In order to more clearly illustrate the technical solutions in embodiments of the disclosure or the reference, the appended drawings needing to be used in description of the embodiments or the reference technology will be introduced simply in the following. Obviously, the drawings in the following description are only some embodiments of the disclosure, and for the person having ordinary skills in the art, other drawings may also be obtained according to these drawings under the premise of not paying out undue experimentation.
In the following the technical solutions in embodiments of the disclosure will be described clearly and completely in conjunction with the drawings in the embodiments of the disclosure. Obviously, the described embodiments are just a part of the embodiments of the disclosure, and not all the embodiments. Based on the embodiments in the disclosure, all the other embodiments obtained by the person having ordinary skills in the art under the premise of not paying out undue experimentation pertain to the scope protected by the disclosure.
Nowadays, for data acquisition in an APP (application), it is often needed for a developer to write code specifically for data acquisition and put it in a callback function which generates an event at the time of a specific operation on an interface. This will make the development process complicated, it is needed to consider a control to acquire data and write code in advance, and if the data acquisition points are increased or decreased later, it is necessary to rewrite the code and upgrade software so as to make the new code take effect on the APP, which lacks flexibility. In addition, some technical solutions employ a full buried point manner, that is, add a segment of processing code to all possibly acquired event point callbacks on the interface, and the developer has to take account of embedding of a data acquisition function in advance.
An embodiment of the disclosure provides a page data acquisition method, which, as shown in
S10, communication with a server is performed, and configuration information is obtained from the server, which configuration information includes control information.
It will be appreciated by the person having skills in the art that in the embodiment of the disclosure, the page data acquisition method is performed by a terminal device. Various applications may be installed on the terminal device, for example, a shopping class application, a webpage browser application, a search class application, an instant communication tool, a mailbox client, etc. The terminal device includes, but not limited to, a mobile phone, a tablet computer, a portable computer, a desktop computer, etc.
The terminal device may communicate with the server through a wired or wireless network.
S11, all the controls in a current page are traversed, and for each of the controls, it is judged whether the control is one indicated by the control information in the configuration information; and if yes, S12 is performed.
Therein, for the control, there is a text control, a picture control, a button control, a selection box control, an input box control, a progress bar control, etc.
All the controls in the current page may be traversed in a recursive manner.
With Android as an example, traversing all the controls in the current page may be to parse a view tree of the page and traverse all the views starting from DecorView (a root node) in the views. The number of child nodes may be obtained by a function getChildCount( ) then a view of a child node is obtained by a function getChildAt( ) and all the views of the page may be traversed in a recursive manner. Therein, it should be appreciated by the person having skills in the art that the control is a specific class of view. On this basis, if the information of a certain control is consistent with the control information in the configuration information, a listener is set for the control.
It may be understood that the control information included by the configuration information in the server shall be information of a control on which behavior data acquisition needs to be performed.
S12, a listener is set for the control.
It needs to be noted that, if a certain control is one indicated by the control information in the configuration information, a listener is set for the control, which is essentially to create a new listener to replace the existing listener and add in the new listener a behavior data acquisition function corresponding to the type of the control, of which the code will be preset in a program in advance. In addition to acquiring behavior data, the actions with which the new listener responds to an event will invoke an event response function of the original listener to accomplish the original functional logic of the control.
Therein, the behavior data acquisition function should be determined according to the type of the control. For example, for a button control, what is acquired is click behavior data; and for a selection box control, selection behavior data may be acquired, or click behavior data may also be acquired. When multiple kinds of behavior data may be acquired for a control, it is necessary to determine which kind of behavior data is to be acquired at the time of developing the program, and thus preset code knows what type of listener to use to replace the original listener (that is, which behavior data acquisition function is added). Once the acquisition action is defined, the acquisition function will be determined when a behavior takes place.
Since the code of the behavior data acquisition function does not need to be written in each event processing function, the behavior data acquisition is performed in a buried-point-free manner in the disclosure. Here, it further needs to be noted that, it is only necessary to add code at positions where a page shows and disappears when developing an APP in the disclosure. In particular, use of the buried-point-free manner to acquire behavior data needs to invoke an interface, and yet the places where the interface is invoked are the positions where a page shows and disappears.
S13, behavior data acquisition is performed on the control by the listener.
