wrap cJSON for vlang.
V already has the standard json module base on cJSON,but only public json.encode() and json.decode().
sometimes we may need to use cJSON directly.
-
via vpm
v install lydiandy.cjson -
via source
git clone git@github.com:lydiandy/cjson.git ln -s your/path ~/.vmodules/cjson
module main
import cjson // import lydiandy.cjson
struct User {
name string
age int
}
fn main() {
// cjson print
u := User{name:'tom', age:18}
root := cjson.create_object()
cjson.add_item_to_object(root, "name", cjson.create_string(u.name))
cjson.add_item_to_object(root, "age", cjson.create_number(u.age))
json_str := cjson.json_print(root)
println(json_str)
// cjson parse
json_content:='{"name":"jack","age":22}'
res := cjson.json_parse(json_content)
name := cjson.get_object_item(res, 'name')
age := cjson.get_object_item(res, 'age')
println(name.valuestring)
println(age.valueint)
