first b10；Wherein, the first data block b1~the nine the The data volume of each first data block can be 100M in one data block b9, and the data volume of the first data block b10 can be 5M.

Further, it is directed to the first data block of each of the first data block of data block b1~first b10, can be determined The corresponding check value of each first data block.The corresponding check value of each first data block can be the of each first data block One check value (strong check value), or may be the second check value (strong check value) of each data block.Correspondingly, the first letter The check value for the first data block of data block b1~first b10 for including in breath can be the first data block of data block b1~first The first check value of b10 perhaps may be the second check value of the first data block of data block b1~first b10 or may be used also With the second of the first check value of the first data block of data block b1~first b10 and the first data block of data block b1~first b10 Check value is specifically not construed as limiting.

First check value can be a kind of strong check value, such as MD5 check value.MD5 check value can add salt to pass through band MD5 hash mode or without the key for adding the MD5 hash mode of salt to obtain, acquisition process is irreversible encrypted Journey can not obtain the information of the data by the corresponding MD5 check value of a certain data.Correspondingly, according to identical encryption After mode (such as MD5 hash mode of band plus salt) encrypts the first data of file and the second data respectively, the first data Corresponding key key corresponding with the second data is identical, it can be said that bright first data are identical as the second data.To determine the For the first check value of one data block b1, in specific implementation, the first data block b1 can be divided into 512 first point in advance Group, and each first grouping is divided into 32 the first subgroups.Further, by using the mode of MD5 Hash to 512 First grouping is encrypted, available four 32 the second subgroups, this four 32 second subgroup is carried out grade After connection, available one 128 hashed values.Wherein, which can be for corresponding first school the first data block b1 Test value.The reliability of first check value is stronger, and verification is obtained according to corresponding first check value of N number of first data block Information can submit the accuracy of check information.

Second check value can be a kind of weak check value, for example determined based on checksum algorithm (i.e. Asler32 algorithm) Check value.Specifically, the weak check value of the first data block can be to add in the first data group to each field for including With obtain, can will obtain and value is as the first checksum value；It correspondingly, can will be in the mistake for determining the first checksum value The sum of Stage Value of each step is used as the second checksum value in journey.Wherein, the first checksum value and the second checksum value can be with For 16 numerical value, it is possible to further which the second checksum value of 16 the first checksum values and 16 are spliced into one 32 integers, i.e. the second check value of the first data block.

Step 102, server divides N number of first data block, obtains M group data.

In specific implementation, mode that N number of first data block is divided can there are many, in a kind of possible realization side In formula, N number of first data block can be divided into M group data according to preset data number of blocks by server, wherein every group of data Including the quantity of data block can be identical.For example, server can draw the first data block of data block b1~first b10 It is divided into the first data group~the 4th data group, wherein the number that each data group in the first data group~third data group includes Quantity according to block can be 3, and the quantity for the data block that the 4th data group includes can be 1.For example, the first data group includes First data block of data block b1~first b3, the second data group include the first data block b6 of data block b4~first, third data Group includes the first data block of data block b7~first b9, and the 4th data group includes the first data block b10.That is, the first number It can be 300M according to the data volume of each data group in group~third data group, the data volume of the 4th data group can be 5M.

Step 103, server determines the check information of every group of data in M group data.

In one possible implementation, server if it is determined that maximum amount of data in M group data be greater than or equal to it is N number of Minimum data amount in the data volume of first data block, the then process for illustrating that server verifies the second data packet are not tied Beam can continue to execute subsequent step.Herein, the minimum data amount in the data volume of N number of first data block can refer to N number of The data volume of the smallest first data block of data volume in first data block.For example, the first data block of data block b1~first b10 Minimum data amount in data volume can refer to the data volume of the first data block b10, i.e. 5M.

It should be noted that above-mentioned implementation is only a kind of illustrative simple declaration, cited by determine service The unclosed condition of the process that device verifies the second data packet is merely for convenience and purposes of illustration of scheme, does not constitute to scheme It limits.In specific implementation, determine that the unclosed condition of process that server verifies the second data packet can be by ability Field technique personnel are configured according to the actual situation, for example preset data amount threshold value can be set, however, it is determined that in M group data most Big data quantity is greater than or equal to preset data amount threshold value, then can determine process that server verifies the second data packet not Terminate；Wherein, preset data amount threshold value can be fixed numerical value, or may be according to the minimum number in the first data block Obtained numerical value is determined according to amount, for example can be 3/4 of the minimum data amount in the first data block, is specifically not construed as limiting.

