如何检索客户端 ip 地址并使用 node.js 查找位置

Question

我曾尝试使用以下方法，但在托管应用程序时。 我得到了我们托管的应用程序的 ip 地址。 我也使用过 req.ip和req.socket.remoteAddress但它返回本地主机 ip Ie, ::1

here is what I tried.

var express = require('express');
var request = require('request');
var app = express();
const IPData = require("ipdata").default;
require('dotenv').config();

const apiKey = process.env.API_KEY;
const ipdata = new IPData(apiKey);

app.get('/location', async (req, res) => {
    try{
        request.get('http://ipinfo.io/ip', (error, response, body) => {
            if (!error && response.statusCode == 200) {
                let clientIp = req.headers["x-forward-ip"] || body
                console.log(body);
                ipdata.lookup(clientIp)
                    .then((data) => {
                        console.log(data);
                        return res.json({
                            city: data.city,
                            region: data.region,
                            country: data.country_name,
                            postal: data.postal
                        });
                    })
                    .catch((error) => {
                        console.log(error);
                        res.status(500).send('Error looking up location');
                    });
            }
        });

    }catch(error) {
        console.log(error);
        res.status(500).send('Error looking up location');
    }
   
});

app.listen(8000, () => {
    console.log('Server started on port 8000');
});

 /// try this 

const express = require('express')
const app = express()
const IpGeoLocation = require('ip-geolocation-api-javascript-sdk')
app.get('/', (req, res) => {
    // Get client's IP address
    const clientIp = req.connection.remoteAddress
    // Initialize IpGeoLocation with your API key
    const apiKey = 'YOUR_API_KEY'
    const ipGeoLocation = new IpGeoLocation(apiKey)
    // Get location information for the client's IP address
    ipGeoLocation.getGeoLocation(clientIp)
        .then(location => {
            console.log(location)
            res.send(location)
        })
        .catch(error => {
            console.error(error)
            res.status(500).send(error)
        })
})
app.listen(3000, () => {
    console.log('Server listening on port 3000')
})

 const ipGeoLocation = require('ip-geolocation-node'); const clientIp = req.connection.remoteAddress; ipGeoLocation.getGeoLocation(clientIp).then(location => { console.log(location) }).catch(error => { console.error(error) });
