Example 6 with StringEncoder

use of io.netty.handler.codec.string.StringEncoder in project netty by netty.

the class SecureChatServerInitializer method initChannel.

@Override
public void initChannel(SocketChannel ch) throws Exception {
    ChannelPipeline pipeline = ch.pipeline();
    // Add SSL handler first to encrypt and decrypt everything.
    // In this example, we use a bogus certificate in the server side
    // and accept any invalid certificates in the client side.
    // You will need something more complicated to identify both
    // and server in the real world.
    pipeline.addLast(sslCtx.newHandler(ch.alloc()));
    // On top of the SSL handler, add the text line codec.
    pipeline.addLast(new DelimiterBasedFrameDecoder(8192, Delimiters.lineDelimiter()));
    pipeline.addLast(new StringDecoder());
    pipeline.addLast(new StringEncoder());
    // and then business logic.
    pipeline.addLast(new SecureChatServerHandler());
