Background technology
Present webpage is preserved form two kinds substantially.
A kind of is the form of HTML+ child resource, exactly current webpage is preserved into a html document, its picture, style sheet and script file etc. all preserve with an independent file separately, and the path of resource in html document all will be correspondingly revised as corresponding to the path that is saved in local file.
Another kind is the form of MHTML, exactly the web data packing of current page is saved in a file, and all data in webpage the inside are all saved in same file, without revising any page data.
The form of HTML+ child resource belongs to a kind of static preservation, can only preserve generated content of current page.If certain partial content is to generate by JS (JavaScript), when opening this html file of preservation, this part content can regenerate, and so just there will be the content of two parts of repetitions.This preservation form also has a lot of problems, and for example, some website, as Sina's microblogging, excellently cruel etc. done domain name restriction, can not preserve webpage by this form.In addition, also have restriction of base (basis) label etc., cause the webpage preserving to follow the discrepancy of original webpage very large.
MHTML form is followed MHTML standard, and the packing of all raw data of webpage is saved in the middle of a file, while opening file, can re-execute the operation that generates the page, so just there will not be the existing problem of form of above-mentioned HTML+ child resource.Because the page is to re-execute generation, thus if the in the situation that of suspension, and this webpage partial content is to depend on AJAX (asynchronous JavaScript and XML) request to generate, the page also cannot be reduced to the appearance of the original page so.And this problem can not exist for the form of HTML+ child resource.

Before embodiments of the invention are elaborated, first the AJAX technology relating in the present invention is carried out to brief description.
AJAX is the asynchronous JavaScript of Asynchronous JavaScript+XML(and XML) abbreviation.AJAX technology is the organic assembling of multiple development technique in fact, comprising: utilize XHTML and CSS technology to realize standard interface; Utilizing Document Object Model technology to realize dynamically shows and interactive function; Utilize XML and XSLT technology to realize exchange and the maintenance of data; Utilize XMLHttpRequest technology to realize asynchronous data retrieval; And utilize JavaScript that all are connected.
Traditional network program workflow is substantially as follows: the operation of client on webpage is converted into HTTP request and passes server back, and server accepts request and related data, resolution data send it to after corresponding processing unit, and the data converting to HTML page returning is returned to client.This workflow always allows user not feel well, because in the time of server process data, user can only wait for.Obvious user does not like every and does after single stepping, all needs waiting for server to return to new webpage, and what user wished is to use smoothly network program, the existence of even imperceptible server.
AJAX technology can be broken away from the network interaction mode of this stop-go, the method realizing is that AJAX inserts AJAX engine between client and server, AJAX engine writes with JavasSript, for be responsible for to draw the interface that client sees and communicate with server.After session starts, browser loads AJAX engine, rather than a webpage.AJAX engine can send to server by user's input by the mode of asynchronous communication, thereby avoids user seeing the response of blank webpage waiting for server.User's operation can be called the javascript function of an AJAX engine; former this conventionally can trigger a HTTP and ask to server; all responses to user's operation do not need to pass through server again; such as simple data check, Update Table searching web pages even, engine can process.If engine must server return data with response user's request, such as needing the data of server process submission or loading new code or data etc., engine can adopt the mode of asynchronous communication to send request, conventionally uses XML, thereby can not affect the mutual of user and program.
Each embodiment of the present invention is described below with reference to accompanying drawings.

Webpage store method and webpage save set
The webpage specifically describing in Fig. 1 to Fig. 4 below with reference to Fig. 3 is preserved step.Fig. 3 shows the indicative flowchart of webpage store method according to an embodiment of the invention; Fig. 4 shows the indicative flowchart of webpage store method according to another embodiment of the present invention.
As shown in Figure 3, in step S110, when holding instruction receiving webpage from network Web page loading, with MHTML form, the page data of this webpage is kept in local storage unit 30.
