2、protobuf 是什么
protobuf是google提供的一个 开源序列化框架 ，类似于XML，JSON这样的数据表示语言，其最大的特点是 基于二进制 ，因此比传统的XML 表示高效短小得多。虽然是二进制数据格式，但并没有因此变得复杂，开发人员通过按照一定的语法定义结构化的消息格式，然后送给命令行工具，工具将自动生成 相关的类，可以支持php、java、c++、python等语言环境。通过将这些类包含在项目中，可以很轻松的调用相关方法来完成业务消息的序列化与反 序列化工作。
protobuf在google中是一个比较核心的基础库，作为分布式运算涉及到大量的不同业务消息的传递，如何高效简洁的表示、操作这些业务消息在 google这样的大规模应用中是至关重要的。而protobuf这样的库正好是在效率、数据大小、易用性之间取得了很好的平衡。
简单看来 就是一个序列化和反序列化工具。

step2
使用blackboxprotobuf 对密文反序列化
[ol]
pip install blackboxprotobuf protobuf
import blackboxprotobuf
deserialize_data, message_type = blackboxprotobuf.protobuf_to_json(out_b)
print(f"原始数据: {deserialize_data}")
print(f"消息类型: {message_type}")
得到结果：
[/ol]
原始数据: {"1": "3","4": [ { "1": "138","2": "8"},{"1": "139","2": "8"},{"1": "144","2": "8"},…………]}

step3
分析源码构造message的.proto文件
[ol]
源码：
MatchPlayInfo部分
o.MatchPlayInfo = function () {
function t(t) {
if (this.stepInfoList = [], t) for (var e = Object.keys(t), o = 0; o >> 3) {
case 1:
n.gameType = t.int32();
break;
case 2:
n.mapId = t.int32();
break;
case 3:
n.mapSeed = t.int32();
break;
case 4:
n.stepInfoList && n.stepInfoList.length || (n.stepInfoList = []), n.stepInfoList.push(c.protocol.MatchStepInfo.decode(t, t.uint32()));
break;
default:
t.skipType(7 & a);
}
}
return n;
}, t;
}()
MatchStepInfo部分
o.MatchStepInfo = function () {
function t(t) {
if (t) for (var e = Object.keys(t), o = 0; o >> 3) {
case 1:
n.chessIndex = t.int32();
break;
case 2:
n.timeTag = t.int32();
break;
default:
t.skipType(7 & a);
}
}
return n;
}, t;
}()
根据源码及解析结果构建.proto文件
[/ol]
syntax = 'proto3';
message MatchPlayInfo{
int32 gameType = 1;
int32 mapId = 2;
int32 mapSeed = 3;
repeated StepInfoList stepInfoList = 4;
}
message StepInfoList{
int32 chessIndex = 1;
int32 timeTag = 2;
}
存为 yang.proto文件
step4
通过.proto文件生成对应的python代码
[ol]
pip install grpcio-tools
python -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. yang.proto
[/ol]
step5
引用 yang_pb2.py 进行加解密
