有一个 ReactNative 库用于获取有关设备网络的信息：

react-native网络信息

// require module
var NetworkInfo = require('react-native-network-info');

// Get Local IP
NetworkInfo.getIPAddress(ip => {
  console.log(ip);
});

import publicIP from 'react-native-public-ip';

publicIP()
.then(ip => {    
  console.log(ip);
  // '47.122.71.234'
})
.catch(error => {
  console.log(error);
  // 'Unable to get IP address.'
});

更多信息：https : //www.npmjs.com/package/react-native-public-ip

这个包提供了以下 apis

npm i react-native-network-info



import { NetworkInfo } from "react-native-network-info";
 
// Get Local IP
NetworkInfo.getIPAddress().then(ipAddress => {
  console.log(ipAddress);
});
 
// Get IPv4 IP (priority: WiFi first, cellular second)
NetworkInfo.getIPV4Address().then(ipv4Address => {
  console.log(ipv4Address);
});
 
// Get Broadcast
NetworkInfo.getBroadcast().then(broadcast => {
  console.log(broadcast);
});
 
// Get SSID
NetworkInfo.getSSID().then(ssid => {
  console.log(ssid);
});
 
// Get BSSID
NetworkInfo.getBSSID().then(bssid => {
  console.log(bssid);
});
 
// Get Subnet
NetworkInfo.getSubnet().then(subnet => {
  console.log(subnet);
});
 
// Get Default Gateway IP
NetworkInfo.getGatewayIPAddress().then(defaultGateway => {
  console.log(defaultGateway);
});
 
// Get frequency (supported only for Android)
NetworkInfo.getFrequency().then(frequency => {
  console.log(frequency);
});

只是提供另一个库：https : //github.com/react-native-netinfo/react-native-netinfo#netinfostate

这个有更多的功能，看起来有一个更大的社区在使用它。
