Description
Technical field
The present invention relates to web development technologies field, particularly a kind of Quick Response Code generated according to URL addresses is embedded into figure
The method of piece.
Background technology
The Quick Response Code of special disposal generation at present is embedded into function on the line on picture and compares shortage；Much all simply generate two
Code is tieed up, can not be embedded in the function of original picture；Had a greatly reduced quality on the usage degree for meet user.
The content of the invention
Present invention solves the technical problem that it is to provide a kind of side for being embedded into picture according to URL addresses generation Quick Response Code
Method；Help to provide the help and reference that picture function is handled on line, greatly reduce the operating time that user handles picture, save
The step of installing special disposal picture software instrument.
The present invention solve above-mentioned technical problem technical scheme be：
Under node.js environment, installation qr-image module applications generate two-dimension code image in generation Quick Response Code, editor
Method；Images module applications are installed in processing picture, the method for editing embedded Quick Response Code；Foregoing 2 methods are encapsulated to arrive
util.js；Then asynchronous process control module async is installed, combine foregoing 2 methods to async；It is packaged to perform async
Flow path processing method, export the picture of embedded Quick Response Code.
Call qr-image intermediate controls, configuration variables parameter url, picture format, size and callback call back functions；
Combined by the use of date plus random number as picture name, picture name be nested on fs.createWriteStream functions,
Daily record plus abnormal conditions is exported, the method for completing generation Quick Response Code, then method is encapsulated in inside utils { }.
Call images storehouses, configuration variables parameter original picture path, two-dimension code image path callback call back functions；Adjust
With the size of .size () method configuration picture .draw () configurations two-dimension code image is called to be embedded into the position in original picture
Put, call .save () method to preserve picture to file, complete the method for embedded Quick Response Code, then method is encapsulated in
Inside utils { }.
Utils files and async control are quoted on js files, has configured the parameter in the method for Quick Response Code generation,
Url addresses are added, are packaged into task1 variable methods, the path of original picture is configured to being embedded in the parameter of Quick Response Code, is packaged into
Task2 variable methods, finally in calling two methods of async.waterfall combination of function task1 and task2 to operation flow
Carry out step-by-step processing, generate Quick Response Code method (task1) put before, the method (task2) of embedded Quick Response Code adds behind putting
The daily record output of abnormal conditions, completes whole asynchronous flow control method.
The packaged flow path processing methods of async are performed, result exports the picture path after embedded Quick Response Code, opens text
Part folder realizes preview picture effect.
The generation Quick Response Code module qr-image that the present invention is provided using nodejs core tool, embedded picture watermark mould
Block images and asynchronous process control module async.The implementation process of overall procedure, which helps to provide on line, handles picture function
Help and reference, greatly reduce user handle picture operating time, save installation special disposal picture software instrument step
Suddenly.Inventive method of the present invention helps to provide the operation of more preferable processing picture and valuable referential on platform line, it is not necessary to
The processing of background java code, it is only necessary to realized in page front end, processing logic is fairly simple, understandable, and favorable expandability, energy
It is transformed into batch processing or freely pulls the position of two-dimension code image.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is the flow chart of the present invention；
Fig. 2 is present invention generation Quick Response Code method and embedded picture approach code sectional drawing；
Fig. 3 is the execution method code sectional drawing of Row control combination of the present invention.
Embodiment
Below in conjunction with accompanying drawing, clear, complete description is carried out to the technical scheme in the embodiment of the present invention, it is clear that institute
The embodiment of description is only part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention,
Those of ordinary skill in the art are not making the substantive scheme created and obtained, and belong to the scope of protection of the invention.
As Fig. 1, specific implementation step of the invention are as follows：
1st, nodejs instruments are downloaded, are installed on local development environment.Detect whether that success has been installed after installation, under double-click
The installation kit Node.exe of load, meeting eject command row window, is inputted on window：Cd node installation directory address, then it is defeated
Enter:-- version, window can export node version number, prove that node has installed success this moment.
The 2nd, qr-image modules are installed, this module is mainly used in generation Quick Response Code, and npm is inputted in command window
Install qr-image, installed successfully after execution.
3rd, the method for editor's generation two-dimension code image, calls qr-image intermediate controls, configuration variables parameter url, picture
Form, size and callback call back functions.By the use of date plus random number combination as picture name, picture name is nested into
On fs.createWriteStream functions, the daily record plus abnormal conditions exports, and the method for whole generation Quick Response Code is substantially complete
Into, then method is encapsulated in inside utils { }.
The 4th, images modules are installed, the method that this module is mainly used in processing picture synthesising picture is defeated in command window
Enter npm install images, installed successfully after execution.
5th, the method for editing embedded Quick Response Code, calls images storehouses, configuration variables parameter original picture path, two-dimension code image
Path callback call back functions.The size of the .size () method of calling configuration picture, call .draw () configuration Quick Response Codes
Picture is embedded into the position in original picture, calls .save () method to preserve picture and is entirely embedded in Quick Response Code on file
Method is basically completed, then method is encapsulated in inside utils { }.
The 6th, asynchronous process control module async is installed, this module application is in combination producing Quick Response Code and embedded Quick Response Code
The control of two method flows, npm install async are inputted in command window, are installed successfully after execution.
7th, asynchronous flow control method is edited, utils files and async control, configuration two are quoted on js files
The parameter in the method for code generation is tieed up, url addresses is added, is packaged into task1 variable methods, configures the path of original picture to being embedded in
In the parameter of Quick Response Code, be packaged into task2 variable methods, finally call async.waterfall combination of function task1 and
Two methods of task2 to step-by-step processing is carried out in operation flow, generate Quick Response Code method (task1) put before, embedded two dimension
Behind the method (task2) of code is put, the daily record plus abnormal conditions exports, and whole flow process control method just finishes.
8th, the packaged flow path processing methods of async are performed, result exports the picture path after embedded Quick Response Code, opened
File can preview picture effect.
Present invention generation Quick Response Code method and embedded picture approach, the code sectional drawing of the execution method of control combination are shown in respectively
Shown in Fig. 2, Fig. 3.
