java 获取 IP
String ip = "";
String address = "";
try {
// 获取IP地址
ip = InetAddress.getLocalHost().getHostAddress();
// 获取计算机名
// String hostName = InetAddress.getLocalHost().getHostName();
InetAddress ia = InetAddress.getByName(ip);
byte[] mac = NetworkInterface.getByInetAddress(ia).getHardwareAddress();
StringBuffer sb = new StringBuffer();
for (int i = 0; i < mac.length; i++) {
if (i != 0) {
sb.append(“-”);
}
String hexString = Integer.toHexString(mac[i] & 0xFF);
sb.append(hexString.length() == 1 ? “0” + hexString : hexString);
}
address = sb.toString().toUpperCase();
} catch (Exception e) {
e.printStackTrace();
}
vue 获取 IP地址
第一种：
// 获取IP地址
const testScript = document.createElement(‘script’)
testScript.setAttribute(‘charset’, ‘utf-8’)
testScript.setAttribute(‘type’, ‘text/javascript’)
testScript.setAttribute(‘src’, ‘https://pv.sohu.com/cityjson?ie=utf-8’)
document.getElementsByTagName(‘head’)[0].appendChild(testScript)
testScript.onload = function () {
console.log(window.returnCitySN[‘cip’], ‘local’)
}
第二种：
直接使用 window.returnCitySN
console.log(window.returnCitySN)
