Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
IDE is an Integrated Development Environment (Integrated Development Environment) abbreviation. The IDE is a piece of programming software, an application software that integrates some of the basic tools, basic environments, and other ancillary functions that would be required in the development of a programmer's language. An IDE generally contains several main components: code Editor (Editor), Compiler, Interpreter (Compiler, Interpreter), and Debugger (Debugger). Developers can access these components through a Graphical User Interface (GUI) and implement the entire code compilation, debugging, and execution process. Present IDEs also provide some high-level auxiliary functions that help programmers provide development efficiency, such as code highlighting, code completion and prompting, syntax error prompting, function tracing, breakpoint debugging, etc.
The integrated development environment is software for editing code, and each door language has its own integrated development environment. Each language corresponds to multiple programming development environments IDE, and different programming developers prefer different integrated development environments. Existing or reasonable, and every existing integrated development environment in the market has unique charm. In the field of mobile banking channels, due to the characteristics of diversity, safety, short development period, complex authority management, variable terminal services and the like of service requirements, a general language on the market cannot well solve the problem, and a language and a corresponding application framework need to be independently developed to solve the requirements.
Under the existing technical conditions, the general IDE on the market cannot identify the independent language and grammar developed in the field of bank mobile financial channels, and cannot meet the functional requirements of highlighting the code of the independent language, completing and prompting the code, prompting grammar error, tracing functions, debugging breakpoints and the like. In the development process of a developer, functions such as identity authentication, authority identification, authority management and the like need to be performed through some interfaces provided by a bank, and a general IDE in the market cannot perform one-to-one docking with the bank.
In the business developed based on the bank mobile financial channel, the normal development process is as follows: after receiving the requirements, the developer performs the work of service development, deployment, testing and the like on the development language, development framework and development environment specified by the line side. However, in the face of management problems generated by a huge developer group and requirements of the financial industry on the safety of business data and the like, the expert is urgently required to perform authority management, user authentication, transaction interface management and the like on the developed personnel, and the conventional general IDE on the market cannot meet the requirements. And because the user-defined development language, grammar and semantics are used, the general IDE in the market cannot well support the specific functional requirements of code prompt, high grammar brightness, real machine debugging and the like.
Therefore, how to provide a customized IDE for a developer in a service development process to solve the functional requirements of syntax and semantic analysis, syntax highlighting, code prompting, etc. for a specific development language, develop a corresponding functional interface aiming at the requirements of authority management, user authentication, etc., and use the developed customized IDE for application development is a technical problem to be solved by the present invention.
Fig. 1 is a schematic diagram of the main steps of a method of application development according to an embodiment of the present invention. As shown in fig. 1, the method for application development according to the embodiment of the present invention mainly includes the following steps S101 to S103.
Step S101: writing a source code file by using a self-defined code writing language;
step S102: performing syntax semantic analysis on the source code file to obtain a structured syntax tree;
step S103: and prompting codes according to the structured syntax tree and a preset label file, and carrying out application development by using a self-defined code writing language.
FIG. 2 is a diagram illustrating a parsing process according to an embodiment of the present invention. As shown in fig. 2, when the code editor edits and saves the code, the user starts a syntax parser of the code, the source code performs syntax semantic analysis through ANTLR, and then outputs a specified structured syntax tree, and the output structured syntax tree is subsequently used for code prompting, so that the syntax parser is added to the code prompting processor to perform the next code prompting processing.
According to an embodiment of the present invention, the process of performing code prompting according to the structured syntax tree and the preset tag file may mainly include: judging whether a label needs to be edited or not according to the structured syntax tree and the current input character; if so, acquiring the label type from a preset label file; and assembling the related label data structures into a data structure required by a prompt box to display according to the label type, and displaying through the prompt box to prompt a code.
Wherein, the current input character is obtained by the following method: adding a keyboard monitoring event in the code editing part; and when the monitored event is a key event, acquiring the current input character from the information of the key event.
In an embodiment of the present invention, the tag types include, for example, component tags, attribute tags, and attribute value tags.
