Below technical solution of the present invention is introduced more in detail.
The present invention can realize the superseded unnecessary resource data of browser background intelligent according to the access time, discharges the space shared by these data.Such as can set a time interval value, such as 3 days.Once after the resource data of offline storage arrives capacity limit, eliminate the data that the user more than 3 days does not access, discharge space.But superseded resource mode so merely may can not meet the demand of certain customers, such as certain user often accesses the website of a large amount of use offline cache, the particularly website of aspects of game play, that is user uses offline storage function ratio more frequent, like this, the capability value of acquiescence may can not meet far away.Therefore, the present invention improves further, carries out capacity distribute adjustment according to service condition.When arriving capacity threshold, if the spacing value (difference namely) of the last access time distance current time of the data that user does not access at most is less than the spacing value of setting, just illustrate that this user uses offline storage function ratio more frequent, demand is larger, therefore be not suitable under these circumstances directly eliminating data, but give the capacity of user's overabsorption one times, the use habit of the user that like this just more fits.
Fig. 2 is the processing flow chart of the embodiment of the present invention 2 offline storage data.
In this embodiment 2, preset the offline storage capacity limit of an acquiescence, the memory capacity limit default setting of a such as former correspondence is 10M.Set a time interval value in addition, such as 3 days.Once after the resource data of offline storage arrives capacity limit in this embodiment, just according to " data used recently by the likelihood ratio of reusing comparatively early use large many " rule, the data that user does not access at most are eliminated, discharge space.It should be noted that, the storage of offline storage resource data of the present invention divides with Manifest file, that is this Manifest file has not for a long time had accessed, just this Manifest file and the resource data corresponding to it can be eliminated together.Manifest file, namely inventory file, listing which resource data in this document needs to carry out offline storage, and which resource data needs to be in networking state and some reserved resources always.Resource data generally refers to primary resource in this file and all child resources.Resource data is generally appear in Manifest file with the form of URL.Primary resource is exactly this file itself, and child resource is exactly resource referred in this document, such as JS file, CSS file, picture and multimedia file etc.
As shown in Figure 2, step is comprised:
S201, reception HTML5 resource data carry out offline storage.
S202, judge whether the resource data of offline storage arrives the offline storage spatial content threshold value of setting, if so, enters step S203, if not, enter step S206 and proceed to store.
S203, judge that whether the mistiming of last access time and the current time of the resource data of offline storage is larger than the time interval value pre-set, if so, enter step S204, if not, enter step S205.
The method that this step judges is, checks the last access time of the resource data (being also Manifest file) stored in a database.The last access time of reading all resource datas from database sorts, and being worth minimum just representative has not for a long time had accessed.That is the time that the time gap of the last access of this resource data is current is the longest.The principle of ordering of access time is the current time is larger than the value of the time in past, no matter carry out numerical value relatively or the comparison of character string.
Then, judge that whether the last access time of resource data is larger than the time interval value pre-set with the mistiming of current time.Such as, current time is 2012-05-15, and the last access time of a resource data is 2012-05-13, the access time of another resource data is 2012-05-11, then the latter be exactly do not have at most accessed, that is this file does not have the accessed time the longest, because the former does not have the accessed time to be 2 days (be namely 2 day with the mistiming of current time), the latter does not have the accessed time to be then 4 days (be namely 4 day with the mistiming of current time), is greater than the time interval value that pre-sets 3 days.
It should be noted that, because this superseded method be according to the access time carry out for a long time resource data eliminate, therefore resource data is needed to sort by the access time, conveniently find out and do not have accessed resource data at most to eliminate, such sequence also can more easily be found out, and sorts by other means and be also fine.
S204, eliminate the resource data larger than the time interval value pre-set with the mistiming of current time of last access time, enter step S206.
S205, expanding memory capacity by adjusting described offline storage spatial content threshold value, entering step S206.
Judge in step S203 that the last access time of the resource data of offline storage is less than the time interval value pre-set with the mistiming of current time, then this step S205 adjusts described offline storage spatial content threshold value to expand memory capacity.
