Description

A method and device for splitting and reinstalling web applications

technical field

The invention relates to the field of network communication, in particular to a method and device for splitting and reassembling Web applications.

Background technique

In recent years, with the rapid development of the Internet, the Internet has gradually replaced radio, newspapers, and television as the most important means for people to obtain information. In addition, the network is also playing an increasingly important role in people's daily study, work, leisure and entertainment.

A web application is an application program that can be accessed through the web. An obvious advantage of Web applications is that users only need to have a browser to access the application without installing other software, which brings great convenience to users.

A web application is composed of various web components (web components) that complete specific tasks, and expose services to the outside world through the web. In practical applications, Web applications are composed of multiple Servlets, JSP pages, HTML files, and image files. All these components coordinate with each other to provide users with a complete set of services. Counters, message boards, login systems, chat rooms, forum BBS, etc. are all common web applications. With the continuous improvement of user needs and the continuous development of computer technology, the functions of web applications are becoming more and more powerful. At the same time, its structure It's also getting more complex.

In the fields of Internet public opinion monitoring and network data retrieval, it is necessary to collect information in Web applications. Because Web applications contain a lot of information, users may only be interested in some of the information, so it is necessary to analyze the Web applications to extract the information that users are interested in. In addition, the current web applications are all created by website developers, and the functions of the web applications are also set by the website developers, but the functions set by the website developers may not meet the needs of users. For example, a user wants to display the current weather conditions and the current traffic flow conditions of a certain place on the same web page, but these two types of information can only be obtained from different web applications (such as a web application about weather conditions and a web application about traffic flow conditions). status web application) to obtain. In order to meet such needs of users, it is necessary to disassemble and reinstall existing web applications.

Although a web application includes one or more web pages, the methods for splitting web pages in the prior art are usually not directly applicable to web applications. This is because there are a large number of user interactions, subpage calls and other operations in the web pages contained in the web application, which requires that the process continuity and data integrity of the web application must be guaranteed when the web application is split. is a serious challenge.

In the prior art, the parsing of Web applications is a closed process, and users cannot interfere with the parsing process of Web applications. On the one hand, this helps to ensure the security of network access, but on the other hand, it also limits the user's access to Web applications. Deep use.

After dismantling the web application, in some cases, it is necessary to select some code fragments from the dismantling results according to the user's needs to reassemble into a new web application (such as the previous weather on different web pages mentioned above) conditions and traffic flow conditions integrated into one web page), this process is also known as reloading. Reloading can generate new web applications expected by users according to existing web pages, and has broad prospects in practical applications.

Fig. 3 is a schematic diagram of how to split and reinstall an existing web application in an example.

Detailed ways

The present invention will be further described now in conjunction with accompanying drawing.

With reference to Fig. 1, the method for splitting Web application of the present invention comprises:

Step 101), obtaining the source code of the web application to be split from the web application server according to the user's request.

In this step, the web application to be split may include one or more web pages.

Step 102), obtaining split object information of the web application to be split.

The split object information of the web application to be split is used to describe which part of the code fragment needs to be split from the web application to be split, including one or more of the information such as the name, location, type, and length of the code fragment. There are many kinds, and it can also be other parameters that can determine a certain code segment. Wherein, the type of the code fragment includes at least a JavaScript fragment, an HTML fragment, and a CSS fragment, etc.; The number of starting or ending lines in a web page. The split object information may include content for multiple code fragments.

The split object information can be set by the user in real time, or can be preset and stored, and called in real time when the web application needs to be split.

Step 103), determine whether the source code of the web application to be split obtained in step 101) has been interpreted and executed, if so, end the split operation of the web application to be split, otherwise, the source code of the web application to be split obtained in step 101) Extract a piece of code that has not been interpreted and executed from the source code of the web application, and then execute the next step;

Step 104), check whether the extracted code fragments that have not yet been interpreted and executed contain the code fragments corresponding to the split object information obtained in step 102), if yes, execute the next step, otherwise re-execute step 103).

Step 105), interpreting and executing the extracted code fragment corresponding to the split object information that has not been interpreted and executed. Wherein, the interpreted execution includes: creating a control point label for the code fragment to be interpreted and executed; creating an independent workspace and an independent cache for the code fragment to be interpreted and executed, and storing the code fragment in the independent cache during the interpreted execution Intermediate states, intermediate parameters, and intermediate results generated during the process.

The control point tag is used to describe the operation to be completed by the control point corresponding to the code fragment during the interpretation and execution process. For example, in one embodiment, component B in the original web application A needs to be split and reinstalled in another new web application C. At this point, the control command to intercept the original web application A can be written in the control point tag (under the control of this control command, the entire code of the original web application A will no longer be interpreted and executed), and point to a certain working directory The commands related to generating the new web application C are stored in the working directory.