It may include the first data block b6 of data block b4~first by taking the second data group as an example, in the second data group, specifically In implementation, the corresponding check value of the first data block of data block b4~first b6 that can include according to the second data group, really The fixed corresponding check value of second data group.Several possible feelings of the corresponding check value of determining second data group are described separately below Condition.

Further, server can be according to check value the second data packet corresponding to the first data group of the second data group It is verified.Wherein, corresponding second data packet of the first data group can be to be directed to after the first data group executes step 103 to obtain The data packet arrived.Specifically, after being verified according to the check value of the first data group to the second data packet, it can be to second Data packet is updated, and obtains corresponding second data packet of the first data group；Correspondingly, in the check value according to the second data group After the second data packet corresponding to the first data group verifies, can corresponding to the first data group the second data packet carry out more Newly, corresponding second data packet of the second data group is obtained.It should be noted that obtaining corresponding second data packet of third data group The process of the second data packet corresponding with the 4th data group is referred to the first data group and the second data group executes, no longer superfluous It states.

In specific implementation, server can in obtaining server corresponding second data packet of the first data group that store Afterwards, it since the i-th bit data in corresponding second data packet of the first data group, obtains identical as the data volume of the first data group Target set of data, and target set of data can be divided, obtain T the second data blocks；Wherein, T the second data blocks The data volumes of data volume and T the first data blocks can be identical.Further, server can be according to T the second data blocks Check value determine the corresponding check value of target set of data, for example, in the first sub- situation, server can be according to T second First check value of data block determines corresponding first check value of target set of data, and can be according to the first school of the second data group Value and corresponding first check value of target set of data are tested, the second data packet is verified, generates the corresponding school of the second data group Test information；In the second sub- situation, server can determine target set of data pair according to the first check value of T the second data blocks The second check value answered, and can according to corresponding second check value of the second check value and target set of data of the second data group, Second data packet is verified, the corresponding check information of the second data group is generated；In the sub- situation of third, server can root Corresponding first check value of target set of data and the second check value are determined according to the first check value of T the second data blocks, and can be with According to corresponding first check value of the first check value and target set of data of the second data group, the second check value of the second data group The second check value corresponding with target set of data, verifies the second data packet, generates the corresponding verification letter of the second data group Breath.Correspondingly, in the 4th sub- situation, server can determine target data according to the second check value of T the second data blocks Corresponding first check value of group, and can be according to corresponding first verification of the first check value and target set of data of the second data group Value, verifies the second data packet, generates the corresponding check information of the second data group；In the 5th sub- situation, server can To determine corresponding second check value of target set of data according to the second check value of T the second data blocks, and can be according to second Corresponding second check value of the second check value and target set of data of data group, verifies the second data packet, generates second The corresponding check information of data group；In the 6th sub- situation, server can be true according to the second check value of T the second data blocks Corresponding first check value of the data group that sets the goal and the second check value, and can be according to the first check value and mesh of the second data group The second check value and corresponding second check value of target set of data of corresponding first check value of data group, the second data group are marked, Second data packet is verified, the corresponding check information of the second data group is generated.

In the following example of the invention by taking the second sub- situation as an example specifically describe to the second data packet carry out verification and Generate the realization process of the corresponding check information of the second data group.

In specific implementation, the (the from corresponding second data packet of the first data group the 1st by taking the process that first time executes as an example Position data start), if in the second data group including the first data block b6 of data block b4~first, and the first data block b4~the first The data volume of the first data block of each of data block b6 is 100M, then in first time implementation procedure, server can be from A data in corresponding second data packet of first data group starts, and successively obtains the data of 300M as target data Group, and target set of data is divided into the second data block of data block c4~second c6；Wherein, the second data of data block c4~second The data volume of the second data block of each of block c6 can be 100M.Further, server can determine the second data block The first check value of the data block of c4~second c6, and can be according to the first check value of the second data block of data block c4~second c6 Determine target set of data the second check value (be referred to determine that the process of the second check value of the second data group is executed, It repeats no more).