Such as, the value that before sets interval is 3 days, current time is 2012-05-15, and minimum access time value is 2012-05-14, the representative of this value does not have accessed at most, and this mistiming is 1 day, less than the time interval value 3 days of default setting, then illustrate that this user uses offline storage Property comparison frequent, and demand is larger.That is, user is using offline storage every day, and offline storage space reaches the upper limit, therefore, illustrate that this user have accessed the website of a lot of offline storage or the system of Web App(sing on web and application), the demand of this user to offline storage is larger.Accordingly, be just 20M for this user adjusts offline storage spatial content threshold value, namely expand and be twice memory capacity, memory capacity expands as 20M.So analogize, if expansion can't meet after being twice, just carry out again once according to above-mentioned steps.
S206, offline storage is carried out to resource data.
This step continues to carry out offline storage to resource data.If but while offline storage resource data, capacity reaches the full quota again again, then stop carrying out offline storage, and repeat step S203, then eliminate a resource data, and then the offline storage of this resource data again.
It should be noted that, the present invention can also arrange data further and eliminate the time, and such as default setting is 15 days.After each startup browser or regularly on backstage to judge that whether the absolute value of difference of last access time distance current time of all resource datas eliminates the time than data large, if large words are just eliminated automatically, otherwise do not process.
Also it should be noted that, if current capacities had carried out dilatation automatically, and after eliminating data, residual capacity is also greater than default capability threshold value, then carry out subtracting appearance (from another one angle, also be that used capacity is less than or equals the difference of current capacities threshold value and default capability threshold value, then carry out subtracting appearance).Such as, default capability threshold value is 10M, and it is 30M that current capacities threshold value carried out dilatation, and after having eliminated data, presently used capacity is 19M, then there is the redundant space of 11M, i.e. residual capacity 11M, also larger than the default capability threshold value 10M of former setting, so just carry out the operation subtracting appearance, capacity threshold is reduced to 20M, and residual capacity is 1M, saves the 10M capacity of distribution.If residual capacity is less than or equal to default capability threshold value, as being less than or equal to 10M, then constant.If residual capacity is also larger than certain multiple of default capability threshold value, then reduce current capacities threshold value to being less than default capability threshold value, such as, residual capacity 22M, also larger than the twice of default capability threshold value 10M, then reduce current capacities threshold value to residual capacity is 2M.The object of such process be user in order to carry out expanding capacity threshold when certain section for a long time in do not visit again website or the WebApp of offline storage, can effective Free up Memory.Which can setting options in a browser, allow user can select the superseded time of data, and the frequency of background process.The frequency of background process here refers to when browser can eliminate data automatically, such as, when starting browser or only clear up every day once etc. at every turn.
Also it should be noted that, above all operations all completes on backstage, there will not be the situation affecting user and use.Also the example that just employing one was concrete in above-mentioned said default value 10M and 3 day is illustrated, and this value can be arranged according to the feedback data of user, makes more to meet user's request.
The present invention goes for mobile phone browser and PC browser.The browser of the following stated can be PC browser, also can be mobile phone browser.On a web browser, the data of offline storage are kept at this locality, if user does not manually delete, only can get more and more, and it can't eliminate by browser automatically, like this, some website is only accessed once, all no longer have accessed later, but the data of its offline storage can exist always, if user does not delete, these data will permanently exist, occupy memory headroom, affect internal memory and use.By the inventive method, whether user without the need to worrying that whether storage space is full, can exist the junk data of some offline storage, and the help user that browser can be intelligent eliminates least-recently-used data, thus release storage space.
Again such as, on a web browser, if once offline storage capacity limit set by arriving time, visit again one new when needing the Web App of offline storage, the offline storage request of this Web App will be cancelled, do not continue this Web App resource data to be saved in this locality.Because container is full, can not refill thing, namely mean, user does not manually delete some offline storage resource datas taken up space, and the offline storage function of these other Web App will always " inefficacy ".Pass through the inventive method, if time capacity arrives the threshold value of initial setting up, browser will carry out eliminating of resource data automatically, for new access discharges space, occurs the situation of the offline storage function " inefficacy " of other Web App after capacity would not have been made like this to expire.But user uses offline storage function ratio more frequently in situation, can the subject of knowledge and the object of knowledge least-recently-used data of eliminating, user sometimes also can have access to.Under these circumstances, superseded data blindly, may will affect the experience of user, therefore the present invention further provides the processing mode dynamically arranging memory capacity threshold value.When user uses this offline storage function ratio more frequently time, for this user distributes more storage space, to meet consumers' demand.
