Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Currently, when sharing information, application software on the intelligent mobile device directly shares the information, for example, if the information shared by a user is in a picture in an original format, the information shared by the user is in a picture; the original format is a character, and the shared format is the character; the original format is a web page, and what it shares is the URL address of the web page. The sharing results in that when other users want to open the webpage information that a user wants to share, the original webpage needs to be opened through the URL address. This results in the user not being able to view the shared content solely from the displayed presentation of the shared information. Meanwhile, the user may only want to share part of the content on the webpage, but not all the content to other users, but the current information sharing mode cannot be achieved. Meanwhile, the user can only share the information the user wants to share.
In order to facilitate understanding of the embodiment, a detailed description is first given of a webpage information propagation method disclosed in the embodiment of the present invention, and the method can be applied to an intelligent mobile terminal, in particular to an intelligent mobile terminal using an android system, for example, application software installed in a mobile phone, a tablet computer, and the like. The method and the device are used for converting the shared webpage information which the user wants into the picture, and further sharing the user information.
Referring to fig. 1, a method for propagating web page information provided by the embodiment of the present invention includes:
s101: and acquiring the content of a preset area on the webpage as sharing information according to a triggering instruction of a user.
In a specific implementation, a user needs to select information that the user wants to share from a webpage. Generally, a web page provides a user with a selected function by which the user can select a predetermined area on the web page. The predetermined area may include: the number of the predetermined area may be only one or a plurality of the characters and/or pictures. After a user selects the content on the webpage and further forms a preset area, the sharing function of the terminal is triggered, so that the terminal generates a corresponding trigger instruction. And the terminal is triggered according to the trigger instruction, and automatically acquires the content of the preset area on the webpage as sharing information.
Taking an android system as an example: the control used by the android system to load the webpage on the interface is Webview. The content of the predetermined area to be obtained is the content in the Webview, but actually, the Webview does not provide an interface for obtaining the selected content, and even does not provide an interface for obtaining the internal content thereof, so that directly obtaining the content of the predetermined area cannot be realized. However, in Webview, an interface is provided for Java (programming language of android system) to interact with its content JS (JavaScript, a high-level programming language that is a dynamic type through interpretive execution, object-oriented transliteration language), so that the content of a predetermined area in a web page can be acquired through JS.
In the process that Java acquires the content in the Webview through JS, Java is required to send a data calling instruction to JS, and JS is informed to call the content in a preset area from the Webview. After the JS successfully calls the content of the predetermined area from the Webview, Java is notified so that the Java receives the content of the predetermined area called by the JS.
In order to implement the above process, firstly, a callback function for which JS is written on the Java side and data is successfully obtained is written, for example, the callback function may be named as getWebData, and a parameter of the callback function is a character string format of the page data obtained by the JS segment. Secondly, the callback function needs to be registered in the JS through the Webview interface, so that the JS can use the callback function. For example, an addJavascript interface method of webview can be called, and the parameter is a Java-end interface method which is called by adding JS. Finally, the interface that the JS is called by the Jaca end needs to be realized: since the sharing logic is actually invoked by a Java (android system) end, the Java end needs to first notify JS to Webview to acquire the content of the predetermined area. Webview provides a loadUrl method to call the JS code, and the parameter of the loadUrl method is the character string of the JS code. In addition, since the interface function used by Java is different in different android versions, considering the adaptation problem, the interface is changed to evaluateJavascript above android 4.4, so that it is necessary to judge that the version of android is greater than 4.4 by executing build.
In addition, it should be noted that the above method for obtaining the content of the predetermined area on the web page implemented in the android system is only an example, and in other systems, or when the android system changes the relevant functions used by the android system, if the Webview provides other interface functions, the JS code is also called by using other interface even functions, and specific setting may be specifically performed according to actual situations, and is not limited herein.
Specifically, referring to fig. 2, an embodiment of the present invention provides a specific method for acquiring content in a predetermined area on a web page as shared information, including:
s201: acquiring the content of a currently activated selected area of a webpage; and taking the activation selection area as the predetermined area.
S202: and acquiring a range object corresponding to the content of the activation selection area.
S203: a content node object is created and populated with the range object.
S204: converting the content node object filled with the scope object into a character string; and using the character string as sharing information.
In the specific implementation, when the content in the webpage is selected, the selected content is directly acquired.
Still taking the android system as an example, to obtain the content of a predefined area of a web page, a Selection object of the web page is first obtained, which represents the currently active Selection area, i.e. the highlighted text block, and/or other elements of the document where the user may perform certain operations. A typical use of the Selection object is as an input by the user, so that the system recognizes which part of the document the user is processing, or as a result of an operation output to the user, where the Selection object is obtained for subsequent obtaining of content selected by the user on the web page, and the Selection object can be obtained by using the window.getselection () function of JS code in web development, but considering that the implementation of different versions of android Webview may be different, in order to maintain compatibility, the window.document.getselection may be called as well, which method can obtain content selected by the current activation of the web page, and which function is used.
