Particularly, in the present embodiment, subscriber equipment has loaded the webpage that comprises Internet resources.It should be noted that, webpage can only present the Internet resources that it comprises now being, and for example, the Internet resources that webpage comprises are Word or PDF document, can directly present this Word or PDF document.
As a kind of example, following embodiment mainly describes with the webpage based on HTML (HTML), title (title) label/element, head (head) label/element, painting canvas (canvas), link (link) label/element, hypertext related in giving an example as following are quoted (href) attribute etc., all can carry out clear and definite its implication by inquiry HTML specification; But, those skilled in the art are to be understood that, webpage of the present invention is not limited to html web page, and can correspondingly expand to other webpages, as expanded hypertext markup language (XHTML) webpage, extend markup language (XML) webpage etc.
In step S1, when the Internet resources in webpage are triggered while downloading, set up in this locality link application that should Internet resources.
Wherein, the download that can be triggered in multiple situation of the Internet resources in webpage.For example, subscriber equipment is iPad, and closed system is IOS system, and the Internet resources in webpage are document; User carries out the operation of " being added into main screen " to the webpage that is directly rendered as document, the download that is triggered of the document in webpage.It should be noted that, should be for example only for technical scheme of the present invention be described better, but not limitation of the present invention, those skilled in the art should understand that, Internet resources in any webpage be triggered download implementation, for example, the mode of webpage shortcut link or Internet resources shortcut link etc. is set up in other triggerings, all should be within the scope of the present invention.
Wherein, the link information that comprises the webpage that comprises Internet resources is applied in described link, and can be used in and link to the webpage that comprises these Internet resources.For example, in upper example, when user carries out after the operation of " being added into main screen " being directly rendered as the webpage of document, the link information that comprises this webpage is applied in the link of setting up, and this link application start, for example user clicks this link application, and it can be for triggering browser, as the apple browser (Safari) in IOS system etc., the webpage that access comprises these Internet resources.
Particularly, when the Internet resources in webpage are triggered while downloading, set up in this locality to the mode of link application that should Internet resources include but not limited to following any one:
1) set up icon and be rendered as the link application of text message.
For example, Internet resources are document, by searching the title label of head part, determine that document title is " XXX ", and device, by canvas, generates base64 data, and these base64 data, in the time being moved to represent to user, are rendered as text " XXX "; And, device generates link label, and be generated base64 data by the href setup of attribute of this label, thereby the icon information using these base64 data as link application, and, device is the attribute that closed system can be identified as application by the rel setup of attribute of link label, as is set to IOS system and can be identified as " apple-touch-icon " attribute etc. of desktop application.
2) obtain the icon information of link application, and set up described link application in this locality, this link application is rendered as described icon information while not being activated.
Wherein, the mode of obtaining the icon information of link application include but not limited to following any one:
A), according to the link label in the head part of webpage, obtain the icon information of link application.
B), according to the image links address information comprising in the configuration file of webpage, download original image information; And according to the resource identification relevant information of Internet resources, process described original image information, obtain the icon information of described link application.Wherein, described resource identification relevant information comprises any information that can be used in these Internet resources of identification; For example, Internet resources title, type etc.Preferably, this resource identification relevant information can be contained in webpage; For example, Internet resources title can be contained in the title part in webpage etc., and this title part can be determined by title label.
For example, the image links address information of the original image information comprising in access-profile, and download original image information based on this image links address information; Then, pass through canvas, on this original image information, add Internet resources title, and the small icon of drawing expression network resource type, then, call the application programming interface (API) that canvas provides, image after treatment is converted to base64 coding, as the icon information of link application.
Because the image that the link label based in head element obtains cannot be changed, therefore, if the link label of employing based in head element obtains the mode of icon information, and need to set up individual icon for different Internet resources, need in advance for different Internet resources generate individual icon, and obtaining by the link label in head element the individual icon that this generates in advance, this is comparatively loaded down with trivial details undoubtedly; And in this implementation, for different Internet resources, also only need obtain identical original image information and it is processed, can generate the individual icon for heterogeneous networks resource, thus, the image of having avoided the link label based in head element to obtain cannot be changed and need to be the problem that different Internet resources set in advance different individual icons.
Wherein, be set to the icon information of its acquisition by the icon of link application, set up the described link application that is rendered as described icon information while not being activated in this locality.Preferably, the operation of the interpolation application that can carry out according to user, as the operation of performed " being added into main screen ", will set up the described link application that is rendered as described icon information in this locality.
For example, closed system is IOS system, device generates link label, and be generated icon information by its href setup of attribute, and be " apple-touch-icon " by its rel setup of attribute, thereby carry out user after the operation of " being added into main screen ", generate the link application that is rendered as on the table obtained icon information while startup.
It should be noted that, above-mentioned for example only for technical scheme of the present invention is described better, but not limitation of the present invention, those skilled in the art should understand that, any icon information that obtains link application, and set up the implementation that is rendered as the described link application of described icon information while not being activated in this locality, all should be within the scope of the present invention.
Then,, in step S2, Internet resources are downloaded in the buffer memory of distributing to link application.
In the present embodiment, do not limit Internet resources being downloaded to the opportunity of distributing in the buffer memory that links application, for instance, can be after link application be set up, immediately Internet resources are downloaded in the buffer memory of distributing to link application, also can, in the time that link application is started first, Internet resources be downloaded in the buffer memory of distributing to link application.
For example, after link application is set up, resource downloading address informations that comprise in access-profile, Internet resources, are downloaded to Internet resources in Web page structural query language (WEB SQL) database of distributing to link application.
Wherein, in the time that Internet resources are document, can, using " document id " and " document number of pages " as associating major key, document be inserted in cache database.And before this link application start, download section is divided the document of number of pages, can continue to download the document of all the other numbers of pages after local links application start, thereby realize breakpoint transmission.
Preferably, when can be used in the buffer memory of distributing to link application, the part of storage networking resource is full, and for example the data in WEB SQL database completely time, can first empty this partial buffering or delete the partial content in this partial buffering, then down loading network resource.
It should be noted that, in the process of carrying out in step of the present invention, the device of carrying out said method can add this locality, distributes in the buffer memory of link application, so that device also can executable operations after webpage is closed as added.And those skilled in the art will be understood that as adapting to different memory locations and for realizing corresponding function, adding the device in buffer memory that corresponding change can occur.
