Specific embodiment
Below in conjunction with attached drawing, an exemplary embodiment of the present invention will be described, including the various of the embodiment of the present invention
Details should think them only exemplary to help understanding.Therefore, those of ordinary skill in the art should recognize
It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
The core of technical solution of the present invention is: providing " the data manipulation realized based on mapping object for user
Layer ", mapping object expose " additions and deletions, which change, looks into " operation interface of data outward, and no longer directly access is locally stored user
Data in localStorage, but the data in localStorage are accessed indirectly by these operation interfaces.Therefore,
This " data operation layer " shields the actual data manipulation of bottom.The present invention is based on this " data operation layers ", may be implemented
The extension functions such as isolation, the verification of data expired time of different business data.It, can be by using retouching based on object mapping mechanism
The metadata mapped between object and data storage is stated, object is persisted to local data memory space automatically.In the following, to this
Two key points of the technical solution of invention are described respectively.
First is that " data operation layer ", currently, only there are two the stages for the data manipulation of client: user is touched by terminal applies
Data manipulation is sent out, localStorage receives message and corresponding operation is carried out to data.The present invention the two above stage it
Between, increase the stage of one " data operation layer " newly: firstly, user is grasped by the data that various events trigger " additions and deletions, which change, looks into "
Make, and transmits the data of practical operation to " data operation layer "；Then, " data operation layer " receives the data manipulation message of user
And it is packaged according to client environment using data manipulation message of the different data encapsulation methods to user, and will be after encapsulation
Message transmission to bottom localStorage；Finally, localStorage carries out actual data storage or returns to number
According to；The data of return are also needed through " data operation layer ", from " data operation layer " check data availability and then to
User's returned data.
Second is that " mapping object ", mapping object essence is a common Javascript object.But the present invention uses
This method of Object.defineProperty has redefined the setter method of this object properties (for being arranged or depositing
Store up data) and getter method (for obtaining or searching data), it is added in setter method to localStorage and is sent out
The code for sending data operation information, the no longer attribute value of returning an object value itself in getter method, but return
Value in localStorage.In this way, mapping object corresponding will go to grasp when user is when operating this mapping object
Make localStorage.Mapping object keeps apart user and actual storage container (local storage space), and user is not
It is concerned about how actual data store, it is only necessary to pass through code: var jshop=Storage (' jshop '), it can be right
Data in local data space jshop carry out the operation of " additions and deletions, which change, looks into ".At the same time it can also expand on mapping object
Put on display NameSpace and expired time function, with solve localStorage can not be isolated different business data and not can from
The problem of defining expired time.
There can be multiple business on the usual same page, such as: certain part commodity is paid close attention to, some shop is collected, obtains shop
The different business such as gift bag can be located on the same page.Confounding of variable between business or duplication of name in order to prevent, different industry
Business data are preferably formed with independent " memory space ".Isolation for the data variable of different business, there is no browser branch at present
It holds.In order to solve this problem, the present invention is the data of different business, by adding different lives by the way of NameSpace
The data classifications mark such as name prefix or name suffix, to simulate this independent " memory space ", to reach following realization
Effect (in the embodiment of the present invention for adding name prefix prefix): user is passed to mapping pair in operation data
That as (" data operation layer ") is data key name key, but key can be automatically converted to " prefix+key " simultaneously by data operation layer
LocalStorage is passed to as mapping major key to go to save.User is not aware that the data are real in localStorage in this way
It is stored separately according to NameSpace on border, user only needs that difference can be operated by generating different mapping objects
Data space, whether weight can occur with the key in another data space without the data be concerned about in a data space
It is multiple.
The present invention in specific implementation, has firstly, generating one by factory method (new Storage (" prefix "))
The mapping object of the NameSpace of standby uniqueness, the NameSpace can add name prefix prefix for data.Factory method
Mode (FACTORY METHOD) is a kind of common Object Creation type design pattern, and the core spirit of this mode is in encapsulation class
Constant part, extracting wherein personalized part apt to change is separate class, by relying on injection to reach decoupling, multiplexing and conveniently
The purpose that later maintenance is expanded.