Fig. 3 is a schematic code prompting flow diagram according to an embodiment of the present invention. As shown in fig. 3, first, a configuration file of the custom tag is read, and an example of the file configuration is, for example:
{
1,// component ID
"View",// tag name such as: < view > < view >, < switch >, etc
"relatettrsids" [1,2,3],// associated attribute tag ID
"nodeType":3,
"subTagIds":[]
}。
And reading a series of configuration files, constructing a cache data structure of the custom tag, and adding a keyboard monitoring event to the code editor. And when the user triggers the key event, the event processing is carried out, the source of the event triggering is judged, and whether the label needs to be edited or not is judged by combining the structured syntax tree and the current input character obtained from the key event. Specifically, if the trigger position of the key event meets the specification of the component tag, the data structure of the associated component tag is assembled into a data structure required by a code prompt box to display, the code is converted into a group, and the group is displayed through the prompt box to prompt the code. Among them, the specification of the component tag is, for example: and judging which part is in the range of [ < view class [ < bigLable > ] </view > ], wherein the view is a label name, the class is a label attribute, and the bigLable is a label attribute value according to the cursor position when the key event is triggered currently.
FIG. 4 is a diagram illustrating the effect of code hinting on component tags, according to an embodiment of the present invention. For example: when the keyboard of the user inputs '<' symbol, the editing of the component label is considered to be triggered, so that the corresponding label prompt is carried out on the code of the component label.
Fig. 5 is a schematic diagram of a code hint effect of an attribute tag according to another embodiment of the present invention. Fig. 6 is a schematic diagram illustrating a code hint effect of an attribute value tag according to yet another embodiment of the present invention. As can be seen from fig. 5 and 6, the cursor position at the time of code prompting of the trigger attribute tag and the trigger attribute value tag is different, that is, the current input position is different.
According to another embodiment of the present invention, after the application development is completed, the code of the application may be uploaded to a server, and the uploading process includes: compiling codes, packaging resources and uploading resources. In the prior art, the deployment of the application is generally realized by directly performing offline update on the developed application code by a server. The micro application developed by the invention does not need off-line updating.
After the code of the micro-application is written through the IDE, the micro-application item can be uploaded to the server, and the effect can be previewed on the real machine. The whole uploading process is mainly divided into 3 steps: compiling codes, packaging resources and uploading the resources to a server. And if the 3 steps are successfully executed, the micro application project is uploaded to the server, otherwise, a certain step is wrong or fails, the micro application project is not executed downwards, and the user is prompted as to which step is wrong and the reason of the failure.
Fig. 7 is a schematic diagram of a code uploading process according to an embodiment of the present invention. As shown in fig. 7, the code uploading process of the embodiment of the present invention mainly includes:
(1) compiling code
And calling a compiling command by using java, lang, Runtime, simultaneously monitoring a stream output during compiling, and using a regular matching mark of compiling failure and a mark of compiling success. If the compiling fails, the next execution is not performed, and error information and failure reasons are returned. If the compiling is successful, other steps are continued downwards. The compiling process supports the active interruption of a user, and the compiling process cannot be continuously executed downwards after interruption, so that the whole uploading process is finished;
(2) packaging resources
And packaging and compressing the directory where the code compiled in the last step is located, and using an org. If abnormity occurs during the packing compression, the down execution is not performed any more, and the abnormity information is returned. If the packing compression is successful, continuing to execute the next step;
(3) resource uploading
And sending a post request to the server by using the zip resource package and item information (comprising an AppID, an item remark, version information and the like) by using the httpclient. If the server returns the message of login overtime, the IDE will help the user to automatically log in, if the automatic login is overdue, the IDE will pop up the login window to let the user log in manually, and the user will continue to upload after the login is successful, otherwise, the IDE will cancel the upload. If the server returns a message exceeding the uploading size limit of the resource package, the user needs to be prompted to successfully upload the message after adjusting the size of the project. If the server returns the information that the AppID does not exist, the user needs to be prompted to check the filled AppID. If the uploading time is over due to network reasons, the user can click the re-uploading button, the resource packet can be re-uploaded to the server, and the two previous steps (compiling the project and packaging and compressing) are not required to be re-executed, so that the time of the user for re-waiting for uploading is greatly saved. And if the uploading of the resource packet is finished and no abnormal information is returned, prompting the user that the uploading is successful. And the uploading resource packet supports the active interruption of the user to the server, and the uploading is stopped after the interruption.
