獲取局域網ip和mac（如果電腦沒有直接連接外網），否則獲取公網ip

通過第三放獲取公網ip

如上方案在Android,Windows，linux都成功了，可能有些地方考慮不太周全，但應該覆蓋了90-95%的PC和Android系統，對了，貌似不支持Android 2.2，

不過Android本身就可獲取mac和IP,代碼如下

?public?Map<String,?Object>??getLocalNetworkinfo(?){??Map<String,?Object>?ipNetInfo?=?new?HashMap<String,?Object>();WifiManager?wifiManager?=?(WifiManager)?mContext.getSystemService(Context.WIFI_SERVICE);WifiInfo?connInfo?=?wifiManager.getConnectionInfo();String?macAddress?=?connInfo.getMacAddress();//mac地址String?ssid?=?connInfo.getSSID();?//ssidString?bssid?=?connInfo.getBSSID();?int?rssi?=?connInfo.getRssi();//信號強度String?speed?=?connInfo.getLinkSpeed()+WifiInfo.LINK_SPEED_UNITS;//網速int?networkId?=?connInfo.getNetworkId();?//網絡號String?ip?=?Formatter.formatIpAddress(connInfo.getIpAddress());DhcpInfo?dhcpInfo?=?wifiManager.getDhcpInfo();??String?gateway?=?Formatter.formatIpAddress(dhcpInfo.gateway);//網關String?netmask?=?Formatter.formatIpAddress(dhcpInfo.netmask);//子網掩碼ipNetInfo.put("mac",?macAddress);ipNetInfo.put("ip",?ip);ipNetInfo.put("gateway",?gateway);ipNetInfo.put("netmask",?netmask);ipNetInfo.put("ssid",?ssid);ipNetInfo.put("rssi",?rssi);ipNetInfo.put("bssid",?bssid);ipNetInfo.put("speed",?speed);ipNetInfo.put("networkId",?networkId);Log.e("IP-MAC-2",ipNetInfo);return?ipNetInfo;?}//信道獲取 public?static?int?getCurrentChannel(Context?context)? {WifiManager?wifiManager?=?(WifiManager)?context.getSystemService(Context.WIFI_SERVICE);WifiInfo?wifiInfo?=?wifiManager.getConnectionInfo();//?當前wifi連接信息ListscanResults?=?wifiManager.getScanResults();for?(ScanResult?result?:?scanResults)?{if?(result.BSSID.equalsIgnoreCase(wifiInfo.getBSSID())&&?result.SSID.equalsIgnoreCase(wifiInfo.getSSID().substring(1,?wifiInfo.getSSID().length()?-?1)))?{return?getChannelByFrequency(result.frequency);}}return?-1;}/***?根據頻率獲得信道*?*?@param?frequency*?@return*/public?static?int?getChannelByFrequency(int?frequency)?{int?channel?=?-1;switch?(frequency)?{case?2412:channel?=?1;break;case?2417:channel?=?2;break;case?2422:channel?=?3;break;case?2427:channel?=?4;break;case?2432:channel?=?5;break;case?2437:channel?=?6;break;case?2442:channel?=?7;break;case?2447:channel?=?8;break;case?2452:channel?=?9;break;case?2457:channel?=?10;break;case?2462:channel?=?11;break;case?2467:channel?=?12;break;case?2472:channel?=?13;break;case?2484:channel?=?14;break;case?5745:channel?=?149;break;case?5765:channel?=?153;break;case?5785:channel?=?157;break;case?5805:channel?=?161;break;case?5825:channel?=?165;break;}return?channel;}
