Description

A kind of data transmission method based on ADE data set control and device

Technical field

The present invention relates to Internet data transmission technology, in particular in Web environment, when using ActiveX control as user interface components, the dynamic data of client computer expresses (ADE:ActiveDataExpression) data set control obtains the new client data model of maximum guarantee and standard HTTP (HTTP:HyperTextTransferProtocol) and Web server WebServer transceiving data method and device by performance and the convenience that uses.

Background technology

Any program of all supports Microsoft Microsoft Component Object Model (COM:ComponentObjectModel) all can create ActiveX control.ActiveX control is as assembly or stand-alone program, can generate by all multiple utility programs and re-use in a computer or distributed network, especially support the distributed Component Object Model (DCOM:DistributedComponentObjectModel) of decentralized environment at COM.In fact, from the angle in fact realizing ActiveX control, also can be a kind of dynamic link library (DLL:DynamicLinkLibrary) module, perform in the application program with the COM routine interface being called " container ", utilize the access mode that can re-use control to contribute to shortening the lifting of Develop Application System time and program function and quality.As, the Window95/N application development instruments such as PowerBuilder and MicrosoftAccess are exactly the benefit that application ActiveX control has, VisualBasic and C++ is widely used in the establishment of object type extension component (OCX:ObjectLinkingandEmbeddingControleXtension) or ActiveX control.

ActiveX control is Microsoft for the general designation of a series of strategic object-oriented program technology and instrument, and its major technique is COM.COM is as developing the infrastructure with support program component object, its target is supported in Common Object Request Broker Architecture, or the horizontal functional of the upper definition of CORBA (CORBA:CommonObjectRequestBrokerArchitecture).Having in catalogue and other network supported, COM becomes DCOM.DCOM be one can independently in the program that any part of ActiveX control network is fully run.ActiveX control is Microsoft is a kind of technology that the Java technology of contending with Sun Microsystems (China) Co., Ltd SunMicrosystems proposes, and can say that ActiveX control and application program JavaApplet are in par.The computer being provided with Windows operating system can find the file much adding .ocx after the extension name of file, i.e. OCX.Object connects the program technic proposed as Microsoft with embedding (OLE:ObjectLinkingandEmbedding), can support as compound documents such as WindowDesktop, provide the service that process user can watch compound document on picture, (namely COM then provides interface negotiation, life cycle management, judge that approximately when object is got rid of from system), licence, Event Service (namely, as event result in other object, an object is distributed to service) etc. infrastructure service.But nowadays Microsoft is that component object uses ActiveX assembly to replace OCX.One of major advantage of ActiveX control can be re-used by most of application program exactly.ActiveX control can utilize different language or developing instrument exploitation, comprising: C++, VisualBasic, or PowerBuilder, or some wscript.exes, as VBScript.At present, ActiveX control can only run on Windows95 or NT and Macintosh, but Microsoft prepares also can support ActiveX control on UNIX.

Fig. 4 is the ADE data set assembly of the transfer of data based on ADE data set control that the embodiment of the present invention provides and the composition schematic diagram of periphery thereof, as shown in Figure 4, client computer for comprising with the ADE data set assembly of Web server transceiving data and the composition of periphery thereof: by the client computer (100) of all kinds Web browser request service used according to the requirement of client; The HTML generated according to the requirement signal exported by described client computer (100) is sent to the Web server (200) of client computer (100); The built legacy system Legacysystem (300) of the middleware information (e.g., Tuxedo, Entera etc.) implemented by the driving of Web server (200) is provided.

Client computer (100) comprising: the DHTML portion (130) implementing new HTMLTag, option, CSS and programming according to the client requirements being input to client computer (100); This result to Web server (200) request HTTP, and is sent to the ADE data set assembly (140) of data storage area by the Web browser used by the client requirements transmitted by DHTML portion (130) after receiving HTTP response-service routine operation result from Web server (200).Wherein, (namely HTTP receives and dispatches file on Web, text, graphic image, Sound, Video and other multimedia file) agreement used, it is an application protocol about transmission control protocol/Internet Protocol (TCP/IP:TransmissionControlProtocol/InternetProtocol), a part for HTTP key concept refers to that it all can have the reference link corresponding to other file with All Files, select this link, then other content is also added the concept formation of the mode of transmission.In other words, all Web servers (200) all have HTTP finger daemon Daemon, and this program segment first waits for HTTP request, can process once receive request to it.In addition, the Web browser of HTTP angle is a client to Web server (200) delivery request, user input URL or click on hypertext reference and demand file time, the HTTP of Web browser transmission requires to write IP address, then this HTTP requirement is received by the HTTPDeamon on given server, if desired, after necessary operation then processes, searched demand file is sent.

