FastNet C++/Python 网络通信库之协议

协议可以使用的基础数据类型：

UInt8,UInt16,UInt32,UInt64
Int8,Int16,Int32,Int64
Float,Double,Bool,String

[T] 数组，T代表元素类型
[K,V] 字典，K代表键，V代表值，注意键只能为基础类型。

以及三种不同的协议类型类型：

Message　　和protobuf的message类似一个Message就代表一个协议，Message可以包含Struct和Enum，可以包含基础数据类型

Struct　　结构体，和Message的区别就是结构体只能包含基础数据类型和枚举（Enum），还有就是结构体在生成代码时不会生成相关的协议ID部分代码，因为Struct就是被设计为被嵌入到其他Message当中。

Enum　　枚举，只能包含整数

支持默认值（直接在类型后面加上双括号以及变量值）

下面是协议的一个例子：

from GenProto import *
 
class DemoEnum(Enum):
    one = 1
    two = 2

class DemoStruct(Struct):
    u8 = UInt8
    u16 = UInt16
    u32 = UInt32
    u64 = UInt64
    i8 = Int8
    i16 = Int16(1111)
    i32 = Int32
    i64 = Int64(1000000000000)
    f = Float
    d = Double
    b = Bool(True)
    s = String('defVal')
    de = DemoEnum(DemoEnum.two)

class DemoMessage(Message):
    u8 = UInt8(255)
    u16 = UInt16
    u32 = UInt32
    u64 = UInt64
    i8 = Int8(-127)
    i16 = Int16
    i32 = Int32
    i64 = Int64
    f = Float(0.234234)
    d = Double
    b = Bool
    s = String
    de = DemoEnum(DemoEnum.one)
    ds = DemoStruct
    arr = [DemoStruct]
    arr2 = [String]
    dict2 = [String,DemoStruct]
    dict3 = [UInt32,String]

下面是经过协议工具生成的C++/Python结构体：

  2 #include "FastNet/core/ClassFactory.h"
  3 #include "FastNet/core/Stream.h"
  4 #include "FastNet/core/App.h"

使用(Python)：

m = FastNet.Message.Create(demo.DemoMessage.sClsId)
m.u8 = 255
m.u16 = 65535
...

session.SendMsg(m)

使用(C++)：

auto m = FastNet::Message::Create<demo::DemoMessage>();
m->u8 = 255;
m->u16 = 65535;
...

session->SendMsg(m);
