如何从控制器内确定给定请求的IP地址?例如(在快递中):
app.post('/get/ip/address', function (req, res) {
// need access to IP address here
})

这里有很多很棒的观点,但没有一个是全面的,所以这里是我最终使用的:
function getIP(req) {
// req.connection is deprecated
const conRemoteAddress = req.connection?.remoteAddress
// req.socket is said to replace req.connection
const sockRemoteAddress = req.socket?.remoteAddress
// some platforms use x-real-ip
const xRealIP = req.headers['x-real-ip']
// most proxies use x-forwarded-for
const xForwardedForIP = (() => {
const xForwardedFor = req.headers['x-forwarded-for']
if (xForwardedFor) {
// The x-forwarded-for header can contain a comma-separated list of
// IP's. Further, some are comma separated with spaces, so whitespace is trimmed.
const ips = xForwardedFor.split(',').map(ip => ip.trim())
return ips[0]
}
})()
// prefer x-forwarded-for and fallback to the others
return xForwardedForIP || xRealIP || sockRemoteAddress || conRemoteAddress
}

你可以使用request-ip来获取用户的ip地址。它处理了很多不同的边界情况,其中一些在其他答案中提到过。
披露:我创建了这个模块
安装:
npm install request-ip
在你的应用中:
var requestIp = require('request-ip');
// inside middleware handler
var ipMiddleware = function(req, res, next) {
var clientIp = requestIp.getClientIp(req); // on localhost > 127.0.0.1
next();
};
希望这能有所帮助
Var ipaddress = (req。标题(“x-forwarded-for”)| | req.connection.remoteAddress | | req.socket.remoteAddress | | req.connection.socket.remoteAddress) .split (", ") [0];
在Typescript中使用ValidatorJS。下面是NodeJS中间件:
// Extract Client IP Address
app.use((req, res, next) => {
let ipAddress = (req.headers['x-forwarded-for'] as string || '').split(',')[0]
if (!validator.isIP(ipAddress))
ipAddress = req.socket.remoteAddress?.toString().split(':').pop() || ''
if (!validator.isIP(ipAddress))
return res.status(400).json({errorMessage: 'Bad Request'})
req.headers['x-forwarded-for'] = ipAddress
next()
})
在这里,我假设所有请求都应该有一个有效的IP地址,因此如果没有找到有效的IP地址,则返回一个代码为400的响应。
在节点10.14中,在nginx后面,你可以通过nginx头请求它来检索ip,就像这样:
proxy_set_header X-Real-IP $remote_addr;
然后在你的app.js中:
app.set('trust proxy', true);
在那之后,你想让它出现的地方:
var userIp = req.header('X-Real-IP') || req.connection.remoteAddress;
如果你使用express.js,
app.post('/get/ip/address', function (req, res) {
res.send(req.ip);
})
