reuse data from AuthorizationListener

[wangsenyan]

hi, i want to set data in AuthorizationListener then use the data in EventListener

so i don't have to decode token twice or more

what should i do ? thanks

[mylyed]

you can use the threadlocal 🤓

[wangsenyan]

well,threadlocal is unsafe in threadpool

A workaround is to use the HttpHeaders in the handshake data. It doesn't look elegant but works.

AuthorizationListener

handshakeData.getHttpHeaders().add('YOUR_TOKEN_KEY', 'TOKEN_VALUE')

EventListener

public void onData(SocketIOClient client, MessagePayload data, AckRequest ackSender) {
    // fetch token from http headers in the handshake data
    final String token = client.getHandshakeData().getHttpHeaders().get('YOUR_TOKEN_KEY');
    // ...
}
