Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is carried out
Clearly and completely describe, it is clear that described embodiment is only some embodiments of the present application, and
It is not all, of embodiment.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of the application protection.
It will be appreciated by those skilled in the art that the application scenarios first introducing the application for convenience.The application master
End side to be applied to and server side, can carry out uploading of file between end side and server side
And download.The concrete execution process of the application is described in detail below.
First, the detailed process of transmitting file on terminal lateral server side is introduced.Terminal can be to server
Upload multiple file successively, owing to terminal is consistent to the processing procedure of each file with server, therefore,
The present embodiment is described in detail only for the execution process of a pending file.The execution of other file
Process is consistent with the execution of pending file, does not repeats them here.
This application provides a kind of data uploading method, be applied to end side.As it is shown in figure 1, specifically wrap
Include following steps:
Step S101: pending file is cut into several data blocks；Wherein, each data block is corresponding
In a data block identifier.
The most pending file transmits, it is possible to preferably pending file is carried out duplicate removal process and (goes
Process except the data block repeated) pending device file would generally be cut into several data blocks.In order to
The each data block of convenient identification, can be that each data block distributes a data block identifier.
Illustrate in order to make it easy to understand, existing: assume that by pending file cutting be 10 parts, then can obtain
To data block 1, data block 2 ... data block 10.It is understood that in actual applications, counted
It is far longer than 10 according to number of blocks, is only illustrative citing herein.
Step S102: build at least one packet based on several data blocks described；Wherein, every number
According to bag corresponding to a package identification, and, at least one packet comprises at least two data block.
Due to pending file, to be cut into data block quantity more, if transmitting each data block one by one, then
Need between terminal and server, between server and storage device, carry out many data transfer.In order to drop
Low server receives the number of times of data block and reduces the server number of times to storage device transmission data block,
The application some data blocks based on pending file build at least one packet.
The process that based on several data block build at least one packet is described in detail below.This process can
There to be two kinds of implementations:
The first implementation: comprise fixed qty data block by a packet and build packet.
Technical staff can arrange a predetermined number in advance in the memory space of terminal, and terminal is building
Predetermined number can be obtained in memory space during packet.Then, terminal is to predetermined number and pending
The data count amount of file is analyzed processing, and obtains data packet number and data that each packet comprises
Number of blocks.
The detailed process determining data packet number and data number of blocks can be: terminal calculates pending file
The total quantity of the data block being cut into and the quotient and the remainder of predetermined number.If remainder is zero, then business is made
For needing to build the quantity of packet, and, each packet comprises the data block of predetermined number.If it is remaining
Number non-zero, then the data packet number that business+1 builds as needs, and, data comprise remainder number
According to block, other packet comprises the data block of predetermined number.
Such as, pending file is cut into 10 packets.Assume that fixed data number of blocks is 5, then
The result being divided by of 10 and 5 is 2.That is, it needs to build 2 packets.Assume fixed data number of blocks
Being 3,10 and 3 to be divided by that to obtain business be 3, remainder is 1.It is possible to build 4 packets, wherein
3 packets include that 3 data blocks, a packet include 1 data block.It is, of course, also possible to build
3 packets, two of which packet all includes that 3 data blocks, a packet include 4 data blocks.
Obtaining data packet number in first way and after data block quantity that each packet comprises,
Then can build packet.As a example by the process building packet A, terminal is built at least one data
The process of bag illustrates: determine data block quantity A corresponding for packet A, in pending file cutting
After each data block in select data block quantity A data block, then by these data blocks form data
Bag.The building process of other packet can participate in the building process of packet A, is repeating no more.When
So, determine that the data block quantity of data packet number and each packet can also use alternate manner, at this
Will not enumerate.
The second implementation: comprise non-quantitative data block by a packet and build packet.
Terminal can arbitrarily determine data packet number, and the most each packet comprises variable amount of data block.
In order to have beneficial effect than only transmitting independent data block in prior art, data packet number is less than data block
Total quantity.So so that at least a packet comprise at least two data block.Therefore, phase
For individually transmission data block, it is possible to reduce the overall transfer number of times of pending file.
After building each packet, in order to distinguish each packet, can with each allocation of packets not
Same package identification.
Step S103: upload the packet of described pending file to server.
After packet has built, packet can be uploaded onto the server by terminal one by one.By servicing
Device stores.After pending files passe to server, terminal can delete treating of self storage
Process file, in order to increase the memory space of self.
Above-mentioned processing procedure does not increases the execution process of terminal duplicate removal, if directly all data blocks all being sent
To server, then can increase the data volume of transmission.Therefore, the application provides again a kind of data uploading method,
Increase the processing procedure of terminal duplicate removal.As in figure 2 it is shown, described method specifically includes following steps:
Step S201: pending file is cut into several data blocks；Wherein, each data block is corresponding
In a data block identifier.
