Serialization and deserialization of basic data in comm
Based on the jsoncpp library, written by C++, used to provide serialization and deserialization of network data
Several classes used
Json::Value can represent all types, int,float,string, etc.
Json::Reader parses json strings into Value, deserializes, and uses the Parse function
Json::Writer converts Value to json string and serializes
Its two subclasses: Json::FastWriter and Json::StyledWriter two different display styles
