(Chilkat2-Python) JSON: Nested ObjectsHere we have a JSON object that contains nested JSON objects. This example demonstrates how to access the contents of the nested objects. { "name": "donut", "image": { "fname": "donut.jpg", "w": 200, "h": 200 }, "thumbnail": { "fname": "donutThumb.jpg", "w": 32, "h": 32 } }
import sys import chilkat2 json = chilkat2.JsonObject() # This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars). # The presence of whitespace chars for pretty-printing makes no difference to the Load # method. jsonStr = "{\"name\": \"donut\",\"image\":{\"fname\": \"donut.jpg\",\"w\": 200,\"h\": 200},\"thumbnail\":{\"fname\": \"donutThumb.jpg\",\"w\": 32,\"h\": 32}}" success = json.Load(jsonStr) if (success != True): print(json.LastErrorText) sys.exit() # Get the "image" object. # imageObj is a CkJsonObject imageObj = json.ObjectOf("image") if (json.LastMethodSuccess == False): print("image object not found.") sys.exit() print("image: fname=" + imageObj.StringOf("fname") + ", width=" + str(imageObj.IntOf("w")) + ", height="\ + str(imageObj.IntOf("h"))) # Get the "thumbnail" object. # thumbObj is a CkJsonObject thumbObj = json.ObjectOf("thumbnail") if (json.LastMethodSuccess == False): print("thumbnail object not found.") sys.exit() print("thumbnail: fname=" + thumbObj.StringOf("fname") + ", width=" + str(thumbObj.IntOf("w")) + ", height="\ + str(thumbObj.IntOf("h"))) |
