Detailed Description
Technical solutions in embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments, of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the disclosed embodiments without making any creative effort, shall fall within the protection scope of the present disclosure.
As used in this application and in the claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to include the plural, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" are intended to cover only the explicitly identified steps or elements as not constituting an exclusive list and that the method or apparatus may comprise further steps or elements.
Flowcharts are used herein to illustrate the operations performed by an apparatus or device according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, the various steps may be processed in reverse order or simultaneously, as desired. Meanwhile, other operations may be added to the processes, or a certain step or several steps of operations may be removed from the processes.
An HTML web page is a document written in the HTML language, and is a semi-structured data representation. The nodes contained in the HTML web page may form a node tree structure, and in the node tree, different hierarchies such as a parent node, a child node, a sibling node, and the like may be generated according to the interrelationship between the nodes. The designations of parent node, child node, sibling node, etc. are all relative to a particular node, and are not constant, and as the particular node changes, the designations of the nodes may change accordingly.
When a user browses a web page, the web page may be modified according to the need of the user. Specifically, the user may modify some attributes of the web page to obtain desired information or to achieve some special purpose. For example, a user may wish to modify or replace text or pictures locally in a web page to simulate and propagate a false message or post an unrealistic message. For another example, when a web page in a web page contains a watermark, a user may wish to obtain and use text, pictures or tables displayed on the web page by deleting or modifying the watermark.
Fig. 1 shows a schematic diagram of a user adding a watermark to a picture displayed on a web page of a website. As shown in fig. 1, a background picture may be added with a background (background) attribute of a Cascading Style Sheet (CSS) of a web page to add a watermark. However, in the implementation scenario shown in fig. 1, if the user wishes to delete the watermark on the web page, it is convenient to modify the background attribute of the cascading style sheet.
Fig. 2 shows a schematic source code diagram of the network page shown in fig. 1, and as shown in fig. 2, after a user calls the source code of the network page, the watermark can be changed and deleted by deleting the background (background) line of the source code shown in the block of fig. 2.
Therefore, an effective method and apparatus for monitoring web page changes is needed.
According to the embodiment of the disclosure, a method for monitoring change of a web page is provided, which can obtain a target node in the web page and a mount object to be mounted on the target node, and monitor the web page by monitoring the mount object of a child node of the target node, thereby effectively preventing the web page from being tampered. In addition, the method and the device for detecting the change of the network page can realize the timely monitoring of the change of the network page, thereby greatly improving the difficulty of stealing the information of the network page and ensuring the safety of the network page.
Next, a network page change monitoring method 300 according to an embodiment of the present disclosure will be described with reference to fig. 3.
First, according to step S301, at least one target node to be mounted is obtained in a web page.
According to the embodiment of the present disclosure, in this step, the number of the acquired target nodes to be mounted may be one or more. In one example, the target node may be found using a node identification of the target node. In another example, when the target node has different node classes, the target node may be found in batch by obtaining one or more node classes to which the target node belongs. For example, the node class may be selected by a class name (className) of the target node, so as to obtain the target node of a certain class or multiple classes of nodes. Alternatively, the target parameter may be used to indicate a manner of obtaining the target node, that is, the target parameter may indicate that the target node is found through a node identifier, or the target node is obtained through a node class name. The above-mentioned target node obtaining manner is only an example, and in practical application, any target node obtaining manner may be adopted, and any number of target nodes may also be obtained, which is not limited herein.
In step S302, for each target node, a mount object to be mounted to the target node is generated, and the mount object is mounted to the target node as a child node of the target node.
According to the embodiment of the present disclosure, the mount objects generated for each of the target nodes may be the same or different. For example, different mount objects may be generated for all the acquired target nodes, respectively; for another example, the same mount object may be generated for all the acquired target nodes; for another example, the same mount object may be generated for target nodes of the same node class, and different mount objects may be generated for target nodes of different node classes, which is not limited herein.
