Description

Specification

Method for acquiring information of another domain, and server system and server program used in this method

Technical field

[0001] The present invention relates to a method for acquiring information of another domain, and in particular, while executing a script language (such as Javascript (registered trademark)) complying with security restrictions of HTTP (HyperText Transfer Protocol) clients. The present invention relates to a method for acquiring data in a domain.

Background

[0002] Conventionally, script languages (Javas cript (registered trademark), etc.) that comply with security restrictions of HTTP clients (browser) cannot exchange information between domains even if they display a site in another domain. I couldn't do it.

[0003] The applicant is unaware of the existence of known technical literature relating to this.

Disclosure of the invention

Problems to be solved by the invention

[0004] The present invention improves the inconvenience of the powerful conventional example, and in particular, makes it possible to acquire information of another domain while executing the Script language in accordance with the security restrictions of the HTTP client (browser). This is the issue.

Means for solving the problem

[0005] A first invention for solving this problem is to execute the following steps between HTTP server clients.

[0006] First, the HTTP client in the A domain acquires and executes a script for the A domain or an HTTP server other than the A domain. This script generates and executes a GET statement for the domain B server with arguments. The B domain server system acquires the bow I number from the HTTP client in the A domain via this GET, and executes a predetermined GET handling process that handles this argument.

[0007] According to this, information can be passed from the A domain to the B domain server by the description of the Script being executed in the A domain. [0008] Here, the system of the B domain server may provide the result information of the GET corresponding process to the HTTP client of the A domain as a response to the GET.

[0009] According to this, as a result of requesting information from the A domain to the B domain server by the description of the Script being executed in the A domain, the B domain information can be acquired by the A domain client. .

[0010] Subsequently, the second invention of the present application executes the following steps between HTTP server clients.

[0011] First, an HTTP client in the A domain acquires a Script from the A domain or an HTTP server other than the A domain, and executes the Script. This Script includes an information fragment obtained by dividing an information fragment obtained by dividing the original information, an information piece identifier for identifying the divided information piece, and an identifier of the original information into the B domain server including at least an argument. Run every time. The system of the B domain server associates the information piece acquired through execution of the GET statement, the information piece identifier, and the identifier of the original information of the information piece and stores them in the storage means. Thereafter, the system of the B domain server reads the information piece and the information piece identifier corresponding to the original information identifier from the storage means, and reconstructs the original information from the information piece based on the information piece identifier.

[0012] The length of the argument that can be passed from the client to the server by the GET method is limited, and it is not possible to pass information that is longer than a certain length. However, according to the second invention, it is possible to pass long original information above a certain level to the B domain server by using the GET method.

[0013] Here, the B domain server system generates result information that affects the reconstructed original information, and provides this result information to the A domain HTTP client as a response to the request for the GET statement. May be. In this case, the HTTP client of the A domain can obtain the result information generated in the system of the B domain server as a response corresponding to the GET statement request.

[0014] Subsequently, the third invention of the present application executes the following steps between HTTP server clients.

[0015] First, HTTP client of A domain is A domain or HTTP server other than A domain Power also acquires and executes Scripts. This Script executes a POST with a POST process identifier for the B domain server. The system of the B domain server executes the POST compatible processing corresponding to the POST, and stores the POST compatible processing result in the storage unit in association with the POST processing identifier added to the POST. Script executed by HTTP client of A domain executes GET with GET processing identifier to B domain server. The B domain server system executes a GET corresponding process corresponding to this GET, and stores the GET corresponding process result in the storage means in association with the GET process identifier added to the GET. Then, the B domain server system reads the POST processing result and the GET processing result corresponding to the POST processing identifier and the GET processing identifier from the storage means, and affects the POST processing result and the GET processing result. Generate combined result information.

[0016] In the second invention described above, it has been described that long information exceeding the limit of the GET method can be passed to the server. However, depending on the length of the information, it may be necessary to execute 3 or more GET methods. On the other hand, according to the third invention combining POST and GET, for example, most of the long information is passed to the server by POST, and the information passed by GET is limited to the length within the limit of GET. By executing each GET once, it is possible to pass long information to the server.

[0017] Here, the system of the B domain server may provide the composite result information to the HTTP client of the A domain as a response to the GET or POST.

