Authentication with LiteralBasedProvider and NetworkedDataProvider

exchangepulse

I am using these two providers:

com.lightstreamer.adapters.metadata.LiteralBasedProvider
com.lightstreamer.adapters.remote.data.NetworkedDataProvider

I am building an adapter in PHP that speaks with the NetworkedDataProvider. So far everything is working out nicely, but for the life of me can't see how to enable the authentication layer. I understand how to handle the incoming packets, but I am not seeing them in the request channel. I am constantly polling the socket for new requests, but not getting any. In the JavaScript client, I have enabled auth by setting the username/password. From what I gather, authentication is delt with in the Metadata layer, but I don't see where to enable it.

Any pointers much appreciated!

Best,

Hi Erik,

You are using a remote Data Adapter and a local Metadata Adapter. To handle authentication from your PHP code you need to use a remote Metadata Adapter too.

To do that, instead of "com.lightstreamer.adapters.metadata.LiteralBasedProvider", you should use "com.lightstreamer.adapters.remote.metadata.NetworkedMetadataProvider".

For a full config file example, please see "Lightstreamer\DOCS-SDKs\sdk_adapter_remoting_infrastructure\conf\sockets" or "Lightstreamer\DOCS-SDKs\sdk_adapter_remoting_infrastructure\conf\sockets(robust)" in any Lightstreamer distribution.

Cheers,

Alessandro

Now, when you say that it makes perfect sense. I didn't think to try that.

Thanks, that works perfectly!