Then,, in step S120, whether the webpage that judgement is preserved comprises AJAX request.While not comprising AJAX request in preserved webpage, flow process finishes.Described AJAX request is a request in browser application, and its core is xmlhttprequest, and this request need not refresh the page.
While comprising AJAX request in preserved webpage, at step S130, AJAX resource and the AJAX request of based on described AJAX request, obtaining are kept to this locality explicitly, such as being kept in local storage unit.Described AJAX resource can be when from network Web page loading, and by network, from storing, the web page server of AJAX resource downloads.Or described AJAX resource also can be obtained from web page server by other approach.
Here, AJAX resource can be the data relevant with the broadcasting of content-data.For example, in the situation that content-data is video content, AJAX resource can be video (video) label of video content.Video tab can relate to some attributes of video etc.When displaying video content, need to obtain video tab.
Here, described AJAX request can comprise the URL address of AJAX resource, the network address of described URL address indication for obtaining AJAX resource.Described AJAX resource and described AJAX request can be kept in the local data base of storage unit 30 with the form of database.For an AJAX resource, database has two field key and value, and field key is the URL address of AJAX resource, and field value is corresponding data, i.e. AJAX resource.Like this, in the URL address comprising, just can in local data base, search corresponding AJAX resource in parsing AJAX request.
In addition, above-mentioned webpage store method can be enabled multi-process and realize, and such as utilizing a process to preserve page data, and enables the preservation that another process is carried out AJAX resource.In this case, step S110 can with step S120, S130 executed in parallel, also can carry out successively in any order.
Fig. 4 shows the indicative flowchart of webpage store method according to another embodiment of the present invention.Embodiment shown in Fig. 4 is the improvement to the embodiment shown in Fig. 3.Compare with Fig. 3, the difference of the embodiment shown in Fig. 4 is only to utilize step S131, S133 and S135 to replace the step S130 in Fig. 3, and other step is identical.For illustrative ease, at this, only difference is described.
As shown in Figure 4, while comprising AJAX request in judging preserved webpage, at step S131, in internal memory, create for preserving the AJAX caching resource of the AJAX resource of obtaining based on described AJAX request.Then,, at step S133, described AJAX resource and described AJAX request are kept in described AJAX caching resource explicitly.Then, at step S135, by the described AJAX resource of preserving in described AJAX caching resource, with the form of database and described AJAX request, be saved in local data base explicitly.
According to this embodiment, opening the method for the local webpage of preserving in the situation that the new webpage loading comprises AJAX request, in the AJAX buffer memory by the AJAX caching resource obtaining based on AJAX request in internal memory.In one example, can all be buffered in AJAX buffer memory for the AJAX resource based on AJAX acquisition request in all pages.In another example, also can be only in the situation that user has sent webpage and has held instruction, just enable AJAX buffer memory, by these AJAX caching resources in AJAX buffer memory.Like this, can reduce the consumption to internal memory.It can be by directly selecting the instruction of preserving webpage to initiate by user that webpage is held instruction, and also can be in response to other instruction and activate.
Here, take the situation of WebKit is further illustrated as example.The buffer structure of WebKit is such: MemoryCache->AppCache->HTTPC ache.Can between AppCache and HTTPCache, create AJAX buffer memory AJAXCache, for buffer memory AJAX resource.Because being buffered in network layer, realizes this AJAX, so without the code of revising WebKit.
In addition,, in order to save memory headroom, in the embodiment shown in Fig. 3 and Fig. 4, can also comprise AJAX caching resource situation step.Such as, can be after browsing close, empty and allly in AJAX caching resource browse to this AJAX resource that window is relevant.Or, can, by after AJAX resource conservation is in local data base or when advancing in response to webpage or webpage retreats instruction and again networks Web page loading, empty all AJAX resources corresponding to webpage of institute's buffer memory in AJAX buffer memory.
In addition, in step S133, preserve the step of AJAX resource and can in network adaptation layer, carry out, can avoid like this WebKit to modify.What certainly, in said method, comprise also can carry out respectively in other layer.
