For solving above-mentioned at least one technical matters, the embodiment of the invention provides a kind of plug-in unit player method, be used for to realize the independent operation of plug-in unit and page process, can not affect the stability of another one when guaranteeing one of any generation problem therein.Fig. 1 shows the according to an embodiment of the invention processing flow chart of plug-in unit player method.Referring to Fig. 1, the plug-in unit player method comprises that step S102 is to step S106.Being described as follows of each step.
Step S102, when the page process of browser loads and activates the first plug-in unit, creates the detached process different from page process, loading and activate the second plug-in unit in detached process, wherein, the second plug-in unit copies the information of the first plug-in unit.
Step S104, in detached process, the information of the second plug-in unit is calculated, obtain result of calculation.
Step S106, in broadcast window, the second plug-in unit is drawn broadcast according to result of calculation.
In embodiments of the present invention, in the page process of browser, load and activate the first plug-in unit, but the first plug-in unit is not drawn broadcast, but create a detached process different from page process, and in detached process, load and activate the second plug-in unit, utilize the second plug-in unit to realize copying the first plugin information.Because the information of the first plug-in unit and the second plug-in unit is consistent, therefore, it is consistent calculating with the information of the first plug-in unit is calculated obtained result of calculation to the information of the second plug-in unit, and it also should be consistent then in broadcast window the second plug-in unit being drawn the content that broadcast plays according to result of calculation.But, because the second plug-in unit is arranged in the detached process, share a process with detached process, from page process applicable two different processes respectively, therefore, the operation of the operation of the second plug-in unit and page process is independently, and the stability that problem can not affect the opposing party occurs a side.If the second plug-in unit occurs stuck or collapse after, can not cause whole webpage to withdraw from, can improve the stability of page operation, in like manner, after page process occurs stuck or collapses, can not cause the second plug-in unit in the page to withdraw from yet, improve the stability of plug-in component operation.This shows, the plug-in unit player method that the embodiment of the invention provides can under the prerequisite that does not affect result of broadcast, improve the stability of browser execution.
Further, owing to the first plug-in unit is not really carried out, and the second plug-in unit is real executive agent, therefore, can claim that the first plug-in unit is agent object, and the second plug-in unit is moving object.The embodiment of the invention is by moving agent object in page process, and in detached process, move moving object, so that real browser plug-in, for example real ActiveX plug-in unit separates with page process, thereby make the browser plug-in Shi Buhui that goes wrong affect the browser process of embedding browser plug-in unit, be that the browser plug-in Shi Buhui that goes wrong affects page process, thereby improved the stability of browser.Simultaneously, when browser plug-in appearance virus waits the problem of security, because browser plug-in separates with page process, can not affect the operation of page process, thereby improve the security of browser yet.
In addition, when browser plug-in goes wrong, can hang up, reduce the operations such as authority or termination to the object thread execution of running browser plug-in unit, thereby so that detached process can be done directed distribution to system resources such as the EMS memory occupation of browser plug-in and CPU take, realize better resource distribution way of recycling, more rational dispatching resource, the termination process also can allow the resource recovery more thorough so that process withdraws from.
Need to prove, in embodiments of the present invention, claim that the first plug-in unit is agent object, and the second plug-in unit is moving object, has embodied the first plug-in unit different with the initiative of the second plug-in unit.When implementing, the plug-in unit player method that the embodiment of the invention provides can be realized two-way communication, page process and detached process are not what fix, follow-up implementation might occur the plug-in unit in the detached process is separated to situation about carrying out in the page process, at this moment, agent object and moving object role exchange, its concrete processing procedure is similar.
Mention that in step S102 the second plug-in unit need to copy the information of the first plug-in unit, for guaranteeing the consistent of result of broadcast.Concrete, this example provides a kind of preferred copy mode.At first, be that the first plug-in unit generates the first control object in page process.Secondly, be that the second plug-in unit generates the second control object in detached process.Then, utilize the second control object and the first control object to carry out interactive communication, obtain the information of the first plug-in unit, the information that recycles the first plug-in unit that the second control object will obtain is sent to the second plug-in unit.
