【报Bug】plus.android.requestPermissions一直返回-1 一直重复申请

操作步骤：

<script>  
export default {  
  data() {  
    return {  
    };  
  },  
 onShow() {  
  plus.android.requestPermissions(  
                    ['android.permission.ACCESS_FINE_LOCATION'],   
                    function(resultObj) {  
                        console.log(resultObj)  
                        var result = 0;  
                        for (var i = 0; i < resultObj.granted.length; i++) {  
                            var grantedPermission = resultObj.granted[i];  
                            console.log('已获取的权限：' + grantedPermission);  
                            result = 1  
                        }  
                        for (var i = 0; i < resultObj.deniedPresent.length; i++) {  
                            var deniedPresentPermission = resultObj.deniedPresent[i];  
                            console.log('拒绝本次申请的权限：' + deniedPresentPermission);  
                            result = 0  
                        }  
                        for (var i = 0; i < resultObj.deniedAlways.length; i++) {  
                            var deniedAlwaysPermission = resultObj.deniedAlways[i];  
                            console.log('永久拒绝申请的权限：' + deniedAlwaysPermission, a);  
                            result = -1  
                        }  
                    },  
                    function(error) {  
                        console.log('申请权限错误：' + error.code + " = " + error.message);  
                    }  
                );  
 }  
};  
</script>

或是将其写成方法放在methods中，依旧会反复申请

预期结果：

plus.android.requestPermissions在放置于onshow周期中，当返回为-1时应该只申请一次

实际结果：

plus.android.requestPermissions在放置于onshow周期中，当返回为-1时会反复申请权限
