Embodiment
It is below in conjunction with the accompanying drawings and specific real to enable the above-mentioned purpose of the application, feature and advantage more obvious understandable Mode is applied to be described in further detail the application.
At present, more and more other kinds of third party softwares, such as instant message applications, download software, even input method Deng, all start by with the page access ability using web browser, realize some functions of its software, there is provided preferably use Experience at family.
The Webbrowser objects that the IE browser of Microsoft provides there are it is more the drawbacks of, such as:
The version of Webbrowser objects limits using and showing for many new page technologies always excessively;
Webbrowser is the weaker browser core of a security, easily triggers safety problem;
Webbrowser easily installs plug-in unit by various rogue softwares, and injecting codes, initiation much uses problem, for example closes Flash and java operations have been closed, have caused correlation function to fail.
It is above-mentioned existing for the Webbrowser kernels of IE in order to solve during third party software realizes web page browsing Various problems, this application provides a kind of method that web page browsing is realized using webkit.Wherein, the webkit is Chrome The core of browser, webkit are the browser engines (web browser engine) of an open source code.
But if directly realizing web page browsing using webkit cores in third party software, there are following defect:
Webkit core interfaces are complicated, and technical threshold is high, adds the technology that software realizes page browsing function using it Threshold;Webkit core codes are more, and dll (dynamic link library) is larger, adds the volume using its software;Browser version Renewal is rapid, directly can not accomplish quickly to use state-of-the-art technology comprising webkit cores, evade known security problem.
Based on this, the application does not use webkit cores directly, there is provided a kind of page browsing service of striding course Dll, any third party software can obtain page browsing ability on the system of such a dll services is mounted with, so as to simplify The technical threshold and complexity of the page are rendered using webkit.
Webkit is only responsible for completing html parsings and renders work, other work as a complete browser kernel Such as parsing of network connecting request, js, periphery packaging, after being required for third party software to realize, webkit could be worked normally.And Realize that a good http protocol stack and js resolver difficulty is huge, work is complicated.
The dll services of this page browsing in the application can be understood as an agency, and agency encapsulates network connection Request, js parsing, periphery packaging etc. work so that by these users be indifferent to again complexity part user is shielded; Also, agency also encapsulates simple interface to call several basic webkit browser operations.Third party software can lead to This dll services realization and the communication of webkit cores are crossed, user need to only provide url and window sentence for being used to carry the page Handle, it is possible to obtain a webpage for rendering completion.Completed since many work during web page browsing are all serviced by dll, Therefore the exploitation of third party software is simplified.
Flow, which is described in detail, to be realized to herein described method below by embodiment.
It is a kind of stream of the striding course Web browser method based on webkit cores described in the embodiment of the present application with reference to Fig. 1 Cheng Tu.
Step 101, dynamic link library is loaded by self defined interface;
The self defined interface includes external interface and internal interface, and dynamic link library can be loaded by external interface.
Dynamic link library (dll services) is supplied to third party software to use external interface, and third party software realizes this After a little simple external interfaces, it is possible to communicate with dynamic link library.
Dynamic link library additionally provides the page object export interface of Webkit kernels, these internal interfaces is in webkit The interface of the Webbrowser objects of similar IE derived from core, but specific interface number and to be significantly less than IE using complexity Webbrowser.Moreover, conventional method packaging webkit needs to realize hundreds of interfaces, but third party in the embodiment of the present application The interface number realized needed for software is considerably less, but several basic browser operations have all been included therein.
After third party software realizes the small numbers of self defined interface, dynamic link library is loaded by self defined interface Dll, specific loading method are as follows:
Registration table is accessed by self defined interface;
Search the store path of dynamic link library dll described in registration table;
The dynamic link library dll is loaded from the store path.
Step 102, the dynamic link library is called to create page object;
Pass through the internal interface for calling dynamic link library to provide, it is possible to realize the communication with Webkit kernels.
