UE4 C++ 把Json字符串读取为自定义的结构体

需要解析的字符串

{
    "type": "UnrealEngine",
    "key": "sync_sc",
    "data": {
        "episode": "E01",
        "sc": "Sc01",
        "cam": "Cam001",
        "referenceAsset": {
            "character": [
                "zhangsan",
                "lisi",
                "wangwu"
            ],
            "props": [
                "Knife",
                "Gun"
            ]
        }
    }
}

1. 定义结构体

结构体变量名要和Json字符串的键对应起来

USTRUCT(BlueprintType)
struct Fsync_sc_data_referenceAsset
{
	GENERATED_BODY()
public:
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "DataStruct")
		TArray<FString> character;
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "DataStruct")
		TArray<FString> props;
};

USTRUCT(BlueprintType)
struct Fsync_sc_data
{
	GENERATED_BOD