In this application, an independent workspace and an independent cache correspond to a specific code segment. In the independent workspace, the interpretation and execution of the corresponding code segment is realized by calling the corresponding executor. For example, a JavaScript engine may be invoked to interpret and execute the fragment for a JavaScript fragment, an HTML parser may be invoked for an HTML fragment to interpret and execute the fragment, and a CSS parser may be invoked for a CSS fragment to interpret and execute the fragment. Of course, in some cases, the code fragment to be interpreted and executed contains more than one type of code, such as a code fragment to be interpreted and executed contains HTML fragments and JavaScript fragments at the same time. There are labels separated, so it is easy to distinguish these codes and call the corresponding executor when interpreting and executing. During the execution of the above explanation, a series of intermediate states, intermediate parameters, and intermediate results will be generated, and these data will be stored in the independent cache corresponding to the code fragment. The independent cache is global, and the stored data can be accessed by other objects.

Those skilled in the art know that there may be a certain logical structure between different code fragments in a Web application, such as a call to another function in a JavaScript fragment, or a call from a parent page to a child page. The storage of the intermediate state, intermediate parameters, and intermediate results generated by the independent cache in the interpretation and execution of code fragments can preserve the logical relationship between different code fragments without spending a lot of resources to pay attention to the logical structure of the entire Web application.

Step 106), interpreting the control point tags obtained during the execution process and the intermediate state, intermediate parameters, and intermediate results stored in the independent cache as split results, and then re-executing step 103).

The above is a description of the basic implementation steps of the method for splitting a Web application in an embodiment of the present invention. In other embodiments, the method of the present invention may further include other steps.

In another embodiment, some web applications to be split require the user to perform login authentication. For example, for a certain mail system, the user needs to input an account number and password to enter the mail system. For this type of web application, when the method of the present invention splits, it is necessary to perform simulated login authentication according to the login authentication method of the web application before step 101). There are generally two login authentication methods for web pages: form login authentication and ntlm login authentication. How to simulate these two login authentication methods is well known to those skilled in the art, and will not be described in detail in this application.

In yet another embodiment, after step 101), the following step is further included: creating an independent workspace and an independent cache for the web application to be split. The independent workspace is used to interpret and execute the entire web application to be split or code fragments in the web application to be split, and the independent cache is used to save the intermediate state and intermediate state of a certain code fragment in the web application to be split. Parameters, intermediate results. In the subsequent reloading method or other application occasions, if the interpretation and execution of the code fragment is completed, the corresponding intermediate state, intermediate parameters, and intermediate results obtained can also be stored in the cache, and then can be returned to the waiting Split the server to which the web application belongs.

The order of the operation of searching for the split object information in the code fragment in the method of the present invention is not limited to the description in the foregoing embodiment. In another embodiment, after the code fragment is interpreted and executed, the code fragment can be interpreted and executed Find the split object information in the result, and then obtain the split result; in this embodiment, the split object information should describe the information after the code segment to be split is interpreted and executed.

The following JavaScript fragment is a part of the source code of a web application (the number at the beginning of each line indicates the number of lines of the line of code in the web application), taking this JavaScript fragment as an example, how to extract the fragment Exemplary instructions:

The split object information contains the content of splitting the runSum function in the above JavaScript fragment, for example, the split object information indicates that the name of the code fragment to be split is runSum, and the type is JavaScript fragment. Then in the process of loading code fragments, when a certain code fragment is found between the <script> and </script> tags and the name of the code is runSum, you can create a control point tag for this code fragment and assign an independent Workspace and independent cache, and then perform interpretation and execution, so as to achieve the purpose of splitting this code fragment from the original web application. In the split object information, the code segment to be split may also be described in other ways, such as the line characteristics of the start and end codes, or the line adjacent characteristics of the start and end codes. For example, for the runSum function in the aforementioned JavaScript fragment, the code fragment of the function can also be located and split according to the text feature "function runSum(){" in the start code and the text feature "}" in the end code.

Through the above operations, the method of the present invention can split one or more code fragments from a web application, and can also split multiple code fragments from different web applications. The code fragment may be a single type of code fragment, such as a code fragment obtained after a split containing only an independent JavaScript fragment, or a combination of different types of code fragments, such as a split The resulting code fragments include not only JavaScript fragments, HTML fragments, but also CSS fragments.

The technical scheme of the present invention can not only completely and correctly split the complex code fragments in the Web application, but also reinstall the split code fragments as required, and ensure that the split code fragments are can still be executed correctly. The method of reinstalling the web application requires the split result obtained by splitting the web application above. With reference to Fig. 2, the method for reloading Web application of the present invention comprises:

Step 201), determining the content and layout of the web application to be reinstalled;

In this step, how to determine the content and layout of the web application to be reinstalled can be realized through corresponding control commands. The control command markup language describes the page layout of the Web application to be reloaded, and determines the content of the Web application to be reloaded by calling the control point tags and the data in the independent cache.

In this step, the layout of the web application to be reloaded may be a layout redefined by the user.

