protobuf c tutorial

The Netty provides two encoders (Protobufencoder,protobufvarint32lengthfieldprepender) for the Protobuf, Two decoders (Protobufvarint32framedecoder,protobufdecoder)[note] The so-called encoding is to encode the data type used by the application into a binary byte stream transmitted over the network, and vice versa.Look at an example of a Netty official online that uses protobuf:Localtimeprotocol.proto file: [Java] View Plain copy print? packageorg.jbo

What is Protobuf A data storage and transmission format, used for structured data, has the advantages of compact structure, small footprint, fast structure, good expansibility, and platform and language independent. Use steps 1. Define the proto file (structure description) 2. Generate the implementation of the corresponding language (Java, etc.) 3. The data stream is generated into the proto format data Flow 4. Receiver-side Analytic data Example

Defining messages and handling with PROTOBUF (Jin Qing's column) Message definition: Package MSGPB; Message MSG { Required String type = 1; Full type name of data. Required bytes data = 2; Serialized bytes fo concrete msg. } Message Sending code: void Msgsender::send (const std::string sdest, const MSGPB::MSG MSG) { std::string s; BOOL Bsuc = Msg.
