比如客户端页面点击按钮的onclick事件，下载http://192.168.3.123:7077/users的页面，以.html格式保存 http://192.168.3.123:7077/users的对应路由代码：
var express = require(‘express’); var router = express.Router();
/* GET users listing. /
router.get('/’, function(req, res) {
// res.send(‘respond with a resource123456’);
var Cookies = {};
req.headers.cookie && req.headers.cookie.split(‘;’).forEach(function( Cookie ) {
var parts = Cookie.split(‘=’);
Cookies[ parts[ 0 ].trim() ] = ( parts[ 1 ] || ‘’ ).trim();
});
console.log(Cookies);
res.writeHead(200, {’Content-Type’: 'text/html’});
res.write('<html>'+
'<head>'+
'<script type="text/javascript">'+
'function load(){’+
// 'alert(“start!”);’+
/ 'var url=location.search;’+
'var result=url.split(“=”)[1];’+
'if(result!=null){’+
'document.getElementById(“result”).value=result;’+
'}’+
*/
'alert(getCookie(“result”));’+
'document.getElementById(“result”).value=getCookie(“result”);’+
// 'alert(“end!”);’+
'}’+
'function getCookie(name){’+ //获取cookie
'if (document.cookie.length>0){’+
'c_start=document.cookie.indexOf(name + “=”);’+//查询cookie键名
'if (c_start!=-1){’+ //查询到cookie键名
'c_start=c_start + name.length+1;’+//查询到cookie键名
'c_end=document.cookie.indexOf(";",c_start);’+
'if (c_end==-1) c_end=document.cookie.length;’+//如果只有一个cookie键值对，该方法才有效；
'return unescape(document.cookie.substring(c_start,c_end));’+
'}’+
'}’+
'return "";’+
'}’+
'</script>'+
'</head>'+
'<body onload="load()">'+
'<input type="text" id="result" value=""/>
'+
'</body>'+
'</html>');
res.end();
});
module.exports = router;