According to an embodiment of the present invention, after the micro application code is successfully uploaded, the following steps may be further performed: and generating a two-dimensional code, and downloading the application by scanning the two-dimensional code by the terminal equipment to perform real machine test.
Fig. 8 is a schematic diagram illustrating an implementation effect of generating a two-dimensional code according to an embodiment of the present invention. As shown in fig. 8, after the micro application code is uploaded through the IDE, a two-dimensional code as shown in the figure may also be generated, so that the terminal device may download the application by scanning the two-dimensional code, thereby facilitating the implementation of the real machine test.
According to the embodiment of the invention, before uploading the code of the application to the server, the label in the code of the application can be detected, and the specific process comprises the following steps: acquiring all tags in a page and judging whether a designated tag exists; and if so, generating prompt content aiming at the specified label.
In combination with the application scenario of the embodiment of the invention, for applications in the field of mobile finance, different banks can develop different applications, so that the micro applications can be divided into inline applications and non-inline applications. And when the tags of the pages are limited to be used, the uploading is stopped and the user is prompted which tag of the pages needs to be modified until the tags limited to be used are modified to the application tags in the row, and then the uploading can be continued. Generally, the IDE program has a configuration file inside to support configuring the in-line application specific tags, and all in-line application tags are configured in the configuration file.
FIG. 9 is a schematic diagram of a tag detection flow according to an embodiment of the present invention. As shown in fig. 9, the label detection process mainly includes the following steps:
(1) reading in-line labels
Reading the content of the in-line label configuration file, and storing the in-line labels in the Set. Meanwhile, the part of the tag from the specified beginning is intercepted as the tag for limiting use, and the tag for limiting use is stored in another Set.
(2) Traversing content of a page, matching tags
Json file, and traversing all page files of the pages. The content of each pagefile is read, and each line of the content is traversed. First, determine if the line is annotated, then not check the tag in the line, specifically, if the line is <! If the line is annotated, the next line is continuously traversed without performing label matching operation downwards; if the column is just <! The beginning does not end with- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -. If the line is not the annotated line, obtaining the label of the line by using regular matching, wherein the regular matching uses the Pattern class and the Matcher class under the java. After all the rows of the page file are traversed, the path of the page file is used as a key, and the set A of the tags which are stored and limited to be used is used as a value to be stored in the Map. And finally, judging whether the size () of the Map storing the limited use label is larger than 0, if so, traversing the Map storing the limited use label, and constructing the prompt content using the limited use label so as to guide the user to modify which label on which page.
According to another embodiment of the invention, in the application development process of the invention, a simulator can be embedded in the integrated development environment to perform functional simulation on the source code file. Therefore, the code is convenient to edit, modify and debug, and the application development efficiency is improved.
FIG. 10 is a diagram of a master interface layout for an integrated development environment, in accordance with an embodiment of the present invention. IDE is used as a development tool and is also graphical interface software, many functions need to develop a functional interface, if a set of graphical interface library is re-developed, the problems of high cost, long development period, unstable performance and the like undoubtedly occur, and a compromise scheme is to use a set of mature graphical interface scheme and perform customized development on the basis.
In the embodiment of the invention, the IDE selects Eclipse RCP as a graphic development library, and the interface is customized and developed on the basis. The Eclipse RCP is a function located in the core of an Eclipse platform, provides a standardized component model, comprises menus, toolbars and the like, provides rich interface controls, and enables desktop applications to be developed on the basis of Java easily.
In the layout diagram of the main interface of the IDE shown in fig. 10, the simulator and the debugging panel are open source browser groups CEF (Embedded Framework), and other interface parts are RCP (rich client Platform), SWT (Standard Widget Toolkit) components which are customized and developed according to requirements.
As shown in fig. 10, the left side is a simulator, a developer can edit codes on the right code editor and preview the effect of code functions in real time through the left simulator, and the left simulator is a Chromium Embedded Frame (CEF), which is an open-source Web browser control based on the Google Chromium project, supports Windows, Linux, and Mac platform, and provides a Java interface.