Step S202: data content based on each data block verifies, and obtains the school of each data block
Test value.
Each data block includes two parts: header portion and data content portion.Header portion is used for depositing
Storing up some marks, data content portion is used for storing concrete data.In order to authentication server has been deposited
Contain this data block, then the data content of each data block of pending file is verified, obtain school
Test value.Check value can be as the data block identifier of a data block.Verification calculation can use Kazakhstan
Uncommon algorithm or other algorithm.
Step S203: check value based on described each data block and the school of described server data with existing block
Test value, determine the data block set to be uploaded of described pending file.
Terminal is previously stored with the check value of data with existing block on server, or, terminal can be from service
The data block identifier of data with existing block is obtained in real time on device.Owing to check value can uniquely represent data
Block, therefore, if the check value of two data blocks, two data blocks are identical, otherwise represent two data blocks
Different.
Therefore, terminal is for each data block, by the check value of this data block and server data with existing block
Check value contrast, if both are consistent, then it represents that server has stored this data block, pending literary composition
This data block in part then need not upload onto the server.If both are inconsistent, then it represents that server does not stores
This data block, this data block in pending file needs to upload onto the server, for the ease of address, will
This data block is referred to as data block to be uploaded.
It is right by the check value of each data block and the check value of described server data with existing block are carried out
Ratio, it may be determined that data block set to be uploaded.Wherein, data block set to be uploaded includes i number to be uploaded
According to block, and, 0≤i≤N, N are the total quantity that described pending file is cut into data block.
That is, if in file to be uploaded, each data block stores the most, data block the most to be uploaded
Set includes 0 data block to be uploaded.If all data blocks are not the most all deposited in file to be uploaded
Storage, data block set the most to be uploaded includes N number of data block to be uploaded.N is described pending file cutting
Become the total quantity of data block.
Step S204: build at least one packet based on described data block set to be uploaded；Wherein, often
Individual packet corresponds to a package identification, and, at least one packet comprises at least two data
Block.The execution process of this step may refer to step S102, does not repeats them here.
Step S205: upload the packet of described pending file to server.
In terminal after duplicate removal processes, no longer can send existing data block on server to server,
Therefore, it can reduce terminal to server and upload the quantity of data block, such that it is able to reduce server process
The quantity of data block.
In the embodiment shown in Fig. 1 or Fig. 2, for the ease of the file of the pending file of server identification
Information, terminal can also carry out following process.As it is shown on figure 3, specifically include:
Step S301: generate the fileinfo of described pending file；Wherein, described fileinfo includes:
The data block of all data blocks that the file identification of described pending file is corresponding with described pending file
Mark and the Rankine-Hugoniot relations of all data block identifier corresponding with described pending file.
The terminal pending file of server identification for convenience, therefore, by the identification information of pending file,
Pending file is cut into the mark of all data blocks, and, all data block identifier of pending file
Rankine-Hugoniot relations.
Additionally, fileinfo can also include the package identification of pending each packet of file.
Step S302: upload described fileinfo to described server.
When the main purpose of fileinfo is, server stores the relevant information of pending file, in order to terminal
When downloading pending file, pending file can be downloaded based on the relevant information of pending file.
The detailed process downloading pending file will be described in detail in subsequent embodiment, not repeat them here.
From above-mentioned processing procedure, can be seen that the application has the advantages that
Several data blocks of pending file are configured to multiple packet by the application terminal, and terminal is with number
Data block is sent to server according to the form of bag.Owing to each packet has multiple data block, so,
Transmission of data packets can transmit multiple data block, once transmit one compared to prior art
For data block, improve the data volume of transmission.Therefore, the application with the form of packet to server
Send data block, server reception number of operations can be greatly reduced and also reduce server output function number of times；
And then reduce storage device input operation number of times.Therefore, the application can improve the handling capacity of data and drop
The upper transfer efficiency of low file.
Embodiment shown in Fig. 1 is the execution process of terminal in data uploading method, is described below and Fig. 1
The processing procedure of the server side that shown embodiment is corresponding.As shown in Figure 4, this application provides one
Data uploading method, is applied to server, specifically includes following steps:
Step S401: receive each packet that terminal is uploaded；Wherein, each packet is that terminal is being incited somebody to action
At least one set up after pending file is cut into several data blocks, based on several data blocks described
A packet in packet；Each data block corresponds to a data block identifier, each packet pair
Ying Yuyi package identification, and, at least one packet comprises at least two data block.
Server receives terminal upload data bag, and the processing procedure of packet is shown in Fig. 1 and Fig. 2
Embodiment is described in detail, does not repeats them here.
Step S402: described each packet is stored to storage device.
