I'm trying to extract the key and the value of an object in array but don't find the proper getter: 

 for (Value::ConstValueIterator itr = document["params"].Begin(); itr != document["params"].End(); ++itr)
{
    for (Value::MemberIterator m = itr->MemberBegin(); m != itr->.MemberEnd(); ++m) {

    }       
}

in the second loop, I want to extract the key and value from the iterator separately. how to do the extraction?

Suppose V is a JSON object which has key-value object. You can retrieve data like this.

const rapidjson::Value& V;
for (Value::ConstMemberIterator iter = V.MemberBegin(); iter != V.MemberEnd(); ++iter){
    printf("%s\t", iter->name.GetString());
    printf("%s\t", iter->value.GetString());
}
