iterate []x.json2.Any

[Brixy]

Hi guys,

I'm trying to convert json to x.json2 in a number of scripts to get rid a the structs.

This is a basic example:

import os
import x.json2

fn main() {
	f_contacts := os.read_file('contacts.json')!
	contacts := json2.decode[json2.Any](f_contacts)!

	for contact in contacts.arr() {
		println(contact['last_name'])
	}
}

Any idea how to get something like this to work? I tried various combinations of arr(), as_map(), to_array() etc.

Thanks a lot in advance!

We learn a lot reading also the tests: https://github.com/vlang/v/blob/master/vlib/x/json2/tests/decoder_test.v

import x.json2

raw_mp := json2.raw_decode('[
	{"name":"Paul","last_name":"McCartney"},
	{"name":"John","last_name":"Lennon"}]
')!
contacts := raw_mp.as_map()
for _, v in contacts {
	contact := v.as_map()
	println('${contact["last_name"]}')
}

McCartney
Lennon

Simpler:

import x.json2

raw := json2.raw_decode('[
	{"name":"Paul","last_name":"McCartney"},
	{"name":"John","last_name":"Lennon"}]
')!
for a in raw.arr() {
	contact := a.as_map()
	println('${contact["last_name"]}')
}

Thank you very much. Both solutions work perfectly.

Thank you also for pointing me to the tests. I have never read any but will do!
