Examples with Connection reactor.netty.Connection used on opensource projects

Example 1 with Connection

use of reactor.netty.Connection in project spring-framework by spring-projects.

the class ReactorServerHttpRequest method initSslInfo.

@Override
@Nullable
protected SslInfo initSslInfo() {
    Channel channel = ((Connection) this.request).channel();
    SslHandler sslHandler = channel.pipeline().get(SslHandler.class);
    if (sslHandler == null && channel.parent() != null) {
        // HTTP/2
        sslHandler = channel.parent().pipeline().get(SslHandler.class);
    }
    if (sslHandler != null) {
        SSLSession session = sslHandler.engine().getSession();
        return new DefaultSslInfo(session);
    }
    return null;
}
