Embodiment

Below in conjunction with embodiment, the invention will be further described, and embodiments of the present invention include but not limited to the following example.

Embodiment

For the ability that solves the webkit dynamic load local library existed in prior art poor, and the ability of expansion oneself application is poor in webkit, the problem that can't meet consumers' demand, the invention discloses a kind of local extended method of the storage resources service based on the webkit kernel, because prior art peripheral user is mainly undertaken alternately by http protocol and gateway, by gateway, undertaken after protocol conversion again and the storage inside system interaction, the storage inside system is carried out the corresponding service request of replying again afterwards according to request and is sent to gateway, the reply of client requests externally is provided by gateway again, thereby, the present invention has carried out research and development to part mutual between front end and gateway and has improved, be added in the webkit kernel and realize the expansion to browser function by the API by cloud storage system, it mainly comprises the following steps:

Adopt the mode of binding, be that the .idl file compiling that webkit provides according to the user generates JSXXX.cpp, JSXXX.h, WebKitDOMXXX.cpp, WebKitDOMXXX.h and WebKitDOMXXXPrivate.h file, wherein, the JSXXX.cpp of generation and JSXXX.h are associated with original JavascriptCore in server;

To show under be put into/Source/webCore/page of relevant extended operation catalogue with the page;

Write interface function, interface function is programmed in the .cpp file of user's needs; Write the idl file that comprises IDL attribute, interface attributes and parameter etc., wherein, the IDL interface specification is with reference to WEB IDL standard; DOMWindow.h, DOMWindow.cpp and DOMWindow.idl are carried out to corresponding modify;

Revise the compilation process of makefile.am file, in the GNUmakefile.list.am under Source/WebCore, add corresponding h, cpp and idl file and JSXXX.h and JSXXX.cpp; Add corresponding WebKitDOMXXX.h, WebkitDOMXXX.cpp in the GNUmakefile.am under Source/WebCore/bindings/gobject.

Take DOMWindow and JSDOMWindow as example, and wherein, JSDOMWindow only provides the semanteme of interface, and DOMWindow provides its concrete realization.Finally realize its function to three grades of mapping relations of C++ by HTML again to JS, call the javascript interface in HTML, and between javascript and C++, be the relation of interface and realization, interface adopts the javascript mode to be defined and the realization of interface adopts the mode of C++.Wherein with the mutual part of background service system, by the C++ object, encapsulated, by under put into/WebCore/page of packaged object catalogue; Simultaneously, write idl file, the calling interface of JS be resolved and be converted into to system can in order to contact with high-level interface according to idl file.

According to above step, just can realize the local function expansion of the corresponding interface.

In the present invention, API has mainly simulated the message format of http protocol, and http protocol is encapsulated, and by sending the HTTP message, background server is filed a request to the function that realizes that the user is required.In order to be achieved, the mode that need load the html page in application layer by webkit is called the application layer api interface.The interface lexical or textual analysis is as table 1:

Table 1

In the present invention, each message request must comprise the mutual complete message form of communication, and the state of this message is irrelevant with the state of message before.REST has described the interacted system of a framework pattern, and REST constraint condition is during as an overall applicability, will generate one simple, can expand, effective, safe and reliable framework.

The service process of a whole set of cloud storage system is as follows: the user sends request by calling registration interface to backstage, and after succeeding in registration, the user logs among system by account, carries out own needed operation.File is pressed the sheet access, and storing process is divided into data storage and metadata store, and upload file metadata after all bursts of whole file are all uploaded successfully, download as its inverse process; Directory operation is the operation for its metadata information.Wherein file operation is divided into: upload, download, delete and inquire about; Directory operation is divided into: create, delete, obtain catalogue and obtain directory states.

The mode that application layer user loads from browser by the html file by given is called application layer javascript API, and then the realization of calling bottom C++, and the background server transmission order to us, require background server that service is provided.For this reason, the function services design interface that we can be in advance can provide according to user's demand and our background server.Our interactive interfacing partly relates generally to be and gateway between mutual, therefore we need to simulate encapsulation and the parsing to http protocol, the demand encapsulation according to us that is us by the HTTP message protocol of basic principle, web server by the gateway end first carries out the parsing of agreement request, and the corresponding status request field of having resolved is sent to gateway, carry out different operations by gateway according to different field lexical or textual analysis again, Recovery Process is its inverse process, finally replys message and is sent to front end subscriber by web server.

The interface of upload file sheet of take is example:

The interface designed is write under WebCore/page in corresponding packaged file to the absolute path that parameter is the file that need to upload.

Upload procedure is divided into uploading data and metadata information, and file is carried out to burst according to certain size, according to the http protocol form designed, by data upload; Completing after whole file data uploads successfully, after the form encapsulation by the metadata information of file according to design, uploaded, upload and successfully indicate that whole file uploads successfully.

The web server that the HTTP message of uploading can first be delivered to the gateway end carries out protocol analysis, and will resolve accordingly field and be sent to gateway as unique cryptographic hash of user's authorization information, file fragmentation information, file sheet etc., carry out corresponding protocol conversion by gateway according to different fields, the agreement request of letter is sent to background service system, by service system, completes corresponding operation.

Corresponding interface is added in corresponding .idl file according to WEB IDL format specification, in order to generate corresponding JS calling interface, contact with Applied layer interface.

Write corresponding calling interface with HTML, in three grades of invoking upon mapping modes of interface that we were mentioned, carry out the work of calling of interface.

The working specification of all the other interfaces is similar, our packaged example all is based on the operational instances of webpage, former capital will be positioned over it under page catalogue, and create their the routine example of list in the DOMWindow object, in other words, they are to place and exist in the mode of global object, due to each parameter in the present invention write and the behavior of calling is proven technique very in industry, thereby more do not speak more bright at this.

According to above-described embodiment, just can realize well the present invention.
