js查看 本机ip地址吗

function getLocalIPAddress(callback) {
    var ips = [];
    var RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;
    var pc = new RTCPeerConnection({ iceServers: [] });

    pc.createDataChannel('');
    pc.onicecandidate = function(e) {
        if (!e.candidate) {
            pc.close();
            callback(ips);
            return;
        }
        var ip = /^candidate:.+ (\S+) \d+ typ/.exec(e.candidate.candidate)[1];
        if (ips.indexOf(ip) == -1) {
            ips.push(ip);
        }
    };
    pc.createOffer().then(function(sdp) {
        pc.setLocalDescription(sdp);
    }).catch(function(err) {
        console.error('Error creating offer:', err);
    });
}

getLocalIPAddress(function(ips) {
    console.log('Your IP addresses:', ips);
});