Wherein, page object is created using factory mode.Factory mode is exactly to be responsible for largely having common interface specially Class instantiation, and need not know it is the pattern that instantiate which class every time in advance.It defines one and is used for establishment pair The interface of elephant, determines which class instantiated by subclass.
Specific sub-step is as follows:
Sub-step 1, calls the dynamic link library to obtain factory method;
Sub-step 2, calls the factory method to create factory's object;
Sub-step 3, calls factory's Object Creation page object.
Step 103, by calling the page creation method in the page object, notice webkit browsers create the page Window, and complete rendering and showing for content of pages in the page window.
Specific sub-step is as follows:
Sub-step 1, constructing variable object, and in the parameter object fill target access network address and window handle;
Sub-step 2, the page creation side in the page object is passed to using the parameter object after filling as parameter value Method;
Sub-step 3, by the page creation method after call parameters assignment, notice webkit browsers create page window Mouthful, and complete rendering and showing for content of pages in the page window.
Page creation method is provided in page object, parameter is equipped with this method, parameter assignment is the net of target access Behind location and window handle, by calling this method to be transmitted to webkit kernels, webkit with webkit kernel communications, parameter value Kernel creates page window according to parameter value access target network address, completes rendering and opening up for content of pages in the page window It is existing.
Finally, the related readjustment of browser can also notify third party software by corresponding function call.
The above is explained in detail below by a specific example.
The content and usage of interface are as follows:
One factory method is provided, is called for third party software:
extern"C"{
DLL_INTERFACE WebAppFactory*GetWebAppFactory();
};
Third party software can load dll services (dynamic link library) by LoadLibrary functions, and pass through GetProcAddress functions obtain factory method GetWebAppFactory, and create factory Object Web AppFactory, into And a page object WebAppTabWrapper is obtained, its interface is as follows:
After third party software obtains WebAppTabWrapper objects, by calling the Create methods of object offer, Notify the WEB-browsing services of webkit kernels to create a new page, and call the notice service of Navigate methods to be led Boat operation, Stop, Reload, GoBack, GoForward then provide basic page forward-reverse, stop loading and refresh work( Energy.Third party software is when no longer needing browsing pages, by calling Destroy methods to destroy page object.
Specifically, it can also comprise the following steps:
By calling the Navigate methods in the page object, notice webkit browsers in the page window into Row page jumping operation.For example, in the page window newly created, the content for the welcome page that initial access target network address is shown, Then by calling Navigate methods, real homepage can be jumped to from welcome page, but no longer creates new page window Mouthful, redirecting for content of pages is only carried out in same page window.
By calling the Stop methods in the page object, notice webkit browsers stop the page in the page window Content is rendered and showed.
By calling the Reload methods in the page object, notice webkit browsers refresh in the page window Content of pages.
By calling the GoBack methods in the page object, notice webkit browsers carry out in the page window Page back operates;
By calling the GoForward methods in the page object, notice webkit browsers are in the page window Carry out page forward operation.
By calling the Destroy methods in the page object, notice webkit browsers destroy the page object.
After third party software realizes as above interface, the related readjustment of webkit browsers will pass through corresponding function call Notify third party software.Specific workflow is as shown in Figure 2:
Reference Fig. 2, is the stream of the striding course Web browser method based on webkit cores described in another embodiment of the application Cheng Tu.
Step 201, third party software realizes WebAppUIDelegate interfaces;
The WebAppUIDelegate interfaces are the external interfaces that dll services are supplied to that third party software uses,As One preferred embodiment interfaceSpecificallyGroundProvide following interface function:
Each interface function is described as follows:
OnHandleAccelerator functions provide shortcut callback method, and notice third party software user presses one Group shortcut;
OnOpenURL functions, which provide, opens page callback method, and notice third party software user attempts to open a new page Face, third party software can allow or forbid;
OnTitleChange functions provide title (title) and change callback method, the current window of notice third party software Title words are changed;
OnStatusTextChange functions provide status bar and change callback method, the current window of notice third party software Status bar text is changed;
OnNavigateComplete2 functions provide navigation and finish callback method, and notice third party software navigation is completed;
OnNavigateError functions provide navigational error callback method, notify third party software navigational error;
OnQuit functions, which provide, exits callback method, and notice third party software user closes current page or renders clothes Business is exited because of certain reason;
OnUpdateTargetUrl functions provide target url renewal callback methods, the current target of notice third party software Url is changed;
OnGetCurrentUrlRsp functions provide obtains current url callback methods, and notice third party software is current url;
OnCrashReport functions provide collapse callback method, and notice third party software page access service is collapsed Burst;
OnReportMainWindow functions provide main window callback method, notify the main window of third party software current page Mouthful;
OnWebAppJsCall functions provide js callback methods, notify third party software, and page request performs an outside Js is called.
