Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Fig. 1 shows the interruption restoration methods process flow diagram of described according to an embodiment of the invention browser control part, and as shown in Figure 1, described method comprises step:
S100: the process intercepting and capturing the page process creation moving object of browser, create agent object and replace the actual moving object that will create, described agent object runs in page process.
Wherein, described moving object is exactly real browser control part, such as real ActiveX object, i.e. ActiveX control; Described agent object can be the browser control part of simulation, and the ActiveX control of such as simulating, described agent object runs in page process.
Concrete example illustrates that the present invention is as follows:
When having ActiveX control in webpage, when browser creates ActiveX control, registration table can be inquired about according to control CLSID or ProgID, wherein can obtain CLSID by CLSIDFromProgID, check whether system has installed corresponding control thus, if install, can constructive process be continued.Browser obtains the IUnknown pointer of corresponding control by calling CoGetClassObject, then carry out mutual operation by standard interface.CoGetClassObject implementation is, registry query ActiveX path is gone to by CLSID, after obtaining ActiveX path, call LoadLibrary and load ActiveX control, call its derivative function DllGetClassObject and obtain class factory pointer (IClassFactory), the CreateInstance method then calling IClassFactory obtains IUnknown pointer corresponding to ActiveX control.
When loading ActiveX control, interception CoGetClassObject, create an ActiveX control agent object, this ActiveX control agent object comprises a series of interface, a lot of standard interfaces that such as IUnknown pointer will call, such as IOleObject, IViewObject etc.Then, when calling the CreateInstance of IClassFactory, created ActiveX control agent object is returned to the IUnknown pointer of ActiveX control.
S200: in the detached process independent of browser page process, create the described actual moving object that will create, described moving object is run in detached process.
Still concrete example illustrates that the present invention is as follows: when the page activates described ActiveX control, extracts the relevant informations such as the attribute of this control, URL, size, then creates a detached process.Specifically, create a file (document), insert an object wherein, this detached process calls CoGetClassObject, tackle this CoGetClassObject, then create another ActiveX control moving object, this ActiveX control moving object comprises a series of interface, a lot of standard interfaces that such as IUnknown pointer will call, such as IOleObject, IViewObject etc.Then, when calling the CreateInstance of IClassFactory, this created another ActiveX control moving object is returned to the IUnknown pointer of the ActiveX control of detached process.
S300: by communicating with detached process and/or its moving object, agent object judges whether moving object interrupts, if so, agent object sends active information to detached process, re-creates moving object in detached process, process ends; Otherwise, direct process ends.
Concrete example illustrates that the present invention is as follows: in created two ActiveX control objects, create a window associated with this control object respectively to be used for communicating.Two control object can be carried out for size, focus, refreshing, script and other information alternately specifically.The all requests in above two processes can be tackled according to method of the present invention, realize the information interaction between these two processes by two the ActiveX control objects be pre-created.The concrete computation process of ActiveX control is carried out in detached process thus, thus can not affect the process of former webpage.
Described step S300 comprises further:
S310: agent object judges by communicating with detached process and/or its moving object whether whether stuck the and/or detached process of moving object collapses.Particularly, agent object regularly inquires the running state information of detached process and/or its moving object, and judges whether the whether stuck and/or detached process of moving object collapses according to described running state information.If find following at least one item according to described running state information: the message loop inertia of moving object place thread, the window of moving object is hung up, always hurrying of moving object thread, then judge that moving object is stuck; If find following at least one item according to described running state information: the main window in detached process does not exist, and the window in moving object does not exist, then judge detached process collapse.
Agent object regularly inquires the running state information of detached process and/or its moving object, can realize this supervisory control action specifically by a lot of mode, for example, and can for each moving object binds a message window in the detached process of opening; Make the agent object of page process inquire about this message window termly, whether normally run to monitor this moving object.S320: if moving object is stuck, then agent object stops with the communication of described moving object and sends active information to detached process, in detached process, re-create moving object.
S330: if detached process collapse, then create new detached process, agent object sends active information to detached process, re-creates moving object in detached process.
By the execution of said method step, can the interruption of identification activity object in time, and have no progeny in moving object it is reactivated in time, shorten the response time.
In addition, step can also be comprised after described step S200:
P1: agent object regularly inquires the operation information of moving object, and preserve described operation information.
Correspondingly, in described step S300, described agent object sends active information to detached process, in detached process, re-create moving object, is further:
Agent object sends described active information and described operation information to detached process;
According to described active information, in detached process, re-create moving object;
According to described operation information, obtain the interruption position of former moving object, the new moving object created of order continues to run at described interruption position place.
Wherein, described active information mainly: the information such as attribute, URL, position, size of moving object; Described operation information is the operation progress msg of moving object.By adopting described step P1, and described step S300 being changed accordingly, can ensure that moving object can start to rerun at interruption position place, restarting completely compared to existing technology, obviously further increase response efficiency.
Can also select whether to reactivate the moving object of having interrupted to improve the interactive performance with user by user in described step S300, particularly, it may further include:
By communicating with detached process, described agent object judges whether moving object interrupts, if so, prompting User Activity object interrupts;
Receive the reactivation instruction of user;
Agent object sends active information to detached process, in detached process, re-create moving object.
Can also step be comprised after described step S300:
S400: agent object, by communicating with detached process, calls moving object, and/or, agent object by communicating with detached process, by active object calls.
A usual browser often can open a lot of the pages to browse different webpages, see Fig. 2, described method can also be applied to the situation of multi-page, now can run multiple moving object by the corresponding multiple page of multithreading, particularly, described method step is as follows:
S100 ': page process is each page creation page thread, intercepts and captures the process of page thread activity of constructing object, and create agent object and replace the actual moving object that will create, described agent object runs in page thread.
S200 ': detached process is the object thread of each page creation one independent of page thread, in described object thread, create the described actual moving object that will create, described moving object is run in object thread.In this step, detached process creates main thread, and main thread is the object thread of each page creation one independent of page thread, and described main thread is for safeguarding global configuration.
Further, in this step, during detached process activity of constructing object, agent object as communication identifier, sends the communication handle of page process or page thread and agent object mark to detached process or object thread; After detached process activity of constructing object, moving object as communication identifier, sends the communication handle of detached process or object thread and moving object mark to agent object.
S300 ': with object thread communication, agent object is by judging whether moving object interrupts, if so, agent object sends active information to object thread, re-creates moving object in object thread.
Described moving object comprises ActiveX object, for ActiveX object, then ActiveX object runs in object thread, when ActiveX object goes wrong, such as, when ActiveX object is absorbed in endless loop, can, to the object thread execution pending operation running described ActiveX object, described object thread temporarily can not be run; Or limiting operation is reduced to the object thread execution running described ActiveX object; Or to running the object thread executive termination operation of described ActiveX object, the object thread described in termination.
In such as, implementation in the method described in the application, for ActiveX control in IE browser, the ActiveX class factory of simulation can be created, replace real ActiveX class factory, in page process or page thread mock standard mode, create agent object, such as, the model with reference to following:
ActiveX proxy class can being created, for completing the total interface of true ActiveX class, and forwarding the operation such as initialization, transmission data, delivery status and execution readjustment to ActiveX object, such as, the model with reference to following:
