(CkPython) Demonstrates how to Handle Large Integers in JSONSee more JSON ExamplesDemonstrates how to handle large integers in JSON. (Integers larger than what can fit in a 32-bit signed integer.)
import sys import chilkat # Let's say your JSON has this: # { # "id": 20000000001234567 # } json = chilkat.CkJsonObject() success = json.LoadFile("qa_data/json/large_int.json") if (success == False): print(json.lastErrorText()) sys.exit() # The integer is too large for a 32-bit signed integer that is returned by IntOf. # The result will be something that wrapped around and could be negative. # In this case it would be: -543893881 id = json.IntOf("id") print("id: " + str(id)) # The solution is to read the integer value as a string, and then use the features in your programming language # to convert from a string to a 64-bit integer. # # Alternatively, you may wish to simply hold the value as a string. If, for example, the integer simply references # an order ID, an account ID, etc., then there's no need to convert to an integer value. You're not going to be doing # mathematical operations on it anyway. This is usually the case for large integers -- they typically exist # in JSON as an account ID. # You can get any JSON value as a string: accountId = json.stringOf("id") print("accountId: " + accountId) # Sample output: # id: -543893881 # accountId: 20000000001234567 |