The mapping object (" data operation layer ") of generation does number to the mapping object after being provided with name prefix prefix
When according to accessing operation, mapping object can add corresponding name prefix to the data key name key received.User can be for not
With the scope of business using different name prefix prefix (for example member data uses mem, gift data using gift etc.,
Independently defined by user, the present invention does not do any restrictions), and it is unique for keeping name prefix, so that it may reach isolation not
With the purpose of business datum.When user setup data, { key:value } key-value pair for transmitting data into mapping object, reflects
The key-value pair of one { prefix+key:value } can be generated by penetrating object i.e., so as to distinguish the data of different business.
In addition, for the data of client storage, many times all requirements of time-effectiveness.Data are not out of date
When, it can normally access, should be disposed once expired.The present invention uses " lazyness is removed " mode: when accessing data, doing
The expired inspection of data, normal return, otherwise clears data and returns to null value if data are not out of date.For can not be customized expired
The problem of time, the present invention are reflected by being packaged into one according to the key assignments value of data and the expired time time of user setting
The method of key-value pair elephant is penetrated to solve.Such as: it, can when user needs the expired time time of the data of the entitled key of set key
To be realized by calling setExpires (key, the time) method of mapping object (" data operation layer "), the Map Key of generation
Value is, for example: { val:value, expires:time }, then by the key name key of the data and the mapping key assignments of generation with key assignments
Pair form save.
The expired time of data is arranged by setExpires method, can be divided into two steps: acquisition key first is corresponding
Data；Then mapping key assignments is generated for the corresponding data of key, and is saved using key and mapping key assignments as a data object
Into localStorage.In this way, when needing to obtain the corresponding value of a key, if this key be not provided with it is expired
Time, then just directly returning to the corresponding storing data value of this key.If this key is provided with expired time,
Actually back in be a mapping key assignments, later, according to this mapping key assignments in include the corresponding mistake of " expires " parameter
Time phase time, and time is compared with local zone time to judge whether the data expired.If expired be returned to
Null value, and the corresponding value of the key in localStorage is deleted, and prompt this data of user out of date.If do not had
Phase is returned to the corresponding value of " val " parameter (that is: the corresponding value of key) in mapping key assignments included.
The realization process of technical solution of the present invention is specifically introduced below with reference to embodiment.
Fig. 1 is the schematic diagram of the main flow of the method according to an embodiment of the present invention that data manipulation is carried out in client.
The method for carrying out data manipulation in client of the embodiment of the present invention is by being arranged between terminal applies and local storage space
Data operation layer execute.Wherein, terminal applies are, for example, to be deployed in the various application programs of terminal, class of such as doing shopping application,
(merely illustrative) such as web browser applications, searching class application, instant messaging tools, mailbox client, social platform softwares；This
Ground memory space is, for example, to be located at local disk, CD, magneto-optic disk, semiconductor memory of client device etc., or be
USB (Universal Serial Bus, universal serial bus) flash disk for being connect with client device, mobile hard disk etc..
As shown in Figure 1, the method for carrying out data manipulation in client of the embodiment of the present invention mainly includes the following steps, namely S101 to step
Rapid S103.
Step S101: it obtains from the data operation request of terminal applies to operation data information, to operation data information
Including the key name to operation data；
Step S102: the key name to operation data is packaged into mapping major key；
Step S103: data manipulation is executed according to mapping major key.
In the present invention, data manipulation can be summarized as two classes: data save and data search, correspond respectively to mapping object
In two methods of setter and getter.According to the specific implementation process of data manipulation, data save operation may include number
According to newly-increased, data modification；Data look-up operations may include data query, data deletion.Below according in data operation request
Including the difference to operation data information, introduce the specific implementation procedure of data manipulation respectively.
Embodiment one: if further including the key assignments to operation data to operation data information, it may be assumed that operation data information be to
The key name and key assignments of operation data, the then process that step S103 executes data manipulation according to mapping major key are specific as follows:
Search whether local storage space preserves mapping key assignments according to mapping major key；
If not saving, using key assignments as mapping key assignments, then using map major key and map key assignments as encapsulate after to
Operation data；Otherwise, the corresponding mapping key assignments of mapping major key is obtained, and new Map Key is generated according to key assignments and mapping key assignments
Value, then will map major key and new mapping key assignments as after encapsulating to operation data；
Local storage space will be saved in operation data after encapsulation.
