UE 4 Jsonのプロローグと反プロローグ

まずは

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "Http", "Json", "JsonUtilities" });

ヘッダをインポート

#include "Json.h"

 

//string json
TSharedPtr MessageObject = MakeShareable(new FJsonObject);
TSharedRef< TJsonReader<> > Reader = TJsonReaderFactory<>::Create(MessageBody);
FJsonSerializer::Deserialize(Reader, MessageObject);


//Json string
FString TempStr;
TSharedRef> Writer = TJsonWriterFactory<>::Create(&TempStr);
FJsonSerializer::Serialize(MessageObject.ToSharedRef(), Writer);
