一、Node.js實現代碼
var http = require('http');
var util = require('util');
/**
* 根據 ip 獲取獲取地址信息
*/
var getIpInfo = function(ip, cb) {
var sina_server = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=';
var url = sina_server + ip;
http.get(url, function(res) {
var code = res.statusCode;
if (code == 200) {
res.on('data', function(data) {
try {
cb(null, JSON.parse(data));
} catch (err) {
cb(err);
}
});
} else {
cb({ code: code });
}
}).on('error', function(e) { cb(e); });
};
getIpInfo('220.181.111.85', function(err, msg) {
console.log('城市: ' + msg.city);
console.log('msg: ' + util.inspect(msg, true, 8));
})
請求結果：
城市: 徐州
{
"ret": 1,
"start": "49.68.0.0",
"end": "49.68.255.255",
"country": "中國",
"province": "江蘇",
"city": "徐州",
"district": "",
"isp": "電信",
"type": "",
"desc": ""
}
二、PHP實現代碼
<?
$ip = "220.181.111.85";
$url = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=$ip";
$data = file_get_contents($url);
$result = json_decode($data);
echo "城市:" . $result->city . "<br>";
print_r($result);
?>
請求結果:
城市:徐州
