How can I get the local IP address in Node.js?
提问by deltanovember
I'm not referring to
我不是指
127.0.0.1
127.0.0.1
But rather the one that other computers would use to access the machine e.g.
而是其他计算机用来访问机器的那个，例如
192.168.1.6
192.168.1.6

var os = require('os');
var interfaces = os.networkInterfaces();
var addresses = [];
for (var k in interfaces) {
for (var k2 in interfaces[k]) {
var address = interfaces[k][k2];
if (address.family === 'IPv4' && !address.internal) {
addresses.push(address.address);
}
}
}
console.log(addresses);

My version which was needed for a compact and single file script, hope to be useful for others:
我的版本需要一个紧凑的单文件脚本，希望对其他人有用：
var ifs = require('os').networkInterfaces();
var result = Object.keys(ifs)
.map(x => [x, ifs[x].filter(x => x.family === 'IPv4')[0]])
.filter(x => x[1])
.map(x => x[1].address);
Or to answer the original question:
或者回答原来的问题：
var ifs = require('os').networkInterfaces();
var result = Object.keys(ifs)
.map(x => ifs[x].filter(x => x.family === 'IPv4' && !x.internal)[0])
.filter(x => x)[0].address;

A very small module that does just this.
一个非常小的模块，可以做到这一点。

Ever since Node version 0.9.6 there is a simple way to get the server's IP address based on each request. This could be important if your machine has multiple IP addresses or even if you are doing something on localhost.
从 Node 0.9.6 版本开始，就有一种简单的方法可以根据每个请求获取服务器的 IP 地址。如果您的机器有多个 IP 地址，或者即使您在 localhost 上执行某些操作，这可能很重要。
req.socket.localAddresswill return the address of the machine node is running on based on the current connection.
req.socket.localAddress将返回基于当前连接运行的机器节点的地址。
If you have a public IP address of 1.2.3.4and someone hits your node server from the outside then the value for req.socket.localAddresswill be "1.2.3.4".
如果你有一个公网IP地址1.2.3.4，有人从外面打你的节点服务器，然后该值req.socket.localAddress会"1.2.3.4"。
If you hit the same server from localhost then the address will be "127.0.0.1"
如果您从 localhost 访问同一台服务器，则地址将是 "127.0.0.1"
If your server has multiple public addresses then the value of req.socket.localAddresswill be the correct address of the socket connection.
如果您的服务器有多个公共地址，那么 的值req.socket.localAddress将是套接字连接的正确地址。