Fig. 5 shows the schematic block diagram of webpage save set 10 according to an embodiment of the invention.
As shown in Figure 5, webpage save set 10 comprises page data storage unit 110 and AJAX resource conservation unit 120.
Page data storage unit 110, for after receiving webpage and holding instruction, is preserved the page data of described webpage with MHTML form.The in the situation that asking for comprise AJAX at described webpage AJAX resource conservation unit 120, AJAX resource and the AJAX request of based on described AJAX request, obtaining are kept in local data base explicitly.
In another example of the present invention, webpage save set 10 can also comprise the first judging unit (not shown), for judging whether described webpage comprises AJAX request.
Corresponding with the webpage store method shown in Fig. 4, in another embodiment of the present invention, webpage save set 10 can also comprise AJAX caching resource creating unit 130 and AJAX caching resource storage unit 140.
AJAX caching resource creating unit 130, for comprise AJAX request in the situation that at described webpage, creates for preserving the AJAX caching resource of the AJAX resource of obtaining based on described AJAX request in internal memory.AJAX caching resource storage unit 140 is for being kept at explicitly described AJAX caching resource by described AJAX resource and described AJAX request.Then, AJAX resource conservation unit is the described AJAX resource of preserving in described AJAX caching resource, with form and the described AJAX request of database, is saved in local data base explicitly.
Similarly, in order to save memory headroom, can also provide in addition AJAX caching resource to empty unit (not shown).Such as, AJAX caching resource empties unit and can be configured to after browsing close, empties allly in AJAX caching resource to browse to this AJAX resource that window is relevant.Or, AJAX caching resource empties unit and can be configured to, by after AJAX resource conservation is in local data base or when advancing in response to webpage or webpage retreats instruction and again networks Web page loading, empty all AJAX resources corresponding to webpage of institute's buffer memory in AJAX buffer memory.
In an example of the present invention, can be only in the situation that user has sent webpage and has held instruction, just enable AJAX buffer memory, by these AJAX caching resources in AJAX buffer memory.Like this, can reduce the consumption to internal memory.It can be by directly selecting the instruction of preserving webpage to initiate by user that webpage is held instruction, and also can be in response to other instruction and activate.In this case, webpage save set 10 can also comprise that webpage is held instruction and activates unit (not shown).Webpage is held instruction and is activated unit and be configured to, in response to the instruction of preserving the content-data in page data, activate the instruction of preserving webpage.
Webpage deployment method and webpage device for opening
Below with reference to Fig. 7 to Figure 11, webpage deployment method and webpage device for opening are according to an embodiment of the invention described.
Fig. 7 is the schematic flow diagram of webpage deployment method according to an embodiment of the invention.
As shown in Figure 7, at step S210, after receiving the web page browsing instruction of the webpage of browsing webpage store method preservation as shown in Figure 3, the page data based on preserving with described MHTML form carries out webpage loading.Then,, at step S220, whether judgement, when loading described webpage, produces AJAX request.If do not produce AJAX request, flow process finishes.
When producing AJAX request when loading described webpage, at step S230, from this locality, read with described AJAX and ask corresponding AJAX resource.Here, in one example, from this locality, read with described AJAX and ask corresponding AJAX resource to comprise: based on described AJAX request, from local data base, read with described AJAX and ask corresponding AJAX resource.Or, in another example, in the situation that this locality exists described AJAX caching resource, described reading from this locality with described AJAX asks corresponding AJAX resource to comprise: based on described AJAX request, read with described AJAX and ask corresponding AJAX resource from described AJAX caching resource.Here, from this locality, read the operation of AJAX resource and can network adaptation layer, carry out, can avoid thus WebKit code to modify.
Then, at step S240, the page data based on loaded and the AJAX resource reading, the generating web page page.
