Embodiment
Below, accompanying drawings is used the client server system of an embodiment of the present invention.Fig. 1 represents the whole pie graph of the client server system 1 of present embodiment.Native system 1 has server 10 and client 20.In Fig. 1, client 20 is 1, but also can have many.Server 10 is connected by for example internet, LAN networks (not shown) such as (Local Area Network) with client 20.
In client 20, Web browser 21 and socket Department of Communication Force 25 are installed.Client 20 can use Web browser 21 to obtain various information from Web server, and display unit (not shown, below identical) is shown.At this moment, Web browser 21 sends HTTP (HyperText Transfer Protocol) request to Web server, as the http response to it, obtains the various information of recording and narrating with HTML (HyperText Markup Language).Therefore, native system 1 is the what is called towing type system that initiatively obtains information from client 20.
In the present embodiment, Web browser 21 also has request distribution instruction unit 22.Request distribution instruction unit 22 receives page or leaf switching command (being described in detail later) from server 10, asks the indication of issuing according to the page or leaf switching command that is received.For example, comprise URL in the page or leaf switching command, the 22 indication distribution of request distribution instruction unit are used to obtain the request by the specific Web page or leaf of this URL.Request distribution instruction unit 22 can for example be called as that the application software of applet realizes by reading.
State notifying handling part 14 and relay process portion 15 for example also can be used as, and DLL (DynamicLink Library) realizes.
State notifying handling part 14 returns to the response of Web browser 21 according to Web server 11, gives sequential control portion 12 state notifying of Web browser 21.
In being stored in the Web page or leaf of content stores portion 17, comprise the demonstration page or leaf that has been determined in advance DISPLAY ORDER (sequence).For example, in the Web of relevant authentification of user page or leaf, Web browser 21 is shown according to the order of idle screen → authentication starting image → authenticate-acknowledge picture → individual picture.
In addition, Web server 11 generates the page or leaf switching command according to the request from client, and is notified to client-side management portion 13 by relay process portion 15.For example, if the client different with the client that sends request sent the page or leaf switching command, then can control the display frame of other clients from certain client.At this moment, in request, comprise the URL of the page or leaf that makes demonstration and the IP address of the object client that makes this page of demonstration etc.The thread that this processing can be used as in the Web server 11 is realized.
That is, native system 1 to be client 20 substantially initiatively obtain the drag kick of information from server 10, promote client 20 but generate page or leaf switching commands by sequential control portion 12, can force to make client 20 to carry out drag kick.
The rise time of page or leaf switching command can be above-mentioned random time in addition.For example, also can generate page or leaf switching commands by sequential control portion 12 according to notice from not shown application program etc.
The connecting portion that socket Department of Communication Force 16,25 is to use socket to connect mutually.Therefore, client 20 and server 10 are except that carrying out based on the communicating by letter of HTTP, and the connection that can use socket Department of Communication Force 16,25 to set up based on socket communicates.
Socket Department of Communication Force 16 for example basis is set up the connection based on socket from the request of the socket Department of Communication Force 25 of client.The IP address of the client that has connected also can be registered in the client data table 19.Client-side management portion 13 utilizes this connection, sends the page or leaf switching command that is generated by sequential control portion 12.
The object client that client-side management portion 13 management servers 1 carry out sequential control.Client-side management portion 13 has the client data table 19 of the client of registered sequential control object.Client data table 19 is for example shown in Figure 2, has the IP address 191 and the ID192 that is used at the server identify customer end of client.If with reference to this tables of data, then can know the client of sequential control object.
Below, the flow chart of use Fig. 3 illustrates in the native system 1 with said structure, server 10 is forced to make client 20 carry out a page switching processing step.
At first, sequential control portion 12 to the 13 acquisition request ID of client-side management portion, obtains the ID (S11) that is registered in the client in the client data table 19 by relay process portion 15.Sequential control portion 12 generates the page or leaf switching command, is notified to client-side management portion 13 (S12) by relay process portion 15.In the page or leaf switching command, added and sent ground ID.Client-side management portion 13 is converted to the IP address to this ID, sends the page or leaf switching command from socket Department of Communication Force 25 to client 20.
