jsoncpp序列化和反序列化

#序列化
// json object to json string

void test_serialize() {  
    Json::Value root;  
    Json::FastWriter writer;  
    Json::Value object1;  
    Json::Value object2;  
  
    object1["id"] = 1;  
    object2["name"] = "hello";  
    root.append(object1);  
    root.append(object2);  
  
    std::string jsonStr = writer.write(root);  
    std::cout << jsonStr << std::endl;  
}  

#反序列化

  void test_deserialize() {  
    // sample  
    std::string test = "{\"id\":1,\"name\":\"hello\"}";  
    Json::Reader reader;  
    Json::Value value;  
  
    // deserialize  
    if (reader.parse(test, value)) {  
        int id = value["id"].asInt();  
        std::string name = value["name"].asString();  
        std::cout << id << " " << name << std::endl;  
    } else {  
        std::cout << "parse error" << std::endl;  
    }     
}
