Description

Method, browser and server for loading plug-ins

Technical field

The present invention relates to the field of plug-in loading, and more particularly to a method of loading a plug-in, a browser, a server, a computer program, and a computer readable medium.

Background technique

ActiveX is an open, integrated platform that provides developers, users and Web producers with a quick and easy way to create program integration and content on the Internet and intranet. With ActiveX, you can easily and easily insert multimedia effects, interactive objects, and complex programs into your web pages to create high-quality multimedia CD-ROMs with comparable user experiences. ActiveX-based ActiveX plugins are also becoming more widely used. ActiveX plug-in technology is an internationally popular Windows-based software technology. Many softwares are developed in this way, such as Flash animation playback plug-ins, Microsoft Media Player plug-ins, Adobe PDF reading plug-ins, and so on.

The ActiveX plugin is called an OLE plugin or an OCX plugin. It is a software component or object that can be inserted into a web page or other application. For example, when a user browses to a particular web page, the browser prompts the user to download and install the ActiveX plugin.

In the prior art, although the browser side generally has some basic functions of the ActiveX plug-in, many web pages also have an ActiveX plug-in, which requires the user to download and install the ActiveX plug-in that comes with the webpage to implement a certain function of the webpage. . For example, the browser has a built-in plug-in Qvod plug-in that can support the playback of some webpage elements, but the webpage stipulates that the Baidu audio-visual plug-in is used to play some webpage resources. Therefore, even if the built-in Qvod plugin of the browser supports the playback of the video files in the webpage, Users can only download and install Baidu audio and video plug-ins for video playback, resulting in waste of resources. And the process of downloading and installing the ActiveX plug-in of the webpage may cause the webpage to block, so that the loading speed of the page embedded with the ActiveX script program is reduced, and even the browser instantaneously loses the response.

Specific embodiment

The invention is further described below in conjunction with the drawings and specific embodiments.

Referring to FIG. 1 , a flow chart of a first embodiment of a method for loading a plug-in according to an embodiment of the present invention is shown. The embodiment may be configured from the browser side, and may specifically include the following steps:

Step 101: When the browser side intercepts the creation requirement of the first plug-in object in the process of loading the webpage, creating a proxy object, and acquiring parameter information of the first plug-in object;

In the embodiment, the first plug-in object may be an ActiveX plug-in specified in a webpage, such as Baidu video and audio, QVOD (fast broadcast), and the like. The browser side intercepts the creation requirement of the first plug-in object in the process of loading the webpage, and specifically, when the hook is hooked to the CoGetClassObject function in the process of loading the webpage on the browser side, the first plug-in object is intercepted. Create a requirement.

Specifically, the ActiveX plugin is a COM (Component Object Model, group) Component object model), in the COM library, there are three API (Application Programming Interface) functions for object creation, which are CoGetClassObject, CoCreateInstance and CoCreateInstanceEx respectively. Usually, the client calls one of them. Complete object creation, and return the object's initialization interface pointer, COM library and class factory (class factory is also an interface or COM object, its responsibility is to create a component object and return a pointer to the client interface, each component must There is a related class factory that also interacts through these three functions.

The CoGetClassObject declaration can be expressed as follows:

STDAPI CoGetClassObject(REFCLSID rclsid,

DWORD dwClsContext,

COSERVERINFO*pServerInfo,

REFIID riid,

LPVOID*ppv);

Among them, rclsid is used to uniquely identify the CLSID (128 bits) of an object. Through rclsid, you can know the object you need to create (you need to use it to create the specified object); dwClsContext is the component category, you can use the predefined value in the CLSCTX enumerator. ; pServerInfo is a pointer to the machine where the instantiated class object is located (if the local machine, the parameter is NULL); riid is the reference interface identifier, used to communicate with the object; ppv is stored as the output parameter to return the class factory Interface pointer.

