从 C++ 发送数据的最佳方式编程到 Rails 服务器
我有一个 C++ 程序，它不断生成大量需要发送到 Rails 服务器的数据。程序和服务器都在运行 Suse Linux 的同一台机器上。
最有效、最简单的解决方案是什么？
I have a C++ program that is constantly generating a large amount of data that needs to be sent to a Rails server. Both the program and the server are on the same machine running Suse Linux.
What is the most efficient and simple solution for this?

套接字是必经之路。如果你想要一些好的 C++ 异步和跨平台套接字，你最好的选择可能是 boost::asio。
Sockets are the way to go. If you want some good asynchronous and cross-platform sockets in C++ your best bet, probably, will be boost::asio.
您可以按照您想要的方式存储数据（文件或数据库）。
唯一的难点是让您的 Rails 应用程序知道 C++ 程序已完成。
我强烈建议您将此信息存储在缓存中，这样每次需要时检查此信息就不会花费太多。
You could store the data the way you want (file or database).
The only tough point is to make your Rails app aware the C++ program is completed.
I'd strongly advise you to store this information in cache so that it won't cost much to check this every period you need.
您可以使用套接字，因为您的两个程序都驻留在同一台本地计算机上，并且通常通过本地套接字发送序列化数据应该非常简单。由于套接字使用内部缓冲区，因此传输时间应该非常快。您的 C++ 程序可以将数据推送到 Rails 服务器，也可以让 Rails 服务器轮询 C++ 程序，前提是您在 C++ 程序中设置缓存以在轮询调用之间存储数据。不过，推送方法可能效果最好。
You could use sockets since both your programs are residing on the same local machine, and in general it should be pretty straight-forward to send the serialized data over a local socket. Since the socket is using an internal buffer, the transfer time should be very fast. Your C++ program can either push data to the Rails server, or you can have the Rails server poll the C++ program providing you're setting up a cache in your C++ program to store the data in between polling calls. The push method would probably work best though.
