Base64Decoder (Netty API Reference (4.1.22.Final))

java.lang.Object
- io.netty.channel.ChannelHandlerAdapter
- - io.netty.channel.ChannelInboundHandlerAdapter
  - - io.netty.handler.codec.MessageToMessageDecoder<ByteBuf>
    - - io.netty.handler.codec.base64.Base64Decoder

All Implemented Interfaces:: ChannelHandler ， ChannelInboundHandler

@ChannelHandler.Sharable
public class Base64Decoder
extends MessageToMessageDecoder<ByteBuf>

将Base64编码的ByteBuf或US-ASCII String为ByteBuf 。请注意，如果您正在使用基于流的传输（如TCP / IP），则必须使用此解码器ByteToMessageDecoder ，如DelimiterBasedFrameDecoder 。 TCP / IP的典型解码器设置为：

  ChannelPipeline pipeline = ...;

 // Decoders
 pipeline.addLast("frameDecoder", new DelimiterBasedFrameDecoder(80, Delimiters.nulDelimiter()));
 pipeline.addLast("base64Decoder", new Base64Decoder());

 // Encoder
 pipeline.addLast("base64Encoder", new Base64Encoder());