ADE data set assembly (140) comprising: the data storage area (1409) storing data; Transmit the object model generating unit (1411) of the picture data corresponding to HTTP request information to client computer (100) generate data object model in the data exported by data storage area (1409) after; The URL analysis portion (1401) that the resource address transmitted the DHTML portion (130) by client computer (100) is analyzed; Receive the data transmitted by URL analysis portion (1401), and ask the HTTP request portion (1403) of HTTP to Web server (200); The data reception portion (1405) of HTTP response-service routine operation result is received from Web server (200); After analyzing the information transmitted by data reception portion (1405), institute's analytical information is converted to the memory organization of data set DateSet form, and then send the data set converter section (1407) of data storage area (1409) to.Wherein, for identifying the domain name of certain computer on URL and the Internet, and the pathname of Display control computer document location level, being on the internet can the generalized expression of access resources address, be the one of Uniform Resource Identifier (URI:UniformResourceIdentifier).Comprise: the protocol name needed for access resources; Identify the domain name needed for certain computer on the internet; And the pathname etc. of computer documents position is expressed with stratification.Resource form can be different because of the difference of internet application, if that is use agreement and the HTTP of World Wide Web (WWW), then the different files that HTML page, image file, CGI (CGI:CommonGatewayInterface) or JavaApple supervisor and other HTTP support all can become resource.Such as, http://www.metro.seoul.kr/kor, the Web page being called the computer of " www.metro.seoul.kr " can be read with HTTP application program and Web browser, "/kor " refers to the catalogue in this computer, if the not written document name in its lower end, then can show the base page (general base page is index.html) of this catalogue.HTTPURL can refer to any Web page, comprises webpage, even can describe a small documents, and namely http://www.terms.co.kr/dgkim.gif can show the photograph image of Terms operator to user.Or, the URL form of message board CGI supervisor, i.e. http://www.terms.co.kr/bbs/bbs.cgi? db=bbs, and the URL utilizing file transfer protocol (FTP) (FTP:FileTransferProtocol) to download certain file is expressed as ftp: //www.somecompany.com/whitepapers/widgets.ps.

User requires to pass to application program CGI by Web server (200), and its result is returned to the standard method of user, is a part for the http protocol of Web.Namely, user's clickable hyperlinks or input Web site address and after asking Web page, Web server can send requested Web page, when user sends the Web page form of contents, need to be processed it by common applications, Web server passes to applet this format information, and applet can deal with data send confirmation as required, and between Web server and application program, the method for transceiving data or agreement are then called as CGI.If create Web site time for certain control and need use cgi script time, this cgi script title is described in the URL of html file, when intending creating list, this URL can be described to a part of FORMSTag, as, using <FORMMETHOD=POSTACTION=http: //www.mybiz.com/cgi-local/formprog.pl> is as the result of this Tag, server in mybiz.com is in order to store the data be transfused to, control is given to the cgi script being called " formprog.pl ", and (.pl here refers to the program created to return confirmation, but CGI also can create with other Languages).CGI is to provide the application program come from client transmission, then passes to a penetrating method of client data, can be sure of from the angle of the research staff of editing application program, and no matter which kind of utilization system Web server uses, and is program operation all the time.CGI is after being delivered to application program to user's request from Web server, then returns to the simple and the most basic method of information.Because interface is consistent, research staff can by different language editor CGI application program, and cgi script can use the most general language on editor, comprising: C, C++, Java, Perl etc.On the other hand, the counte-rplan as GCI program can propose the Active Server Pages (ASP:ActiveServerPage) of Microsoft, as a kind of script that Web page is embedded in, realize running before Web page is sent out on Web server.

