JS获取本机IP地址的方法（附上解决浏览器无法获取IP的方法）,第1张

获取本机IP地址： 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")} } 如果电脑没获取到，基本上是因为浏览器限制了，解除方法如下： 解决方案： 火狐(FireFox) 删除隐藏IP 浏览器输入 about:config 搜索配置 media.peerconnection.enabled 改为false ( 刷新程序,IP正常显示 ) 谷歌(Chrome) 删除隐藏IP 浏览器输入：chrome://flags/#enable-webrtc-hide-local-ips-with-mdns 把 Anonymize local IPs exposed by WebRTC 设置为 disabled ( 刷新程序,IP正常显示 )
