Question

我只想在我的主人身上进行测试。

node -v 7.4.0 npm -v 4.0.5

const http = require('http');
const hostname = '0.0.0.0';
const port = 3000;
const server = http.createServer((req, res) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'text/plain');
        res.end('Hello World\n');
});
server.listen(port, hostname, () => {
        console.log(`Server running at http://${hostname}:${port}/`);
});
