php/c++ - PHP 和 C 之间通信的最佳方法客户端（REST、套接字等）
假设我有一个用 PHP 编写的网站。用户从网站下载 C++ 控制台程序并将其安装在计算机上。现在，我希望能够将 printf() 字符串从我的 PHP 网站（服务器）打印到 C++ 控制台程序（客户端）。我想过通过提供 XML 文件来使用 REST，例如：
<prints> <print>Text</print> </prints>
REST 的优点是它易于使用。缺点是C++程序必须不断下载XML文件。如果用户的互联网使用受到限制，这会是一个问题吗？
另一种解决方案是套接字，它可以消除上述问题，但是它们更复杂，并且可能会被防火墙/路由器阻止。
我的问题是：如果用户的互联网使用受到限制，从 Web 服务器下载 XML 文件是否会产生问题？另外，REST 和套接字之间是否存在折衷方案，或者是否有这种类型的通信的替代方案？
Let's say I have a website written in PHP. A user downloads a C++ console program from the website and installs it on their computer. Now, I want to be able to printf() strings from my PHP website (the server) to the C++ console programs (the clients). I have thought of using REST by serving XML file such as:
<prints> <print>Text</print> </prints>
The advantage of REST is it's ease of use. The disadvantage is the C++ program has to constantly download the XML file. Would this be a problem if the user has a limit on their internet usage?
Another solution is sockets which eliminate the issue above, but, they are more complicated and they may be blocked by firewalls/routers.
My question is: Will downloading the XML file from the web server create a problem if the user has a limit on their internet usage? Also, is there a compromise between REST and sockets or is there an alternative to this type of communication?
