Getting string from netty ByteBuf
提问by aries
How can I get the string from a netty ByteBuf? As of now I am able to get it character by character. Is there a way to get the string object directly?
如何从 netty 获取字符串ByteBuf？到目前为止，我可以逐个字符地获取它。有没有办法直接获取字符串对象？
// message is of type ByteBuf
for (int i = 0; i < message.capacity(); i++) {
byte b = message.payload().getByte(i);
System.out.print((char) b);
}

Use the provided method ByteBuf.toString(Charset) .
使用提供的方法ByteBuf.toString(Charset)。

use ByteBuf.readCharSequence()
利用 ByteBuf.readCharSequence()
example is here:
例子在这里：
// here we use utf-8 decoding, you can choose the charset you want
String s = ByteBuf.readCharSequence(length, Charset.forName("utf-8")).toString()
note that ByteBuf.readCharSequence()returns java.lang.CharSequence, use toString()to get Stringobejct
请注意，ByteBuf.readCharSequence()返回java.lang.CharSequence，用于toString()获取String对象

From there you can use new String(byte[])or some Base64 solution (since it's binary data I'm assuming)
从那里你可以使用new String(byte[])或一些 Base64 解决方案（因为它是我假设的二进制数据）
