vue获取用户ip地址

vue获取用户ip地址（仅限IE浏览器，谷歌无效）
具体代码如下：

/**
	data里定义变量ip
**/
ip = ''

/**
	mounted添加下面方法
**/
this.getUserIP((ip) => {
        this.ip = ip
        console.log('this.ip====', this.ip)
      })
/**
	methods添加下面方法
**/
      // 获取用户本地ip的方法
      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)
        }
      },