According to the embodiment of the disclosure, when a mounted object is generated, the attribute of the mounted object and the corresponding attribute value thereof can be determined. The attribute of the mounted object can be used for indicating the type of the mounted object and can also be used for indicating the style of the mounted object. For example, the type of the mounted object indicated by the attribute of the mounted object may include various expressions such as characters, pictures, animations, etc., and the style of the mounted object may include display parameters (such as brightness, contrast, transparency, etc.), tilt angle, size, number of mounted objects on each target node, etc. the mounted object may be a virtual object. Of course, the above description of the generation process of the mounted object is only an example, and in practical applications, the generation and expression modes of the mounted object may be arbitrarily selected according to different application scenarios of the mounted object, which is not limited herein.
After the mount object is generated, the mount object may be mounted on the corresponding target node by using the obtained correspondence between the target node and the generated mount object. When the mount object is mounted on the target node, the mount object becomes a child node of the target node. In one example, in the mounting process, the specific mounting position of the mounting object at the target node can be further determined by using the specified mounting parameters. For example, the mount parameter may be utilized to indicate that the mount object is mounted to, for example, an upper left, an upper right, a lower left, or a lower right of the target node. Alternatively, when the mount parameter does not indicate a mount position, the mount object may be mounted to the middle of the target node by default.
FIG. 4 illustrates an exemplary implementation of generating and mounting a mount object according to an embodiment of the disclosure. As shown in fig. 4, when the acquired at least one target node is a plurality of target nodes acquired according to a node class, in step S3021, a mount object for a target node of the node class may be generated for the node class. Optionally, the mount objects generated in this step for the same node class may be the same, or of course, may be different.
In step S3022, mount objects for the node class may be mounted on the plurality of target nodes in a batch. Optionally, the same mounting object for the same class can be simultaneously mounted on the target nodes of the same node class, so that batch mounting of the mounting objects on the target nodes is realized, system resources are saved, and mounting efficiency is improved.
Returning to step S303 in fig. 3, changes to the child nodes of the at least one target node may be monitored.
FIG. 5 illustrates an exemplary implementation of monitoring changes to children of the target node in accordance with an embodiment of the disclosure. As shown in fig. 5, in step S3031, at least one monitor may be added on a child node of the target node.
In step S3032, changes to child nodes of the target node may be monitored using the at least one monitor. In particular, the monitored changes to child nodes may include at least one of: changing a node attribute value (also called a mount object attribute value) of the child node, adding a new node attribute to the child node, deleting a node attribute of the child node, deleting the child node, mounting another child node on the child node, and the like.
In one embodiment of the present disclosure, a change observer (MutationObserver) in the web application programming interface (webApi) of H5 may be employed to monitor changes to child nodes. A change observer based monitoring mechanism may be used to monitor various events such as addition, deletion, attribute change, attribute addition, deletion, etc. of child nodes.
In another embodiment of the present disclosure, the monitoring may be performed by setting a monitor to poll the child nodes of the target node. Optionally, the child nodes of the target node may be polled according to a preset time period, so as to obtain the addition/deletion states of the child nodes and/or the addition, deletion, change, and the like of the attributes thereof.
According to an embodiment of the present disclosure, a runtime of the monitor may be set. When the runtime of the monitor is exceeded, the monitor may be logged off or the monitoring activity of the monitor may be suspended to minimize the impact of the monitor on system performance.
According to another embodiment of the present disclosure, changes to the at least one target node may also be monitored. FIG. 6 illustrates an exemplary implementation of monitoring changes to a target node according to an embodiment of the disclosure. As shown in fig. 6, in step S304, changes to the at least one target node may be monitored. Of course, the monitoring of the target node in step S304 may be performed simultaneously with the monitoring of the child nodes of the target node, or may be performed before or after the monitoring of the child nodes of the target node, which is not limited herein.
FIG. 7 illustrates an exemplary implementation of monitoring changes to the target node according to an embodiment of the disclosure. As shown in fig. 7, in step S3041, at least one monitor may be added on each target node.
In step S3042, changes to the target node may be monitored with the at least one monitor. In particular, the monitored changes to the target node may include at least one of: changing the node attribute value of the target node, adding a new node attribute to the target node, deleting the node attribute of the target node, deleting the target node, and adding a new child node to the target node.
In one embodiment of the present disclosure, a change observer (MutationObserver) in the web application programming interface (webApi) of H5 may be employed to monitor changes to the target node. The change observer-based monitoring mechanism can be used for monitoring various events such as addition, deletion, attribute change, attribute addition and deletion and the like of a target node.
