Whole embodiments.Based on the embodiments of the present invention, those skilled in the art institute without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Currently, the cache way that most of client software uses is XML file storage or local file database mode.
Wherein, the mode of XML file storage refers to that client-side data cache saves as XML file, the version that server-side passes through control file
This record realizes the synchronization of Software Version data, when increasing or modifying server-side dictionary data, while updating client software
Version number, client judge whether server-side version and local are consistent, and caching is updated when inconsistent.
But no matter this mode modifies the size of data volume when judging to have update every time, and full dose is all needed to update number
According to cannot achieve the update of incremental data.Also, XML file can be edited in client computer, lead to data safety risk
It is high；Moreover, it judges that the process of version updating is usually to pass through third-party version file to realize, poor fault tolerance, so that
The detection processing of consistency can not be carried out when local cache file is lost but version file is consistent.In addition, the visitor of this mode
Family end data renewal time and server-side update having time are poor, and the data updated within this time difference will lead to client and can not obtain
It takes, also, client updates efficiency speed and depends on data cached size, it is difficult to which solve single file causes when updating caching
Whole system speed decline the problem of.
And local file database mode refers to that client, can using document data bank mode memory buffers file data
Realize incremental mode more new data, if only partial data updates, data, which are updated, only needs the modification of more new increment with downloading
Data.But this mode similarly has that client data updates and server-side updates having time difference, also, client
End data is buffered on user computer, is vulnerable to maliciously distort, and client is caused in turn result in using the data of mistake
Serious traffic issues；Since it relies on local file database, it is also difficult to verify the consistency of dictionary file data；Cause
When client data mistake, can not be repaired by the automatic mode of system there are the problem of.In addition, local file database mode
Round-trip processing data interaction request is needed repeatedly, a large amount of bandwidth waste is caused, meanwhile, client also can not parallel processing table pass
Connection, so that client data renewal speed is slower, reduces the Experience Degree of user.
Based on this, a kind of file updating method provided in an embodiment of the present invention, apparatus and system can be effectively relieved above-mentioned
Technical problem.
For convenient for understanding the present embodiment, first to a kind of file updating method disclosed in the embodiment of the present invention into
Row is discussed in detail.
In a kind of possible embodiment, the embodiment of the invention provides a kind of file updating method, this method applications
In server-side, a kind of flow chart of file updating method as shown in Figure 1, method includes the following steps:
Step S102 receives the first identifier symbol for the first file that client is sent；
Wherein, client is also referred to as user terminal, refers to corresponding with server-side, provides the application journey of local service for client
Therefore sequence usually can all establish specific communication connection with server-side, to guarantee the normal operation of application program.
In general, above-mentioned first file can be the cache file of client, which can be client software
Cache file, such as client software edition data or logon data.Client is starting, or is produced by application program
When certain raw business, it can be interacted with server-side, at this point, available the first file of active client of client is corresponding
First identifier symbol, such as the first identifier symbol of local cache file, are then sent to server-side for first identifier symbol.
Wherein, above-mentioned first identifier symbol is usually that client is based on active client file or cache file generation
Identifier, also, the first identifier symbol in the embodiment of the present invention is usually MD5 value, for example, the MD5 value of local cache file, tool
Body, MD5 (Message-Digest Algorithm) value is a kind of Cryptographic Hash Function being widely used, and be can produce out
The hashed value (hash value) of one 128 (16 byte), for ensuring that information transmission is complete consistent.Also, the life of MD5 value
Algorithm can be converted at process by irreversible character string, generate this by local cache file as a big text information
The unique MD5 informative abstract of ground cache file, the uniqueness of the MD5 value can make server-side effectively judge client software version
Whether notebook data has update.Specifically deterministic process can be realized by following steps S104.
Step S104, accords with according to first identifier and the corresponding relationship between pre-stored the file information and identifier judges
Whether the first file has update；
In actual use, server-side can in advance save the file information of client, record corresponding client
The file information and the corresponding identifier of this document information etc. are held, in order in the first identifier for receiving client transmission
Fu Shi, judges whether the first file of client has update.
For example, when first file is client local cache file, and the local cache file is client software version
When notebook data, the file information that server-side pre-saves can be the information of client software edition data, such as latest edition number
According to, and relative to more new data etc. of the latest edition data, also, for each client software version, there is it
Corresponding identifier, between the first identifier that server-side is sent according to client and the file information and identifier
Corresponding relationship judge whether the first file has update.
Step S106 sends the more new data of the first file in the case where judging result is that the first file has update
To client, so that client is updated the first file according to more new data.
A kind of file updating method provided in an embodiment of the present invention, apparatus and system can be sent receive client
The first file first identifier symbol when, according to first identifier symbol pre-stored the file information and identifier between it is corresponding
Relationship judges that the first identifier accords with whether corresponding first file has update, and when there is update by the more new data of the first file
It is sent to client, so that client is updated current first file according to more new data, is accorded with above by first identifier
Judge whether that the process updated can effectively judge the consistency of current first file and server-side, and then realizes client first
Effective update of file not only increases client data and updates efficiency, it helps improves the Experience Degree of user.
