JS获取本机IP地址的2种方法

1.获取本机IP地址方法1：

if(typeof window != 'undefined'){var RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;if (RTCPeerConnection) (()=>{var rtc = new RTCPeerConnection()rtc.createDataChannel(''); //创建一个可以发送任意数据的数据通道rtc.createOffer( offerDesc => { //创建并存储一个sdp数据rtc.setLocalDescription(offerDesc)}, e => { console.log(e)})rtc.onicecandidate =(evt) => { //监听candidate事件if (evt.candidate) {console.log('evt:',evt.candidate)let ip_rule = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/var ip_addr = ip_rule.exec(evt.candidate.candidate)[1]console.log('ip_addr:',ip_addr)   //打印获取的IP地址}}})()else{console.log("没有找到")}
}

2.获取本机IP地址方法2

   //获取用户本地ip的方法
const getUserIP= (onNewIP)=> {let MyPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;let pc = new MyPeerConnection({iceServers: []});let noop = () => {};let localIPs = {};let ipRegex = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/g;let iterateIP = (ip) => {if (!localIPs[ip]) onNewIP(ip);localIPs[ip] = true;};pc.createDataChannel('');pc.createOffer().then((sdp) => {sdp.sdp.split('\n').forEach(function (line) {if (line.indexOf('candidate') < 0) return;line.match(ipRegex).forEach(iterateIP);});pc.setLocalDescription(sdp, noop, noop);}).catch((reason) => {});pc.onicecandidate = (ice) => {if (!ice || !ice.candidate || !ice.candidate.candidate || !ice.candidate.candidate.match(ipRegex)) return;ice.candidate.candidate.match(ipRegex).forEach(iterateIP);};
}getUserIP((ip) => {state.ip=ipconsole.log(ip)console.log(state.ip)});
