Class ServerAclHandler

  • All Implemented Interfaces:
    io.grpc.ServerInterceptor, io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
    @Sharable
public class ServerAclHandler
extends io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http.HttpRequest>
implements io.grpc.ServerInterceptor
    Together with ServerStoreAclHandler, Server will allow two kinds of access pattern: 1. Access from Router, and Router request will be validated in ServerAclHandler, and ServerStoreAclHandler will be a quick pass-through. 2. Access from Client directly, and ServerAclHandler will deny the request, and ServerStoreAclHandler will validate the request in store-level, which is exactly same as the access control behavior in Router. If both of them fail, the request will be rejected.