Step 202, by the registry key of agreement, the path where Webapp_proxy.dll is found;
Wherein, the Webapp_proxy.dll is dynamic link library, i.e. dll services;
Step 203, Webapp_proxy.dll is loaded;
If loaded successfully, that is, continue step 204;If loading failure, goes to abnormality processing;
Step 204, GetWebAppFactory methods are obtained using GetProcAddress functions;
Wherein, the GetWebAppFactory methods are factory method;
Step 205, GetWebAppFactory methods are called to create factory's object;
Factory's object of establishment is WebAppFactory;
Step 206, the CreateWebAppTab methods of factory's object are called to create a Shipping Options Page object;
Wherein, the Shipping Options Page object is WebAppTabWrapper;
Step 207, a WebAppCreateParams object, and the url of populated target and for accommodating page are constructed The window handle in face, then the Create methods by the use of this object as parameter call Shipping Options Page object, notify webkit kernels Create the page;
Wherein, the WebAppCreateParams objects are parameter object;
Webkit kernels create a new page window according to the url and window handle of target, and complete the wash with watercolours of the page Contaminate and show;
Step 208, if the network environment of machine is normal and url is correct, a new page window will become The child window of WebAppCreateParams, and complete rendering and showing work for the page, user can normally with this page Face interacts.
Flow based on Fig. 2, multiple third party softwares can load this interface dll at the same time, complete page browsing, mutually Do not influence, it is mutually invisible.The upgrading of Webkit cores and bug reparations etc., are completed by the upgrading audit function of dll services.Into The operation for not influencing legacy version during row new version update uses, completely invisible to third party software.Third party software leads to Some project for crossing access registration table obtains new service release dll paths, is used after loading.Also, new and old edition can be same When use.
In conclusion interface of the embodiment of the present application for WebKit kernels export WebAppTabWrapper objects, the 3rd After square software obtains WebAppTabWrapper objects, by calling the Create methods of the object, webkit browsers are notified Create a new page.The http request carried out in web page browsing, parses returned data, performs js, establishes dom trees, completes It is all invisible to third party software the specific works such as finally to render, the technology for simplifying third party software uses difficulty.Third party Software and real page access, parsing, rendering module are operated in different processes, that is, realize the access of striding course, between process Isolation protects influence of the third party software from page insecurity well.
Wherein, described " isolating between process " includes two layers of meaning;
First, dll services are mutually isolated with webkit kernels, different processes are operated in respectively;
Second, mutually isolated between third party software, each third party software can independent loads dll services complete Page browsing, does not interfere with each other between each other.
Moreover, the web page access service based on webkit cores be not only restricted to Microsoft's windows operating systems version and Operating system in itself, in non-windows platforms, can also be worked in a manner of similar as above, simplify third party software progress The difficulty of cross-platform version exploitation.
In short, the method for web page browsing is realized using webkit cores present applicant proposes a kind of striding course, can be well Solve the problems, such as the Webbrowser kernel versions backwardness of IE, security is weak, does not support non-Microsoft platform, and directly use Caused by webkit cores the problems such as technical threshold height, scaling difficulty, excessive installation kit.
And it is possible to simplify third party software increased in windows platforms and non-windows platforms using web page browsing it is soft The development difficulty of part function, is allow any third party software to be serviced using web page access provided by the invention, easily accessed The page, enhancing software users experience.