In the above process, only the content of the currently activated selected area of the web page is obtained, and actually, the system cannot generate a picture by using the currently activated selected content, so that a range object corresponding to the activated selected content needs to be obtained. The scope object is actually HTML code corresponding to the contents of the currently activated selected region.
Taking the android system as an example, obtaining the Selection object and calling the method getrange at (0) can be used to obtain the scope object, and the scope object is named range here. After the scope object of the content is obtained, an html node object needs to be created to store the content, for example, a div tag may be used, div represents a document content tag, a window.
After the content range object is obtained, copying one part of the internal content of the content range object to be filled in the content for the use of a subsequent java layer, calling an appndchild method of the content to add the content to the content, and calling a cloneContents method of the range object to copy the content by the range object. Meanwhile, because the content is only a tag object, the content needs to be converted into a character string to be convenient for the java layer to use, and the innerHTML member can be directly called to return the character string content.
The content of the preset area on the webpage can be obtained through the method. It should be noted that, in different terminal systems, because there are many differences in system architecture, constructed functions, web page display, etc., there are other methods for obtaining the content of the predetermined area on the web page, and the specific setting can be made according to the actual situation.
S102: and forming the sharing information into a sharing picture.
In a specific implementation, since the content of the predetermined area is already acquired as the sharing information, the sharing information can be subsequently combined into a sharing picture.
Specifically, referring to fig. 3, an embodiment of the present invention further provides a specific method for forming a shared picture from shared information, where the method includes:
s301: generating a content view according to the character string according to a preset typesetting style;
in a specific implementation, since the content node object filled with the range object is already converted into a character string in S204, Java can call the character string. The content contained in the character string is an HTML code of the shared information, so that the style customization operation can be performed on the shared information, namely, a new Webview is used to convert the HTML code corresponding to the shared information into a corresponding view to display the selected shared information or the shared information which a user wants to share, the shared information is displayed on a WEB page, and simultaneously a typesetting style which needs to be set can be used to typeset or edit the content displayed on the WEB page, for example, in an android system, the style of the webpage is generally expressed by a css file, so that a set of css can be defined by self to be put in assets to change the style of the new Webview, thereby changing the style of subsequent production pictures, and the files such as the custom styles can be stored in an assets resource directory to be read, and finally a content view is generated, and the content view is really a new webpage, the web page contains the shared content that the user wants to share.
It should be noted that the layout style of the shared information in the content view may be different from the layout style in the original webpage.
S302: and converting the content view into a view picture, and taking the view picture as the sharing picture.
The method specifically includes, when converting a content view into a view picture:
the width and height of the newly created content view are obtained.
And creating an empty picture file as an object of the target picture according to the width and the height of the read content view.
And drawing the content of the content view onto the target picture to form a view picture.
Still take the android system as an example: and directly calling getWidth () method, and obtaining the width and height of the Webview by the getHeight () method. Creating an empty bitmap (bitmap file) object as an object of the target picture by calling a bitmap provided by an android system. However, because the view of the android can only draw on the Canvas object, and cannot directly draw a view on the bitmap object, a Canvas object needs to be created through the bitmap, the bitmap is the most parameter of the construction method, then the draw method of the Webview is called, the parameter is transferred to the Canvas object, and the Webview content is drawn on the bitmap.
S103: and sharing the sharing picture.
According to the webpage information spreading method provided by the embodiment of the invention, firstly, the content of the preset area is obtained from the webpage as the sharing information according to the triggering instruction of the user, then the sharing information forms the sharing picture, and finally the sharing picture is shared out.
Referring to fig. 4, an embodiment of the present invention further provides another method for propagating web page information, where on the basis of the foregoing several embodiments, before converting the content view into a view picture, the method further includes:
s401: acquiring a real path of an original picture in the webpage;
s402: judging whether the content view comprises a picture or not;
s403: if so, replacing the relative path of the picture in the content view with the real path corresponding to the picture obtained in advance.
In the specific implementation, since the picture included in the original webpage may be selected by the user as a part of the shared content, and the picture path displayed by the part of the picture in the HTML may be a relative path, after the view content is generated, the path of the part of the picture is accessed locally through the first-pair path, and thus the path of the part of the picture needs to be restored to the real path address.
Taking an android system as an example, when a real path of an original picture in a webpage needs to be acquired, firstly, an onLoadResource method of an original Webview is monitored, wherein the onLoadResource method is a callback of Webview loading resources, and absolute paths (namely real paths) are generated for resources of relative paths, so that a list of character strings is defined, and all paths of jpg,. png and. gif are stored.
The method includes the steps that a relative path of a picture in a new Webview is replaced by an absolute path, a shoulderceptrequest method monitored by a Webview state can be rewritten, all requests with hyperlinks in the Webview can be intercepted by the callback method, logic for url judgment is added in a shoulderceptrequest callback, whether the url of a current picture stores sub-content in a character String list is judged, whether the absolute path contains the relative path is judged only if the relative path is definitely a subset of the absolute path, for example, the relative path is "/abc.jpg", and the absolute path is http:// www.abc.com/abc.jj ", and a java String class contentions method can be called to judge, and when the pgs are judged to be the subset of the absolute path, the absolute path is covered by the absolute path.