In actual use, using above-mentioned first file as client local cache file, and, which includes
It is illustrated for client software edition data, at this point, corresponding between above-mentioned pre-stored the file information and identifier
Relationship generally includes: client software version number, the more new data of client software edition data and the corresponding relationship of identifier,
Therefore, file updating method described in the embodiment of the present invention further include server-side establish it is corresponding between the file information and identifier
The process of relationship, the process is usually according to the corresponding pass between first identifier symbol and pre-stored the file information and identifier
System judges whether the first file has progress before update, and specifically, which generally includes following steps:
(1) incremental data of file is received；
Wherein, if above-mentioned first file is client local cache file, and, which includes client
Software Version data, at this point, the increase data can be the incremental data of client software edition data；Specifically, the increment
Data can be client software developer be directed to active client software provide more new data, as processing business and updates data,
Function optimization data etc..
(2) identifier of above-mentioned file is generated according to incremental data；
(3) by the file information associated storage of identifier and file, above-mentioned corresponding relationship is obtained.
For ease of understanding, equally illustrate so that increased data are client software edition datas as an example, specifically, server-side
After receiving incremental data, the corresponding client software version number of the incremental data can be extracted, in general, client software version
It number may include that the principal mark of client software version is known and the sub-mark of client software version；The corresponding visitor of different incremental datas
Principal mark in the software version number of family end is sensible same, and sub-mark is different；For example, version V4.0.1, therein 4.0 can be known with principal mark,
Last number 1 indicates sub-mark；The corresponding identifier of different clients software version number is different, for example, V4.0.1 pairs
The identifier answered is first identifier symbol, if V4.0.1 version updating, there is new incremental data, after being updated to V4.0.2 version,
The file information of the file information and V4.0.1 version comprising incremental data is different at this time, so that the file of V4.0.2 version
The identifier of information and the identifier of the file information of V4.0.1 version are different.Therefore, it can be saved in server-side each
The identifier of the corresponding the file information of version and the version file information, so establish above-mentioned the file information and identifier it
Between corresponding relationship.
When specific implementation, above-mentioned identifier generallys use MD5 value, the uniqueness of MD5 value, so that the text of above-mentioned different editions
The corresponding MD5 value of part information is the unique information for indicating the file information.Therefore, server-side can judge according to above-mentioned corresponding relationship
First identifier accords with whether corresponding first file has update.
Based on above-mentioned corresponding relationship, above-mentioned steps S104 can be realized by process once: according to corresponding relationship search with
First identifier accords with corresponding first the file information；The second identifier of the first file is obtained according to the first the file information and corresponding relationship
Symbol；Judge whether first identifier symbol is accorded with second identifier consistent；It is that first identifier symbol is consistent with second identifier symbol in judging result
In the case where, determine that the first file has update.
In actual use, the corresponding relationship between above-mentioned the file information and identifier can be presented in table form,
When server-side receives first identifier symbol, the first identifier can be searched in the table and accords with corresponding first the file information, into
And the corresponding second identifier symbol of the first the file information is found, since second identifier symbol is usually current first the file information
Therefore newest identifier can accord with according to the second identifier and find corresponding more new data.
Based on this, the embodiment of the invention also provides another file updating methods, to the judgement renewal process of server-side
It is described.In order to make it easy to understand, table 1 shows a kind of corresponding relationship of form, as shown in table 1:
Table 1
Specifically, it is illustrated by taking above-mentioned table 1 as an example.The flow chart of another file updating method as shown in Figure 2, with
The following steps are included:
Step S202 receives the first identifier symbol for the first file that client is sent；
Step S204 searches the first the file information corresponding with first identifier symbol according to corresponding relationship；
It, can be according to table 1 after server-side receives MD1 by taking the received first identifier symbol of server-side is MD1 as an example
Corresponding relationship find the corresponding first the file information V1.0.1 of MD1, which is usually the version of current file information
Number.
Step S206 is accorded with according to the second identifier that the first the file information and corresponding relationship obtain the first file；Judge first
Whether identifier accords with consistent with second identifier；If so, terminating；If not, executing step S208；
It specifically, as shown in Table 1, can after the first the file information V1.0.1 that server side searches are MD1 to first identifier symbol
, but V1.0.2 that sub-mark different sensible same with the principal mark of V1.0.1 is found with the corresponding relationship according to shown in table 1, and
The corresponding second identifier of V1.0.2 accords with MD2, since MD2 is different from MD1, server-side may determine that first identifier at this time
Symbol accords with inconsistent with second identifier.Therefore, step S208 can be continued to execute.
If the received first identifier symbol of server-side is MD3, and server-side is right according to shown in table 1 in step S202
It should be related to that finding the current corresponding newest identifier of MD3 corresponding version number V2.0.1 and version number V2.0.1 is also
MD3.At this point, server-side may determine that first identifier symbol is consistent with second identifier symbol at this time, therefore, server-side can be tied
The more new technological process of Shu Dangqian.
Step S208 determines that the first file has update；
Step S210 obtains second identifier and accords with corresponding more new data；
Specifically, which is the data for formed after packing storage to the incremental data of the first file, in general,
For the ease of getting the more new data, it can be associated with the more new data of packing storage in the above correspondence relationship.
