FIG. 1 is an image diagram showing a communication image between the communication message conversion device 1 according to the embodiment of the present invention and the client terminal C and the server S.

The client terminal C is, for example, a personal computer or the like owned by a company employee to perform business processing. Here, the change of the client terminal C environment means the version upgrade of the WEB browser in the OS update of the client terminal C (for example, the version upgrade from IE (Internet Explorer) 10 to IE11, or the change of the browser from IE to Google Chrome. ) Etc., and the term before the change of the client terminal C environment means before the update, and the term after the change means after the update.
Further, the server S is, for example, an in-house server (business server) that performs business processing in response to a request from the client terminal C.

FIG. 1A is a communication image before the change of the client terminal C environment, and FIG. 1B is a communication image after the change of the client terminal C environment. When the business application 202 or OS 203 is updated to become the business application 212 or OS 213, the WEB browser 201 is also upgraded like the WEB browser 211.

At that time, in the client terminal C after the environment change, the layout of the business application running on the client terminal C may be disrupted or malfunction may occur due to the version upgrade of the WEB browser. In such a case, it is generally necessary to modify the program on the server S side according to the client terminal C side after the update, so that the modification and verification require a great deal of time and cost.

Therefore, in the communication between the client and the server after the environment change, the communication message conversion device 1 is used to convert the response from the server S according to the specifications of the WEB browser of the upgraded client terminal C, so that the server S can be used. It is possible to eliminate the need for program modification.

FIG. 2 is a functional block configuration diagram showing a communication message conversion device 1 according to an embodiment of the present invention. In FIG. 2, the communication message conversion device 1 according to the embodiment of the present invention includes a communication unit 11, a recording unit 12, a conversion unit 13, a static replacement unit 14, and a dynamic replacement unit 15.

The communication unit 11 communicates with the client terminal C and the server S via a network communication network such as LAN (Local Area Network) or WAN (Wide Area Network). Further, the received communication messages from the client terminal C and the server S are analyzed, and the communication messages are distributed to the above-mentioned units 12 to 15.

The recording unit 12 records a communication message between the client terminal C and the server S. Further, the request from the client terminal C and the response returned from the server S in response to the request are linked and recorded as the linking information.

Based on the response from the received server S, the conversion unit 13 creates a template response according to the specifications of the WEB browser after the change of the client terminal C environment for each language included in the response.

The static replacement unit 14 adjusts the response from the server S received after the change of the client terminal C environment to the specifications of the WEB browser after the change of the client terminal C environment based on the association information recorded by the recording unit 12. Replace with the matched template response.

The dynamic replacement unit 15 reflects the variable information included in the response from the received server S in the response replaced by the static replacement unit 14.

The response created by the static replacement unit 14 and the dynamic replacement unit 15 is transmitted to the client terminal C via the communication unit 11.

The communication message conversion device 1 can also be realized by executing a communication message conversion program on a computer for functioning as the above-mentioned units 11 to 15.

(Example)
A communication message conversion method using the communication message conversion device 1 will be described with reference to the flowchart shown in FIG. The communication message conversion method includes a linking method shown in FIG. 3 (A) and a replacement method shown in FIG. 3 (B). The associating method is performed before the change of the client terminal C environment, and the replacement method is performed after the change of the client terminal C environment.

[How to tie]
First, the associative procedure will be described with reference to the flowchart shown in FIG. 3 (A). The communication unit 11 of the communication message conversion device 1 relays the communication between the client terminal C and the server S (see FIG. 2). When the associating process is started, the communication unit 11 that has received the request from the client terminal C notifies the recording unit 12 of the request, and the recording unit 12 records the request contents (S101, S102). Then, the request is transmitted (relayed) from the communication unit 11 to the server S (S103).

The server S that has received the request performs business processing in response to the request and returns a response to the client terminal C (S104).

The communication unit 11 that has received the response from the server S notifies the recording unit 12 of the response, and the recording unit 12 records the response content (S105, S106).

Further, the recording unit 12 associates the request recorded in S102 with the response (what kind of request is returned and what kind of response is returned) and records it (S107).