The embodiment of the disclosure provides a page data acquisition method. By storing configuration information including control information in a server, wherein the control indicated by the control information is one on which it is necessary to perform behavior data acquisition, it may be possible to set a listener only for the control indicated in the configuration information, to implement acquisition of behavior data, after a terminal device obtains the configuration information and when a user is browsing a current page. Based on this, since the behavior data acquisition function will be preset in a program in advance, and add it when a listener is set for a control, as compared to the buried point manner (i.e., in which code is written in an event processing function) employed in the reference, the disclosure does not need to add code when each control event is processed, which may reduce the complexity of the development process. When it is needed to update the listener for a control event, it is also no need to rewrite code and update software, and the operation is simple.
In an embodiment, as shown in
S14, parsing the configuration information and storing it locally.
That is, after the configuration information is parsed, it is stored in the terminal device.
In an embodiment, the control information includes a control ID, and further, may also include an associated control ID.
When a control ID is included the configuration information, if the ID of a control is consistent with the control ID in the configuration information, the control is one indicated by the control information in the configuration information.
When an associated control ID is further included in the configuration information, there will be a situation in which a certain control is associated with another control. For example, it may be such that one button control is associated with an edit box control, and based on this, it may be possible to perform click behavior acquisition on the button control and acquire the content inputted into the edit box. In an embodiment of the disclosure, by the server issuing the configuration information, the terminal dynamically monitors a control event. When the control information in the configuration information issued by the server includes an associated control ID, the event may be made to carry other control behavior data information.
In an embodiment, as shown in
The terminal device uploads the acquired behavior data to the server, and after the server stores it, subsequent analysis and processing may be performed.
In an embodiment, the configuration information further includes page information; and based on this, as shown in
On this basis, as shown in
Further, the obtaining the duration from entering to exiting the current page and a page name includes: obtaining the time to enter the current page and the page name.
Therein, the obtaining the time to enter the current page and the page name, as shown in
S161, in response to entering the current page, the time to enter the current page is recorded, the state of the current page is identified as visible, and page information including a page object and the page name of the current page is stored.
Exemplarily, the page information may be stored in a list. A page is divided into a main window page and a sub-window page affiliated to the main window. For example, under a certain Activity (an active page), there may exist multiple Fragments (part of the page), wherein the Activity is a main window, and a Fragment is a sub-window. When entering the Activity or a Fragment, the class name of the Activity or the
Fragment may be stored as a page name, and the current time is recorded. By taking the class name of the Activity or the Fragment as a page name, statistics on the Activity and the Fragment is implemented.
S162, when storing the page information, it is judged whether there is a main window page with a visible state in a current storage list; if yes, S163 is performed; otherwise, S164 is performed.
S163, the current page is taken as a sub-window page of the main window page with a visible state.
S164, the current page is taken as a main window page.
On this basis, the obtaining the duration from entering to exiting the current page, as shown in
S165, when the current page exits, it is judged whether the current page is a sub-window page; if yes, S166 is performed; otherwise, S167 is performed.
It may be understood that, if the current page is not a sub-window page, it is necessarily a main window page.
S166, the current time minus the time to enter the current page is taken as the duration from entering to exiting the current page, and the state of the current page is identified as invisible.
S167, for the current page and a sub-window page which is affiliated to the current page and of which the state is identified as visible, the current time minus the respective time of entry is employed as the durations from entering to exiting the respective pages, and the states of the current page and the sub-window page which is affiliated to the current page and of which the state is identified as visible are identified as invisible.
In an embodiment, as shown in
On this basis, the setting a listener for the control includes: if there is no record for the control, recording the control, and setting a listener for the control; if there is an existing listener for the control, replacing the existing listener with a new listener, which new listener is added a behavior data acquisition function corresponding to the type of the control on the existing listener, and if there is no listener for the control, setting a listener for the control, which listener obviously has the behavior data acquisition function corresponding to the type of the control; and if it is found that there is a record for the control, making no processing, that is, continuing to use the original listener.
Exemplarily, still taking the Android system as an example, when traversing all the controls in a page, if the ID of a certain control is the same as a control ID included in the configuration information, the control is one for which data acquisition needs to be performed. It may first be found whether there is a record for the control, and if there is no record for the control, the control is recorded, for example, recorded in a HashMap (Hash table), wherein a key may be an ID and a Value is a control itself, and the data acquisition function is added in the listen corresponding to the control. If it is found that there is a record for the control, no processing is performed, that is, the original listener continues to be used. Therein, if the control is recorded in the HashMap, then at the time of finding, the finding should also be performed in the HashMap.
