digitalmars.D.learn - asdf get first value from a json string.
Hi All,
Request your help on how to get the first value of "type" from
the below json, the expected output required is as below,
{"characteristicValue":"TT,TT dev.com,DEV"}
output1: TT
output2: TT dev.com
Code:
/+dub.sdl:
dependency "asdf" version="~>0.6.6"
+/
import std;
import asdf;
void main()
{
string data = `{"items":[{
"hostname":"test01",
"type":[
{"characteristicValue":"TT,TT dev.com,DEV"},
{"characteristicValue":"000"}
]}]}`;
foreach (ref j; parseJson(data)["items"].byElement()) {
writeln(j["type"]) ;
}
}

You need a data structure to work with, eg:
static struct S {
string characteristicValue;
}
foreach (ref j; parseJson(data)["items"].byElement()) {
auto sArr = j["type"].deserialize!(S[]);
writefln("value: %s", s[0].characteristicValue);
}
Then split your S.characteristicValue into tokens with
std.array.split