In the current development process of mobile financial services, a plurality of service scenes need to acquire user information of a current login mobile phone or open a camera to take a picture and acquire information such as geographic position, so that development and updating maintenance cost is reduced as much as possible, codes written by a front end can be developed and run at multiple ends at one time, the principle is developed, JavaScript plays a very important role, the JavaScript plays a role in bridging with other technologies, any mobile operating system comprises a container capable of running JavaScript, such as WebView and JSCore, and when the JavaScript is run without running other languages, a running environment needs to be additionally added. JSBridge is just such a bridge, which provides JavaScript with the ability to call Native, which can also manipulate JavaScript. Therefore, the front end part can conveniently use Native capabilities (Native functions) such as geographic positions, cameras and login payment. The JSbridge constructs a channel for message communication between the Native function Native and the non-Native function Native, and is a channel for two-way communication. Thus, in embodiments of the present invention, a bi-directional communication channel of messages between native functions and non-native functions is constructed based on an integrated development environment to enable communication between a source code file and a simulator.
The simulator acts as a mobile phone client, and provides the implementation of a Native interface in a front-end framework for a developer, for example, the developer needs to obtain user information of a current login user, or invokes the front-end framework to initiate a network request, and the like, and JSBridge in the IDE is a bridge for communication between a self-defined code writing language (e.g., H5) and a local function Native, and is used for implementing two-way communication between an H5 page and the Native. To realize the communication between the H5 page and Native, the following three problems are solved:
1. how JavaScript calls Java;
2. method parameters and how callbacks are handled;
3. what is the data format of the communication.
According to the embodiment of the invention, the communication process between the source code file and the simulator comprises the following steps: writing a page style through a source code file to determine a layout of components on a page; responding to the triggering behavior of the page, and constructing a communication channel between the source code file and the simulator; registering and responding to monitoring at an integrated development environment end to call a native function through a simulator; and dynamically calling the specified method through a reflection mechanism according to the class name and the method name in the communication protocol, and returning the result to the page after the native function executes the specified method.
FIG. 11 is a diagram illustrating a communication process between a page and a simulator implemented by a source code file according to an embodiment of the present invention. As shown in fig. 11, the communication process between the page and the simulator implemented by the source code file according to the embodiment of the present invention is mainly as follows:
1. writing a page style through a source code file to determine a layout of components on a page;
2. the JS writing trigger behavior corresponding to the page calls a front-end framework API, and corresponding codes of the JS writing trigger behavior are as follows:
the code simulating calling of front end framework API from the mobile phone terminal and initiating transaction through JSbridge
The front-end framework calls JSBridge as follows:
JSBridgePlugin JS bridge component
const JSBridgePlugin＝{
// CEF interface to browser calls (CEF component calls IDE)
cefQuery:function(success,error,requestJsonObj){
try{
V/interface conversion to string
var jsonStr＝JSON.stringify(requestJsonObj)；
Log ('JSBridgePlugin- -the json string of the request \ r \ n' + jsonStr);
JsBridgeRouter provides a JS bridge counterpart to CEF
V/initiate a network transaction by the query method in the jsBridgeRouter object and return the result to responseStrer
var responseStr＝jsBridgeRouter.query(jsonStr)；
// string to JSON object
var responseJson＝JSON.parse(responseStr)；
//console.log("result:"+JSON.stringify(responseJson.result))；
V/callback front end frame success or failure interface according to status code
var result＝responseJson.result；
var isSuccess＝responseJson.isSuccess；
var statusCode＝responseJson.statusCode；
// callback success interface
if(isSuccess){
success(result)；
}else{
// callback failure interface
var jsonObj＝{}；
jsonObj.error＝result；
jsonObj.code＝statusCode；
error(jsonObj)；
}。
In this embodiment, JSBridge only provides a method for transferring character strings, and the communication protocol structure needs negotiation definition between the H5 end and the Native end, so the structure of the data communication protocol is defined as follows:
{
// class of methods requiring invocation
className:"AAANetwork",
Method name of// class
methodName:"request",
Method type parameters and incoming data
jsonnData: { data: "custom data body" }
}；
3. And registering and monitoring at the IDE end and responding to the monitoring. For example: adding monitoring by using a method CefBrowserclient. addMessageRouter, owning callback of JS file by using an onQuery method, and calling a Native method in the callback method;
4. acquiring a class name and a method name in a communication protocol;
5. dynamically calling all implementation class methods exposed to the front end through a Java reflection mechanism;
6. calling back the Java corresponding class of the callback method in the JavaScript, and after the Native executes the implementation class method in the step 5, returning result data to a front end H5 page through CefBrowserclient.