Further, based on the response, the recording unit 12 creates a template response according to the specifications of the WEB browser after the change of the client terminal environment for each language included in the response (S108). Creating for each language means, for example, creating a template response for each HTML, CSS, and Javascript (registered trademark). As the template response, a file according to the specifications of the WEB browser may be prepared in advance for each page displayed on the WEB browser, or may be prepared or created by any other method.

Then, the response is transmitted (relayed) from the communication unit 11 to the client terminal C (S109).

[Change of client terminal C environment]
After implementing the linking method, the client terminal C environment is changed. The change may be made manually by the owner of the client terminal C, the automatic update function of the OS or the like may be used, or any other method may be used. The completion of the change may be visually confirmed by the owner of the client terminal C, a completion notification may be sent from the client terminal C to the communication message conversion device 1, or any other method may be used. After the change is completed, the communication message conversion device 1 switches the process from the associating method to the replacement method.

[Replacement method]
Next, the replacement procedure will be described with reference to the flowchart shown in FIG. 3 (B). When the replacement process is started, the communication unit 11 that has received the request from the client terminal C notifies the recording unit 12 of the request, and the recording unit 12 records the request contents (S201, S202). Then, the request is transmitted (relayed) from the communication unit 11 to the server S (S203).

The server S that has received the request performs business processing in response to the request and returns a response to the client terminal C (S204).

The communication unit 11 that has received the response from the server S notifies the static replacement unit 14 of the response (S205). The static replacement unit 14 replaces the response with a template response that matches the specifications of the WEB browser after the change of the client terminal C environment prepared in S108, based on the association information recorded in S107 by the recording unit 12 ( S206).

Explaining with reference to FIGS. 4 and 5, when the WEB browser after the change of the client terminal C environment is IE11 and the WEB browser of the server S (that is, the WEB browser before the change of the client terminal C environment) is IE6. As shown in (1) to (2) of FIGS. 4 and 5, the response (IE6) received from the server S is replaced with the template response (IE11).

As a result, even if the response received from the server S contains a tag that cannot be used in IE11, it can be easily and collectively converted into a tag that can be used by replacing it with a template response (FIG. 5). reference).

In this way, even if the WEB browser before the change of the client terminal C environment is IE6 and the WEB browser after the change has a different browser version such as IE11, the specifications of the WEB browser after the change (IE11 specifications) are met. Since the correct communication message is converted, the layout is not broken or the characters are not garbled on the WEB browser of the client terminal C.

In addition, high-precision conversion can be performed even for a language (Javascript (registered trademark), etc.) that cannot be simply converted, which is included in a communication message related to the screen configuration of a WEB browser.

After such static replacement is performed, the dynamic replacement unit 15 reflects the variable information included in the response in the response replaced by the static replacement unit 14 in S206 (S207). The variable information is variable information included in the response returned by the server, for example, a user's screen input, a database acquisition result's screen display, and the like. Specifically, when logging in to the business system by entering an individual ID and password for each user from the screen (WEB browser), "Welcome xx (ID)" and "Welcome xx (user)" displayed at the time of login are displayed. It is a display such as "name)".

Explaining with reference to FIGS. 4 and 5, as shown in (2) to (3) of FIGS. 4 and 5, the value (date) of the server processing result is reflected in the response replaced by the static replacement unit 14. ..

Therefore, by changing the variable information according to the specifications of the WEB browser after the change of the client terminal C environment, garbled characters and lack of display information do not occur on the WEB browser of the client terminal C.

Then, the response is transmitted (relayed) from the communication unit 11 to the client terminal C (S208). Since the response is converted according to the specifications of the WEB browser after the change of the client terminal C environment, layout collapse, malfunction, etc. do not occur in the screen display corresponding to the response.

In this way, even if the version of the WEB browser used on the client terminal C changes due to a system update, etc., the user can continue the operation without worrying about it and without the need to modify the program on the server side. can.

Further, this embodiment is an example, and the communication message conversion device 1 can also be realized by executing a communication message conversion program for functioning as each unit 11 to 15 on the client terminal C.

The communication message conversion method of the present invention is useful as a communication message conversion method that absorbs differences in WEB browser versions that occur in updates of the OS, business applications, WEB browsers, etc. of client terminals, and is particularly included in communication messages. It is suitable as a communication message conversion method that is not affected by the language.
