Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a page display control device for display control of a page described in a markup language such as HTML (Hypertext Markup Language), for example, a Web page that provides information in a WWW (World Wide Web) system. The present invention relates to a control method and a program recording medium for page display control.
[0002]
[Prior art]
There is a request to change the display content of a Web page provided by the same URL (Uniform Resource Locator) according to a user who accesses the WWW server. Conventionally, in order to change the contents of a Web page displayed for each user who has accessed the WWW server, a special program called CGI (Common Gateway Interface) and a script file corresponding thereto are constructed on the WWW server. The HTML source was created dynamically.
[0003]
[Problems to be solved by the invention]
However, the development and creation of CGI programs and script files requires the acquisition of advanced expertise in programming and development languages, and not everyone can do it easily. However, every time the layout of the Web page is changed, it is necessary to recreate the CGI program or the like according to the changed page and to check the operation.
[0004]
An object of the present invention is to, for example, display a Web page by dividing the HTML source constituting the Web page into a plurality of parts, setting access rights for each part, and changing the contents displayed according to the user. An object of the present invention is to provide an apparatus that can easily construct a page.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has means as shown in FIG.
FIG. 1 shows a block configuration example of a Web page display control apparatus for a Web page described in HTML.
[0006]
The divided file storage means 1 is a means for storing an HTML source file divided for each part having different access authority. The user information storage means 2 is a means for storing user information such as user IDs, passwords, and affiliation groups registered in advance. The configuration information definition storage means 3 is a means for storing definition information as to which one of the divided HTML source files is used to synthesize one HTML source.
[0007]
The access right setting processing means 4 is a means for setting an access right for a user or a user group for each file of the divided HTML source. The HTML synthesis processing means 5 is a means for synthesizing a plurality of divided HTML sources into one HTML source according to the access right of the user. The confirmation processing means 6 is a means for outputting the synthesized HTML source in order to confirm what kind of HTML source is actually generated with the authority for each user. Note that the confirmation processing means 6 may display a Web page based on the HTML source synthesized as necessary.
[0008]
The Web page display control apparatus 10 is connected to a WWW browser 7 on a client terminal (not shown) operated by a user through a communication line 8.
This device operates as follows.
[0009]
When there is a page request from the client terminal, the HTML composition processing means 5 first obtains an HTML file necessary for displaying the Web page from the configuration information defined in the configuration information definition storage means 3. .
[0010]
Next, with respect to the divided HTML file necessary for the configuration of a certain page, it is checked in order from the top one whether or not the currently accessing user has the access right. If the file is accessible as a result of the check, it is used for synthesizing the HTML source sent back to the client terminal, and is not used if it is inaccessible. Repeat this for all defined files. As a result, only the contents of the file with access right are extracted, the HTML source of the request page is synthesized, and transmitted to the client terminal of the requesting user.
[0011]
As a result, even for Web pages with the same URL, various HTML sources can be created and sent back according to the access rights of the accessing user, so that various contents suitable for individual users are displayed. be able to.
[0012]
Also, the HTML processing for displaying the Web page can be confirmed by simulating what kind of HTML source is synthesized for each user by the confirmation processing means 6 and outputting the result. Here, for easy confirmation, for example, the divided HTML file names used for the composition are displayed, and the contents of the HTML source are also displayed with a separator for each used file.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
First, Web page display processing will be described with reference to FIG.
[0014]
User information such as users USER1 and USER2 is registered and stored in the user information storage unit 2 in advance. The user information includes information such as the user ID, password, and affiliation group.
[0015]
The configuration information definition storage means 3 defines configuration information such as a file name necessary for configuring a page with the same URL (Uniform Resource Locator) and a user name permitted to access for each file. For example, as the configuration information of page A, file names (HTMLLa to HTMLd) divided for each part constituting page A and access-permitted user names for the respective files are stored. Also, the divided file storage means 1 stores an HTML file that constitutes a Web page divided into a plurality of parts.
[0016]
In this example, of the files HTMLLa to HTMLd defined in the page A configuration information, the HTMLLa contains information on the header part of the page A, item parts “notice” and “new arrival” as shown in FIG. As shown in FIG. 3B, the content of “information” is shown in FIG. 3B. The content of the item “management information” is shown in FIG. As shown in FIG. 3D, the content of the footer portion is described in HTMLd.
[0017]
When the page A is accessed from the WWW browser 7 of the USER 1 via the communication line 8, the HTML composition processing unit 5 determines the page A based on the page A configuration information stored in the configuration information definition storage unit 3. For the files HTMLLa to HTMLd constituting A, it is checked whether USER1 has the access right. If it is found that USER1 has the access right for HTMLLa, HTMLb, and HTMLd files, only the HTMLLa, HTMLb, and HTMLd files are acquired from the divided file storage means 1, and these HTML sources are transmitted. The data is sent to the buffer and sent to the WWW browser 7 of USER 1 via the communication line 8. Therefore, USER1 browses the page A including the header “WELCOME”, notification, new arrival information, and management information.
[0018]
On the other hand, when page A is accessed from USER2, the same processing is performed by the HTML composition processing means 5, and HTMLLa, HTMLc, and HTMLd files to which USER2 has access right are transferred from the divided file storage means 1. Obtain these, send only these files to the transmission buffer, and send them to the WWW browser 7 of USER2. Therefore, USER2 browses the page A including the header “WELCOME”, information, new arrival information, and technical information.
[0019]
In this way, different contents can be displayed even on pages with the same URL, depending on the access rights of the accessing user.
FIG. 4 is a processing flowchart of Web page display.