[0018] Further, in the first to third inventions, it is possible to select result information (response) to be returned from the B domain server to the A domain client. For example, if the result information is returned as Script, new processing can be given to the client. However, there is a risk that an illegal script provided from the B domain server to the A domain client will be executed. Therefore, the result information returned from the server to the client may be a style sheet such as CSS, and information from the B domain sano may be given to the A domain client as information in the style sheet. The result information given from the server to the client is an object (for example, image) with attributes (for example, the width and height of the image), and the attribute of the object is A as information from the B domain server. Give it to domain clients. [0019] In the above description, "A domain" and "B domain" only indicate that they are different domains (different domains), and the names "A" and "B" are not important. Absent.

The invention's effect

[0020] According to the present invention, as described above, it is possible to acquire information of another domain while executing the Script language in accordance with the security restrictions of the HTTP client (browser).

BEST MODE FOR CARRYING OUT THE INVENTION

[0021] Configuration Common to Each Embodiment>

In the following, embodiments of the present invention will be roughly classified into three types. Before that, the system configuration common to each embodiment will be described. For example, as shown in FIG. 1, according to the embodiment of the present invention, an HTTP client executed in a user terminal device is configured such that an A domain HTTP server (hereinafter referred to as A server) and a B domain executed in a server system. It communicates with HTTP server (hereinafter referred to as B server! /).

[0023] A terminal device that executes an HTTP client includes a computer (processing means) that executes program processing, and a storage device (storage means) such as RAM, ROM, and HDD that stores information handled by the program. . It also has a communication device (communication means) such as a modem for communicating with the HTTP server via the Internet. The program executed by the computer and the information handled by the program are stored in the storage means and read from the storage means in a timely manner! / Speak.

Similarly, a server system that executes an HTTP server also includes a computer (processing means) that executes program processing, and a storage device (storage means) such as a RAM, ROM, and HDD that stores information handled by the program. It has. It also includes a communication device (communication means) such as a modem for communicating with the HTTP server through the Internet. The program executed by the computer and the information handled by the program are stored in the storage means in a timely manner, and the storage means power is also read out. The operations described below are realized by executing a computer power program of the terminal device and the server system.

[0025] First Embodiment: Method Using Single GET>

[0026] Based on the above configuration, the operation of the first embodiment of the present invention will be described first. Figure 1 3 is a flowchart showing the operation of the first embodiment.

[0027] First, the HTTP client of the A domain acquires and executes the script of the A server power (SI 1, S12). “A domain HTTP client” means an HTTP client displaying a page obtained from the A domain server. The Script acquired from the A server is a Script language that complies with the security restrictions of the HTTP client. In this embodiment, JavaScript (registered trademark) is adopted. This Script may be sent to the HTTP client in the state embedded in HTML (HyperText Markup Language), or the HTML being executed in the HTTP client may read and execute the A server script.

[0028] The Script dynamically generates and executes a GET statement addressed to the B server with an argument (S13, S14). For example, Script can dynamically generate a GET statement using the CreateElement method or the document.write method. As a result, the above script generates and reads the following tag, for example, so that a GET request to the B server is executed.

[0029] [Equation 1]>

[0030] The system of the B server acquires an argument from the HTTP client in the A domain via this GET, and executes a predetermined GET handling process that handles this argument (S15). As a result, the B server can obtain information from the HTTP client of the A domain which is another domain. The B server system processes the GET argument by cgi such as perl or servlet, and stores the result information of the corresponding GET compatible processing in the storage means.

[0031] Then, as a response to the GET, the system of the B server reads out the result information of the GET corresponding process from the storage unit and provides it to the HTTP client in the A domain (S16). The HTTP client in domain A obtains the result information corresponding to GET from Bsano and executes a predetermined process for handling the result information (S17). As a result, the HTTP client of the A domain can obtain the information provided from the Sano of the B domain. In addition, by setting the result information corresponding to GET as Script, HTTP client of A domain New processing can be given to the event.

[0032] <Second Embodiment: Multiple GET Method>

Next, a second embodiment of the present invention will be described with reference to FIG.

[0034] First, an A domain HTTP client obtains a Script from the A domain HTTP server.

The Script is executed (S21, S22). This operation is performed in steps S 11 and S of the first embodiment.

Same as 12.

