Hi,
This is what you want:
#include <iostream>
#include <cxxtools/json.h>
int main()
{
cxxtools::SerializationInfo si;
si.addMember("success") <<= true;
cxxtools::SerializationInfo& data = si.addMember("data");
data.setCategory(cxxtools::SerializationInfo::Array);
cxxtools::SerializationInfo& datamember = data.addMember("");
datamember.addMember("id") <<= 5;
datamember.addMember("account") <<= "user1";
datamember.addMember("group_id") <<= 1;
cxxtools::SerializationInfo& group = datamember.addMember("group");
group.addMember("id") <<= 1;
group.addMember("name") <<= "Administrators";
cxxtools::JsonSerializer j;
j.beautify(true);
j.plainkey(true);
j.begin(std::cout)
.serialize(si)
.finish();
}
I changed some other things also. It is always helpful to give variables
good names. s1 or s2 is so nothing.
I still suggest to put that into a serialization operator in a object.
You may well create a object, which has some optional attributes.
