一、Node.js实现代码
var http = require('http');
var util = require('util');
/**
* 根据 ip 获取获取地址信息
*/
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));
