javascript - JS+REST+NodeJS: How to parse a JSON list from a JSON object -

-

in python have json object, inside fields there 1 (field3) contains list of json objects.

this object passed python script rest service based in js express framework:

urllib.request.urlopen(     urllib.request.request(     url="http://"+self.__host+_":"+self.__port+"/api"+restmethod,     data=urllib.parse.urlencode(objdata).encode('utf8'),     headers=self.__headertoken,method=httpmethod) )

but when server receives json automatically recognizes field33 string instead of json list.

{ field1: '',   field2: '',   field3: '[{\'field31\': \'\', \'field32\': \'\', \'field33\':\'\',\'field34\': \'\', \'field34\': \'0.00\'}]',   field4: '' }

so when try obj.field3[0] returns string rather json list.

i tried json.parse(string) , json.stringify(object) still cannot access json list , elements obj.field3.field31

how can recover json list parent json field? thanks

field3 should be:

'[{\"field31\": \"\",...}]',

or simply:

'[{"field31": "",...}]',

single quote ' cause error when parsed json.parse.

and obj.field3 array, field31 value, should use:

obj.field3[0].field31
