[Plugin] Socket.io Client

We are getting issues while trying to connect to our Socket.IO api.

Basically the only log we recieve from the socket is this:

SocketIOLog: SocketIO Invalid appears to have lost connection, reconnecting attempt 0 with delay 5000

.

This is despite the not getting a connection started in the first place.

I have changed the sio_client_impl.h & cpp files to use TLS by adding this line

#define SIO_TLS 1

as well as adding “OpenSSL” to the private and public dependency modules of SocketIOLib.Buid file. Had to fix some compilation errors but everything builds fine now.

This is what my connection code looks like:

TSharedPtr<FJsonObject> QueryParams = MakeShareable(new FJsonObject);
QueryParams->SetStringField("token", TokenForPlay);

Socket->VerboseLog = true;
Socket->Connect(FString(Base_URL + "/play"), QueryParams, nullptr);

Socket->OnConnectedCallback = [this](const FString& InSessionId)
{
Log(2, "Connected", Info);
};

Our socket lives under the resouce /play (https://api.xxxxx.com/play). I’ve tried every different configuration(joining the /play namespace, only using the base url etc. ) that I’ve been able to come up with and nothing has worked so far. I don’t know if I’m being fooled by the log message and TLS is actually not being used. I’ve tried to look through the implementation, and I’m at my wits end.

Any help is greatly appreciated.

TLS/SSL is currently not supported, it requires some fixes in the underlying library used. See this issue for a workaround used in the past: https://github.com//socketio-client-ue4/issues/39
