The method of discontinuous transmission comprises: a network server end controls the initialization of a client side, a register component obtains data from a database of a sever, data is transmitted to users by a page control program, and a forcible reset program is set for continuously reading data which is not transmitted completely until all data is transmitted completely.
Description
Technical field
The present invention relates to a kind of data transmission method that is used for the Internet, particularly a kind of dynamic technique of HTML(Hypertext Markup Language) that utilizes continues the method that passes data.
Background technology
The Internet (Internet) is a global Wide Area Network; this network utilisation telephone line or special circuit connect mechanism of global school, NGO and various research unit, and the user can communicate news, transmit Email or file with other people on the network of any one connection.
The method of user's online generally is the computer via one " client (client) " end, utilizes " server (server) " computer contact at a distance on telephone wire or special circuit and the computer network.The server computer is then downloaded (download) script (comprising image, literal or application program etc.) and is given client's computer, examines execution closely for the user.
And in the Internet, the intercommunication of client's computer and server then will be passed through software protocol (softwareprotocols) agreement, file transfer protocol (FTP) (File Transfer Protocol for example, FTP), simple email transfer protocol (Simple Mail Transfer Protocol, SMTP), HTML (Hypertext Markup Language) (Hypertext Transfer Protocol, HTTP) and Gopher etc.HTTP wherein is present the most frequently used World Wide Web (WWW) (World Wide Web, a kind of agreement WWW) of going up.
World wide web (www) is multimedia (multimedia) inquiry system on a kind of network, and this system is main to be to bring into play multimedia transmittability on network, and becomes one main flow on the present the Internet.The World Wide Web (WWW) includes a plurality of servers, we are commonly referred to as " website (sites) ", and the many forms making multimedia files (being commonly referred to as content for script (content)) with HTML(Hypertext Markup Language) of website are downloaded or retrieving information on the computer that can surf the Net for the individual at present.
HTML (Hyper Text Mark Language), HTML is worked up a kind of multimedia of coming, the indicating language of hypertext by European quantum physics laboratory.It is widely used on the World Wide Web (WWW) (www, World Wide Web) of the Internet (Internet) at present.This language utilizes hyperlink (hyperlink) to connect different medium, transmits multimedia ability so possessed on network.A html file is combined by many labels (tag) and script (script), and it is general plain text format text file usually, so we can use general word processor to write it.This has illustrated that also HTML is a kind of cross-platform language.Label then is used for setting up hyperlink, the control code in the middle of its somewhat similar E-TEN Corp Chinese file.Because HTML is an emerging language, so its grammer is still in the evolution that continues.The website that we will browse is if use newer language, and then the user relatively also will use the browser (browser) of supporting new edition HTML.
The up-to-date specification of HTML is 4.0 editions at present, can support dynamic web page, and we are referred to as DHTML.And the D of DHTML represents Dynamic, emphasizes that it is dynamic, promptly is the HTML that can dynamically change again.The html element spare that we can utilize script (script) to come access to define originally but changes its some character arbitrarily, and reaches dynamic effect.Label that DHTML is used and HTML are identical.But support the browser of DHTML, but different with conventional HTML browser program framework.In the conventional HTML browser, if webpage read in finish after, just can not change again.And the DHTML browser is set up an object with each html tag when reading in webpage, thus even webpage all reads to be finished, we still Available scripts (script) change Properties of Objects (as color, position etc.).And browser will show these changes to screen that it is so-called that Here it is " dynamically " at once.
Generally we can watch the program of World Wide Web (WWW) information to be called browser (browser).The browser of computer circle then specially refers to can browse on the internet the program of website, all is at the common browser of PC as MicrosoftInternet Explorer (IE) and Netscape Navigator (NC) etc.The main browser of DHTML has IE4.0, IE5.0 and NC4.5 at present.And according to the difference of browser, the degree of supporting the DHTML label dynamically to change also has difference.
Also can add some software elements in the html file, to promote the ability of HTML access internet information, at present the software element of web browser commonly used many with picture ActiveX, Java applets, and form utilization＜Insert such as Visual Basic Scrips or＜Object label writes in the html file.Wherein for example adopt the ActiveX programmer can design program, or make an interactively webpage, and supply the deficiency of HTML on interactive ability by data download on the Internet.
