JSON Paths that need Double Quotes

See more JSON Examples

This example explains and demonstrates the situations where parts within a JSON path need to be enclosed in double-quotes. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // Imagine we have the following JSON:

  // 	{ 
  // 	  "Meta Data": { 
  // 	    "1: Symbol": "MSFT",
  // 	    "2: Indicator": "Relative Strength Index (RSI)",
  // 	    "3: Last Refreshed": "2017-07-28 09:30:00",
  // 	    "4: Interval": "15min",
  // 	    "5: Time Period": 10,
  // 	    "6: Series Type": "close",
  // 	    "7: Time Zone": "US/Eastern Time"
  // 	  },
  // 	  "Technical Analysis: RSI": { 
  // 	    "2017-07-28 09:30": { 
  // 	      "RSI": "38.6964"
  // 	    },
  // 	    "2017-07-27 16:00": { 
  // 	      "RSI": "50.0088"
  // 	    } 
  // 	} 

  // The path to the RSI valud 38.6964 is Technical Analysis: RSI.2017-07-28 09:30.RSI

  // Whenever a path part contains a SPACE or "." char, that part must be enclosed
  // in double quotes.  For example:

  final json = CkJsonObject();
  json.loadFile('qa_data/json/rsi.json');

  print('RSI: ${json.stringOf('"Technical Analysis: RSI"."2017-07-28 09:30".RSI')}');

  // output is 38.6964
