问题描述
我已经创建了一个nodejs服务器，它将以IP地址作为响应
I have create a nodejs server which will give response as ip address
app.get('/UserIP', function(req, res) {
console.log(req.connection.remoteAddress);
res.send(JSON.stringify({'ip':req.connection.remoteAddress}));
});
后来我创建了一个客户端，它将获取此ip地址
later i created a client which will get this ip address
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function () {
$.getJSON("http://localhost:7979/userip", function (data) {
$('p').html('IP Address is: ' + res.ip);
});
});
</script>
</head>
<body>
<p></p>
</body>
</html>
我无法将该IP发送到我的客户网站.有些像jsonip.com这样的网站正在使用我的代码.请帮助我了解我在哪里做错了.
