Node.js URL模块
使用url.parse()方法可以解析一个地址，并且会返回带有地址和属性的URL对象
var url = require('url');
var adr = 'http://loclahost:8080/index.html?name=admin&passwd=root&id=201822021';
var res = url.parse(adr,true);
console.log("HOST："+res.host);
console.log("路由名："+res.pathname);
console.log("搜索值："+res.search);
var resnew = res.query;
console.log("用户名："+resnew.name+";密码："+resnew.passwd+";ID号"+resnew.id);
实战演示，路由设置
创造一个Node.js文件并打开后将制定内容给客户端，如果出现错误，就抛出404错误
urlFilename.js
var url = require('url');
var fs = require('fs');
var http = require('http');
http.createServer(function (req, res) {
var q = url.parse(req.url, true);
//读取路由名作为文件名
var filename = "." + q.pathname;
fs.readFile(filename, function(err, data) {
if (err) {
res.writeHead(404, {'Content-Type': 'text/html'});
return res.end("404 Not Found");
}
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(data);
return res.end();
});
}).listen(8080);
console.log("服务已经成功在8080端口运行！");

如果在路由里面输入localhost:8080/other.html后会出现这样的情况
