安装某些软件包
npm install
npm install mongoose --save
npm install express --save
npm install body-parser
Router.js文件
var Express = require("express");
var Routes = Express.Router();
var UserRoute = require('./src/User/User.Route');
var CommentRoute = require('./src/Comment/Comment.Route');
Routes.use('/user/', UserRoute);
Routes.use('/comment/', CommentRoute);
module.exports = Routes;
app.js
const Express = require("express");
const BodyParser = require("body-parser");
const Routes = require("./Routes");
const Cors = require("cors");
const app = Express();
app.use(Cors());
app.use(BodyParser.urlencoded({ extended: false }));
app.use(BodyParser.json());
app.use('/', Routes);
app.listen(8080, 'localhost', (err) => {
if(err) {
console.log(err);
process.exit(-1);
}
console.log("Server listen port 8080");
});
User.Route.js这是包含user.Route.js的文件
