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
以下函数涵盖了所有的情况,将会有所帮助
var ip;
if (req.headers['x-forwarded-for']) {
ip = req.headers['x-forwarded-for'].split(",")[0];
} else if (req.connection && req.connection.remoteAddress) {
ip = req.connection.remoteAddress;
} else {
ip = req.ip;
}console.log("client IP is *********************" + ip);
其他回答
请求。headers['x-forwarded-for'] || request.connection.remoteAddress . headers['x-forwarded-for'
如果有x-forward -for报头,则使用它,否则使用. remoteaddress属性。
The x-forwarded-for header is added to requests that pass through load balancers (or other types of proxy) set up for HTTP or HTTPS (it's also possible to add this header to requests when balancing at a TCP level using proxy protocol). This is because the request.connection.remoteAddress the property will contain the private IP address of the load balancer rather than the public IP address of the client. By using an OR statement, in the order above, you check for the existence of an x-forwarded-for header and use it if it exists otherwise use the request.connection.remoteAddress.
我在nginx后面使用express和
req.headers.origin
对我有用吗
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
在nodejs中简单获取远程ip:
var ip = req.header('x-forwarded-for') || req.connection.remoteAddress;
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。
