获取ip, mask, gateway

1.IP
const wifiInfo = await wifiManager.getLinkedInfo();
// ip
const ip = wifiInfo.ipAddress;
this.mLocalWifiIp = this.ipNumberToStr(ip);

2.Get mask and gateway
    const ipInfo = await wifiManager.getIpInfo();
    this.mLocalWifiMask = ipInfo.netmask; //this.ipNumberToStr(ipInfo.netmask); // mask
    this.mLocalWifiGateWay = ipInfo.gateway; //this.ipNumberToStr(ipInfo.gateway); // gateway
3.ipNumberToStr
ipNumberToStr(ipNumber:number): string{
    const ip1 = (ipNumber >> 24) & 0xff;
    const ip2 = (ipNumber >> 16) & 0xff;
    const ip3 = (ipNumber >> & 0xff;
    const ip4 = (ipNumber >> 0) & 0xff;
    let ipStr:string = ip1 + '.' + ip2 + '.' + ip3 + '.' + ip4;
    return ipStr;
  }
