uni-app 获取手机的mac安卓

getMacAddress: function(){

                            var wifiInfo = wifiManager.getConnectionInfo();  
                            var macAddress = wifiInfo.getMacAddress();  
                            console.log("macAddress <6.0", macAddress);  
                    }                     
                    sendMac=(macAddress!=null?macAddress:"");  
                }  
            },

6.0以上得获取出来得mac地址与路由器上得mac不一样啊
