jsonpath always return false or array?

[SimonCheung1989]

when i have a data structure like { city1: ['BJ'], city2: 'BJ' }

when i use jsonpath to get the json value, $.city1 it will return ['BJ'] $.city2 it will return ['BJ'] as well, then the question come out, how could i juddge the element type is a String or is an Array?
