企业网络基础设施物理安全面临全新挑战-CFANZ编程社区

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