JS获取本机IP地址的2种方法_javascript技巧_

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")} }

 //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=ip console.log(ip) console.log(state.ip) });