[0035] In this embodiment, the Script executed by the HTTP client of the A domain includes an information piece obtained by dividing the original information, an information piece identifier for identifying each divided piece of information, and identification of the original information. Generate and execute multiple GET statements addressed to the B domain server including the child as an argument for each piece of information (S23, S24). Here, the original information is the information passed from the A domain HTTP client to the B server. In the present embodiment, the original information is intended to be relatively long information that cannot be passed due to limitations in the GET method. For example, assume that the original information is the following argument.

[0036] name = ogawa & date = 20060531 & domain = kawachi.com & path = index.html & permission = ail & perfect

Script divides the above original information according to a predetermined rule and divides it into a plurality of information pieces. An information piece refers to an element constituting original information. There are various ways to divide the original information into pieces of information.For example, it can be divided into a certain number of characters, divided into even-numbered and odd-numbered characters, and `` & It is good also as a piece of information divided | segmented for every variables, such as name, date, and domain. In addition, for example, one information piece may have some elements overlapping, such as name = ogawa & date = 20060531, and the other information piece may be date = 2006053 l & domain = kawachi.com. If one piece of information fits in the length of information that can be passed by GET, the rule of division is irrelevant.

[0037] In addition, the Script sets an information piece identifier for each information piece in order to identify the divided pieces of information from each other. The information fragment identifier may be given by, for example, a sequence number such as 1, 2, 3,..., Or when the information fragment is divided for each parameter as described above, Variable names of parameters such as name and date may be used as information piece identifiers.

[0038] The Script gives an identifier of original information to each piece of information. This is a re-creation of the original information. This is because the information pieces necessary for the configuration can be selected on the server side based on the identifier of the original information. As the identifier of the original information, the same identifier may be given for each information piece, or a different identifier may be given to the information piece. If different identifiers are given to pieces of information, a method for associating the different identifiers with the common source information is registered on the server side, and the server system refers to the method for associating with the source information. It is conceivable to select the information piece.

[0039] The method for generating and executing the GET statement by the Script is the same as in the first embodiment, but in this embodiment, the GET statements are generated as many as the number of information pieces to be passed to the B server. In each GET, the entity of the information piece, the identifier of the information piece, and the identifier of the original information of the information piece are embedded as arguments and passed to the B server.

[0040] The system of the B server stores the information piece acquired through the execution of the GET statement, the information piece identifier, and the identifier of the original information of the information piece in association with each other. When the storage of a plurality of information pieces is completed, the system of the B server reads the information piece corresponding to the original information identifier and each information piece identifier from the storage means, and based on the information piece identifier. The pieces of information are combined to reconstruct the original information. As a result, the system of the B server can acquire the original information passed from the HTTP client of the A domain, and can acquire long information exceeding the limit of GET. However, even if not all of the elements that make up the original information are available, the server B system can start processing when the information necessary to execute the GET-compatible processing is available. At this time, the B server system instructs the A domain HTTP client to stop executing subsequent GETs when the information necessary to execute the GET compatible processing is complete, and In response to this instruction, the HTTP client may cancel the GET to send information pieces that have not been sent to the B server.

The system of the B server executes a predetermined GET handling process corresponding to the GET (S25), and dynamically generates result information in which the reconstructed original information is affected. Then, this result information is provided to the HTTP client in the A domain as a response to the GET request (S26). HTTP client of domain A acquires the result information dynamically generated in the system of server B as a response corresponding to the above GET request, and this result information A predetermined process for handling is executed (S27). Execution power of this GET support processing (S25) The processing from the result information handling (S27) is the same as the processing from step S15 to S17 in the first embodiment. You can obtain the information provided from the start.

[0042] <Third embodiment: Method using a combination of POST and GET>

Next, a third embodiment of the present invention will be described with reference to FIG. In the second embodiment, long information exceeding the limit of the GET method can be passed to another domain server while using the GET method. However, it involves processing of combining multiple pieces of information on the server side and reconstructing the original information. Therefore, this embodiment proposes a mechanism that can pass long information exceeding the GET limit to a server in another domain, as in the second embodiment, and is simpler than the second embodiment.

[0044] First, the HTTP client of the A domain acquires and executes the Script from the HTTP server of the A domain (S31, S32).