In the embodiments of the disclosure, a control for which a listener is set is recorded, and before a listener needs to be set for a certain control, it is first found whether there is a record for the control, and if yes, there may be no need to set a new control again, which may avoid repetition.
Based on the forgoing, in an embodiment, the listener is set for the control by means of reflection and dynamic proxy.
In particular, a dynamic proxy is used to create a new listener, however, when creating the new listener, a parameter is needed, namely, the original listener, which original listener needs to be obtained using a reflection mechanism.
Exemplarily, with a button control as an example, an object obj1 with a fieldId of mListenerInfo may first be obtained using the reflection approach, then an object obj2 with a fielded of mOnClickListener of obj1 is obtained, an object obj3 of InvocationHandler is constructed using obj2, a proxy object of the original monitor is created using Proxy.newProxyInstance, and finally, the member mOnClickListener of mListenerInfo is set for the new proxy object by means of reflection, which realizes that a new monitor is used to replace the original monitor, and invocation of obj2 of the original monitor is kept in obj3 in addition to adding a new event processing logic, thereby implementing acquisition of a click event on the basis of the original functions.
An embodiment of the disclosure further provides a page data acquisition apparatus, as shown in
Therein, the control information may include a control ID and an associated control ID.
The control event monitor 20 is configured to traverse all the controls in a current page, and for each of the controls, judge whether the control is one indicated by the control information in the configuration information, and if yes, set a new listener for the control, which new listener is the original listener with a behavior data acquisition function corresponding to the type of the control added thereon.
Therein, all the controls in the current page may be traversed in a recursive manner.
With the Android system as an example, traversing all the controls in the current page may be to parse a view tree of the page and traverse all the views starting from DecorView in the views. The number of child nodes may be obtained by a function getChildCount( ), then a view of a child node is obtained by a function getChildAt( ) and all the views of the page may be traversed in a recursive manner. Therein, it should be appreciated by the person having skills in the art that the control is a specific class of view. On this basis, if the information of a certain control is consistent with the control information in the configuration information, a listener is set for the control.
It may be understood that the control information included by the configuration information in the server shall be information of a control on which behavior data acquisition needs to be performed.
It needs to be noted that, if a certain control is one indicated by the control information in the configuration information, a listener is set for the control, which is essentially to create a new listener to replace the existing listener and add in the new listener a behavior data acquisition function corresponding to the type of the control, of which the code will be preset in a program in advance. In addition to acquiring behavior data, the actions with which the new listener responds to an event will invoke an event response function of the original listener to accomplish the original functional logic of the control.
Therein, the listener may be set for the control by means of reflection and dynamic proxy. In particular, a dynamic proxy is used to create a new listener, however, when creating the new listener, a parameter is needed, namely, the original listener, which original listener needs to be obtained using a reflection mechanism.
The behavior data acquisition function should be determined according to the type of the control. For example, for a button control, what is acquired is click behavior data; and for a selection box control, selection behavior data may be acquired, or click behavior data may also be acquired. When multiple kinds of behavior data may be acquired for a control, it is necessary to determine which kind of behavior data is to be acquired at the time of developing the program, and thus preset code knows what type of listener to use to replace the original listener (that is, which behavior data acquisition function is added). Once the acquisition action is defined, the acquisition function will be determined when a behavior takes place.
The embodiment of the disclosure provides a page data acquisition apparatus. By storing configuration information including control information in a server, wherein the control indicated by the control information is one on which it is necessary to perform behavior data acquisition, it may be possible, after a terminal device obtains the configuration information through a communicator 10 and when a user is browsing a current page, to set a listener only for the control indicated in the configuration information by a control event monitor 20, wherein the new listener is added a behavior data acquisition function corresponding to the type of the control on the basis of the original listener, thereby implementing acquisition of behavior data. Based on this, since the behavior data acquisition-function will be preset in a program in advance, and add it when a listener is set for a control, as compared to the buried point manner (i.e., in which code is written in an event processing function) employed in the reference, the disclosure does not need to add code when each control event is processed, which may reduce the complexity of the development process.
In an embodiment, the configuration information further includes page information, and based on this, as shown in
On this basis, the page statistics device 30 obtaining the duration from entering to exiting the current page and a page name includes: the page statistics device 30 obtaining the time to enter the current page and the page name.
Therein, the page statistics device 30 obtaining the time to enter the current page and the page name includes: in response to entering the current page, recording the time to enter the current page, identifying the state of the current page as visible, and storing page information including a page object and the page name of the current page; when storing the page information, judging whether there is a main window page with a visible state in a current storage list, and if yes, taking the current page as a sub-window page of the main window page with a visible state, otherwise, taking the current page as a main window page.
