Code Example

void UMyGame::GetMultipleCaches(const TArray<FString>& CacheKeys)
{
    // Create cache_keys array
    TArray<TSharedPtr<FJsonValue>> KeysArray;
    for (const FString& Key : CacheKeys)
    {
        KeysArray.Add(MakeShareable(new FJsonValueString(Key)));
    }

    // Create request data
    // Create request body with player information
    TSharedPtr<FJsonObject> Body = FPlayNANOOHelper::CreateRequestBody();
    Body->SetArrayField(TEXT("cache_keys"), KeysArray);

    // Convert to JSON string
    FString JsonBody = FPlayNANOOHelper::ToJsonString(Body);

    // HTTP request
    TSharedRef<IHttpRequest> Request = FHttpModule::Get().CreateRequest();
    Request->SetURL(TEXT("https://service-api.playnanoo.com/cache/v20241201/mget"));
    Request->SetVerb(TEXT("PUT"));
    FPlayNANOOHelper::SetCommonHeaders(Request, true);  // Include auth token
    Request->SetContentAsString(JsonBody);

    Request->OnProcessRequestComplete().BindLambda(
        [](FHttpRequestPtr Req, FHttpResponsePtr Res, bool bSuccess)
    {
        if (bSuccess && Res.IsValid())
        {
            TSharedPtr<FJsonObject> JsonObject;
            TSharedRef<TJsonReader<>> Reader = TJsonReaderFactory<>::Create(Res->GetContentAsString());

            if (FJsonSerializer::Deserialize(Reader, JsonObject))
            {
                const TArray<TSharedPtr<FJsonValue>>* Items;

                    {
                        TSharedPtr<FJsonObject> ItemObj = Item->AsObject();
                        FString Key = ItemObj->GetStringField(TEXT("key"));
                        FString Value = ItemObj->GetStringField(TEXT("value"));
                        UE_LOG(LogTemp, Log, TEXT("Cache: %s = %s"), *Key, *Value);
                    }
                }
            }