Except the web displaying support of browser, the hyperlink of HTML needs also that (Uniform Resource Locator URL) confirms the place of reference resources in conjunction with unified resource location word.URL is mainly used to define territory (domain) name of the relevant agreement of using (protocol), server, port (port) address that interknits and the directory path (directory path) that enters required file.Its form for " Scheme: //Host.Domain[:Port]/Path/FileName " wherein Scheme be the procotol title, for example HTTP or Gopher etc.; And Host is a server name, for example www or ibm etc.; Domain then is a domain name, as microsoft.com or hitek.com.tw etc.; The port numbering of Port for using, this parameter can be omitted usually; Path then is the file name that is connected with FileName, if we omit them, default value that then can using system, just can arrive on the homepage of this website and browse, but, and they are added the speed that will help to seek resource in the word of unified resource location if the user knows Path and FileName.
At present, undertaken by the Internet in the process of message transmission, often, be shown to the user with page format more once with behind the whole end of transmissions of all data.Right because network has the restriction of transmission rate, the situation that therefore user is had in transmission course to wait as long for takes place.Especially when there being mass data to have when pending on the webpage, this method that once shows total data, regular meeting causes the infull phenomenon of transmission.Its reason is because server end adopts dynamic generation web page, when obtaining mass data from certain database, and behind the generation webpage, it is huge unusually that the data in server amount can become, thereby the picture that the viewer often can't be downloaded in the allowed time of transfer of data fully, also or transmission course is made a mistake easily, cause the abnormal end of transmission procedure.
Summary of the invention
And the present invention promptly is directed to this, proposes a kind of idea of segment transmissions data, makes full use of the dynamic characteristic of HTML, and the phase makes transmission course more unobstructed and reduce user's stand-by period and the generation data interruption phenomenon of prevention mass data in transmission course.
In view of many shortcomings that data transmission software produced traditional in the foregoing invention background, the present invention adopts Dynamic Hyper Text Makeup Language (DHTML) technology to realize the continuous biography of network.Its main purpose is and need not can realizes data download and file in this page or leaf through the traditional binary coding, and supports to dynamically update and dynamic reminding in the page or leaf.
Another object of the present invention, being can the segment transmissions data, and in the transmission data, shows the data of being transmitted in same page inter-sync, to reduce user's stand-by period, surfing is accelerated.
According to above-described purpose, the invention provides a kind of server end that can make on the internet in the process of transmission data, show transmission result's method for transmitting sectionally simultaneously with page format.At first, network server end transmits control command, and browser receives the order from server, and this moment, client was then moved initialize routine, understood the message that server end sends.And in the initialization running, also begin to carry out the program of data download, promptly by browser to webserver transmit data request, and after server receives request, just use the server database support program, the data package 1 that calls grouping and setting (being divided into the N group) in regular turn reads the message in the server database to component N.After each group data is downloaded to corresponding html file, then pass the server database support program back the webserver again when the inferior data of calling, via browser, be sent to a page control program, form the page demonstration that the user can see.When carrying out page control program, if reading, the content of respectively organizing data package that discovery server data support program calls do not finish, then this page control program will be got in touch by the browser and the webserver, require server end to continue to read remaining data with the server database support program in data package.In the present invention, the data volume that at every turn can read is automatic setting as required and via the design of program.And then, reaching server continuously with the data that read, the operating procedure that duplicate pages shows is till all data have all transmitted.
Utilize this data transmission method proposed by the invention, not only can make transmission course more smooth and easy, reduce user's stand-by period, and can prevent the data interruption phenomenon in the mass data transmission course.

Embodiment
Principle of the present invention mainly is to be built on the principle of transfer of data between network service end and the client.The function of this software is shown in Fig. 1 with module.And function diagram mainly can be divided into four sections programs according to carrying out character: initialization, data download, page control for the first time show and the subsequent download data.
At first, in first section program 1, network server end transmits control command, and browser receives the order from server, and this moment, client was then moved initialization module, to understand the message that server end sends.The operating process of initialization module can be consulted Fig. 2 herein, one form data control (TDC at first is set, Tabular Data Control) attribute (module 201), specify a data source (Data Source) (module 202) then, that is the specific data position that begins to transmit, this moment, the request server end transmitted data (module 203), and the callback module 204 of call notification client reception data, also comprised the method that readjustment is set in the module 204.The constipation bundle is by the initialization flow process of server end control client.