Owing to needing to operate between plug-in unit and self the corresponding control object, therefore, needing to have the interface of information interaction between the two.In the embodiment of the invention, arrange between plug-in unit and control object and carry out mutual operation by pointer, wherein, this pointer can call a plurality of standard interfaces.Concrete, carry out mutual operation by pointer between the first plug-in unit and the first control object, carry out mutual operation by pointer of the same type between the second plug-in unit and the second control object.Preferably, this pointer can be the IUnknown pointer, and the IUnknown pointer will call a lot of standard interfaces, such as IOleObject, IViewObject etc.
When utilizing the second control object and the first control object to carry out interactive communication, for convenient communication, can in page process, create the first window related with the first control object, then in detached process, create the Second Window related with the second control object.Subsequently, utilize first window and the Second Window set up to carry out interactive communication.
In the implementation process, the information of interactive communication can be that plug-in unit is play related any information, for example, and the size of plug-in unit, the focus of the thread in the page process, the refresh operation of the thread of page process, execution of script etc.Specifying information herein only is that conduct exemplifies, and does not cause restriction for information itself, and communication can also relate to other information that plug-in unit is play.
Step S106 mentions, in broadcast window the second plug-in unit is drawn broadcast according to result of calculation.That is, when the second plug-in unit is play, can be divided into two kinds of situations, a kind of is the broadcast window that does not have the first plug-in unit in the page process, and another kind is the broadcast window that there is the first plug-in unit in page process.Now respectively both are specifically described.
The first situation when there is not the broadcast window of the first plug-in unit in page process, is utilized the newly-built broadcast window of detached process.At this moment, because broadcast window is that detached process is newly-built, therefore there is no with original page process and contact.One or more timers are set in detached process, and timing acquisition is to the result of calculation of the second plug-in unit, and then in newly-built broadcast window the second plug-in unit drawn broadcast according to result of calculation and get final product.
The second situation, at this moment identical with the first situation when having the former broadcast window of the first plug-in unit in the page process, utilize equally the newly-built broadcast window of detached process.But, owing to there being former broadcast window, therefore, need between newly-built broadcast window and former broadcast window, setting up and contact.Concrete, newly-built broadcast window is set to the parent window of former broadcast window, then, in newly-built broadcast window the second plug-in unit is drawn broadcast according to result of calculation.
Newly-built broadcast window can move or convergent-divergent at browser, thereby realizes mobility, extensibility of broadcast window etc.Be presented on the broadcast window place of former page process if wish broadcast window, the window's position that then only needs newly-built broadcast window to be arranged on former page process gets final product.
Further, in implementation process, if the request that broadcast window is obtained in the initiation of page process, detached process informs that page process is without broadcast window.Page process can not be known the existence of broadcast window, then can not control broadcast window, thereby realize separating of plug-in unit and page process, improves the stability of browser.
In above-mentioned any one preferred embodiment, the first plug-in unit and/or the second plug-in unit are the ActiveX plug-in unit.
The flash plug-in unit is a kind of ActiveX plug-in unit commonly used, now operates to example with the flash plug-in unit in page process, and the plug-in unit player method that the embodiment of the invention is provided is specifically described.
Fig. 2 shows the schematic diagram that communicates between page process and detached process according to an embodiment of the invention.
In page process one side,
In the situation that flash is arranged in the webpage, when browser creates ActiveX plug-in unit (being the first plug-in unit that preamble is mentioned), can obtain CLSID by CLSIDFromProgID according to plug-in unit CLSID or ProgID() the inquiry registration table, whether the system of checking has installed corresponding plug-in unit, then can continue constructive process if install.
Browser obtains the IUnknown pointer of corresponding plug-in unit by calling CoGetClassObject, then carry out mutual operation by standard interface.The CoGetClassObject implementation is, go to registry query ActiveX path by CLSID, after obtaining the ActiveX path, call LoadLibrary and load the ActiveX plug-in unit, call its derivative function DllGetClassObject and obtain class factory's pointer (IClassFactory), the CreateInstance method of then calling IClassFactory obtains IUnknown pointer corresponding to ActiveX plug-in unit.
