Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to keep the above objects, features and advantages of the present invention more obvious and easy to understand, with reference to the accompanying drawing and specifically
The present invention is described in further detail for embodiment.
As shown in Figure 1, being a kind of flow chart of data buffer storage processing method provided in an embodiment of the present invention, this method is main
The realization process of this method is described from the angle of client, the present embodiment mainly retouches data cached storing process
It states, can specifically include：
Step S101 detects the data volume to memory buffers data；
Step S102 waits for that memory buffers data are compressed to this, obtains wait store when the data volume reaches preset threshold
Compressed file；
In practical applications, client receive it is a large amount of it is data cached after, can use compression algorithm to a large amount of caching numbers
According to compression processing is carried out, the embodiment of the present invention is not construed as limiting the content of the compression algorithm, can be according to different compression algorithms
Performance and compression ratio flexible choice, specific implementation process are no longer described in detail one by one herein.
Step S103 treats storage compressed file and is encrypted, obtains corresponding storage file；
It optionally,, can be with before treating storage compressed file and being encrypted in order to guarantee the accuracy of storing data
It first treats storage compressed file and carries out accuracy detection, when to read respective cache data from now on, can judge to be read accordingly
The problems such as whether access evidence is tampered,
Therefore, before step S103, the embodiment of the present invention can treat storage compressed file and be verified, for example pass through
MD (Message Digest Algorithm, message digest algorithm) 5, MD3 scheduling algorithm realize verification, wherein when to caching number
According to the higher situation of accuracy requirement under, MD3 algorithm can be used and verified, however, it is not limited to this.
MD5 and MD3 can realize the verification for treating storage compressed file, security level is higher, phase by calculating hash value
Corresponding consumption resource is also more, and therefore, the accuracy requirement for treating memory buffers data is not in very high application, can be with
It is one group according to two bytes for needed memory buffers data to add up, will be cumulative and as the first check value, and store
To memory buffers data end in the compressed file to be stored, such as：Data are 0,x11 22 33 44, in addition the first verification
Data after value are：0x11 22 33 44 44 66.
It is optional, in embodiments of the present invention, can periodically to cached it is each it is data cached verify, once verification
Obtained check value is different from initial check value (i.e. the first check value), it is believed that the data cached appearance during caching
Problem can force to control the failure of its cache tag position, avoid it is subsequent unnecessary reading behavior is carried out to invalid cache data,
Improve data reading performance using redundancy.
In practical applications, for compressed data cached i.e. compressed file to be stored to be stored, if writing direct
To the disk storage of terminal device, it is easy to by other people decompilings, to steal user data.Therefore, slow in order to improve data

(however, it is not limited to this, can be other data) carries out one cycle exclusive or, then by obtained result and checked data
Circulation exclusive or is carried out, exclusive or result is saved to disk.Assuming that the pseudo-code of user be 0x11001110, with 0x55 exclusive or after can
To obtain 01010111, exclusive or can be carried out with above-mentioned compressed file to be stored by 01010111 later.
Wherein, user's pseudo-code can obtain the unique identification of the user after logging in client and completing registration, therefore, no
User's pseudo-code with user is difference, ensure that the uniqueness for client key, in practical applications, moreover, the user
Pseudo-code can obtain after user logs in client, avoid and the case where key loss can not decrypt occur.
Step S104 caches the storage file, and the cache tag position of the storage file after caching is arranged.
In embodiments of the present invention, therefore the disk realization that terminal device can be used is receiving the caching of data
After storage file after encryption, the disk that can send it to terminal device is stored, meanwhile, to this caching
Cache tag position is arranged in storage file, indicates whether disk currently stores storage file by the cache tag position, and
Whether the storage file of storage is effective, for example, cache tag position is data cached effective in 1 expression respective stored file；
If cache tag position can indicate data cached invalid in respective stored file for 0, it is generally the case that for invalid cache number
According to that can not read again, in order to save disk storage space, can be deleted.
Wherein, the valid cache data of the present embodiment can refer to that this is data cached in itself without mistake, can normally be read
It takes；And invalid cache data can refer to that this is data cached wrong in itself, such as data are imperfect, messy code, lead to the caching number
According to can not normally read, or the data read are imperfect, messy code or cache-time time-out etc..
In the present embodiment practical application, after obtaining storage file in the manner described above, it is cached to terminal device
It is usually effective in disk, therefore, when its cache tag position is arranged, the effective caching of expression can be set to
Flag bit, such as " 1 " expression respective cache data are effective, " 0 " indicates that respective cache data invalid, the present embodiment can will be cached to
The cache tag position 1 of the storage file of terminal device disk, however, it is not limited to this.
