是的，您可以访问 req.url 并手动解析：

  var url = require（'url'）; 
 var url_parts = url.parse（request.url，true）; 
 var query = url_parts.query; 
 

但是，在expressjs中，已经为您完成了，您可以使用 req.query ：

  var id = req.query.id; // $ _GET [id] 
 

Can we get the variables in the query string in Node.js just like we get them in $_GET in PHP?

I know that in Node.js we can get the URL in the request. Is there a method to get the query string parameters?

Yes you can access req.url and parse it manually:

var url = require('url');
var url_parts = url.parse(request.url, true);
var query = url_parts.query;

However, in expressjs it's already done for you and you can simply use req.query for that:

var id = req.query.id; // $_GET["id"]
