For TLS connections, how can I set TLSSettings? about mqtt-hs HOT 6 CLOSED

I added _tlsSettings :: TLSSettings to the MQTTConfig type and plumbed that through for both mqtts:// and wss:// connections. It's TLSSettings so you should be able to either a simple or full set of settings to configure the TLS bits of your client.

Let me know how this works!

For those, inexperienced like me, you need to populate ClientHooks with appropriate onCertificateRequest and onServerCertificate functions like here: https://stackoverflow.com/a/40082394/1663197.

Hmm... I was wondering how this might work, but haven't needed it myself. It's definitely something I need to consider.

I may need to abstract TLS settings in such a way I can supply TLS settings for both mqtts and wss since doing it from the URI is kind of hard.

In the meantime, I did expose the lower-level conduit mechanism. mqtts translates approximately torunClientTLS which is implemented like this:

-- | Set up and run a client connected via TLS.
runClientTLS :: MQTTConfig -> IO MQTTClient
runClientTLS cfg@MQTTConfig{..} = tcpCompat (runTLSClient (tlsClientConfig _port (BCS.pack _hostname))) cfg

-- Compatibility mechanisms for TCP Conduit bits.
tcpCompat :: ((AppData -> IO ()) -> IO ()) -> MQTTConfig -> IO MQTTClient
tcpCompat mkconn = runMQTTConduit (adapt mkconn)
  where adapt mk f = mk (f . adaptor)
        adaptor ad = (appSource ad, appSink ad)

I filed snoyberg/conduit/issues/423 for this. I don't see how I'd actually supply this to the underlying conduit TLS connector.

I figured you could use the TLSClientConfig constructor instead of the tlsClientConfig helper method

Can confirm this works as expected. Thanks!
