a brief introduction to Protobuf
Baidu Encyclopedia: Protocolbuffer (hereinafter referred to as PB) is Google's Data Interchange format, which is independent of the language, independent of the platform. Google offers implementations in multiple languages: Java, C #, C + +, go and Python, each of which contains compilers and library files for the appropriate language. Because it is a binary format, it is much faster than using XML for data exchange. It can be used in data communication between distributed applications or in heterogeneous environments. As a good efficiency and compatibility of the binary data transmission format, can be used for such as network transport, configuration files, data storage and many other areas.

two use protobuf
1 Importing third-party libraries
I directly put the protobuf third-party library in the project.


Modify the Egretproperties.json file to add the Protobuf library. After the addition is complete, the engine needs to be compiled.


2 Writing Protobuf files
Create a new file Template.proto
I'm writing a test data here, User_login


3 Loading Protobuf files

Note Type if text


4 using Protobuf
Read Template_proto file

[C + +]Plain Text view copy code ?

1	var message = dcodeIO.ProtoBuf.loadProto(RES.getRes("template_proto"));

Create a new User_login class

[AppleScript]Plain Text view copy code ?

1234	var user_login_class = message.build("user_login");var user_login = new user_login_class();user_login.userId = 123;user_login.userName = "peter";

Turn User_login into bytes

[C #]Plain Text view copy code ?

1	var bytes = user_login.toArrayBuffer();

Socket send User_login

[C #]Plain Text view copy code ?

123	var socket:egret.WebSocket = newegret.WebSocket();socket.writeBytes(bytes);socket.flush();

The processing of receiving data is roughly the same, see demo in detail.