Need to prove herein, when loading the ActiveX plug-in unit, the Hook(interception) CoGetClassObject, create an ActiveX control object (i.e. first control object corresponding with the first plug-in unit), this ActiveX control object comprises a series of interfaces, IUnknown pointer a lot of standard interfaces that will call for example, such as IOleObject, IViewObject etc.Then when calling the CreateInstance of IClassFactory, the ActiveX control object that creates is returned to the IUnknown pointer of ActiveX plug-in unit.
In detached process one side,
When page process activates this ActiveX plug-in unit, extract the relevant informations such as attribute, URL, size of this control, then create a detached process, and in detached process, load ActiveX plug-in unit (i.e. the second plug-in unit).
Specifically, create a document, insert therein an object object, this detached process is called CoGetClassObject, this CoGetClassObject of Hook creates another ActiveX control object (i.e. second control object corresponding with the second plug-in unit) again, and this ActiveX control object comprises a series of interfaces, IUnknown pointer a lot of standard interfaces that will call for example, such as IOleObject, IViewObject etc.Then when calling the CreateInstance of IClassFactory, this another ActiveX control object that creates is returned to the IUnknown pointer of the ActiveX plug-in unit of detached process.
Between page process and detached process,
Creating respectively a window related with each control object in two ActiveX control objects that create communicates being used for.Specifically two control object can be for size, focus, refresh, script and other information carries out alternately.
All requests that the method that provides according to the present embodiment can be tackled page process and detached process direct interaction.If page process and detached process need to communicate, then realize information interaction between these two processes by two ActiveX control objects that are pre-created.Because the independence of detached process and page process, therefore, the concrete computation process of flash plug-in unit is carried out in detached process, thereby can not affect former page process.
Further, in the procedure for displaying of flash, can a newly-built broadcast window, then the result who calculates in the detached process is drawn in newly-built broadcast window, following two kinds of situations were described as follows in existing minute.
The first, the flash plug-in unit in the page process are the situations without the flash plug-in unit of broadcast window.
The schematic diagram that flash plug-in unit when Fig. 3 shows flash plug-in unit in the page process according to an embodiment of the invention without broadcast window is play.In Fig. 3, when the result who calculates in the detached process is drawn in newly-built broadcast window, a timer is arranged in detached process, according to predetermined time the interval call IViewObject interface Draw method and obtain draw data, be plotted in the flash broadcast window of new establishment with the data that will calculate.
When the user wishes to show, newly-built broadcast window can be arranged on the flash broadcast window position of the former page, but this window is removable, convergent-divergent etc., to satisfy user's demand in the flash of former page window.
The second, the flash plug-in unit in the page process are the situations that the flash plug-in unit of broadcast window is arranged.
The schematic diagram that flash plug-in unit when Fig. 4 shows flash plug-in unit in the page process according to an embodiment of the invention broadcast window is arranged is play.The result who calculates in the detached process is drawn in newly-built broadcast window, and newly-built broadcast window is set to the parent window of flash broadcast window in the former page.
Particularly, by calling the IOleWindow interface GetWindow method of flash object, obtain its corresponding window, then the parent window of flash broadcast window is set by SetParent.
When the user wishes to show, newly-built broadcast window can be arranged on the flash broadcast window position of the former page, but this window is removable, convergent-divergent etc., to satisfy user's demand in the flash of former page window.
Further, in former page process, on the opportunity of obtaining window, detached process is returned sky.Specifically, when page process scroll through pages, can call the IOleWindow interface GetWindow method of flash object and judge whether the flash object has window, if window is arranged then by sending WM_MOVE message moving window, returns N ULL by GetWindow and forbid that page process moves the flash window.
In summary, the present embodiment provide a kind of in browser the method for player plug-in, realized really peeling off of webpage and plug-in unit, and then just solved the pin function that embeds complete and plug-in unit and the interactional problem of the page.
