Save the list of stations to the database and create the service locally
node. JS Create Httpserver
1. Build an express-based operating environment
Global Installation Express-gengerator
CNPM install-g Express-gengerator
2. Create an express project and create a local service
Express Server
Build the server directory, the bin under the directory is an executable file, run the www file under the bin to start the service
Node server/bin/www
Startup successfully opened browser localhost:3000
App.js under Server is a portal file
Configuration of the App.js
varCreateerror = require (' http-errors '));varExpress = require (' Express ');varPath = require (' path ');varCookieparser = require (' Cookie-parser '));varLogger = require (' Morgan ');varEjs = require (' Ejs '));varindex = require ('./routes/index '));varUsers = require ('./routes/users '));varStations = require ('./routes/stations '));varApp =Express ();//View engine SetupApp.set (' Views ', Path.join (__dirname), ' views ')); App.engine ('. html ', ejs.__express); App.set (' View engine ', ' HTML '); App.use (Logger (' Dev ') ; App.use (Express.json ()); App.use (express.urlencoded ({extended:false}); App.use (Cookieparser ()); App.use (express.static (Path.join,' Public ')) ; App.use (‘/‘, index); App.use ('/users ', users); App.use ('/stations ', stations);//catch 404 and forward to error handlerApp.use (function(req, res, next) {Next (Createerror (404));});//Error HandlerApp.use (function(Err, req, res, next) {//set locals, only providing error in developmentRes.locals.message =Err.message; Res.locals.error= Req.app.get (' env ') = = = ' Development '?err: {}; //render the error pageRes.status (Err.status | | 500); Res.render (' Error ');}); Module.exports= app;
Installing Mongoose
CNPM Install Mongoose--save
Add a stations.js file under the Routing route folder
varExpress = require (' Express ');varRouter =Express. Router ();varMongoose = require (' Mongoose '));varStations = require ('.. /models/stations ');//Link MongoDB DatabaseMongoose.connect (' Mongodb://127.0.0.1:27017/train '); Mongoose.connection.on ("Connected",function() {Console.log ("MongoDB connected success.");}); Mongoose.connection.on ("Error",function() {Console.log ("MongoDB connected fail.");}); Mongoose.connection.on ("Disconnected",function() {Console.log ("MongoDB connected disconnected.");}); Router.get ("/",function(req,res,next) {//res.send (' hello,goods list. ')Stations.find ({},function(err,doc) {if(Err) {Res.json ({status:' 1 ', msg:err.message}); }Else{Res.json ({status:' 0 ', msg:‘‘, result:{count:doc.length, List:doc} })}); module.exports= Router;
New models folder under Server folder, new Stations.js file under Models
var mongoose = require (' Mongoose '); var Schema = Mongoose. Schema; var New Schema ({ "Sta_name": String, "Sta_ename": String, "Sta_code" = Mongoose.model (' station ', Stationschema);
Finally, open the localhost:3000/stations to access the station data.
Can be loaded via interface access, Vue with Axios, but there will be a cross-domain problem, under the config file under the Vue project, index.js change Configuration
proxytable: { '/stations ': { target:' http://localhost:3000 '} },
After a series of configurations, you will be able to access the Axios through a pleasant interface.