And in the initialization running, also carry out second section program 2 in the functional module (Fig. 1), beginning is by the server end data download.At first by browser to webserver transmit data request, and after server receives request, just enter the server database support module, the data package 1 that calls grouping and setting (being divided into the N group) in regular turn reads the message in the server database to component N.And this concrete operations flow process by the server end data download is shown in Fig. 3.After network server end receives request from client, promptly begin by server end to the client downloads data, at first receive the instruction (module 301) of transmission data, call data extraction component (module 302) then, as a standard interface, and this data extract also can be developed expanded function according to definition by third party (that is user), for example judges whether to be (N assembly should have N transmission) transfer of data (module 303) first time.If, then directly from assembly, obtain data (module 304), output to (module 305) in the corresponding html file with database format then, then whether the data in the determination component read finish (module 306), if then can finish current operation (module 307), if do not finish when secondary data reads as yet, then remaining data are continued to output in the HTML corresponding document with database format, finish just termination routine operation until downloading when the inferior data of calling.And if after being written into data extraction component, discovery is not the transfer of data first time, judges then whether current transmission is subsequent transmission (module 308).If subsequent transmission then is provided with assembly and reads address (module 309) to the next one, obtain data from this new address of reading, concrete operations are afterwards carried out in regular turn according to module 304 to the operation of module 307 again.But if not subsequent transmission, then discharge current data extraction component (module 310), judge then whether current be data identification operation (module 311).If, sky information (module 312) and termination routine then are set, if not the data discriminated operant, error message (module 313) and reporting errors information (module 314) are set then, and termination routine.And the download of webserver end data is finished.
When data are downloaded to corresponding html file each time, and then the 3rd section program 3 of functional module (Fig. 1) just carry out, to pass the webserver again back by data downloaded in the server database support module, then via browser, be sent to page control module, form the page demonstration that the user can see.
During by page control module, do not finish, then enter the 4th section program of functional module if the content of the data package in the discovery server data support module reads.Page control module will be got in touch by the browser and the webserver, require server end to continue to read remaining data from the data package of server database support module.In the present invention, the data volume that at every turn can read (that is size of assembly) is automatic setting as required and via the design of program.And then, reach server continuously with the data that read, and repeat the operating procedure (for example:, then need repeat N-1 operation) of the 3rd section program 3 of functional module if N group assembly is arranged, till all data have all transmitted.And the page control module of this place utilization, its operating process can be consulted Fig. 4, and a main effect of this module is after client is received data, sends readjustment message to server end, and by the end of server end control data transmission process.At first judge the state (module 401) of form data control, whether this control current state is task completion status (module 402).If do not finish as yet, then return module 401, continue to judge the current state of form data control.But if current form data control is a completion status, then calculate data downloaded (module 403), and the position (module 404) of searching data head (Data Head) automatically, judge whether search action finishes (module), if, page control module EO (module 406) then, but if search action and do not finish, parameter (module 407) is set then, with enforced table forms data control reset (module 408), return module 401 then, continue to judge the current state of form data control.
With an embodiment, specify above-mentioned technology below.When passing through network, during from page browsing one library catalogue, after the user enters the page, be not that by the time data are downloaded fully and can be seen desired data or fileinfo after finishing, but in the process that data transmit, constantly in the page, increase tabulation, with the synchronously and dynamic display column of transport process.Registered the data query assembly of this library catalogue simultaneously at server end, obtained data by this assembly from database, and send the user to, its concrete operations flow process as shown in Figure 5.The webserver (module 501) with the initialization of call list forms data control (module 502) running client, call IIS (Internet Information server, network information server) control (module 503) set up a website, (the Active Server Pages that calls ASP, the dynamic state server webpage) control (module 504) is developed a webpage environment and is called data extraction component (module 505) data download, reading of data (module 506), and then the continuous network information that passes.In conjunction with html web page, and produce and carry out the application program of dynamic, mutual Website server among the embodiment.
The above is preferred embodiment of the present invention only, is not in order to limit claim of the present invention; All other do not break away from the equivalence of being finished under the disclosed spirit and changes or modification, all should be included in the claims.
