How to implement Emit method to support MessageList?

[CheaterScript]

Thank you for your response. My question wasn't very clear. The main issue I'm facing is not knowing how to send a MessageList through the Emit method. I've attempted to implement an interface myself, and it looks like this:

void USocketIOClientComponent::EmitMessages(const FString& EventName, const TArray<TSharedPtr<FJsonValue>>& Messages, const FString& Namespace)
{
	if (Messages.Num() <= 0)
	{
		//Set the message is not null
		TSharedPtr<FJsonValue> JsonMessage = MakeShareable(new FJsonValueNull);

		NativeClient->Emit(EventName, JsonMessage, nullptr, Namespace);
		return;
	}

	sio::message::list* MessageList = new sio::message::list();

	for (int i = 0; i < Messages.Num(); i++)
	{
		MessageList->push(USIOMessageConvert::ToSIOMessage(Messages[i]));
	}

	NativeClient->EmitRaw(EventName, *MessageList, nullptr, Namespace);

	delete MessageList;
}

I'm not sure if there's already a solution like this in the plugin, but my current implementation seems to meet my needs.
Thank you for all your assistance.

Can you point to socket.io protocol documentation of your requested feature?

I haven't found an exact example, but it should be similar to the image below：

This is what the JavaScript client looks like after encoding:

This looks like just a multiparam message which is supported via second param on function, see e.g. https://github.com/getnamo/SocketIOClient-Unreal?tab=readme-ov-file#emit-with-callback and https://github.com/getnamo/SocketIOClient-Unreal?tab=readme-ov-file#binding-events-to-functions

Or in c++ via

SocketIOClient-Unreal/Source/SocketIOClient/Public/SocketIOClientComponent.h

Line 457 in e6fb5db

void OnNativeEvent( const FString& EventName,

I generally recommend wrapping your multiparam into a single param as it isn't limited to function callback signature.

It seems I misunderstood, I do believe this variant:

SocketIOClient-Unreal/Source/SocketIOClient/Public/SocketIOClientComponent.h

Line 429 in e6fb5db

void EmitNative(const FString& EventName,

Does the same, but if does not, feel free to open a pull request and I can merge the feature to mainline.

[CheaterScript]

I tested the method above and didn't get the expected result:

The correct result should be:

["call","foo","bar"]

Implementing EmitMessagesWithCallback seems to be quite complex, and I'm not very proficient in C++. I'm worried that I might introduce bugs and may not be able to provide a fully functional PR.

Interesting, it does seems like the plugin is missing the implementation then. If you open a pull request with your current implementation, I'll apply patches to it to fit other methods before merging; it will give me a base scaffold to apply the rest of the functionality.