In addition, described AJAX request can comprise the URL address of AJAX resource, and described AJAX resource and described URL address are kept in described local data base explicitly.The URL that Fig. 8 schematically shows based in AJAX request reads the process flow diagram of the method example of AJAX resource from local data base.
As shown in Figure 8, while producing AJAX request when judging Web page loading, first, at step S2310, obtain the url list of all URL address of the AJAX resource of preserving in local data base or AJAX caching resource.Then,, at step S2320 and S2330, according to the URL address in described AJAX request, described url list is carried out to complete matched and searched.
While finding the URL address (result of step S2340 is yes) of mating completely in described url list, at step S2340, from described local data base or AJAX caching resource, read the AJAX resource corresponding with found URL, and obtained AJAX resource is returned to browser kernel (such as Webkit kernel) play up (step S2350).
While not finding completely the URL address (result of step S2340 is no) of coupling in described url list, use the regular expression of the URL in described AJAX request to carry out fuzzy matching and search, and in step S2370, judge whether to exist matching result.
If there is no matching result (result of step S2370 is no), returns to sky data.If there is matching result (result of step S2370 is yes), at step S2380, judge that whether existing matching result is more than one.
If find a unique matching result (result of step S2380 is no), turn back to step S2340, from described local data base or AJAX caching resource, read the AJAX resource corresponding with found URL address.If the matching result finding, more than one (result of step S2380 is yes), returns to sky data.
In addition, because AJAX resource itself is the resource of dynamic requests, in most cases, the URL address of request is also dynamic change, so while initiating inquiry, can first carry out domain name judgement, then mate completely, coupling is carried out regular expression fuzzy matching again with raising efficiency and hit rate in not.
By using the AJAX resource from local data base, can carry out the inter-related task that sends corresponding AJAX request in the page.In the situation of the displaying video of mentioning in the above, AJAX resource is video tab.There is video tab, just can play and store local video frequency program into.
Thus, even the in the situation that of suspension, also can respond the AJAX request in webpage by the AJAX resource being kept in local data base, thereby carry out the inter-related task on webpage.In the example of off-line video, in response to AJAX request, from local data base, obtain video tab, thereby the in the situation that of networking not, also normal off-line displaying video.
Being kept at local webpage can open in the situation that not networking, and also can under networking state, open.Under networking state, preferably can obtain AJAX resource from network.Like this, when the AJAX resource on network changes, can use in time the AJAX resource after renewal.
Fig. 9 has provided the process flow diagram of the modification of the webpage deployment method shown in Fig. 7.Compare with Fig. 7, the difference of the embodiment shown in Fig. 9 is only to have increased step S940 and step S950, and other step is identical with Fig. 7.At this, only increased step S940 and step S950 are described.
As shown in Figure 9, judge and when Web page loading, produce after AJAX request in step S220, at step S940, whether the terminal device of web page browsing is carried out in judgement current in networking state.If in networking state, at step S950, by Network Capture AJAX resource.Subsequently, flow process proceeds to step S240.
If in suspension state, proceed to step S230, from this locality, read with AJAX and ask corresponding AJAX resource.Subsequently, flow process proceeds to step S240.
Figure 10 is the schematic block diagram of an embodiment of the webpage device for opening 20 in Fig. 2.As shown in Figure 2, webpage device for opening 20 comprises page data loading unit 210, AJAX resource reading unit 220 and webpage generation unit 230.
Page data loading unit 210 is for after receiving the web page browsing instruction of the webpage of browsing webpage store method preservation as shown in Figure 3, and the page data based on preserving with described MHTML form carries out webpage loading.AJAX resource reading unit 220, for when producing AJAX request when loading described webpage, reads from this locality with described AJAX and asks corresponding AJAX resource.Webpage generation unit 230 is for the page data based on loaded and the AJAX resource that reads, the generating web page page.
In an example of the present invention, described AJAX resource reading unit can be configured to, based on described AJAX request, read with described AJAX and ask corresponding AJAX resource to generate described webpage from local data base.
