描述

Is there a way to add a CustomHandler to ChannelPipeline using NettyServerBuilder ?

I initialize my GrpcNettyServer by below:

NettyServerBuilder serverBuilder = 
    NettyServerBuilder
      .forPort(config.getPort())
      .addService();
      .intercept();
      .executor();
      .build();

All I want is to get the channel from the server and add a custom handler to the channel pipeline. Does NettyServerBuilder supports that option ?

研究方向
Investigate how to add a custom ChannelHandler to the Netty pipeline in gRPC Java. Look at NettyServerBuilder and the ServerImpl classes to find where the pipeline is configured. The HAProxy protocol requires reading the proxy protocol header before the gRPC handler. Consider using a custom ServerBuilder or intercepting the channel initialization. Review existing PRs or comments in this issue for pointers. Check the Netty documentation for HAProxy support.
