Description
Technical Field
The embodiment of the invention relates to the technical field of network televisions, in particular to a method and a device for accessing page resources, electronic equipment and a storage medium.
Background
The interactive network television (Internet Protocol Television, IPTV) is a technology for providing various interactive services such as data television to home users by integrating various technologies such as the internet, multimedia, communication and the like by utilizing a broadband cable television network. Because the existing IPTV is based on single-page resource access, when a user of the IPTV service operates a page resource, return operation is often used, the user hopes to return to an original page from a current azimuth page, and the common page return skip technology at present is as follows:
1. the method and the device have the advantages that the JavaScript original application interface is used for realizing page return, for example, history. Go (-1) is used for page return, and the method and the device are of a traditional browser-server architecture, have the advantages of small code quantity and simple logic, and can be realized only by using the basic application interface of a browser container. The defects are that: (1) The state before the page jump cannot be restored, and the focus cannot be memorized. (2) Returning to logic solidification, when intermediate pages such as a transfer page and a loading page exist, the problem that normal rollback cannot be performed exists. (3) When a user accesses the cross-platform service resource, the user state is easy to be abnormal when the user returns to the service page of the platform.
2. Page return is achieved using a client store return stack chain, which is the currently prevailing dynamic page access technique. The advantages are that: compared with the original application interface page return, the method has the advantages that the method is more accurate and more controllable, effective storage can be selected, page data and states before user page jump can be accumulated, and the original page state can be restored when the original page is returned. The defects are that: (1) The client has limited storage space and cannot buffer a large amount of data. (2) The client is unstable and the problem of storage loss easily occurs. (3) When the returned target page is taken off shelf or deleted, error reporting is easy to occur. (4) increasing the computational pressure of the client.
3. The page return is realized by using a server-side storage user return stack chain: and storing a user linked list by using a HashMap structure at a server, wherein the user linked list takes a user unique identifier ID as a Key Value and a page azimuth stack chain as a Value. The advantages are that: compared with a return stack chain stored by the client, the storage of the server is more stable and controllable. The defects are that: (1) Because the access paths of different users are basically consistent, the return stack links stored by the server are basically the same, and a great amount of redundancy exists in the storage of the server. (2) Since both calculation and storage are implemented at the server side, the pressure of the server increases.
4. Page return is achieved using a fixed page access path: the page access is fixed, and both the page jump and page return are fixed. The method has the advantages that: the code logic is simple and stable. The defects are that: dynamic page access cannot be realized, service expansibility is limited, and most of dynamic service requirements cannot be met.
In summary, a method for accessing page resources to realize page return on the premise of low storage and low overhead is urgently needed at present.

Example III
Fig. 6 is a flowchart of a method for accessing a page resource according to a third embodiment of the present invention, where the embodiment of the present invention may be applicable to a case where page return is implemented in a page access process of an IPTV, where the method may be implemented by a page resource accessing device, where the device may be implemented by using hardware and/or software, and is generally integrated in a client, and referring to fig. 6, the method provided by the embodiment of the present invention specifically includes the following steps:
The user control instruction may be information for controlling the client to display a page, for example, the user control instruction may be information input by the user on the client interface by clicking, touching or sliding the page, and the user control instruction may also be control information generated by the user through a remote controller of the client. The current page information may be information of a page being displayed in the client, may be information such as a network address or URL of the current page information, the sub page information may be an interface for controlling a next display of the client by a user, and an interface corresponding to the sub page information may have an association relationship with a page corresponding to the current page information, for example, a skip link or a skip control of the next display interface may be a part of the interface currently displayed by the client. The page resource access information can be information for controlling information resources displayed on the display interface, can be information such as a network address or a URL, and can enable the client to access information resources such as characters, sounds and animations.
In the embodiment of the invention, the client may receive a user control instruction, where the user control instruction may be information input by a user and used for controlling interface access, for example, the client may receive control information sent by the user through a remote controller, where the control information may control IPTV to perform a channel change operation. When the client receives a user control instruction, the current page information of the page which the client is accessing and the sub-page information of the page which needs to be accessed can be sent to the server, the server feeds back the page resource access information according to the received current page information and the sub-page information, and the client can display the page according to the page resource access information.
It may be understood that the page resource access information fed back by the server may be an information resource corresponding to the sub-page information, for example, when the sub-page information is an identification number of the sub-page or location information of a jump link of the sub-page, the server may search for a URL of the sub-page according to the identification number or location information of the jump link and feed back the URL to the client, and the server may access the resource of the sub-page according to the URL and display the sub-page.
The page return operation may be an operation of controlling the page to return to a previous access page or to previous access pages, for example, the page return operation may be control information generated by the user pressing a return button in a remote controller of the client. The page to be accessed may be a page accessed by the client between the current access interfaces.
Specifically, when receiving a page return operation of a user, the client may send the page return operation to the server, trigger the server to search page resource access information of a corresponding page to be accessed, and send the page resource access information to the client, so that the client realizes the return of the access page according to the fed back page resource access information. For example, the user clicks or touches a return button in the client, the client generates control information corresponding to the page return operation, and the control information can be sent to the server to obtain page resource access information of a previous page stored in the server, so that the client revisits the previous page.