Specifically, may include: with the step of key assignments generates new mapping key assignments is mapped according to key assignments
Whether judge to map in key assignments comprising expired time；
If so, being judged according to expired time whether out of date to operation data, and deleted when operation data is out of date
Except to operation data, using key assignments as new mapping key assignments；When operation data is not out of date, obtain from mapping key assignments wait grasp
Make the expired time of data, and generates new mapping key assignments according to key assignments and expired time；
Otherwise, using key assignments as new mapping key assignments.
If may be newly-increased data, it is also possible to right to key name and key assignments that operation data information is to operation data
The data that local storage space saves are modified.When executing data manipulation, need according to the mapping major key generated by key name
Search whether that there are the corresponding data of mapping major key from local storage space.It if it does not exist, then is that data are newly-increased, and if it exists,
It is then data modification.Wherein, mapping major key can be by key name and the generation of data class indication.In this way, can be realized to difference
The data of business carry out classification isolation.
It is newly-increased for data, then can directly will to the key assignments of operation data as mapping key assignments, then will mapping major key with
The mapping key assignments is saved in local storage space in the form of key-value pair.
For data modification, firstly, obtain the corresponding mapping key assignments of mapping major key, and judge to map in key assignments whether include
Expired time.If comprising, judged according to expired time it is whether out of date to operation data, and when operation data is out of date
It deletes to operation data, at this point, executing the newly-increased process of data: using key assignments as new mapping key assignments, then will map major key
With new mapping key assignments as after encapsulating to operation data.When operation data is not out of date, from mapping key assignments in obtain to
The expired time of operation data, and new mapping key assignments is generated according to key assignments and expired time, then by mapping major key and newly
Map key assignments as encapsulate after to operation data；Otherwise, when mapping in key assignments not comprising expired time, using key assignments as new
Mapping key assignments, then will map major key and new mapping key assignments as after encapsulating to operation data.Finally, by after encapsulation
It is saved in local storage space in the form of key-value pair to the mapping major key in operation data with mapping key assignments.Wherein, it is protecting
Before data after depositing encapsulation, need to be deleted data previously stored in local storage space according to mapping major key, that is: really
Determining local storage space, there is no the corresponding data of mapping major key.
Embodiment two: if further including the key assignments and expired time to operation data to operation data information, it may be assumed that operand
It is believed that breath is key name, key assignments and expired time to operation data, then step S103 executes data manipulation according to mapping major key
Process is specific as follows:
According to key assignments and expired time generate mapping key assignments, then will map major key and map key assignments as after encapsulating to
Operation data；
Local storage space will be saved in operation data after encapsulation.
If being key name, key assignments and expired time to operation data to operation data information, may be newly-increased data and
Expired time is set, it is also possible to which key assignments and expired time to the data of local storage space preservation carry out whole modifications.This
When, either data are newly-increased or data modification can be directly according to key without searching corresponding data from local storage space
Name generates mapping major key, and generates mapping key assignments according to key assignments and expired time, then will mapping major key and mapping key assignments conduct
Key-value pair data is saved in local storage space.Wherein, before saving key-value pair data, it is thus necessary to determine that local storage space is not
There are the corresponding data of mapping major key, that is: if data modification, needing will be before local storage space according to mapping major key
The data of preservation are deleted.
Embodiment three: if further including the expired time to operation data to operation data information, it may be assumed that operation data information
For the key name and expired time to operation data, then step S103 executes the process of data manipulation specifically such as according to mapping major key
Under:
The mapping key assignments that local storage space saves is obtained according to mapping major key；
New mapping key assignments is generated according to expired time and mapping key assignments, then major key will be mapped and new mapping key assignments is made
For encapsulation after to operation data；
Local storage space will be saved in operation data after encapsulation.
Specifically, may include: with the step of key assignments generates new mapping key assignments is mapped according to expired time
Whether judge to map in key assignments comprising former expired time；
If so, judged according to former expired time it is whether out of date to operation data, and when operation data is out of date
It deletes to operation data, when operation data is not out of date, the key assignments to operation data is obtained from mapping key assignments, and according to key
Value and expired time generate new mapping key assignments；
Otherwise, the key assignments to operation data is obtained from mapping key assignments, and new reflect is generated according to key assignments and expired time
Penetrate key assignments.
