JSONCPP使用

{"key":"value","key1":"value1"}

Json::Value value;
Json::Reader reader;
Json::Value::iterator iter;
Json::Value::Members members;
bool parsingSuccessful = reader.parse( json_str, value );
if (parsingSuccessful) {
members = value.getMemberNames();
for (Json::Value::Members::iterator it = members.begin();
it != members.end(); ++it) {
std::string name = *it;
std::string value_str = value[name].asString();
cout<<name<<":"<<value_str<<endl;
}
}