In another embodiment of the present disclosure, the monitoring may be performed by setting a monitor to poll the target node. Optionally, the target node may be polled according to a preset time period, so as to obtain an addition/deletion state of the target node and/or addition, deletion, change, and the like of an attribute of the target node.
According to an embodiment of the present disclosure, a runtime of the monitor may be set. When the run time of the monitor is exceeded, the monitor may be logged off or monitoring activity of the monitor may be suspended to minimize the impact of the monitor on system performance.
FIG. 8 shows an exemplary implementation of a web page change monitoring method according to an embodiment of the disclosure. As shown in fig. 8, in step S305, in the case where the change is monitored, the change is discarded. In an embodiment of the present disclosure, the change may be a change of the target node and/or a child node. Specifically, previous changes may be discarded by setting a callback function on the monitor of the target node and/or child nodes, so that additions and deletions, changes/additions and deletions of attributes, and the like of the target node and/or child nodes are restored to the previous state.
According to the embodiment of the disclosure, an attribute monitor and/or a deletion monitor can be set for the child node of the target node based on the change observer, wherein the attribute monitor is used for monitoring the change of the attribute of the child node of the target node. Optionally, the attributes of the child nodes of the target node monitored by the attribute monitor may be all the attributes thereof, or may be one or more preset attributes thereof, which is not limited herein. In one example, a corresponding callback function may be set for the attribute monitor, and the callback function may be used to obtain specific content of attribute change and perform corresponding processing. For example, when the attribute monitor monitors that a certain attribute of a child node of the target node is deleted, a callback function may be used to increase a previously deleted attribute value; when the attribute monitor monitors that a new attribute is added to the child node of the target node, the new attribute can be deleted by using a callback function; when the attribute monitor monitors that a certain attribute value of the child node of the target node is changed, the attribute monitor can utilize a callback function to recover the attribute value before the change of the changed item.
The deletion monitor set for the child node of the target node may be used to monitor a deletion behavior of the child node of the target node or a node addition behavior on the child node. In one example, the deletion monitor may be provided with a corresponding callback function, which may be used to perform corresponding processing on the child nodes of the deleted/added target node and their associated nodes. For example, when the deletion monitor monitors that the child node of the target node is deleted, the deleted child node of the target node may be copied and all the attributes thereof may be re-assigned to generate a new child node; when the deletion monitor monitors that the child node of the target node is mounted with a new child node, the mounted new child node can be deleted.
According to the embodiment of the disclosure, an attribute monitor and/or a deletion monitor may be further provided for the target node based on the change observer, wherein the attribute monitor is used for monitoring the change in the attribute of the target node. Optionally, the attribute of the target node monitored by the attribute monitor may be all the attributes thereof, or may be one or more preset attributes thereof, which is not limited herein. In one example, a corresponding callback function may be set for the attribute monitor, and the callback function may be used to obtain specific content of attribute change and perform corresponding processing. For example, when the attribute monitor monitors that a certain attribute of the target node is deleted, a callback function can be used to increase the value of the attribute which is deleted previously; when the attribute monitor monitors that a new attribute is added to the target node, a callback function can be used for deleting the new attribute; when the attribute monitor monitors that a certain attribute value of the target node is changed, the attribute monitor can restore the attribute value before the change of the changed item by using a callback function.
The deletion monitor configured for the target node may be configured to monitor deletion/addition behavior of the target node and its associated child nodes. In one example, a corresponding callback function may be set for the deletion monitor, and the callback function may be used for performing corresponding processing on the deleted/added target node and its related child nodes. For example, when the deletion monitor monitors that the target node is deleted, the deleted target node may be copied and all the attributes thereof may be re-assigned to generate a new target node; when the deletion monitor monitors that the target node is mounted with a new child node, the mounted new child node can be deleted.
Fig. 9 illustrates an exemplary implementation of a web page change monitoring method according to an embodiment of the disclosure. As shown in fig. 9, in step S306, in the case that the change is monitored, the monitored change is reported. In an embodiment of the present disclosure, the change may be a change of the target node and/or a child node. Optionally, when the change behavior of the target node and/or the child node is monitored, whether to report to the server or whether to warn may be determined according to the specific nature and times of the behavior.