Server after receiving the packet of data, by packet global storage to storage device.
Being stored by packet after storage device, server also can perform subsequent treatment mistake to packet
Journey, in order to use during terminal downloads packet.The following detailed description of server once storage packet it
After processing procedure.As it is shown in figure 5, specifically include following steps:
Step S501: obtain each packet storage address realm in storage device.
Owing to a packet includes one or more data block, therefore, packet is in storage device
There is a storage address realm.Such as, occupy as a example by a storage address by a packet, it is assumed that
One packet has 16 data blocks, then storage address realm can be 0010H～001FH.Wherein,
0010H is the initial memory address of packet, and 001FH is the end storage address of packet.Middle tool
There are 16 storage addresses, each storage address correspondence one data block of storage.
Step S502: by packet mark corresponding with each packet for the storage address realm of each packet
Know correspondence to store to meta data server.
Server learns the storage position in storage device of each packet for convenience, and server can
With the storage of each packet, address realm is corresponding with the package identification of each packet stores to metadata
In server.Meta data server can be server self in this application, or outside server
Other server, does not limits at this.
Step S503: obtain each data block in each packet and relatively store address and the number of each data block
According to block identification.
Comprising one or more data block in each packet, each data block stores in the address of packet
In the range of all have a relative storage address.Such as, continuity step S501 is illustrated, if storage address model
Enclose for 0010H～001FH.So, the relatively storage address of data block can be 0011H, 0012H,
0013H……0019H、001AH、001BH……001FH。
Step S504: by the package identification of packet belonging to described each data block, relatively storage address with
And data block identifier correspondence stores to described meta data server.
For the ease of the follow-up packet learnt belonging to each data block of server, each data block is in data
Bag stores address relatively, can set up data block identifier, relatively storage address and package identification it
Between corresponding relation.
By the embodiment shown in Fig. 5, then can set up package identification and number in meta data server
According to the corresponding relation between bag storage address realm, it is also possible to set up each data block in a packet
Relatively store the corresponding relation between address, package identification and data block identifier.
In order to understand the corresponding relation of the step shown in explanatory diagram 5, continue the citing of step S501 below,
Corresponding relation pointed by Fig. 5 embodiment is illustrated.See table 1:
Table 1
By the embodiment shown in Fig. 3, terminal can send fileinfo to server.So, exist
Terminal to server sends after fileinfo, and as shown in Figure 6, server can also carry out following process:
Step S601: obtain the fileinfo of the described pending file that terminal is uploaded；Wherein, described literary composition
Part information includes: all numbers that the file identification of described pending file is corresponding with described pending file
Close according to the data block identifier of block and the arrangement of all data block identifier corresponding with described pending file
System.
Step S602: by described file information storage to meta data server.
In order to represent fileinfo in detail, show fileinfo in table form.Assume pending file
Being cut into N number of data block and see table 2, for this packet, fileinfo specifically includes following
Content:
Table 2
Embodiment shown in Fig. 1～Fig. 6 is, the execution process uploaded for data between terminal and server,
Process that terminal and server between data download is described below.
As it is shown in fig. 7, this application provides a kind of data download method, it is applied to terminal.Described method
Specifically include following steps:
Step S701: send the download request obtaining pending file to server.
Terminal can generate the download request obtaining pending file, and request of downloading is corresponding to described pending
The data block identifier of each data block in file.Such as, the request of downloading can include the literary composition of pending file
Part identifies.The download comprising the file identification of pending file is asked to send to server by terminal.
Step S702: receive each data block that described server sends.
The download request obtaining pending file is received at server, and according to obtaining under pending file
After the request of load obtains each data block in memory space, just by each number corresponding with pending file
Sending to terminal according to block, terminal then can receive each data block of pending server.
Step S703: each data chunk is synthesized described pending file.
This step is when specifically performing, and terminal may determine that putting in order of each data block described；By institute
State the combination that puts in order each data block described, it is thus achieved that described pending file.
Owing to server is after terminal sends each data block, each data block is out of order arrangement, therefore,
Terminal needs to put in order, by each data chunk according to each data block is original in pending file
Pending file just can be obtained after conjunction.
Wherein it is determined that putting in order of each data block can have two kinds of processing modes:
The first processing mode: obtain from server and put in order.
Knowable to the embodiment shown in Fig. 6, meta data server storage has the arrangement of all data block identifier
Relation, therefore, server can be when sending each data block, by all for pending file data blocks
Putting in order of mark sends the most in the lump to terminal.
The second processing mode: obtain from terminal self and put in order.
Knowable to the embodiment shown in Fig. 3, terminal can also obtain the mark of all data blocks of pending file
That knows puts in order, and stores to terminal self.Now terminal can obtain in the memory space of self
Putting in order of the mark of all data blocks of pending file.
