C ++和Python之间的简单IPC（跨平台） [英] Simple IPC between C++ and Python (cross platform)

问题描述

我有一个在后台运行的C ++进程，会在同一个框架上运行的Python进程很少产生'事件'。

I have a C++ process running in the background that will be generating 'events' infrequently that a Python process running on the same box will need to pick up.

• C侧的代码需要尽可能轻量级。


• Python端是只读的。


• 实施必须跨平台。


• 发送的数据非常简单。

• The code on the C side needs to be as lightweight as possible.
• The Python side is read-only.
• The implementation must be cross-platform.
• The data being sent is very simple.

我的选项是什么？

感谢

推荐答案

zeromq - 没有别的。将消息编码为字符串。

zeromq -- and nothing else. encode the messages as strings.

但是，如果要从库中获取序列化，请使用 protobuf 它会为Python和C ++生成类。你在两端使用SerializeToString（）和ParseFromString（）函数，然后通过ZeroMq管道字符串。

However, If you want to get serialiazation from a library use protobuf it will generate classes for Python and C++. You use the SerializeToString() and ParseFromString() functions on either end, and then pipe the strings via ZeroMq.

问题解决，因为我怀疑任何其他解决方案更快，

Problem solved, as I doubt any other solution is faster, and neither will any other solution be as easy to wire-up and simple to understand.

如果想对rpc使用特定的系统原语，如Windows和Unix上的命名管道Unix上的域套接字，那么您应该查看 Boost :: ASIO 。然而，除非你有（a）网络背景，（b）非常好地了解C ++，这将是非常耗时的

If want to use specific system primitives for rpc such as named pipes on Windows and Unix Domain Sockets on unix then you should look at Boost::ASIO. However, unless you have (a) a networking background, and (b) a very good understanding of C++, this will be very time consuming
