Express 静态资源路由

express 路由

express 路由

主要通以下方法去进行去区分url，从而对不同模块进行分别请求处理

app.get('/', (req,res)=>{res.send()})
app.post('/', (req,res)=>{res.send()})
app.pust('/', (req,res)=>{res.send()})
app.delete('/', (req,res)=>{res.send()})

const express = require('express');
const app = express();

app.get('/', (req, res) => {
  res.send('hello world');// res.write + res.end
})

app.post('/', (req, res) => {
  res.write('post hello world');
  res.end()
})

app.put('/', (req, res) => {
  res.send('put hello world')
})

app.delete('/', (req, res) => {
  res.send('delete hello world')
})

app.listen(3000, () => {
  console.log('localhost start 3000 ...')
})

Express 静态资源文件路由

通过express.static(sourceUrl)指定静态资源目录
通过app.use()完成路由配置

express.static(url)是内置中间件，同为内置中间件的还有用于解析数据请求的bodyParder.json()

const express = require('express');
const path = require('path');
const app = express();

//配置多个静态资源目录
//访问：http://localhost:3000/loading.gif
app.use(express.static('public/images'));
// app.use(express.static('public/files'));

//配置多级目录
//访问：http://localhost:3000/static/1.png
app.use("/static",express.static('public/images'))

//配置绝对路径
//访问：http://localhost:3000/static/loading.gif
app.use('/static',express.static(path.resolve(__dirname,'public/files')));

app.listen(3000,()=>{
    console.log("server run at port 3000...");
});