Further, server can be by corresponding second check value corresponding with target set of data second of the second data group Check value compares, however, it is determined that corresponding second check value of the second data group the second check value phase corresponding with target set of data Together, then the second data group can be determined according to the T that the second data group includes corresponding first check values of the first data block Corresponding first check value, and target set of data corresponding first can be determined according to the first check value of T the second data blocks Check value.For determining the process of corresponding first check value of the second data group, specifically, if the second data group includes Corresponding first check value of first data block of data block b4~first b6 is respectively R1, R2 and R3, then can by by R1, R2 and R3 is combined into a numerical value, and then asks HD5 cryptographic Hash, i.e. corresponding first check value of the second data group to the numerical value.

If it is determined that corresponding first check value of the second data group the first check value corresponding with target set of data is identical, then take The first check information of the second data group can be generated in business device.Wherein, may include in the first check information of the second data group Position information (i.e. identification information) corresponding to target set of data identical with the first data packet in second data packet.In an example In, if corresponding second data packet of the first data group is the second data packet, the first check information of the second data group can be with Are as follows: the second data group (data of 301M in the data Yu the first data packet of 1M to 300M in the second data packet The data of 601M) it is identical.

It, can also be to the first data group pair after the first check information for generating the second data group in the embodiment of the present invention The second data packet answered is updated.For example, can be by the target set of data in corresponding second data packet of the first data group (i.e. The data of 1M to 300M) cavity is replaced with, or can also be spcial character by the data modification of 1M to 300M, or Person can also be labeled the data of 1M to 300M, specifically be not construed as limiting.

Further, server can execute above-mentioned step since the next bit data of target set of data.It needs Bright, if target set of data is identical as the second data group, during executing for second, server can be from the second number According in packet remove target set of data after the 1st data start, execute the above process.When the second data group of use is to the first data group After each data in corresponding second data packet are finished, server can be by above-mentioned execution step successively to first Corresponding second data packet of data group is updated, and obtains corresponding second data packet of the second data group.

In one possible implementation, however, it is determined that corresponding second check value of the second data group and target set of data pair The second check value answered is different, then illustrates that target set of data is different from the second data group, divided at this point, server can determine Whether journey terminates that (whole position data in the second data packet become cavity and/or have all been marked or the number of the second data group It is equal to the minimum data amount in N number of first data block according to amount, it is determined that partition process has terminated).If server determination divided Journey is not finished, then third data group can be used since the corresponding a data of the second data group, executes above-mentioned verified Journey.If server determine partition process terminated (i.e. the data volume of the second data group be equal to N number of first data block in minimum number According to amount), then the second check information of the second data group can be generated in server, and third data group can be used from the second data The corresponding a data of group starts, and executes above-mentioned checking procedure.It wherein, may include the second data packet in the second check information In position information (i.e. identification information) corresponding to the target set of data different from the first data packet.In one example, if first Corresponding second data packet of data group is the second data packet, then the second check information of the second data group can be with are as follows: the second number Data according to 1M to 300M in packet are different from the first data packet.

In the embodiment of the present invention, the first check value can be strong check value, and the second check value can be weak check value, pass through By the way of first comparing weak check value and comparing strong check value again, on the one hand purpose data group can be filtered out by weak check value In with the obvious identical data information of Y data group, thus the efficiency for mitigating workload, improving data processing；On the other hand, lead to It crosses and the corresponding check information of Y data group is determined using strong check value and weak check value jointly, it is corresponding that Y data group can be improved Check information accuracy.Further, check information may include the first check information and the second check information, the first school Testing information is the corresponding check information of identical with Y data group data information in target set of data, and the second check information can be with For the corresponding check information of data information different from Y data group in target set of data.By obtain the first check information and Second check information, the available more complete check information of server, so that client device is to server sync Data it is more accurate.

Step 104, server is if it is determined that the data volume of corresponding second data packet of M data group is less than preset data amount threshold Value, thens follow the steps 105；If it is determined that the data volume of corresponding second data packet of M data group is greater than or equal to preset data amount Threshold value thens follow the steps 102.

