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
})

你可以像这样快速获取用户Ip
req.ip
在这个例子中,我们获取了用户的Ip,然后用req.ip把它发回给用户
app.get('/', (req, res)=> {
res.send({ ip : req.ip})
})

也有同样的问题…im也是新的javascript,但我解决了这个与req.connection.remoteAddress;这给了我IP地址(但在ipv6格式::ffff.192.168.0.101),然后.slice删除前7位数字。
var ip = req.connection.remoteAddress;
if (ip.length < 15)
{
ip = ip;
}
else
{
var nyIP = ip.slice(7);
ip = nyIP;
}
你可以保持DRY,只使用支持IPv4和IPv6的node-ipware。
安装:
npm install ipware
在你的app.js或中间件中:
var getIP = require('ipware')().get_ip;
app.use(function(req, res, next) {
var ipInfo = getIP(req);
console.log(ipInfo);
// { clientIp: '127.0.0.1', clientIpRoutable: false }
next();
});
它将尽最大努力获取用户的IP地址或返回127.0.0.1,以表明它无法确定用户的IP地址。查看README文件中的高级选项。
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];
如果使用express…
req.ip
我在查这个,然后我想,等等,我用的是快递。咄。
我试过了,但都没用,
console.log(clientIp);
console.log(req.ip);
console.log(req.headers['x-forwarded-for']);
console.log(req.connection.remoteAddress);
console.log(req.socket.remoteAddress);
console.log(req.connection.socket.remoteAddress.split(",")[0]);
当在Nginx代理后运行Express应用程序时,你必须将应用程序变量信任代理设置为true。Express提供了其他一些信任代理值,您可以在它们的文档中查看这些值,但以下步骤对我来说是有效的。
app.set('trust proxy', true)
App.set('信任代理',true);
在Nginx中添加proxy_set_header X-Forwarded-For $remote_addr 服务器块的配置。
位置/ { proxy_pass http://localhost: 3001; proxy_http_version 1.1; 升级$http_upgrade; 连接“升级”; 主机$ Host; proxy_set_header X-Forwarded-For $remote_addr;#这一行 proxy_cache_bypass http_upgrade美元; }
对象中读取客户端的IP地址 req.header('x-forwarded-for')或req.connection.remoteAddress;ipfilter的完整代码
module.exports = function(req, res, next) { let enable = true; // true/false let blacklist = ['x.x.x.x']; let whitelist = ['x.x.x.x']; let clientIp = req.header('x-forwarded-for') || req.connection.remoteAddress; if (!clientIp) { return res.json('Error'); } if (enable && paths.some((path) => (path === req.originalUrl))) { let blacklist = blacklist || []; if (blacklist.some((ip) => clientIp.match(ip) !== null)) { return res.json({ status: 401, error: 'Your IP is black-listed !'}); } let whitelist = whitelist || []; if (whitelist.length === 0 || whitelist.some((ip) => clientIp.match(ip) !== null)) { next(); return; } else { return res.json({ status: 401, error: 'Your IP is not listed !'}); } } next(); };