When the client program calls the COM library function CoCreateInstance to get the class factory interface pointer, CoCreateInstance calls the function CoGetClassObject, uses the parameter CLSID to find the registry in the function CoGetClassObject, finds the path of the COM component DLL and loads it, and calls the function implemented in the DLL. DllGetClassObject, DllGetClassObject function creates a class factory, and returns the class factory interface pointer to CoGetClassObject in reverse order, and creates an object according to the class factory interface pointer. In the embodiment of the present invention, when the page process on the browser side needs to create an object, the CoGetClassObject function performs a hook (hook is a system mechanism provided in Windows to replace the "interrupt" under DOS, and the Chinese translation is " Hook "or" or "hook") to prevent the creation of objects.

In the embodiment of the present invention, it is known that the object needs to be created for hooking to the CoGetClassObject function in the browser side, thereby starting the creation of the proxy object (Prox object), and replacing the object actually created by the CoGetClassObject function with the Prox object. Among them, the Prox object includes a series of interfaces, including many standard interfaces that the IUnknown pointer will call, such as IOleObject, IViewObject, etc., and then call IClassFactory (class factory) When CreateInstance is created, the created proxy object prox is returned to the page process's IUnknown pointer, and the proxy object is created.

In practice, the parameter information of the first plug-in object can be obtained from the page process of the browser side while the plug-in object is created, so as to know the plug-in that needs to be created. In a preferred example of the embodiment of the present invention, the parameter information of the first plug-in object may include an identifier of the first plug-in object and a URL of the first file, where the URL of the first file is according to the first plug-in object. The URL generated by the protocol, which can include the file name, file size, and file hash value. For example, when the first plug-in object is a Baidu Player (BaiduPlayer) plugin, the parameter information can be:

</object>

Among them, object is the unified use of COM components in the HTML language; classid is the call statement to the WEB plugin in the HTML language; clsid is the value of the BaiduPlayer plugin type ID; width/height is the width and height of the plugin displayed in the webpage; Id/name/ is the identifier of the BaiduPlayer plugin; the URL is the play file address (that is, the URL of the first file), and the URL value format is bdhd://file size|file hash value|file name (bdhd is the URL address generated by BaiduPlayer) Protocol); AutoPlay is automatic playback, 0: no automatic playback 1: automatic playback, the default is not automatic playback.

Step 102: Send parameter information of the first plug-in object to a server side.

Step 103: Receive parameter information of the second plug-in object returned by the server, where the parameter information of the second plug-in object is determined by the server side to determine that there is a replaceable second plug-in object according to the parameter information of the first plug-in object. Time extraction

In the embodiment of the present invention, when the page process on the browser side is loaded into the ActiveX plugin in the webpage, it can be replaced with the ActiveX plugin (the second plugin object) built in the browser side, so that the ActiveX plugin built in the browser side is enabled. The ability to take over and open network elements of the file formats supported by the current page, preventing users from downloading and installing ActiveX plugins in web pages.

Specifically, the browser side uploads information such as the identifier of the first plug-in object and the URL of the first file to the server side, and the server side determines whether the plug-in can be performed. Replace the operation. In a specific implementation, various data resource files (including file name, file size, and file hash value) are stored in the data resource library on the server side, and the server side can respectively press each data resource file in the data resource library according to the browser. The protocol of the second plug-in object built in the side generates the URL of each data resource file (ie, the URL of the second file), and generates a mapping relationship between each data resource file and the corresponding URL and stores it in the mapping table. When the server side receives the identifier of the first plug-in object uploaded by the browser side and the URL of the first file, obtaining a file name, a file size, and a file hash value file in the URL of the first file of the first plug-in object. Information, in the mapping table, find a file name, a file size, and a file hash value that are the same as the file name, the file size, and the file hash value in the URL of the first file, and if the search succeeds, it is determined that the second file can be performed. The replacement of the plug-in object and obtaining the URL of the corresponding second file (for example, the URL of the second file corresponding to the play address of Baidu video and audio can be:

Ed2k://|file|Lucky%20Girl%20-%20Just%20My%20Luck%20French%20Dvdrip%20Xvid-Justmyluck-Songo52%20Par%20Idonkey%20Ws.avi|729925632|73CF7916F3ABD182035C82A69CCA29F9|/), the server side will correspond The URL of the second file and the identifier of the second plugin object (the URL of the second file and the parameter information of the second plugin object composing the second plugin object) are returned to the browser side.

