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
})

当前回答
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
}
其他回答
如果你有多个ip,这对我来说是可行的:
Var ipaddress = (req。标题(“x-forwarded-for”)| | req.connection.remoteAddress | | req.socket.remoteAddress | | req.connection.socket.remoteAddress) .split (", ") [0];
首先,在项目中安装request-ip
import requestIp from 'request-ip';
const clientIp = requestIp.getClientIp(req);
console.log(clientIp)
如果使用localhost,结果可能是::1,因为::1是真实的IP地址,是localhost的IPV6表示法。
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
我在nginx后面使用express和
req.headers.origin
对我有用吗
如果您使用的是快速版3。X或更大,您可以使用信任代理设置(http://expressjs.com/api.html#trust.proxy.options.table),它将遍历X -forward -for报头中的地址链,并将链中尚未配置为受信任代理的最新IP放入req对象的IP属性中。
