ajax 与 node 的前后台交互

服务端：

const http = require("http");
const fs = require("fs");
const url = require("url");
const querystring = require("querystring");


let data = '成功开启服务';
fs.writeFile('文件.txt', data, 'utf8',(err) => {
    if (err) throw err;
    console.log('日志已经输出');
});

let server = http.createServer(function (req,res) {

    let arr = req.url.toString().split('/');
    let arr1 = __dirname.toString().split('\\');
    const UrlArr = arr1.join('/');

    if(req.url === '/') {
        console.log(2);
        fs.readFile('./server.html', (err, data) => {
            res.setHeader("Access-Control-Allow-Origin","*");
            res.writeHead(200, {
                'Content-Type': 'text/html'
            });
            res.write(data,'utf8');
            res.end();
        })
    }
    else if(arr[1] === 'css'){
        fs.readFile(`${UrlArr}${req.url}`, (err, data) => {
            res.setHeader("Access-Control-Allow-Origin","*");
            res.writeHead(200, {
                'Content-Type': 'text/css'
            });
            res.write(data, 'utf8');
            res.end();
        })
    }
    else if (arr[1] === 'js'){
        fs.readFile(`${UrlArr}${req.url}`, (err, data) => {

            res.setHeader("Access-Control-Allow-Origin","*");
            res.writeHead(200, {
                'Content-Type': '*/*'
            });
            res.write(data, 'utf8');
            res.end();
        })
    }
    else if (arr[1] === 'images'){
        fs.readFile(`${UrlArr}${req.url}`, (err, data) => {
            res.setHeader("Access-Control-Allow-Origin","*");
            res.writeHead(200, {
                'Content-Type': 'image/*'
            });
            res.write(data);
            res.end("结束");
        })
    }


});

server.listen(8088,'127.0.0.1',()=>{
    console.log('服务器开始监听！');
});

客户端：

function reqListener () {
    console.log(this.responseText);
}

var oReq = new XMLHttpRequest();
console.log(1);
oReq.addEventListener("load", reqListener);
console.log(2);
oReq.open("GET", "http://127.0.0.1:8088/");
console.log(3);
oReq.send();
console.log(4);