In client 20, request distribution instruction unit 22 is obtained a page switching command by socket Department of Communication Force 25, and 21 distribution of indication Web browser are used for obtaining the page or leaf (S14) of the URL that page switching command comprises.Web browser 21 is asked (S15) according to this indication to server 10 distribution.At server 10, Web server 11 returns response (S16) according to request.Web browser 21 is accepted this response, switches the page or leaf (S17) that display unit is shown.
As a result, server 10 can force to make client 20 to carry out the page or leaf switching.
Below, the processing of the sequential control portion 12 when using the content that the flowchart text DISPLAY ORDER of Fig. 4 is determined in advance.Herein, the order of example is by the authentication procedure that shows that page or leaf 1 (idle screen) → demonstration page or leaf 2 (authentication starting images) → demonstration page or leaf 3 (authenticate-acknowledge pictures) → demonstration page or leaf 4 (individual pictures) constitute.In this program, though the demonstration time that shows page or leaf 2 and show page or leaf 3 when also not transferring to next picture, show page or leaf 1 as then returning through the regular hour.
Switching to 2 o'clock (S23 is for being) of demonstration page or leaf,,, judging whether the time of demonstration page or leaf 2 surpasses official hour (S24) so change next step over to owing to meet order.When the demonstration time that shows page or leaf 2 surpasses official hour (S24 is for being), return step S21, make and force to show page or leaf 1.When not surpassing official hour (S24 is for denying), sequential control portion 12 monitors the state variation of clients 20, judges to show whether page or leaf switches (S25).When showing that page or leaf has switched (S25 is for being), judge whether the new demonstration page or leaf that shows is to show page or leaf 3 (S26)., do not switching to demonstration page or leaf 3 o'clock (S26 is not) herein, owing to do not meet in proper order, sequential control portion 12 generates the page or leaf switching command that makes demonstration page or leaf 2, sends to client 20, makes demonstration page or leaf 2, returns step S24 (S31).
Switching to 3 o'clock (S26 is for being) of demonstration page or leaf,,, judging whether the time of demonstration page or leaf 3 passes through official hour (S27) so change next step over to owing to meet order.When the demonstration time that shows page or leaf 3 surpasses official hour (S27 is for being), return step S21, make and force to show page or leaf 1.When not surpassing official hour (S27 is for denying), sequential control portion 12 monitors the state variation of clients 20, judges to show whether page or leaf switches (S28).When showing that page or leaf has switched (S28 is for being), judge whether the new demonstration page or leaf that shows is to show page or leaf 4 (S29)., do not switching to demonstration page or leaf 4 o'clock (S29 is not) herein, owing to do not meet in proper order, sequential control portion 12 generates the page or leaf switching command that makes demonstration page or leaf 3, sends to client 20, makes demonstration page or leaf 3, returns step S27 (S32).Switching to 4 o'clock (S29 is for being) of demonstration page or leaf,, continuing the individual picture of demonstration owing to meet order.Like this, server 10 can be controlled the order that makes client 20 picture displayed.
Below, in conjunction with Fig. 5 explanation in native system 1, the treatment step of server 10 when client 20 is accepted commodity etc. and ordered goods.
At first, the Web server 21 of client 20 shows the order picture that is used to import order.The user who is using client 20 sends request (S41) to this picture input necessary information to server 10.When Web server 11 was accepted this request, the affirmation picture that expression has been accepted and order for goods returned to Web browser 21 (S42) in response.
Then, Web server 11 indicates the order handling portion 30 of the order handling of carrying out regulations such as stock's affirmation to handle (S43).Order handling portion 30 is when finishing predetermined process, with this result notification sequential control portion 12 (S44).Sequential control portion 12 generates the page or leaf switching command that makes the order result screen that shows expression order result, sends to client 20 (S45, S46) by client-side management portion 13.
In client 20, request distribution instruction unit 22 is accepted this instruction, and 21 distribution of indication Web browser are used to obtain the request (S47) that shows page or leaf 3.Web browser 21 is accepted this request, to Web server 11 acquisition request order result screen, and shows the picture that is obtained.
Like this, after accepting request, owing to must carry out certain processing, even so in the time can not returning result at once, also can earlier the Temporary Response (S42) for request (S41) be returned, with the time announcement client that processing finishes, make client obtain the demonstration page or leaf that shows result by server.That is, according to present embodiment, in towing type client server system, the propelling movement that server can force client to be pulled.