Exemplarily, the page information may be stored in a list. A page is divided into a main window page and a sub-window page affiliated to the main window. For example, under a certain Activity, there may exist multiple Fragments, wherein the Activity is a main window, and a Fragment is a sub-window.
When entering the Activity or a Fragment, the class name of the Activity or the Fragment may be stored as a page name, and the current time is recorded. By taking the class name of the Activity or the Fragment as a page name, statistics on the Activity and the Fragment is implemented.
On this basis, after obtaining the time to enter the current page and the page name, the page statistics device 30 further obtains the duration from entering to exiting the current page.
Therein, the page statistics device 30 obtaining the duration from entering to exiting the current page includes: when the current page exits, judging whether the current page is a sub-window page; if yes, taking the current time minus the time to enter the current page as the duration from entering to exiting the current page, and identifying the state of the current page as invisible; and if no, for the current page and a sub-window page which is affiliated to the current page and of which the state is identified as visible, employing the current time minus the respective time of entry as the durations from entering to exiting the respective pages, and identifying the states of the current page and the sub-window page which is affiliated to the current page and of which the state is identified as visible as invisible.
In an embodiment, the control event monitor 20 is configured to, after judging that the control is one indicated by the control information in the configuration information, before setting a listener for the control, further find whether there is a record for the control; if there is no record for the control, record the control, and set a listener for the control; if there is an existing listener for the control, replace the existing listener with a new listener, wherein the new listener is added a behavior data acquisition function corresponding to the type of the control on the existing listener; and if there is no listener for the control, set a listener for the control, which listener obviously has the behavior data acquisition function corresponding to the type of the control; and if it is found that there is a record for the control, make no processing, that is, continue to use the original listener.
Exemplarily, still taking the Android system as an example, when traversing all the controls in a page, if the ID of a certain control is the same as a control ID included in the configuration information, the control is one for which data acquisition needs to be performed. It may first be found whether there is a record for the control, and if there is no record for the control, the control is recorded, for example, recorded in a HashMap, wherein a key may be an ID and a Value is a control itself, and the data acquisition function is added in the listen corresponding to the control. If it is found that there is a record for the control, no processing is performed, that is, the original listener continues to be used. Therein, if the control is recorded in the HashMap, then at the time of finding, the finding should also be performed in the HashMap.
In the embodiments of the disclosure, a control for which a listener is set is recorded, and before a listener needs to be set for a certain control, it is first found whether there is a record for the control, and if yes, there may be no need to set a new control again, which may avoid repetition.
In an embodiment, as shown in
In an embodiment, the communicator 10 is further configured to upload at least the acquired behavior data to the server. After the communicator 10 uploading the acquired behavior data to the server and the server storing it, subsequent analysis and processing may be performed.
Further, the communicator 10 may further upload the duration from entering to exiting the current page and the page name to the server.
An embodiment of the disclosure further provides a server, as shown in

Therein, the configuration information is stored in the form of an xml file or a json format data or the like.
The control information includes a control ID, and further, may also include an associated control ID.
When a control ID is included the configuration information, if the ID of a control is consistent with the control ID in the configuration information, the control is one indicated by the control information in the configuration information.
When an associated control ID is further included in the configuration information, there will be a situation in which a certain control is associated with another control. For example, it may be such that one button control is associated with an edit box control, and based on this, it may be possible to perform click behavior acquisition on the button control and acquire the content inputted into the edit box. In an embodiment of the disclosure, by the server issuing the configuration information, a terminal dynamically monitors a control event. When the control information in the configuration information issued by the server includes an associated control ID, the event may be made to carry other control behavior data information.
The request receiver 60 sends the configuration information to a page data acquisition apparatus when receiving a request for obtaining the configuration information sent by the page data acquisition apparatus.
Based on this, after a terminal device obtains the configuration information and when a user is browsing a current page, a new listener is set only for the control indicated in the configuration information, wherein the new listener is added a behavior data acquisition function corresponding to the type of the control on the basis of the original listener, thereby implementing acquisition of behavior data. Since the behavior data acquisition function will be preset in a program in advance, and add it when a listener is set for a control, as compared to the buried point manner (i.e., in which code is written in an event processing function) employed in the reference, the disclosure does not need to add code when each control event is processed, which may reduce the complexity of the development process.
