How to convert a netty ByteBuf to a String and vice versa

问题

Is there a way to convert a netty ByteBuf to a String and vice versa?

public String toString(ByteBuf b){

 //return b enconded to a String
}

public Bytebuf ToByteBuff(String s){

  //return s decoded to Bytebuf
}

回答1:

You can use ByteBuf.toString(Charset) to convert to string.

You can use String.getBytes(Charset) and Unpooled.wrappedBuffer(byte[]) to convert to ByteBuf.

回答2:

You can create a ByteBuf from a String with Unpooled.copiedBuffer(String, Charset).