[0045] This script generates and executes a POST statement with a POST process identifier for server B

(S33, S34). The POST processing identifier and GET processing identifier are identifiers for processing by associating information passed separately by POST and GET on the server side. The POST processing identifier added to POST and the GET processing identifier added to GET described later can be the same or different values. When the related POST and GET processing identifiers are the same, the B server system performs processing using the POST and GET arguments that match the POST processing identifier and the GET processing identifier. On the other hand, if the related POST and GET process identifiers are set to different values, a method for associating the POST process identifier with the GET process identifier in the B server system is registered in advance, and the corresponding action is based on this method. Get each argument from the combination of POSTAGE T and use it for processing.

Here, the method of associating the POST process identifier with the GET process identifier is not necessarily registered in advance on the server side. For example, a method for associating a POST process identifier with a GET process identifier may be passed from the client to the server during POST from the client to the server.

[0046] [Equation 2] When passing information from the A domain HTTP client to the B domain server via POST, 1W generates the following F0EM tag using imierHTML of Javascript.

<form id = post form act i on = http://aomainb.com/biivreceivepost.cgi method = PQ,

Then, send the FOEM value to the server as follows.

var elem = document .setEl ementByldi, postform ");

elem.submitO;

Then, the following values are passed to the server

dd

[0047] The system of the B server executes a predetermined POST corresponding process corresponding to the POST, and stores the POST corresponding process result in the storage unit in association with the POST process identifier added to the POST (S35, S36). . As a result of processing corresponding to POST, information passed by POST may be stored as it is, or a predetermined process using information passed by POST may be executed, and an execution result of the processing may be stored. .

In this embodiment, the server B system returns a response (POST completion notification) corresponding to the POST to the HTTP client (S37). When this response arrives at the HTTP client, the Script being executed by the HTTP client in the A domain performs the following processing.

[0049] The Script generates and executes a GET statement with a GET processing identifier for the B server (S38, S39). The method of executing GET from the A domain HTTP client to the B server is the same as the steps S13 and S14 in the first embodiment. For example, the following parameters are sent to the B server.

date = 20060531 & domain = kawachi.com & getid = getia_xyz

[0050] The B server system executes a GET corresponding process corresponding to this GET (S40), and stores the GET compatible process result in the storage means in association with the GET process identifier added to the GET. As the GET corresponding processing result, the information passed by GET may be stored as it is, or a predetermined process using the information passed by GET may be executed and the execution result of the processing may be stored. [0051] After that, the system of the B server reads the POST processing result and the GET processing result corresponding to the POST processing identifier and the GET processing identifier, and stores these POST processing results and the GET processing result. Generated composite result information is generated (S41, in the above example, the postid_xyz and getid_xyz processes are associated with each other). Here, influencing means that the composite result information is obtained as an output in which the POST processing result and the GET processing result are input to a predetermined function.

[0052] The B server system provides the composite result information to the HTTP client in the A domain (S42). The HTTP client of the A domain acquires composite result information such as script provided from B Sanoku, and executes a predetermined process for handling the composite result information (S43).

Here, in the present embodiment, the power of executing the GET after the POST. The present invention is not limited to this order. The GET may be performed first and the POST may be performed later. The Script being executed in the HTTP client may execute the other GET or POST request without waiting for the POST or GET completion notification. Also, the execution of GET is not limited to once. You can combine GET and POST multiple times as in the second embodiment.

[0054] <Example 1 of Result Information>

[0055] The power described above for the three embodiments will be described below with reference to result information passed from the B server to the HTTP client in the A domain as a result of GET or POST processing.

In each of the above embodiments, Script is considered as an example of result information returned from the B server to the HTTP client. By passing Script from the B server to the A domain HTTP client, the B domain power can also control the A domain. However, if the Script prepared in the B domain is an illegal script, there is a risk that the illegal script will be executed in the A domain! Therefore, the result information sent from the B server to the HTTP client in the A domain may be a style sheet such as CSS (Cascading Style Sheets). It is possible to control the A domain from the B domain force by passing the style sheet from the B domain to the HTTP client of the A domain. If the interpretation of the style sheet description is negotiated in advance between the B server and the HTTP client of the A domain, control beyond the range that can normally be controlled by the style sheet becomes possible. [0057] Example 2 of Result Information>

[0058] Next, as a result information to be passed from the B server to the HTTP client in the A domain, a script passing power is introduced. A method of giving the script power ¾ OM object attributes and the type or number of DOM objects as information is introduced. For example, if the following description is written in the Script of the result information, 250 px can be obtained.