In addition, when the server side does not find a file name, a file size, and a file hash value in the URL of the first file in the mapping table, it is determined that the file name, the file size, and the file hash value are not present. The second plug-in object is replaceable, and the prompt information returned by the server side is sent to the browser side, and the browser side releases the intercepted CoGetClassObject function according to the prompt information, thereby creating a first plug-in object, and adopting the first plug-in object and the proxy The object communicates to implement loading of the web page.

Step 104: Create a second plug-in object according to parameter information of the second plug-in object.

Specifically, after the browser side receives the parameter information of the second plug-in object returned by the server side, the parameter information of the second plug-in object is replaced with the parameter information of the first plug-in object in the page process, and the browser side After loading the page process, after obtaining the class factory interface pointer in the CoGetClassObject function, the creation function in the class factory is called to create a second plug-in object, wherein the second plug-in object is an object that actually implements the plug-in function.

Step 105: Establish an association between the proxy object and the second plug-in object.

In the embodiment of the present invention, a communication window associated with the object may be separately created in the proxy object and the second plug-in object to establish an association between the proxy object and the second plug-in object, so that the proxy object and the second plug-in object The communication can be performed through the communication window, and the proxy object invokes the second plug-in object and/or the first through the communication window of the proxy object and the second plug-in object. The second plugin object invokes the proxy object to implement the functionality that the plugin implements.

Step 106: Configure a script for running the second plug-in object by using the proxy object;

In a specific implementation, the communication between the proxy object and the second plug-in object includes a script execution process between processes, and the script running by the second plug-in object is configured by the proxy object. In a preferred embodiment of the present invention, the parameter information of the first plug-in object may further include a first function function, and the script run by the second plug-in object may include a second function function of the second plug-in object. Step 106 can include the following sub-steps:

Sub-step S21, when the first function is called, the proxy function is used to replace the first function function with a corresponding second function function;

Sub-step S22, using the proxy object to configure a script for running the second plug-in object according to the second function function and the URL of the second file.

Specifically, the proxy object may replace the first function function with a corresponding second function function in the second plug-in object by using a scheduling interface IDispatch interface. In a specific implementation, when the page process on the browser side loads the webpage, when parsing the script in the first plug-in object, the name of the method to be executed in the script is transferred to the IDispatch interface of the proxy object, and the IDispatch interface is scheduled. The interface is used to call a function in a language program that does not support the virtual function table. The IDispatch interface has a GetIDsOfNames function and an Invoke function, wherein the GetIDsOfNames function provides a method for returning its dispatch ID by using the name of the method, and the Invoke function provides a method of utilization. The instruction of the dispatch ID execution method. Since the first plugin object is not actually created, and the second plugin object is the object of the real plugin, the proxy object calls the IDispatch interface of the second plugin object through the communication window, and calls the method provided by the GetIDsOfNames function of the second plugin object, so that The second plug-in object acquires a scheduling ID of the method to be executed, and acquires a corresponding function function (second function function) according to the scheduling ID, and then the second plug-in object returns the scheduling ID and the second function function to the second function function through the communication window a proxy object, the proxy object replacing the second function function with the first function function (for example, the Play function in the first plug-in object, when the Prox object is called, is actually mapped to the corresponding Play function of the second plug-in object, The name may not be play, but the function is completely consistent. Then, the script running by the second plug-in object is configured according to the second function function and the URL of the second file.

Step 107: Perform loading of the webpage according to the script by using the second plug-in object.

Specifically, after the proxy object completes the configuration of the script of the second plug-in object, the script is fed back to the page process, and the page process uses the second plug-in object to execute the Invoke (ID) index. Order, thus executing the method to be executed in the script to complete the loading of the page.

In the embodiment of the present invention, the replacement operation of any ActiveX plug-in in the webpage can be implemented, so that all the data resources in the browser side can find a suitable or unified ActiveX plug-in for loading, without requiring the user. Manual installation greatly improves the efficiency of loading data resources on the web page on the browser side.