Step 202), selecting the corresponding code fragment according to the content of the web application to be reinstalled;

Step 203), load the code fragment selected in step 202), obtain the split result of the web application where the code fragment is located based on the method for splitting the web application, and determine what to be completed according to the control point label of the code fragment The operation of reading a series of intermediate states, intermediate parameters and intermediate results generated during the interpretation and execution of the code fragment from the independent cache corresponding to the code fragment;

Step 204), according to the layout of the web application to be reinstalled determined in step 201), combine the required state, parameters, and intermediate results of the web application to be reinstalled with the intermediate state of the code fragment selected in step 202), The intermediate parameters and intermediate results are in one-to-one correspondence, and the next step is executed after the correspondence is successful;

Step 205), arranging the interpretation and execution results of each code segment to a specified location in the web application to be reinstalled, and generating a reinstalled web application.

The above is a description of the basic steps of the method for reinstalling a Web application in an embodiment of the present invention, and these steps realize the reinstallation of the Web application on the client side.

In another embodiment, it also includes the step of realizing the reinstallation of the Web application on the Web application server side. This step is located after step 203), including: returning a series of intermediate states, intermediate parameters, and intermediate results generated during the interpretation and execution of the selected code fragments to the cache of the Web application to be split, in the workspace Reassemble together with the interpretation and execution results of other code fragments of the to-be-split Web application, and return the obtained final result to the Web application server to which the to-be-split Web application belongs.

For ease of understanding, an example is given to illustrate the reinstallation of the above-mentioned web application on the web application server side. Assuming that three functions can be realized in a Web application 10, these three functions are respectively marked as 10A, 10B and 10C. The Web application 10 is disassembled, the code fragments corresponding to the function 10A, the function 10B, and the function 10C are separated, and then reinstalled into the Web application 20 , the Web application 30 , and the Web application 40 respectively. At this time, the user can see the Web application 20 with the function 10A, the Web application 30 with the function 10B, and the Web application 40 with the function 10C respectively through the client browser, and can realize corresponding functions through these Web applications , For example, function 10A is: realize the calculation operation of data through a calculator and save the calculation result in the database. But as far as the web application server is concerned, it only knows that there are web applications 10 , but it does not know that there are web applications 20 , 30 , and 40 . In order to maintain the accuracy of data synchronization and execution results, it is necessary to return the results of the functions implemented in the new Web applications 20, 30, 40 to the Web application server where the original Web application 10 of the function is located. The execution results of the applications 20, 30, 40 are returned to the Web application server to which the Web application 10 belongs. Therefore, the aforementioned reinstallation operation needs to be performed on the web application server side.

The above is a description of the execution steps of the method for splitting and reinstalling a Web application according to the present invention. For ease of understanding, this process will be further described below in conjunction with a specific example.

In the example shown in FIG. 3 , there are two web applications, which are marked as helloworldA page and helloworldB page respectively. Among them, the helloworldA page has three lines of labels, which are respectively represented as A1 line, A2 line and A3 line, and these three lines of labels are respectively used to perform the addition operation; the helloworldB page also has three lines of labels, which are respectively represented as B1 line, B2 line and B3 line, These three rows of labels are also used to perform addition operations, respectively. In this example, the user requests to aggregate the A2 line in the helloworldA page and the B3 line in the helloworldB page to a new page helloworldAB.

In order to meet the above requirements of the user, firstly, the helloworldA page and the helloworldB page need to be split respectively.

Take the splitting of the helloworldA page as an example. First obtain the source code of the page from the server; then extract the function named ABSum2 from the Script script of the source code of the page according to the needs of the user, the function of this function is to combine the value of the first element in row A2 with The value of the second element is added, and the A2 line tag HTML information is extracted from the HTML fragment of the page's source code. The splitting of the helloworldB page is similar.

After completing the above split operation, you need to reload to generate a new page helloworldAB. According to Figure 3, the content and layout that should be included in the new page helloworldAB are known, so in the reloading process, first execute the ABSum2 function by calling the JavaScript engine, and interpret and execute the HTML information of the A2 line label; then execute it by calling the JavaScript engine The ABSumB3 function (this function is used to add the value of the first element in the B3 line to the value of the second element in the Script script of the helloworldB page source code), and interpret and execute the label HTML information of the B3 line , and finally reload to generate a new page helloworldAB.

It can be seen from the examples above that the method of the present invention can split one or more original web pages, and then reinstall the content in one or more original web applications into a new web application required by the user according to the user's wishes. This is conducive to the further utilization of existing information on the network and better meet the needs of users.

In addition, the method of the present invention interferes with the generation process of the Web application through a series of operations such as splitting, parsing, and reinstallation. Compared with the original closed process, through the method of the present invention, the user can make the generation of the Web application The process is realized according to the route expected by the user, so as to achieve the result expected by the user.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than limit them. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent replacements to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and all of them should be included in the scope of the present invention. within the scope of the claims.
