json_enc

Item Description
Syntax json_enc(d)
Feature Encodes a dictionary object into a JSON string.
Parameter d: the dictionary object that you want to encode.
Return value If the function succeeds, a JSON-encoded string is returned. Otherwise, false is returned.
Example 
var_a = []
var_b = ['v1', 'v2']
set(var_a, 'k1', 'v1')
set(var_a, 'k2', var_b)
var_c = '{"k1":"v1","k2":["v1","v2"]}'
say(concat('json_enc=', json_enc(var_a)))
say(concat('json_dec=', get(json_dec(var_c), 'k1')))
Output:
json_enc={"k1":"v1","k2":["v1","v2"]}
json_dec=v1

json_dec

Item Description
Syntax json_dec(s)
Feature Decodes a JSON string into a dictionary.

var_c = '{"k1":"v1","k2":["v1","v2"]}'
say(concat('json_enc=', json_enc(var_a)))
say(concat('json_dec=', get(json_dec(var_c), 'k1')))

json_enc={"k1":"v1","k2":["v1","v2"]}