Fig. 10 is a schematic diagram illustrating a specific example of a web page change monitoring method according to an embodiment of the present disclosure. In fig. 10, the mounted object may be a watermark.
As shown in fig. 10, in step S1001, in the web page, a target node to be mounted is acquired. As described above, in this embodiment, a target node of a certain class may be obtained according to the class name of the target node to mount the same watermark.
In step S1002, for each target node, a watermark to be mounted to the node class target node is generated, and the watermark is mounted to the target node as a child node of the target node.
In this step, one same watermark pattern may be generated as a mounting object for the target node of the specific node class. In particular, the type and style of the watermark may be set by the attributes of the mounted object. In this embodiment, the watermark may be a picture with a transparency of 50% and an inclination angle of 45 degrees.
The generated watermarks may then be mounted to each target node having a particular node class, with the mounted watermarks acting as children of the target node.
In step S1003, an attribute monitor is set for the watermark.
In this step, an attribute monitor is provided for the watermark by using the change observer of H5, and is used to monitor the change of the attribute of the watermark. When the attribute monitor monitors that a certain attribute of the watermark is deleted, a callback function can be used for increasing the value of the attribute which is deleted previously; when the property monitor monitors that a property of the watermark is changed (e.g., the transparency setting is changed to 100%), a callback function may be used to recover the property value of the changed item (changing the transparency of the watermark back to 50%).
In step S1004, a deletion monitor is set for the target node on which the watermark is mounted.
In this step, a deletion monitor may be set for the target node on which the watermark is mounted by using the change observer of H5, and the deletion monitor is used to monitor the deletion behaviors of the child node on which the watermark is located and the mounted target node. When the deletion monitor monitors that the watermark or the mounted target node is deleted, the deleted watermark or the mounted target node can be copied, and all attributes of the deleted watermark or the mounted target node are re-assigned to generate a new watermark or a new target node.
In the steps S1001 to S1004 described in fig. 10, the method for monitoring web page change according to the embodiment of the present disclosure is exemplarily described by taking a mount object as a watermark. In practical application, the method in the embodiment of the present disclosure may be adopted for monitoring a web page for different mounted objects, which is not limited herein.
According to the embodiment of the disclosure, the target node in the web page and the mount object to be mounted on the target node can be acquired, and the web page is monitored by monitoring the mount object of the child node of the target node, so that the web page is effectively prevented from being tampered. In addition, the network page change detection method can realize the timely monitoring of the network page change, thereby greatly improving the difficulty of stealing the network page information and ensuring the security of the network page.
Next, a web page change monitoring apparatus 1100 according to an embodiment of the present disclosure will be described with reference to fig. 11.
As shown in fig. 11, the network page change monitoring apparatus 1100 according to the embodiment of the present disclosure includes an obtaining unit 1110, a mounting unit 1120, and a child node monitoring unit 1130.
First, the obtaining unit 1110 obtains at least one target node to be mounted in a web page.
According to the embodiment of the present disclosure, the target node to be mounted acquired by the acquiring unit 1110 may be one or more. In one example, the node identification of the target node may be utilized to find the target node. In another example, when the target node has different node classes, the target node may be searched in bulk by obtaining one or more node classes to which the target node belongs. For example, the node class may be selected by a class name (className) of the target node, so as to obtain the target node of a certain class or multiple classes of nodes. Alternatively, the target parameter may be used to indicate a manner of obtaining the target node, that is, the target parameter may indicate that the target node is found through a node identifier, or the target node is obtained through a node class name, and the like. The above-mentioned target node obtaining manner is only an example, and in practical application, any target node obtaining manner may be adopted, and any number of target nodes may also be obtained, which is not limited herein.
The mount unit 1120 generates, for each target node, a mount object to be mounted to the target node, and mounts the mount object to the target node as a child node of the target node.
According to an embodiment of the present disclosure, the mount unit 1120 may include: a generating subunit 1121 configured to generate a mount object. The mount objects generated by the generating subunit 1121 for each of the target nodes may be the same or different. For example, different mount objects may be generated for all the acquired target nodes, respectively; for another example, the same mount object may be generated for all the acquired target nodes; for another example, the same mount object may be generated for target nodes of the same node class, and different mount objects may be generated for target nodes of different node classes, and the like, which is not limited herein.
