C++ 等效于 SerializeWithLengthPrefix [英] C++ equivalent to SerializeWithLengthPrefix

问题描述

我使用协议缓冲区(protobuf-net)和套接字(TcpListener 和 TcpClient)构建了一个通信库，它工作正常，但现在一位同事需要编写一个库来使用 C++ 与我的软件进行通信.

事实证明我正在使用 Serializer.NonGeneric.SerializeWithLengthPrefix 和 Serializer.NonGeneric.TryDeserializeWithLengthPrefix.

protobuf C++ 库中是否有等价的函数?如果没有，有谁知道如何实现它，或者已经实现了共享?

解决方案

我非常不熟悉 C++ API；但是如果您首先将数据写入缓冲区，那么长度前缀本身非常简单，特别是如果您使用固定宽度的 32 位编码(而不是 base-128 可变长度).另请参阅 google-groups 论坛上的此主题.

I built a communication library using Protocol Buffers (protobuf-net) using Sockets (TcpListener and TcpClient) and it is working fine, but now a co-worker needs to write a library to communicate with my software using C++.

Turns out that I'm using the Serializer.NonGeneric.SerializeWithLengthPrefix and Serializer.NonGeneric.TryDeserializeWithLengthPrefix.

Are there equivalent functions in the protobuf C++ libraries? If not, anyone knows how to implement it, or have it implemented to share?

解决方案

I'm not hugely familiar with the C++ API; but the length prefix itself is pretty simple if you write the data to a buffer first, especially if you use the fixed-width 32-bit encoding (rather than base-128 variable-length). See also this thread on the google-groups forum.