[0020]
The Web page display control apparatus 10 waits for an access request (step S1). If there is a request, the Web page display control apparatus 10 acquires an HTML file necessary for displaying the page from the requested URL (step S2). When N = 1 (step S3), the user accessing from the first file determines whether or not the N-th file has access right (step S4). The file is copied to the transmission buffer as an HTML source (step S5). 1 is added to N (step S6), and the processes in steps S4 to S6 are performed for all files defined to constitute the page (N = all defined to constitute the page). Repeat until the file becomes +1 (step S7). Next, the contents of the transmission buffer are transmitted to the client terminal (step S8).
[0021]
Next, the setting of the access right to the divided files constituting the page portion will be described.
FIG. 5 is a diagram illustrating an example of a page management screen. On the page management screen, it is possible to change the page information registered for each page, set the access right for the entire page, and set the page layout. Here, a home page (Home) and pages 1 to 16 are created. In FIG. 5, for the Home: XX business unit main page and the Page1: What's New page, the access right to the entire page is not set (indicated by a white square in the figure). In this figure, the first page (Page 1) of the page list is displayed, but the second page (Page 2) and subsequent pages of the page list can be displayed by scrolling the screen.
[0022]
By clicking a “layout setting” button in the page list, an HTML document can be registered for the page, and users and groups that can access the registered HTML document can be registered / deleted.
[0023]
FIG. 6 shows a page layout setting screen displayed when the “layout setting” button for the home page (Home) in the page list shown in FIG. 5 is clicked. This homepage (Home: XX business unit main page) is composed of frame 1 and frame 2, and the HTML file names used in the header part, item part, and footer part are registered for each. To register an HTML file name, when the triangle button is pressed in the HTML file name column of the item to be registered, a list of file names of HTML files stored in the divided file storage means 1 in FIG. 1 is displayed. This is done by selecting from among them.
[0024]
In this page layout setting screen, the access right for each item part constituting the page can be set based on the user information stored in the user information storage means 2. In this example, access rights are set for the file of item part 2 (Home01b.html), the file of item part 5 (Home02b.html), and the file of item part 6 (Home02c.html) (black in the figure). Indicated by a square).
[0025]
FIG. 7 shows an example of a screen for setting an access right for the HTML file of the item portion. The screen shown in FIG. 7 is displayed by selecting the item part 5 as an access right setting target on the page layout setting screen shown in FIG. 6 and clicking an access right setting button. The access right for the HTML file of each item part can be set using an IP address, a user ID, or a user group name.
[0026]
In the access right setting by the IP address, the IP address is input in the IP address input field. In the access right setting by user ID or group name, the list of accessible users and accessible groups is displayed on the left side of the screen, and the list of inaccessible users and inaccessible groups is displayed on the right side of the screen. After selecting the user name or group name to be changed, use the delete button and the register button to delete or register the access right.
[0027]
In the initial state of access right setting for the item section, all users and groups are registered in the inaccessible list (all may be registered in the accessible list), and this user information and group information are: Obtained from the user information storage means 2 of FIG.
[0028]
The header part and footer part of each page are common to all users and user groups. Therefore, as is apparent from the page layout setting screen of FIG. 6, access rights cannot be set for the header part and the footer part. Therefore, the HTML composition processing means 5 always composes the HTML source by using the HTML file constituting the header part and the footer part regardless of the access right.
[0029]
FIG. 8 is a process flowchart of the access right setting process.
Assume that the access right setting screen for the item section shown in FIG. 7 is called from the page layout setting screen shown in FIG. The access right setting processing means 4 performs the following processing. First, as shown in FIG. 6, a list of IP addresses that can access this item section, accessible users, inaccessible users, accessible groups, and inaccessible groups is displayed (step S11 in FIG. 8).
[0030]
Next, if the change button is pressed, the input in the accessible IP address input column is checked, and the accessible IP address is changed (steps S12 and S13).
[0031]
If the user or group registration button is pressed, the selected user or group is extracted from the list of inaccessible users or inaccessible groups and added to the list of accessible users or inaccessible groups (step S14). , S15).
[0032]
If the user or group delete button is pressed, the selected user or group is extracted from the list of accessible users or accessible groups and added to the list of inaccessible users or inaccessible groups (step S16). , S17).
[0033]
If the access right setting is changed, the access right definition information in the configuration information definition storage unit 3 is updated (step S18). Steps S11 to S18 are similarly repeated until an end instruction such as “return to main”, “return to page management”, or “return to page layout setting” is given (step S19).
[0034]
When the access right is defined, the HTML source actually transmitted to the user can be confirmed by the confirmation processing means 6. Furthermore, not only an HTML source but also a function that enables confirmation of actual page display as necessary may be provided.
[0035]
FIG. 9 shows an example of a confirmation display based on the access right setting in the case shown in FIG. Note that the contents of the HTMLLa to HTMLd files are as shown in FIG. 9A is an example of an HTML source transmitted to USER1, FIG. 9B is an example of a page display to USER1, and FIG. 9C is an example of an HTML source transmitted to USER2. 9D shows an example of page display on USER2. In the display of the HTML source, each used file is displayed with a separator, and a file name is also added to each.
[0036]
Such a confirmation display makes it clear at a glance which HTML file is used for each user, and is convenient for setting confirmation of access rights and investigating setting errors. For example, the confirmation processing means 6 is called by clicking a column such as “Source of frame 1” or “Source of frame 2” on the page layout setting screen shown in FIG. 6 is executed.
[0037]
【The invention's effect】
As described above, according to the present invention, dynamic change for each user of the display contents of a Web page, which conventionally required programming such as a script, can be realized by simply defining it using a GUI. As a result, development costs and operational costs can be significantly reduced. In addition, by having a confirmation display function with authority for each user, it is possible to grasp in detail the status of files that are synthesizing HTML sources, and to efficiently check access right settings and track setting errors. become able to.
