任何人都可以告诉我为什么我的服务器地址(主机)是::而不是localhost
var express = require('express');
var app = express();
// respond with "hello world" when a GET request is made to the homepage
app.get('/', function(req, res) {
res.send('hello world');
});
var server = app.listen(3000, function () {
var host = server.address().address;
var port = server.address().port;
console.log('Example app listening at http://%s:%s', host, port);
});
返回
Example app listening at http://:::3000
时,它工作正常
答案 0 :(得分:5)
因为::在使用IPv6时是localhost,就像IPv4中的127.0.0.1一样。