According to the embodiment of the present disclosure, when the generating subunit 1121 generates a mount object, attributes of the mount object and corresponding attribute values thereof may also be determined. The attribute of the mounted object can be used for indicating the type of the mounted object and can also be used for indicating the style of the mounted object. For example, the type of the mounted object indicated by the attribute of the mounted object may include various expressions such as characters, pictures, animations, etc., and the style of the mounted object may include display parameters (such as brightness, contrast, transparency, etc.), tilt angle, size, number of mounted objects on each target node, etc. the mounted object may be a virtual object. Of course, the above description of the generation process of the mounted object is only an example, and in practical applications, the generation and expression modes of the mounted object may be arbitrarily selected according to different application scenarios of the mounted object, which is not limited herein.
After the mount object is generated, the mount subunit 1122 in the mount unit 1120 may mount the mount object on the corresponding target node using the obtained correspondence relationship between the target node and the generated mount object. When the mount object is mounted on the target node, the mount object becomes a child node of the target node. In one example, during the mounting process, mounting subunit 1122 can further utilize specified mounting parameters to determine a specific mounting location of the mounted object at the target node. For example, a mount parameter may be utilized to indicate that a mount object is mounted to, for example, an upper left, an upper right, a lower left, or a lower right of the target node. Alternatively, when the mount parameter does not indicate a mount position, the mount object may be mounted to the middle of the target node by default.
In an embodiment of the present disclosure, when the obtained at least one target node is a plurality of target nodes obtained according to a node class, the generating sub-unit 1121 may generate a mount object for the target node of the node class for the node class. Alternatively, the mount objects for the same node class generated by the generating sub-unit 1121 may be the same, and certainly may be different.
Subsequently, the mount subunit 1122 can mount objects for the node class on the plurality of target nodes in batch. Optionally, the same mounting object for the same class can be simultaneously mounted on the target nodes of the same node class, so that batch mounting of the mounting objects on the target nodes is realized, system resources are saved, and mounting efficiency is improved.

Optionally, the child node monitoring unit 1130 may include an adding child unit 1131, configured to add at least one monitor on a child node of the target node.
The child node monitoring unit 1130 may further include a child node monitoring subunit 1132 for monitoring changes to child nodes of the target node using the at least one monitor. Specifically, the change to the child node monitored by the child node monitoring subunit 1132 may include at least one of: changing a node attribute value (also called a mount object attribute value) of the child node, adding a new node attribute to the child node, deleting a node attribute of the child node, deleting the child node, mounting another child node on the child node, and the like.
In one embodiment of the present disclosure, a change observer (MutationObserver) in the web application programming interface (webApi) of H5 may be employed to monitor changes to child nodes. A change observer-based monitoring mechanism can be used to monitor various events such as addition, deletion, attribute change, attribute addition and deletion of child nodes.
In another embodiment of the present disclosure, the monitoring may be performed by polling the child nodes of the target node through the set monitor. Optionally, the child nodes of the target node may be polled according to a preset time period, so as to obtain the addition/deletion states of the child nodes and/or the addition, deletion, change, and the like of the attributes of the child nodes.
According to an embodiment of the present disclosure, a runtime of the monitor may be set. When the run time of the monitor is exceeded, the monitor may be logged off or monitoring activity of the monitor may be suspended to minimize the impact of the monitor on system performance.
According to another embodiment of the present disclosure, the target node monitoring unit 1140 in the device 1100 for monitoring web page changes may also monitor changes to the at least one target node. Of course, the monitoring of the target node may be performed simultaneously with the monitoring of the child nodes of the target node, or may be performed before or after the monitoring of the child nodes of the target node, which is not limited herein.
The adding subunit 1141 in the target node monitoring unit 1140 may add at least one monitor on each target node.
A target node monitoring subunit 1142 in the target node monitoring unit 1140 may monitor changes to the target node with the at least one monitor.

