搭建node.js服务器//引入express
const express = require("express");
//引入path
const path = require("path");
//创建一个express的application对象
const app = express();
//首先引入ejs
const ejs = require("ejs");
//通知express使用ejs模板引擎
app.set("view engine", "ejs");
app.set("views", "views");
app.get("/", (req, res) => {
//获取模板的路径
const filePath = path.resolve(__dirname, "index.ejs");
const data = "hello jingjing";
res.render(filePath, {
data: data,
name: "laowang",
user: [{
name: "laowang",
age: 18,
sex: "nan"
}, {
name: "xiaowang",
age: 19,
sex: "nv"
}, {
name: "zhongwang",
age: 28,
sex: "nan"
}, {
name: "dawang",
age: 38,
sex: "nv"
}]
})
})
//监听端口号和服务器状态
let port = "3002";
app.listen(port, err => {
if (err) {
console.log(err);
return;
}
console.log("服务器启动，请访问" + ` http://127.0.0.1:${port}`);
})
