Description
Technical field
The invention belongs to the Computer Applied Technology field, be specifically related to a kind ofly resolve and script is dynamically carried out and combined the page is static, hang down the method for the quick structure of interaction network page dynamic view.
Background technology
The early stage web page only simply comprises contents such as some texts and picture, along with the development of web technology in recent years, the webpage personnel that write usually utilize some embedded link and in conjunction with the script operation, in a kind of mode that need not user interactions the how active element and the content of Geng Duo excellence are shown in the page.
Embedded link is the special hyperlink form that a class has the src attribute in the html page, be characterized in, when browser access has the page of embedded link, need not the user clicks, the content that link is pointed to will be loaded automatically, as have the src attribute＜iframe,＜frame what point to is an embedded page,＜script src points to is an embedded script file.Script in the page is as the instant run time version of a kind of client, the surfing and the interaction capabilities of webpage have been improved greatly, make and usually generating the relation that has realized a kind of real-time between webpage and the user some embedded link and it is written into the page by dynamic execution of script.
The present invention takes out the notion of webpage dynamic view, and it is during corresponding to user to access pages, and browser loads the hierarchical chart of the embedded document that embedded link points to automatically.As shown in Figure 1, during user to access pages X, even do not have further alternately, all embedded documents all can load or carry out by viewed device automatically among the figure.Webpage has brought the user a kind of more enriching experiences by dynamic view, yet has brought challenge to a few thing also.For example the leak attack code of webpage Trojan horse may reside in optional position in the webpage dynamic view and loading and the execution automatically of viewed device, and the complete detection of carrying out webpage Trojan horse must be based on the webpage dynamic view; For example some public sentiments are analyzed, and also must come webpage is carried out comprehensive content analysis based on the webpage dynamic view.
During user to access pages, the dynamic view of this page can be finished automatic loading in browser.Therefore can adopt a kind of high interactively method to obtain the webpage dynamic view, behavior when promptly monitoring the browser browsing pages, capturing the user does not have all document access contents under the mutual situation, but this kind method often has bigger time cost and systematic cost.
Summary of the invention
The present invention conducts in-depth analysis to present page elements autoloading reason, purpose is to provide a kind of method for constructing lightweight webpage dynamic view, its with the page static resolve and script dynamically execution combine and simulate browser, can when taking less system resource, construct the webpage dynamic view apace.
For convenience of explanation, the present invention introduces following notion:
1. embedded link: the special hyperlink of a class that refers to contain the src attribute, what it was pointed is dissimilar embedded documents, as＜iframe 〉/＜frame the embedded page of class and＜script embedded script etc., embedded document need not the user and clicks and can load automatically by viewed device;
2. static inline link: the embedded link that in the page source file, indicates with the static labels form;
3. dynamic embedded link: dynamically carry out and the automatic embedded link that generates by script;
4. local script: at＜script〉and＜/script between content for script, for the embedded script that has src;
5. webpage dynamic view: when the page is accessed, the hierarchical chart that embedded link is loaded automatically (as accompanying drawing 1), it has following tripartite face feature:
A) embedded link documents pointed such as the webpage dynamic view embedded page that viewed device is written into automatically when accessed by the accessed page and this page, embedded script are formed;
B) embedded link in the webpage dynamic view or in the page source file, indicate or dynamically carry out and generate by script with the form of static labels;
C) the webpage dynamic view has certain hierarchical structure---and be that the embedded page equally also has embedded link.
In comprehensive 5 a), b), c) 3 points: the webpage dynamic view is during corresponding to user to access pages, and browser is to the automatic loading layer hierarchical structure chart of embedded document.The webpage dynamic view is a tree structure, and document wherein to be analyzed and embedded document are as nodal set, and quoting between the document-relation of being cited is as the limit, and document to be analyzed is the root node of tree.During the user capture page, all viewed device of all embedded documents in this page dynamic view loads in order automatically.
The present invention is by low interactively simulation browser, all embedded documents that are written into and quote-be cited relation when analyzing the viewed device visit of the page, thus construct the dynamic view of webpage.Main thought is dynamically to carry out the embedded link of obtaining in the current page by static the parsing in conjunction with script of the page, come the embedded page of further recursive analysis by certain strategy, corresponding webpage dynamic view when finally constructing the viewed device visit of the page.
The low interaction network page dynamic view fast construction method that the present invention proposes mainly comprises following step:
(1) page to be analyzed is appointed as current page
(2) come current page is carried out local script parsing and static inline link identification by the static parsing of the page, its concrete disposal route is as follows:
A) local script is resolved: extract local script, it is pending to transfer to step (3)
B) static inline link identification, identify all static inline links step of going forward side by side and carry out following operation:
I. with the static inline script that identifies, it is pending to transfer to step (3)
Ii. with the static inline page that identifies, it is pending to transfer to step (5)
(3) be core with the script executing engine, carry out script and dynamically carry out the dynamic embedded link that identifies current page, mainly contain following two aspect work:
A) carry out the DOM simulation, with its context environmental as script executing, it mainly is divided into following two parts:
I. offer the application programming interfaces (API) of script with script simulation browser
Ii. construct automatically and the corresponding dom tree of the page (DocumentObject Model, i.e. DOM Document Object Model) with script simulation browser
B) dynamically embedded link identification: go forward side by side and one go on foot and carry out following processing loading the embedded link that captures dynamic generation in the relevant crucial function automatically with embedded link:
I. the script that identifies is carried out in step (3) immediately
Ii. the dynamic embedded page that identifies is transferred to step (5) and is handled
(4) step (2) and step (3) have analyzed the static inline link and the dynamic embedded link of current page, the document that these embedded link indicate constitutes an embedded collection of document, and each document in current page and the embedded collection of document is quoted and the relation of being cited
(5) analyze the embedded page of current page by certain embedded page recursive analysis strategy: the dynamic embedded page that the static inline page that (2)-b)-ii is analyzed and (3)-b)-ii analyze, be assigned therein as current page one by one, and get back to step (2) and analyze
(6), finish page dynamic view structure according to each resulting embedded collection of document of step (4) with quote-be cited relation.
Advantage of the present invention and good effect are as follows:
1. resolve and script is dynamically carried out combination the page is static, quote-be cited relation when the viewed device of multianalysis page-out is visited between all embedded documents that are written into and each document.
2. the low interactive mode of lightweight is simulated browser, finishes the structure of page dynamic view with less time cost and less systematic cost.