According to the embodiment of the invention, the display interface is accessed through the control access instruction of the user, the current page information to be accessed and the sub-page information to be accessed are sent to the server side, the page return operation of the user is received, the page return operation is sent to the server side, the page resource access information of the page to be accessed is sent to the client side by the server side, the page return operation of the client side is realized, and the display quality of the page is improved.
Further, on the basis of the above embodiment of the present invention, the sending, to a server, current page information to be accessed and sub page information to be accessed to obtain page resource access information for display includes:
carrying the current page information and sub page information to be accessed in a uniform resource locator and sending the uniform resource locator to the server side; and acquiring page resource access information fed back by the server side, and displaying page resources corresponding to the page resource access information.
In the embodiment of the invention, the client can send the current page information and the sub-page information to the server through the uniform resource locator, for example, the client can send the current page information and the sub-page information through the URL, wherein the current page information can be specifically a webpage identification number of a currently accessed webpage, the sub-page information can be a jump link or a position coordinate of a jump control in the currently accessed webpage, and the webpage identification number and the position coordinate can be sent to the server at the tail of the URL.
Specifically, after sending the URL, the client may monitor the server to obtain the page resource access information fed back by the server, and the client may obtain the information resource according to the page resource access information, and may implement the page through the display of the information resource.
Further, on the basis of the above embodiment of the present invention, the sending the page return operation to the server to obtain page resource access information corresponding to a page to be accessed to implement page return includes:
packaging the current page information to the page return operation, and sending the page return operation to the server side; and receiving page resource access information fed back by the server side, and displaying page resources corresponding to the page resource access information.
In the embodiment of the invention, the page return operation can trigger the operation information of the server, so that the server side can search the page resource access information of the page to be accessed, and when the client side sends the page return request to the server side, the current page information can be packaged in the page return operation, so that the server side can acquire the accurate page to be returned. The server side can feed back page resource access information of the page to be returned to the client side, so that the client side can access the page resource according to the page resource access information to realize page return.
For example, the page returning operation may specifically be a URL request, and the page identifier of the page to be returned may be added at the tail of the URL request, so that the server may obtain the page resource access information of the page to be returned in the public resource cache book in the foregoing embodiment, and the server side feeds back the page resource access information to the client side, where the client side obtains the page resource of the page to be returned according to the page resource access information, so as to implement page returning.
In one exemplary embodiment, tree structure data is dynamically generated at the server side according to a user's resource request. The tree structure reflects the user's resource access order. When the user uses the return operation, the target resource is acquired from the tree structure data. When the corresponding resource is put off the shelf and deleted, the corresponding operation can be performed in the tree structure data in time, and the user is prevented from accessing the wrong resource after returning to the operation. Compared with the method using the client to store the return stack link, the method is more stable and safer. And meanwhile, compared with a mode of using a server side to store a user return stack link, the method reduces more data redundancy and the stress of the server. The data in the tree structure is dynamically changed according to the user request resource, and has good scalability and expansion capability. The method for realizing page return by using the tree structure can comprise the following steps:
1. the tree structure takes an entry page as a root node, the entry page has a unique identification ID, each non-root node of the tree structure points to a father node, and each entry page of each external entry in IPTV service can have a corresponding tree structure.
2. When a user accesses service resources from an external portal, a corresponding HashCode can be obtained as a root node identifier according to an entry page URL of the corresponding external portal, whether a corresponding tree structure exists or not is searched in a memory according to the root node identifier, if the corresponding tree structure does not exist, a root node is created by taking the HashCode as the identifier, and the root node identifier is returned; if the corresponding tree structure exists, the unique identification of the root node of the tree structure is directly returned.
3. The page code can generate a global unique identifier of the page in a hash mode according to a page template file containing a full path, the relative position (such as the leaf node of the third time) of the page in a tree structure and a root node identifier, node data of the page in the tree structure comprises the global unique identifier of the page, a page URL, a node position, a node name, a father node pointing, a child node pointing set and the like, wherein the child node pointing set is a Map set taking the jump link of the child node on the corresponding page of the node or the position of a jump control as a key, and the pointing address is taken as a value.
4. When the user generates a page resource request in the service, the global unique identification of the current page and the resource request position are transmitted to the server side. The server side obtains the page node according to the global unique identification of the current page, and searches whether the node is in the target child node in the child nodes of the node data. If the child node does not exist, the child node is added to the corresponding child node set before the target page resource is rendered by generating the corresponding child node with the target resource URL, and meanwhile, the corresponding page code response is calculated to the front end, and the child node position is calculated by the father node position and the position code. If the target resource sub-node exists, the page code of the sub-node is directly responded to the client.
5. When a return operation occurs, the front end sends a request of the global unique identifier of the current page to the server end, the server end obtains a father node of the current page from the tree structure according to the global unique identifier, and page template resources are obtained through page URLs of the father node to respond to the front end. If the parent node does not exist, the default home page is just jumped to. If the father node is the root node, the business is exited.
6. When related page resources are deleted, put on shelf and the like, corresponding data in the tree structure can be directly operated, and the user is prevented from returning error resources when the operation returns.
