前端html代码：
<html>
<head>
<meta charset="UTF-8">
<title>AJAX 实例</title>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.js"></script>
<script>
var data="data=sdd&hf=jkhklh" // 要提交的数据
// 使用ajax提交get方式数据
function ajax(){
var oAjax = new XMLHttpRequest();
oAjax.onreadystatechange = function (){
if(oAjax.readyState == 4&& oAjax.status == 200){
alert(oAjax.responseText);
}
}
oAjax.open('GET', '/ss?'+data);
oAjax.send();
}
// 使用ajax提交post方式数据
function ajaxP(){
var oAjax = new XMLHttpRequest();
oAjax.onreadystatechange = function (){
if(oAjax.readyState == 4&& oAjax.status == 200){
alert(oAjax.responseText);
}
}
oAjax.open('POST', '/ss');
oAjax.send(data);
}
</script>
</head>
<body>
<button type="button" onclick="ajax()">Get</button>
<button type="button" onclick="ajaxP()">Post</button>
</body>
</html>
后端node.js代码：
var http = require("http");
var fs = require("fs");
var url=require("url");
var app=(req,res)=>{
var pathname = url.parse(req.url).pathname;
var method = req.method.toLowerCase();
if(pathname=="/favicon.ico")return;
if(pathname=="/"){
fs.readFile("./ajax.html",(err,data)=>{
res.writeHead(200,{'content-type':'text/html;charset=utf8'});
res.end(data);
})
}
if(pathname=="/ss"&&method=="get"){
// console.log(url.parse(req.url).query);
res.writeHead(200,{'content-type':'text/html;charset=utf8'});
res.end('{"data":"这是GET数据"}');
}
if(pathname=="/ss"&&method=="post"){
// console.log("sdsd");
req.on("data",function(data){
//打印
// console.log(decodeURIComponent(data));
});
res.writeHead(200,{'content-type':'text/html;charset=utf8'});
res.end('{"data":"这是POST的数据"}');
}
console.log(url.parse(req.url))
}
http.createServer(app).listen(8000);
