前端获取内网IP：
定义函数：//获取内网ipgetIPs(){let _this = this;var RTCPeerConnection = window.RTCPeerConnection || window.webkitRTCPeerConnection || window.mozRTCPeerConnection;if (RTCPeerConnection) (function () {var rtc = new RTCPeerConnection({iceServers:[]});if (1 || window.mozRTCPeerConnection) {rtc.createDataChannel('', {reliable:false});};rtc.onicecandidate = function (evt) {if (evt.candidate) grepSDP("a="+evt.candidate.candidate);};rtc.createOffer(function (offerDesc) {grepSDP(offerDesc.sdp);rtc.setLocalDescription(offerDesc);}, function (e) { console.warn("offer failed", e); });var addrs = Object.create(null);addrs["0.0.0.0"] = false;function updateDisplay(newAddr) {if (newAddr in addrs) return;else addrs[newAddr] = true;var displayAddrs = Object.keys(addrs).filter(function (k) { return addrs[k]; });for(var i = 0; i < displayAddrs.length; i++){if(displayAddrs[i].length > 16){displayAddrs.splice(i, 1);i--;}}console.log('内网ip',displayAddrs[0]);//打印出内网ip_this.user.ip_in = displayAddrs[0];//获取内网ip}function grepSDP(sdp) {var hosts = [];sdp.split('\r\n').forEach(function (line, index, arr) { if (~line.indexOf("a=candidate")) { var parts = line.split(' '), addr = parts[4],type = parts[7];if (type === 'host') updateDisplay(addr);} else if (~line.indexOf("c=")) { var parts = line.split(' '),addr = parts[2];updateDisplay(addr);}});}})();else{console.log("请使用主流浏览器：chrome,firefox,opera,safari");}},
调用函数：
mounted(){let _this = this;_this.getIPs();//获取内网ip}
前端获取外网IP:
//index.html<script src="/cityjson?ie=utf-8"></script>//vue组件的js：<script>document.write(returnCitySN["cip"]);let ip_out = returnCitySN["cip"];//获取外网IPlogin(){let _this = this;_this.user.ip_out = ip_out;}</script>
vue项目中：
cdn方式引入的话
首先有一点要求, script 必须在 index.html 中的
上面
在 main.js 中 通过 window 获取对象
const Foo = window.foo
Vue.prototype.Foo = Foo
vue 文件里:
this.Foo(params)
