Angularjs：$ locationChangeStart检查令牌

Question

我试着检查next是否hasToken但是没有工作我得到错误：

TypeError: Cannot read property 'next' of undefined

任何想法？

app.js

.run(function ($rootScope, $location,$log,User) {

         $rootScope.$on("$locationChangeStart", function (event,next, current,jwtHelper) {

              if(!localStorage.token.next){

                location.path("/signin");
              }

        });

令牌未发现

你可以这样检查

public class MainActivity extends Activity implements SensorEventListener{

        TextView display;
        float g;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        display = (TextView) findViewById(R.id.testView); // Correction
        SensorManager mgr = (SensorManager) getSystemService(SENSOR_SERVICE);
        Sensor GSensor = mgr.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mgr.registerListener(this, GSensor, SensorManager.SENSOR_DELAY_NORMAL);

        String mytext = Float.toString(g);

        display.setText(mytext);


    }
    @Override
    public void onSensorChanged(SensorEvent event){

        float x = event.values[0];
        float y = event.values[1];
        float z = event.values[2];

        g = (x * x + y * y + z *z)/(SensorManager.GRAVITY_EARTH *SensorManager.GRAVITY_EARTH);



    }



    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy){
    }
}
