使用此代码，我可以接收请求，但我无法回复。它显示var url = require('url'); var http = require('http'); http.createServer(function (req, res) { var url_parts = url.parse(req.url, true); var q = url_parts.query; console.log(q.query); res.setHeader('Content-Type', 'application/json'); res.send(JSON.stringify({ a: 1 })); console.log(q.query); }).listen(8080);

您需要res.end代替res.send。 res.send是express模块的一部分，而不是核心http module的一部分。

JavaScript节点js`res.send不是函数错误`