If may be to be arranged for data are newly-increased to key name and expired time that operation data information is to operation data
Time phase, it is also possible to modify to the expired time for the data that local storage space saves.At this point, can be according to mapping major key
Search corresponding data in local storage space, and obtain mapping key assignments, then according to whether having expired in mapping key assignments when
Between determine newly-increased expired time or modification expired time.It is expired by included in mapping key assignments here for differentiation
Time is known as " former expired time ".
As shown in Fig. 2, being the operating process schematic diagram of the setting expired time of the embodiment of the present invention.When mapping key assignments in not
It is then newly-increased expired time when comprising former expired time.At this point, getting key assignments value from mapping key assignments, and according to key assignments
Value and expired time time generates new mapping key assignments { val:value, expires:time }, then reflecting the data
Penetrate major key and new mapping key assignments be saved in the form of key-value pair as encapsulated object local storage space (such as:
LocalStorage in).
It is then modification expired time when mapping in key assignments comprising former expired time.At this point, first according to former expired time
Judge it is whether out of date to operation data, and when operation data is out of date delete to operation data；When to operation data not
When expired, the key assignments value to operation data is obtained from mapping key assignments, and raw according to key assignments value and expired time time
The mapping key assignments { val:value, expires:time } of Cheng Xin, after then mapping major key and new mapping key assignments as encapsulation
Saved in the form of key-value pair to operation data.
Wherein, before saving key-value pair data, it is thus necessary to determine that there is no the mapping major key is corresponding for local storage space
Data, that is: if data modification, need to be deleted the previously stored data of local storage space according to mapping major key.
Example IV: if only including the key name to operation data to operation data information, step S103 is led according to mapping
The process that key executes data manipulation is specific as follows:
According to, to operation data, searching the corresponding data of mapping major key from local storage space after encapsulation.
If data manipulation at this time is that data query or data obtain to the key name that operation data information is to operation data
It takes.According to the method for data manipulation, data operation layer after receiving operation requests, will be generated according to key name mapping major key with
It realizes data encapsulation, corresponding data content is then searched from local storage space according to mapping major key.Also, it is deposited from local
After storing up the corresponding data of spatial lookup mapping major key, can also include:
Judge whether the data are expired；
If the data are not out of date or not set expired time, the data are returned；
Otherwise, the data are deleted, and return to null value.
Wherein, if not finding corresponding data according to mapping major key, null value is returned to, and prompt user.
In addition, after can finding data, continuing to execute delete operation when user needs to delete data.
According to the technique and scheme of the present invention, if expired time, mapping at this time can not be arranged by only needing to solve the problems, such as
Major key can be the key name key to operation data, no longer need to be generated according to key name key and data classification mark.If also needing
Solve the problems, such as that business datum can not be isolated, then mapping major key at this time is generated by key name key and data classification mark.

Make layer ") in, mapping object generates { prefix+key:value } key-value pair, then according to mapping major key prefix+key from originally
Search whether the data have expired time setting in ground storage localStorage.If not provided, directly saving { prefix+
Key:value } key-value pair is into localStorage；If there is and it is not out of date, then generate prefix+key:{ val:value,
Expires:time } } (time is the expired time of key, such as " 1515943718780 " to object, indicates the Chinese Industrial Standards (CIS) time
14 2018 23:28:38GMT+0800 of Sun Jan shows the key if the active client time is more than this time
Corresponding data are expired) and save to being locally stored in localStorage.If data are out of date, local deposit is deleted
The former data in localStorage are stored up, and { prefix+key:value } key-value pair that mapping object generates is saved in local
It stores in localStorage.
When user obtains data, data key name key value is transmitted into mapping object, and mapping object generates mapping major key:
Prefix+key, and corresponding data are inquired and obtained in local storage space localStorage as index, if data
Expired for empty or data, then data are unavailable, return to null value and prompt user；If data are not out of date or not set expired
Time, then returned data.
