类 HuluRpcProtocol

java.lang.Object

com.baidu.brpc.protocol.AbstractProtocol

com.baidu.brpc.protocol.hulu.HuluRpcProtocol

所有已实现的接口:

Protocol

public class HuluRpcProtocol
extends AbstractProtocol

Notes on HULU PBRPC Protocol:

• Header format is ["HULU"][body_size][meta_size ], 12 bytes in total
• body_size and meta_size are NOT in network byte order (little endian)
• Use service->name() and method_index to identify the service and method to call
• user_message_size is set iff request/response has attachment
• The following fields of rpc are not supported yet:
  • chunk_info

方法详细资料

encodeRequest

public io.netty.buffer.ByteBuf encodeRequest(Request request)
                                      throws Exception

从接口复制的说明: Protocol

客户端序列化请求对象

参数:

request - 待发送给服务端的对象

抛出:

Exception - 序列化异常

decodeResponse

public Response decodeResponse(Object packet,
                               io.netty.channel.ChannelHandlerContext ctx)
                        throws Exception

从接口复制的说明: Protocol

客户端反序列化rpc响应

参数:

packet - header & body的buf

ctx - netty channel context

抛出:

Exception - 反序列化异常

decodeRequest

public Request decodeRequest(Object packet)
                      throws Exception

从接口复制的说明: Protocol

服务端反序列化rpc请求

参数:

packet - header & body的buf

抛出:

Exception

encodeResponse

public io.netty.buffer.ByteBuf encodeResponse(Request request,
                                              Response response)
                                       throws Exception

从接口复制的说明: Protocol

服务端序列化返回结果。

response - 服务端要返回给客户端的对象

抛出:

Exception - 序列化异常

encode

protected io.netty.buffer.ByteBuf encode(HuluRpcEncodePacket packet)
                                  throws IOException

抛出:

IOException

decode

public HuluRpcDecodePacket decode(io.netty.channel.ChannelHandlerContext ctx,
                                  DynamicCompositeByteBuf in,
                                  boolean isDecodingRequest)
                           throws BadSchemaException,
                                  TooBigDataException,
                                  NotEnoughDataException

从接口复制的说明: Protocol

客户端/服务端解析请求包成header+body buffer

in - 输入byte buf

返回:

header+body buffer

抛出:

BadSchemaException - header格式不对

TooBigDataException - body太大

NotEnoughDataException - 可读长度不够，由于粘包拆包问题。

isCoexistence

public boolean isCoexistence()

从接口复制的说明: Protocol

该协议是否可以和其他协议共存。

指定者:

isCoexistence 在接口中 Protocol

覆盖:

isCoexistence 在类中 AbstractProtocol

返回:

true可以共存，false不能共存。
