Description
Technical field
The present invention relates to a kind of document retrieval methods, and in particular to a kind of block chained file fragment search method.
Background technique
Data required for the retrieval of current most systems once can only obtain you from a data center, if this
The case where data center breaks down, or is attacked, and similar network application relies on very much backbone network, it may appear that file was lost asks
Topic.Therefore, it is necessary to design a kind of block chained file fragment retrieval device, acquisition when, can be obtained simultaneously from multiple servers
It takes, can be very good shared Various types of data.
Summary of the invention
The technical problem to be solved in the present invention is that providing a kind of block chained file for the above-mentioned deficiency of the prior art
Fragment search method.
The present invention is through the following technical solutions to achieve the above objectives: a kind of block chained file fragment search method, in which:
Include the following steps,
Step 1: source file is obtained according to filename；
Step 2: the source file obtained in step 1 is distributed to file to distribute and be retrieved by the processing of file fragmentation search method
The processing of file fragmentation search method is carried out in device, through file fragmentation search method, treated that file is distributed into storage chains,
It waits and handling in next step；
Step 3: calculating memory node processing, the file in step 2 carried out calculating memory node in storage chains, if
Failure is calculated, source file returns in file fragmentation retrieval device, successfully distributes source file to memory node A if calculating, deposits
Store up node B, memory node C, in memory node D, Chu Jiedian A, memory node B, memory node C, memory node D generate text respectively
Part piece A, file piece B, file piece C, file piece D, file sequence A, file sequence B, file sequence C, file sequence D wait
It handles in next step；
Step 4: step 4: the combination and verification processing of slicing files, by file piece A, file piece B, file in step 3
Piece C, file piece D, file sequence A, file sequence B, file sequence C, file sequence D are handled using file combined method, are formed
Band composition file, then file combined authentication processing is carried out, if file combined authentication processing failure file to be combined is back to file
Fragment is retrieved in device, if file combined authentication is handled successfully, composition file is sent into file fragmentation retrieval device, text is completed
The retrieval of part fragment.
As a further optimization solution of the present invention, the processing of file fragmentation search method successively includes at file fragmentation algorithm
Reason, document retrieval, calculates place chain, the processing of slicing files combined method at file addressing, if file addressing fails, source file is sent
It is back in file fragmentation retrieval device；If file addressing success, carries out document retrieval, obtains file sequence；By resulting file
Chain is handled where sequence and source file are calculated, if calculating failure, source file is returned in file fragmentation retrieval device, if meter
It is counted as function, source file is stored into storage chains.
The beneficial effects of the present invention are:
By file fragmentation algorithm process, the purpose of administration, branch storage is realized.
By file addressing, file is abstracted into special file directory, it can be as the address HTTP when access
Obtain file.
By calculating memory node processing, the target of the storage of decentralization is realized by common recognition mechanism.
Verified by composition file, realize can with operating rate faster, data it is safer.
Detailed description of the invention
Fig. 1 is a kind of flow diagram of block chained file fragment search method of the invention；
Fig. 2 is the specific embodiment flow diagram of Fig. 1.
Specific embodiment
The application is described in further detail with reference to the accompanying drawing, it is necessary to it is indicated herein to be, implement in detail below
Mode is served only for that the application is further detailed, and should not be understood as the limitation to the application protection scope, the field
Technical staff can make some nonessential modifications and adaptations to the application according to above-mentioned application content.
Embodiment 1
A kind of block chained file fragment search method as shown in Figure 1: including the following steps,
Step 1: source file is obtained according to filename；
Step 2: the source file obtained in step 1 is distributed to file to distribute and be retrieved by the processing of file fragmentation search method
The processing of file fragmentation search method is carried out in device, through file fragmentation search method, treated that file is distributed into storage chains,
It waits and handling in next step；
Step 3: calculate memory node processing, will be processed in step 2 after source file generate file in storage chains
In carry out calculating memory node, if calculate failure, source file return to file fragmentation retrieval device in, if calculating source document successfully
Part is distributed into memory node A, memory node B, memory node C, memory node D, Chu Jiedian A, memory node B, memory node
C, memory node D generates file piece A, file piece B, file piece C, file piece D, file sequence A, file sequence B, file sequence respectively
C, file sequence D are arranged, waits and handling in next step；
Step 4: the combination and verification processing of slicing files, by file piece A, file piece B, file piece C, text in step 3
Part piece D, file sequence A, file sequence B, file sequence C, file sequence D are handled using file combined method, form band combination
File, then file combined authentication processing is carried out, if file combined authentication processing failure file to be combined is back to file fragmentation inspection
In rope device, if file combined authentication is handled successfully, composition file is sent into file fragmentation retrieval device, file fragmentation is completed
Retrieval.