It, can be according to above-mentioned after server-side receives MD1 equally by taking the received first identifier symbol of server-side is MD1 as an example
Corresponding relationship shown in table 1 finds corresponding V1.0.1, and gets the corresponding newest identifier (second identifier of V1.0.1
Symbol) MD2, so that it is available corresponding relative to first identifier symbol MD1 to the corresponding second identifier symbol MD2 of second identifier symbol MD2
More new data Data1, then execute step S212.
Second identifier is accorded with corresponding more new data and is sent to client by step S212；
In general, related protocol, such as Protocol Buffer agreement can be used after client receives more new data,
Data sequence will be updated and turn to cache file, meanwhile, the corresponding new MD5 value (identifier) of cache file is submitted to clothes again
It is engaged in end, being continued to judge whether the current client software edition data of client is newest cache file by server-side.Wherein,
The mode that update data sequence is turned to cache file in client, can be easy to implement the communication in server-side and client
Journey, specifically, client can such as carry out data operating after the update Data Serialization received to more new data
It updates, updated MD5 value is submitted to server-side etc. again, further, the sequence that server-side can send client again
After changing data progress unserializing, then subsequent operation is carried out, the specific mode that serializes can be realized with reference to the relevant technologies, this hair
Bright embodiment is not limited this.
It is above-mentioned by the way of Data Serialization, it can be ensured that the storages of data efficiently and formats, and guarantees more new data
Preservation and load efficiency.Specifically, since the more new data is usually soft relative to the corresponding client of first identifier symbol
The more new data of part edition data, therefore, when client carries out more active client Software Version data according to more new data
The identifier (e.g., MD5 value) obtained after new is that the newest identifier of client software corresponding with server version number is
It is consistent.
But, it is contemplated that in client renewal process, also can presence service end receive client software version simultaneously
The case where incremental data of data, therefore, file updating method provided in an embodiment of the present invention further include that client verifies again
The process of active client Software Version data verifies local cache file again, avoids current cache file may not
It is newest cache file.Specifically, the process verified again can be realized by following step S214~step S220.
Step S214 receives the third identifier that client is sent；
Wherein, which is the identifier for the file information that client is generated according to above-mentioned more new data, is updated
The file information afterwards generally includes original the file information, and more new data.
Specifically, which is also possible to MD5 value.
Step S216 judges whether third identifier is accorded with second identifier consistent；If so, executing step S220；If
It is no, execute step S218；
Second identifier is accorded with corresponding more new data and is sent to client, return step S214 by step S218；
Step S220 determines that the first file updates and completes.
The above-mentioned process verified again to client software edition data, can be effectively ensured active client software version
Data are the data of recent renewal.It is also possible to realize the synchronized update of the data at client and server-side, realize parallel
Processing, saves renewal time when individually carrying out data update to server-side and client, improves the efficiency of processing.
In addition, exception, or the packet loss event due to caused by network problem are downloaded for more new data, by verifying again
Process, client, which also can be carried out, automatically corrects reparation, and when file modification or damage to ensure more new data can synchronized update.
Further, if the first identifier symbol that client is sent is null value, that is, in step S102 or S202, server-side
In the case where the data of the first identifier symbol received are null value, the first file is sent to client.Wherein, first identifier accords with
For null value may be since the case where active client Software Version data is emptied or client is formatted, is caused,
At this point, server-side can send the first file, such as whole client software edition datas to client, also, service at this time
Hold the first file sent, the corresponding data of usually newest client software version number, when ensuring file modification or damage
It can synchronized update.
In alternatively possible embodiment, the embodiment of the invention also provides another file updating method, the party
Method is applied to client, the flow chart of another file updating method as shown in Figure 3, method includes the following steps:
Step S302 sends the corresponding first identifier symbol of the first file to server-side, so that server-side is according to first identifier
Symbol and the corresponding relationship between pre-stored the file information and identifier judge whether the first file has update；
Step S304 receives the more new data for the first file that server-side returns in the case where the first file has update；
Step S306 is updated the first file according to more new data.
Further, after client is updated the first file according to more new data, the above method further include: according to
More new data generates the third identifier of the first file, third identifier is sent to server-side, so that server-side determines first
Whether file updates completion, realizes the process verified again to the first file (e.g., data cached etc.) of client.
In addition, being carried out according to more new data to the first file to improve client to the loading efficiency of more new data
After update, the above method further includes the Memory Mapping File that more new data is saved in client, in order to which client is to more
New data is loaded.Specifically, the more new data received for client, can further using memory formatted file into
Row storage, for example, client more can will be stored as Memory Mapping File by new data, leads to the application program in client
It crosses memory pointer to access to the file of more new data, accelerates treatment effeciency.
To sum up, file updating method provided in an embodiment of the present invention has the advantages that
(1) identifier of file has uniqueness, as first identifier symbol, second identifier symbol or third identifier use
The form of MD5 value, it can be ensured that can synchronized update when file modification or damage；
(2) file uses Data Serialization mode, it is ensured that the storage of data is efficient and formats, and guarantees data cached preservation