Optionally, the embodiment of the present invention can the preset data cached longest cache-time for allowing disk storage
Section, is denoted as caching effective period of time, but do not limit its specific value, in this way, for buffered each storage file, Ke Yishi
When or periodically detect the current cache time section of each storage file, so that in the caching of certain storage file time-out, (i.e. it is worked as
Preceding cache-time section is more than caching effective period of time), the cache tag position of the adjustable storage file is flag bit, to make
Data cached failure in the storage file, it is subsequent to be further continued for reading that this is data cached, in this way, subsequent reading cache data
When, it can be based on its corresponding cache tag position, valid cache data can reliably and be quickly read, avoid to invalid cache
The read operation of data.
In conclusion when needing to largely when memory buffers data cache, the embodiment of the present invention is in order to realize pair
To the fast cache of memory buffers data, and data cached safety is improved, it can be first to it largely to memory buffers data
It is compressed, then obtained compressed file to be stored is encrypted, later, obtained storage file is cached,
The cache tag position of the storage file is set simultaneously, and whether the storage file to indicate caching is effective, so as to quick accordingly from now on
Whether judgement currently stores effective target cache data, and since the storage file of caching is all encryption, avoids illegal
User to data cached unauthorized theft, distort, substantially increase data cached storage security.
As shown in Fig. 2, for the flow chart of another data buffer storage processing method provided in an embodiment of the present invention, this method master
If being based on above-mentioned storing process, data cached reading process is described, can specifically include following steps：
Step S201, response buffer data read request；
Wherein, which is used for the target cache data for requesting to read the characterization target cache page,
That is the present embodiment can be according to data cached read requests, when caching the target cache page to obtain, real cache
Data cached, will pass through load, this is data cached, exports the target cache page.
In practical applications, (the application installed on terminal device of any client in user's using terminal equipment
Program APP or Web page application program) during, it will usually it is operated in the operation interface of the client, into various pages
Face, and the output for the page, usually by loading page data, such as text, image, video, the template data in the page
Etc., to guarantee the normal output of the page.

Execute step S204；
Wherein, target storage file is the storage file comprising target cache data, can be marked by its corresponding caching
Will position indicates whether it is effective.
In practical applications, it usually will be installed multiple client in subscriber terminal equipment, what each client operation generated
Various data (such as various historical datas, data cached), it will usually storage is associated with the client, specifically, terminal
Corresponding data buffer storage space can be set for each client in equipment, be generated for storing in the client operational process
It is data cached.Therefore, user uses some client, and wants to enter into the target cache page (i.e. times of client output
One page) when, it is slow can to search target corresponding with the target cache page from the corresponding data buffer storage space of the client
Deposit data.
Wherein, above-mentioned implementation is referred to the data cached storage mode of each client about data buffer storage space
The description of example corresponding portion, i.e. compression and encryption, for the different target cache pages, corresponding target cache data are past
Toward difference, therefore, in order to export the target cache page, the content that the data cached read requests of generation include will be different, this
Embodiment is no longer described in detail one by one herein.
Based on to data cached read requests parsing result, determining this needs to read which corresponding target cache page
After target cache data, it can inquire whether it is currently stored with the target cache number first from the disk of memory buffers data
According to, such as above-mentioned analysis, due to the spatial cache of disk be not to data cached cache-time it is unlimited, if data cached
Cache-time section be more than preset caching effective period of time, this it is data cached will be invalid, even if being read, be not available yet, because
This reduces page response performance, the target cache that the present embodiment is inquired in reading in order to avoid reading invalid cache data
Before data, whether effective, to guarantee that client can reliably export the target cache page if can first detect the target cache data
Face.
Wherein, the data storage implementation example as described in above-mentioned text can be set in memory buffers data comprising the caching
The cache tag position of the storage file of data indicates that this is data cached whether effectively by the cache tag position, therefore, this hair
Whether the cache tag position that bright embodiment can detecte the storage file comprising target cache data inquired is effective marker
Position, to determine whether the disk of terminal device is currently stored with comprising target cache data and effective target storage file, tool
The present embodiment does not limit for body detection process.
Step S203, load initialization is data cached, exports the target cache page；
Wherein, it is initial it is data cached can be built-in data cached when publication, may be used to user and open for the first time
It is loaded when loaded and displayed or user can not obtain data failure in data and caching from third party when dynamic.The present invention is implemented
Example is not construed as limiting the initial data cached content for including.
Optionally, in embodiments of the present invention, it determines slow currently without the effective target for caching the corresponding target cache page
Deposit data can initiate data acquisition request to background server, which can carry the target cache page
Identification information and client is fed back to, so that client so that it is data cached to initialize background server acquisition accordingly
It loads that the initialization is data cached, the output of target cache data is realized, even if in this way, user is initially opened target cache page
Face also can reliably export, but be not limited to this kind of implementation described herein.
The target storage file is decrypted in step S204；
In embodiments of the present invention, it can be compressed to compressed wait store based in above-mentioned data cached storing process
The target storage file (it is usually the presence of compressed file form) inquired is decrypted in the Encryption Algorithm that file uses,