In one embodiment of the present disclosure, a change observer (MutationObserver) in the web application programming interface (webApi) of H5 may be employed to monitor changes to the target node. The change observer-based monitoring mechanism can be used for monitoring various events such as addition, deletion, attribute change, attribute addition and deletion and the like of a target node.
In another embodiment of the present disclosure, the monitoring may be performed by setting a monitor to poll the target node. Optionally, the target node may be polled according to a preset time period, so as to obtain an addition/deletion state of the target node and/or addition, deletion, change, and the like of an attribute of the target node.
According to an embodiment of the present disclosure, a runtime of the monitor may be set. When the run time of the monitor is exceeded, the monitor may be logged off or monitoring activity of the monitor may be suspended to minimize the impact of the monitor on system performance.
According to the embodiment of the present disclosure, the web page change monitoring apparatus 1100 may further include: a change discarding unit 1150 configured to discard the change if the change is monitored. In an embodiment of the present disclosure, the change may be a change of the target node and/or a child node. Specifically, the previous change can be abandoned by setting a callback function to the monitor of the target node and/or the child node, so that the addition and deletion of the target node and/or the child node, the change/addition and deletion of the attribute, and the like are restored to the previous state.
According to the embodiment of the disclosure, an attribute monitor and/or a deletion monitor can be set for the child node of the target node based on the change observer, wherein the attribute monitor is used for monitoring the change of the attribute of the child node of the target node. Optionally, the attributes of the child nodes of the target node monitored by the attribute monitor may be all the attributes thereof, or may be one or more preset attributes thereof, which is not limited herein. In one example, a corresponding callback function may be set for the attribute monitor, and the callback function may be used to obtain specific content of attribute change and perform corresponding processing. For example, when the attribute monitor monitors that an attribute of a child node of the target node is deleted, a callback function may be used to increase a previously deleted attribute value; when the attribute monitor monitors that a new attribute is added to the child node of the target node, the new attribute can be deleted by using a callback function; when the attribute monitor monitors that a certain attribute value of the child node of the target node is changed, the callback function can be used for recovering the attribute value before the change of the changed item.
The deletion monitor configured for the child node of the target node may be configured to monitor a deletion behavior of the child node of the target node or a node addition behavior on the child node. In one example, the deletion monitor may be provided with a corresponding callback function that may be used to perform corresponding processing on the child nodes of the deleted/newly added target node and their associated nodes. For example, when the deletion monitor monitors that the child node of the target node is deleted, the deleted child node of the target node may be copied and all the attributes thereof may be reassigned to generate a new child node; when the deletion monitor monitors that the child node of the target node is mounted with a new child node, the mounted new child node can be deleted.
According to the embodiment of the present disclosure, an attribute monitor and/or a deletion monitor may be further provided for a target node based on the change observer, wherein the attribute monitor may be used for monitoring a change in an attribute of the target node. Optionally, the attribute of the target node monitored by the attribute monitor may be all the attributes thereof, or may be one or more preset attributes thereof, which is not limited herein. In one example, a corresponding callback function may be set for the attribute monitor, and the callback function may be used to obtain specific content of attribute change and perform corresponding processing. For example, when the attribute monitor monitors that an attribute of the target node is deleted, a callback function may be used to increase a previously deleted attribute value; when the attribute monitor monitors that a new attribute is added to the target node, the new attribute can be deleted by using a callback function; when the attribute monitor monitors that a certain attribute value of the target node is changed, the attribute monitor can utilize a callback function to recover the attribute value before the change of the changed item.
The deletion monitor configured for the target node may be configured to monitor deletion/addition of the target node and its associated child nodes. In one example, a corresponding call-back function may be set for the deletion monitor, and the call-back function may be used to perform corresponding processing on the deleted/added target node and its associated child node. For example, when the deletion monitor monitors that the target node is deleted, the deleted target node may be copied and all the attributes thereof may be re-assigned to generate a new target node; when the deletion monitor monitors that the target node is mounted with a new child node, the mounted new child node can be deleted.
According to the embodiment of the present disclosure, the web page change monitoring apparatus 1100 may further include: a reporting unit 1160 configured to report the monitored change if the change is monitored. In an embodiment of the present disclosure, the change may be a change of the target node and/or a child node.
