前端Vue中获取本机ip地址

1.打开谷歌浏览器，地址栏输入chrome://flags，进入。
2.搜索Anonymize local IPs exposed by WebRTC，将其设置为Disabled。

methods方法

getUserIP (onNewIP) { // 获取ip地址
    let MyPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection
    let pc = new MyPeerConnection({iceServers: []})
    let noop = function () {}
    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
    function iterateIP (ip) {
        if (!localIPs[ip]) onNewIP(ip)
        localIPs[ip] = true
    }
    pc.createDataChannel('')
    pc.createOffer().then(function (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(function (reason) {
    // An error occurred, so handle the failure to connect
    })
    // seen for candidate events
    pc.onicecandidate = function (ice) {
        if (!ice || !ice.candidate || !ice.candidate.candidate || !ice.candidate.candidate.match(ipRegex)) return
        ice.candidate.candidate.match(ipRegex).forEach(iterateIP)
    }
},

在created中调用ip接口

let that = this
this.getUserIP(function (ip) { // 调用ip接口
   that.ip = String(ip)
   that.$http({
       method: 'post',
       url: url,
       params: {
           ip: that.ip
       }
   }).then(({data}) => { // 成功之后调用initWebSocket
           that.initWebSocket() // 调用ws
           // console.log(data)
       })
   })

获取到相应的数据之后进行下一步操作
