Use the Nodejs Express framework to build a server on this computer

Brief introduction

Use the express framework to build a server on this machine so that you can run the appropriate functionality on your server with the specified URL.

Express is a NODEJS-based framework that we can use to complete the service-side authoring.

The following Mocker file structure I have uploaded to GitHub.

Installation

First install Nodejs and NPM, these two things are a bit like Python and pip relationship, Nodejs is a JS package, and NPM can install some libraries for Nodejs.

With the Nodejs after installing Express.

Then create a local folder, as the node server is located in the folder, I named Mocker. Install click here to view tutorials.

After that, a static folder is created in the Mocker folder for use in the passive resource file.

Then create a scripts folder to put my Python script.

My idea is that the user accesses my server my local nodejs can invoke a Python script to accomplish some tasks and then present the results to the user.

My node script is called Mocker.js, which reads as follows:

functionSleep (sleeptime) { for(varStart = +NewDate; +NewDate-start <=sleeptime;) { } }functionExec_cmd (cmdstr) {varexec = require (' child_process '). exec; EXEC (CMDSTR,function(err,stdout,stderr) {if(Err) {Console.log (' Error: ' +stderr); } Else{console.log (stdout); }    });}varExpress = require (' Express ');varApp =Express ();varPath = require (' path '); Console.log (Path.join (__dirname,‘/‘) ; App.use (Express.static (Path.join (__dirname,‘/‘)));varDistribution = '/static/html/distribution.html 'App.get ("/distribution",function(req, res) {varcmdstr = ' python scripts/check_tasks_distribution.py ';    Exec_cmd (CMDSTR); varFS = require ("FS"); Fs.exists (Path.join (' Static ', ' HTML ', ' distribution.html '),function(exists) {if(exists) {res.redirect (distribution); } Else{exec_cmd (CMDSTR); Sleep (1000); }    });});varServer = App.listen (3000,function () {    varHost =server.address (). Address; varPort =server.address (). Port; Console.log (' Listening at http://%s:%s ', host, Port);});

The main idea is that when users access distribution this route will be on my server through the command line to execute the Scripts folder under the Check_tasks_ distribution.py the script and then opens the generated static resource file Distribution.html page. This script I used to write a statistical function about the Jira task that everyone in the statistics group is working on.

Start

Execute the command line under the Mocker path to start the Mocker.js server file:

You can then access the list of Jira tasks in progress in the browser via Http://server-ip:3000/distribution.

Inspired

We can integrate scripts that are usually written to help our daily work to this server, so that we can display the script and tools platform to colleagues for sharing purposes.