[0059] [Equation 3] That is, the following description is included in the confectionery information of the B server umbrella,

<P

return value from ksraclii .com </ p> And the value of variable e 1 em can be obtained by the following Scr i pt.

var el em-document .setEl ementBy Id (aivid> .sty 1 e .wi th;

[0060] Example 3 of result information>

[0061] Next, a method for passing an object with attributes as result information passed from the B server to the HTTP client in the A domain is introduced. For example, an image is passed as result information passed from the B server to the HTTP client in the A domain. The Script being executed by the HTTP client can acquire, for example, the width of the image as an attribute of the image and use it as information. For example, the width information of three images can be acquired by the following script.

var-n w Arra ();

http / / www .domainb .com / i mages / sono3.j S

[0063] Example 4 of Result Information>

[0064] In the third example of the result information described above, an example is given of obtaining an image from B Sano to a client in the A domain and obtaining width information of the image. Next, you can set attributes such as this width information. Introduce how to use and get more information. For example, in the first embodiment shown in FIG. 1, the script being executed on the client repeats the processing from steps S13 to S17 until the condition is satisfied by the do loop. At this time, the result information requested to the B server is an image (object), and an image with a predetermined width and height (attribute) is repeatedly acquired as the result information. During this time, the script of the client counts the number of image acquisitions in the storage means. Each time the script acquires an image while rotating the loop, it checks the width and height of the acquired image (using the result information example 3), and the width and height of the image are preset values. If an image that matches is acquired, the loop is terminated. Then, the number of loop iterations when the loop is exited is read out from the memory means, and the number of iterations is used as information.

According to this, in the B server, desired information can be given to the A domain by intentionally controlling attributes such as the width of the image. The above description can be realized by repeating steps S23 to S27 in the second embodiment, and repeating steps S33 to S43 in the third embodiment.

[0066] Variation common to each embodiment: Script acquisition source>

[0067] By the way, in the first to third embodiments, it is assumed that a script to be executed by a client of A domain is acquired from a server of A domain (steps S11, S21). , S31). However, it is possible for A domain clients to acquire and execute scripts from servers other than A domain. For example, in each of the above embodiments, a script acquired as B domain force result information can be executed by a client in the A domain.

[0068] Examples common to each embodiment: Introduction of application embodiments>

[0069] Finally, embodiments of an information providing system to which the above embodiments are applied will be introduced. FIG. 4 is a block diagram showing the configuration of this information providing system.

[0070] Any of the first to third embodiments described above is executed between the HTTP client of domain 3 and the server of domain 2. Here, the HTTP client that opens page 3 of domain 3 corresponds to the HTTP client of domain A that has appeared in the first to third embodiments. The domain 2 server corresponds to the B domain server. [0071] In the information providing system shown in FIG. 4, the script being executed on page 3 of domain 3 sends a request to domain 2 server in a timely manner, and the information placed on domain 2 server is used as result information. Have acquired. This acquisition of request and result information is repeatedly performed in a timely manner by the operation of the first to third embodiments.

[0072] On the other hand, page 1 opened in the HTTP client of domain 1 which is another domain pops up page 2 of domain 2 to pass information to the domain 2 server. Information to the domain 2 server via POST. The domain 2 server reflects the domain 1 information passed from page 1 via page 2 and creates or updates new information in the storage means. The domain 2 server provides the information thus generated or updated to page 3 of domain 3 as result information for the request from page 3 of domain 3.

[0073] To explain this with a specific example, for example, page 3 of domain 3 provides a map sharing site to user Y and displays a map image. The domain 2 server has coordinate data for raising a flag on the map, and user Y browses the map with the flag raised based on the coordinate data.

On the other hand, page 1 of domain 1 provides user X with a map display site different from domain 3. On this domain 1 map display site, user X can set a flag on the map being viewed. When User X raises a flag on the map being viewed, the coordinates of that flag are sent to the Domain 2 server via Domain 2 page 2 at a predetermined timing. The domain 2 server system updates the coordinate data of the flag set by user X to the database.

[0075] After that, when the update of flag coordinate data is requested from page 3 of domain 3, the current flag coordinate data is sent to the script of page 3 as result information for the request, and user Y browses it. The display of the flag is updated in the map. In other words, the flag set by user X in domain 1 appears on the map that user Y is browsing in domain 3.

As described above, various embodiments and examples have been introduced, but the application of the present invention is not limited to these, and can realize various forms.