The server page (JSP:JavaServerPages) is the technology using Servlet to control perhaps model in Web page, and the JSP technology that Java developer SunMicrosystems proposes is exactly Sevlet application programming interface (API:ApplicationProgrammingInterface).JSP can be equal to the ASP technology of Microsoft, JSP calls the java applet intending being run by Web server, ASP is then before the page is sent in user, make plan by script interpreter ScriptInterpreter (as, VBScript or JScript) script explained also comprises wherein, and the file adding .JSP after file extension refers to the HTML page arriving JavaSevlet link.Wherein, ASP refers to that the HTML page containing more than one script (little plug-in) processes before being sent to user on microsoft web server, and ASP is comparatively similar to as creation of web is supplied to user and perform synchronous serial interface (SSI:SynchronousSerialInterface) or the CGI application program of all relative programs on Web server.The Web page script of server is after requiring to be connected to data storage area according to user, and based on this result, before being delivered to requirements side, creation of web or becomed privileged processes moment.Although the feature that ASP only has Microsoft Internet Information Service (IIS:InternetInformationServer) to have, but due to the common HTML page that server side script creates, nearly all browser all can normally use, therefore, file extension changes into " .asp " create the script comprising VBScript or Jscript in html file after by ASP file.As long as selectively leeway, the general ASP of recommendation server side of Microsoft but not the script of client-side.Because server side script can make HTML be shown more easily, and if use the script (such as, java script) of client-side, then may time of browser longer, cannot run according to the script of client-side.Sevlet is the small routine run on Web server, is at the small routine being passed to other file together with Web page, is the new term created in the environment of JavaApplet.Can simple computing service be run for user or usually being run in client by the JavaApplet write of the services such as picture is set based on the reaction of user, but according to the input of user, the all programs be connected with data storage area are then necessary to run in the server, general these are all use CGI to realize, if but utilize the Java Virtual Machine that runs in Web server and available Java language to realize those programs.The advantage of the JavaSevlet in Web server can run quickly than GCI application program, Sevlet all generates different treatment progress for the request of each user, but with thread dispatching in a finger daemon, the Overhead to each schemes call is less for expression system, substitute the request that the URL of CGI application name is called in the result of JavaSevlet and Web page and can call URL, its form is http:// www.terms.co.kr:8080/servlet/gotoUrl? http://www.someplace.co.kr, URL inner port numbering " 8080 " refers to that this request is directly passed to Web server itself, and several complementary module is that all JavaSevlet can be run on the IIS of NetscapeEnterprise or Microsoft and Apache Server.

Fig. 5 is the flow chart of the ADE data set assembly operating of the transfer of data based on ADE data set control that the embodiment of the present invention provides, as shown in Figure 5, as follows with the carrying out practically step of the ADE data set assembly of the client computer of Web server transceiving data:

Step S501: the URL request HTTP of the service object that designated user is specified.HTTP request portion (1403) is sent to after the URL of the information specified services object that the DHTML portion (130) by client computer (100) sends by the URL analysis portion (1401) of client computer (100).Wherein, the title of specified services object and service object will be returned to data set catalogue.

Step S502: call by the service object of CGI or JavaJSP/ASP or Servlet from data source query data.Data set component property in HTTP request portion (1403) use client HTML page and method, will by the service object of CGI or JavaJSP/ASP on Web server (200) or Servlet from data source query data, and http protocol be used to call legacy system (300).Wherein, data set assembly is the assembly for client computer keeping and management data.

Step S503: result data is processed into transmission form.The HTTP request of legacy system (300) decryption collection, and by after the service object's model load operating on Web server (200), result data is processed into transmission form DataBuffer.Wherein, the version of data Buffer is as shown in the table.

Wherein, overall Size represents all data specifications that overall specification OxFF is later; ' E' represents that Errorinfo field starts, specification is 1; ErrorSize represents the data specification of ErrorCode+ErrorMessage; DatatableCount represents the tables of data quantity comprised in data Buffer; Type represents that the processing mode of tables of data is G=ALLRow, B=BLOB, S, F, X=FirstRow; Size represents the specification of tables of data.

Step S504: be sent to data reception portion.Respond service by HTTP and data are sent to data reception portion (1405).

Step S505: transmit data to data set converter section after extracting real data.Data reception portion (1405) analysis receives the effectiveness of information of data, extracts real data, extracted real data is sent to data set converter section (1407) to after data analysis.

Step S506: recordset object is sent to data storage area.The result data form that extracted data return with the service object's model on Web server (200) is generated RecordSet object in data set component internal by data set converter section (1407), and generated recordset object is sent to data storage area (1409).
