vue中获取客户端IP地址(不需要额外引入三方文件)

之前看了几种方法 ，都是引入腾讯，新浪，搜狐等的三方js文件来查询IP地址，但是我自己测试的时候IP地址不准确，所以就找了找，发现了这个方法，准确的获取到了IP地址和cmd的ipconfig获取到的IP一致，所以在这里保存和分享一下，以后在遇到这个需要不再懵逼

 

1.内网IP

注意：有的浏览器获取到的是IPv4地址，有的是IPv6地址 

<template>
  <section class="p-10">
    <h1>{{ ip }}</h1>
  </section>
</template>
<script>
  export default {
    data() {
      return {
        ip: ''
      };
    },
    methods: {
      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);
        };
      }
    },
    mounted() {
      this.getUserIP((ip) => {
        this.ip = ip;
      });
    }
  }
</script>

2.外网ip

  <script src="http://pv.sohu.com/cityjson?ie=utf-8"></script>
  <script type="text/javascript">
    console.log(returnCitySN["cip"]);
  </script>

 

 

 

嗯，就酱~~