In the embodiment of the present invention, server is carried out using third data group the second data packet corresponding to the second data group After verification, can the second data packet corresponding to the second data group be updated, generate corresponding second data of third data group Packet.Further, server if it is determined that corresponding second data packet of third data group data volume be less than preset data amount threshold value, Then illustrate total data (i.e. whole digits in the second data packet identical as the data in the first data packet in the second data packet According to become cavity and/or all be marked, checking procedure terminates)；At this point, server can execute step 105.Wherein, in advance If data-quantity threshold can be rule of thumb configured by those skilled in the art, specifically it is not construed as limiting.

Correspondingly, server is if it is determined that the data volume of corresponding second data packet of third data group is greater than or equal to present count According to amount threshold value, then illustrate that (i.e. checking procedure is not tied in the presence of the data different from the data in the first data packet in the second data packet Beam)；At this point, server can execute step 102 again.In specific implementation, server can carry out the to N number of first data block Secondary division, if N number of first data are divided into P data group, the data for including in each data group in P data group The quantity of block can be less than or equal to the data block for dividing for the first time and including in each data group in M obtained data group Quantity.That is, P can be greater than or equal to M.

Further, server is if it is determined that the data volume of every group of data is respectively less than the number of N number of first data block in P group data According to the minimum data amount in amount, then the process for illustrating that server verifies the second data packet has terminated, at this point, server can The corresponding check information of M group data is sent to client device.Correspondingly, server is if it is determined that data volume in P group data Maximum data volume be greater than or equal to N number of first data block in minimum data amount, then illustrate server to the second data packet into Row verification process be not finished, at this point, server can be directed to each data group in P data group execution step 103~ Step 105 (or 102).

In the embodiment of the present invention, check information is obtained by using the mode of more wheel verifications, server acquisition can be improved The accuracy of the check information arrived, so that the data synchronization process between client device and server is more accurate；Into One step, the data volume that the second wheel verifies corresponding every group of data can be less than the data for the first round verifying corresponding every group of data Amount, that is to say, that the embodiment of the present invention, can be to avoid only with data caused by a wheel verification by way of taking turns verification more Information repeats the technical issues of transmitting, and so as to saving network flow, improves the synchronous efficiency of data.

Step 105, server determines different information according to the check information and the second data packet of M group data, and by difference Information is sent to client device.

Herein, if server is after first time divides, the checking procedure of the second data packet is terminated, then M group data Check information can only include the first check information, perhaps can also only include the second check information or can also include the One check information and the second check information.If the check information of M group data only includes the first check information, illustrate the second data packet In data it is identical as the data in the first data packet；If the check information of M group data only includes the second check information, illustrate Data in two data packets and the data in the first data packet are entirely different；If the check information of M group data includes the first verification Information and the second check information illustrate that a part of data in the second data packet are identical as the data in the first data packet, another Partial data is different from the data in the first data packet.

By taking the second data group as an example, if the check information of the second data group are as follows: 1M is to 300M's in the second data packet Data are different from the first data packet, then data (the i.e. difference of the 1M to 300M in available second data packet of server Information), and the second information is generated according to different information, the second information is sent to client device.Correspondingly, client device The second information can be parsed after receiving the second information, obtain different information, and the second data are updated according to different information Packet.For example, if the data that the different information that client device parses is the 1M to 300M in the second data packet, visitor The data of 1M to 300M in first data packet can be updated to the 1M in the second data packet to by family end equipment The data of 300M.

It should be noted that above-mentioned steps number is only to execute a kind of example of process, do not constitute to each step Execute the restriction of sequencing.

In the above embodiment of the present invention, the second data packet is verified by using the first data packet, can be made Different information is transferred to client device by server, without entire first data packet is sent to client device, thus The loss of network flow can be reduced to avoid duplicate data information is transmitted, improve the synchronous efficiency of data；And the present invention is real The mode for determining the check value of data group in example by using the check value of data block is applied, client device and clothes can be made Being only performed once communication interaction between business device can be completed synchronizing process, without executing multiple communication interaction, so as to subtract The pressure of light network communication, reduces network traffic flow.That is or, data processing method in the embodiment of the present invention can be with It is adapted to the network environment of low bandwidth and flow-sensitive.
