一段代码检查你的浏览器IP泄露（WebRTC老话题了）

[md]# 简介

老话题来水一手哈哈，原理很简单，就是浏览器的WebRTC功能可能导致你的ip泄露，很可能不走你的浏览器代理，快来检测一下吧~

# 代码

直接复制这段代码到你的F12控制台执行，如果有ip输出说明你的ip可能存在泄露的情况~

```javascript
(function() {
// WebRTC IPs
const iceServers = [
      { urls: 'stun:stun.l.google.com:19302' },
      { urls: 'stun:stun1.l.google.com:19302' },
      { urls: 'stun:stun2.l.google.com:19302' },
      { urls: 'stun:stun3.l.google.com:19302' },
      { urls: 'stun:stun4.l.google.com:19302' },
];

function getUserIPs(callback) {
      const myPeerConnection = new RTCPeerConnection({ iceServers });
      myPeerConnection.createDataChannel("");
      myPeerConnection.createOffer().then(offer => myPeerConnection.setLocalDescription(offer));

      myPeerConnection.onicecandidate = function(event) {
         if (event.candidate) {
            const parts = event.candidate.candidate.split(' ');
            const ip = parts[4];
            callback(ip);
         }
      };
}

getUserIPs((ip) => {
      const ipv4Regex = /^(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$/;
      const ipv6Regex = /^(([0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,7}:|([0-9a-fA-F]{1,4}:){1,6}:[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,5}(:[0-9a-fA-F]{1,4}){1,2}|([0-9a-fA-F]{1,4}:){1,4}(:[0-9a-fA-F]{1,4}){1,3}|([0-9a-fA-F]{1,4}:){1,3}(:[0-9a-fA-F]{1,4}){1,4}|([0-9a-fA-F]{1,4}:){1,2}(:[0-9a-fA-F]{1,4}){1,5}|[0-9a-fA-F]{1,4}:((:[0-9a-fA-F]{1,4}){1,6})|:((:[0-9a-fA-F]{1,4}){1,7}|:)|fe80:(:[0-9a-fA-F]{0,4}){0,4}%[0-9a-zA-Z]{1,}|::(ffff(:0{1,4}){0,1}:){0,1}(([0-9a-fA-F]{1,4}:){1,4}|((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9]))|([0-9a-fA-F]{1,4}:){1,4}:((25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9])\.){3,3}(25[0-5]|(2[0-4]|1{0,1}[0-9]){0,1}[0-9]))$/;
      if (ipv4Regex.test(ip)) {
         console.log('WebRTC IPv4 Address:', ip);
      } else if (ipv6Regex.test(ip)) {
      console.log('WebRTC IPv6 Address:', ip);
      } else {
      console.log('WebRTC Local IP Address:', ip);
      }
      });
      })();
```

# 修复建议

如果存在ip泄露的情况推荐安装一个插件阻止泄露，例如Chrome自己的[webrtc-network-limiter](https://chromewebstore.google.com/detail/webrtc-network-limiter/npeicpdbkakmehahjeeohfdhnlpdklia)[/md]

直接装个chrome插件禁掉就好了
