如何使用rapidjson将对象序列化为std :: string(实现序列化)? [英] How to serialize object to std::string using rapidjson (Implemented serialize)?

问题描述

如何使用RapidJSON将对象序列化为std :: string? 我已经实现

How to serialize object to std::string using rapidjson ? I have implemented

class Person{
public:
    std::string name;
    uint64 id; // uint64 is typedef

    template <typename Writer>
    void Serialize(Writer& writer) const {
        writer.StartObject();
        writer.String("name");
        writer.String(name);
        writer.String(("id"));
        writer.Uint64(id);
        writer.EndObject();
    }
     std::string serialize(){
        FileStream s(stdout);
        PrettyWriter<FileStream> writer(s);   
        Serialize(writer);
        return  ? /// There is a problem

    }
}

问题在序列化函数中返回什么?

problem is in serialize function what to return ?

问题已经很老了，如果您仍在寻找答案，那么这里是@Lightness Races in Orbit建议的问题

Question is pretty old, in case you're still looking for answer, then here is the one as suggested by @Lightness Races in Orbit

class Person{
public:
    std::string name;
    uint64 id; // uint64 is typedef

    template <typename Writer>
    void Serialize(Writer& writer) const {
        writer.StartObject();
        writer.String("name");
        writer.String(name);
        writer.String(("id"));
        writer.Uint64(id);
        writer.EndObject();
    }
     std::string serialize(){
        StringBuffer s;
        Writer<StringBuffer> writer(s);
        Serialize(writer);
        return  s.GetString();
    }
}
