encode(ChannelHandlerContext ctx, CharSequence msg, List<Object> out):将字符序列消息编码为字节。这个方法重写了MessageToMessageEncoder接口的encode方法。 在编码过程中,首先检查字符序列是否为空,如果为空,则直接返回。 使用ByteBufUtil.encodeString方法将字符序列编码为字节,并使用ctx.alloc()分配内存缓冲区。

前面我们提到了 unicode bytecode 通常是无法被直接存储到磁盘的,所以当我们输入一个 unicode string 并且期望存储时,首相要将 unicode string encode 为 utf-8 等编码格式,然后在读取时,再重新 decode 为 unicode string,保持其格式的一致性,避免程序出错。 >>> c_char = u'一' # 赋值 unicode string >>> ...
Let’s look at a simple example of python string encode() decode() functions. str_original = 'Hello' bytes_encoded = str_original.encode(encoding='utf-8') print(type(bytes_encoded)) str_decoded = bytes_encoded.decode() print(type(str_decoded)) print('Encoded bytes =', bytes_encoded)...

decode()方法为bytes对象的方法,用于将二进制数据转换为字符串,即将使用encode()方法转换的结果再转换为字符串就是解码。 其语法格式为bytes.decode(encoding="utf-8", errors="strict") 参数说明如下: bytes:表示要进行转换的二进制数据,通常是encode()方法转换的结果。
