C++ 之间的相互作用和 Rails 应用程序

发布于 2024-08-25 02:02:27 字数 442 浏览 5 评论 0原文

我有两个应用程序：c++ 服务和 RoR Web 服务器（它们都在同一 VPS 上运行）

我需要彼此“发送”一些变量（然后对它们执行某些操作）。例如，我正在寻找这样的东西：

// my C++ sample
void SendMessage(string message) {
   SendTo("127.0.0.1", message);
}

void GetMessage(string message) {
   if (message == "stop")
      SendMessage("success");
}

# Ruby sample
# application_controller.rb

def stop
   @m = Messager.new
   @m.send("stop")
end

我以前从未使用过它，我什至不知道我应该搜索和学习哪些技术。

I have never used it before, and i even don't know which technology should i search and learn.

好的，我找到了解决方案。它的 TCP 套接字：

Ruby TCP 服务器，发送消息：

require 'socket'

server = TCPServer.open(2000)
loop {                       
  Thread.start(server.accept) do |client|
    client.puts(Time.now.ctime)
    client.puts "Closing the connection. Bye!"
    client.close               
  end

}

Ruby 客户端，接受消息：

require 'socket'

host = 'localhost'
port = 2001 # it should be running server, or it will be connection error

s = TCPSocket.open(host, port)
  while line = s.gets
    puts line.chop
  end
s.close

现在您应该在另一个应用程序中编写 TCP 服务器+客户端。但你已经明白了。

Ok, i have found the solution. Its TCP sockets:

Ruby TCP server, to send messages:

require 'socket'

server = TCPServer.open(2000)
loop {                       
  Thread.start(server.accept) do |client|
    client.puts(Time.now.ctime)
    client.puts "Closing the connection. Bye!"
    client.close               
  end

}

Ruby client, to accept messages:

require 'socket'

host = 'localhost'
port = 2001 # it should be running server, or it will be connection error

s = TCPSocket.open(host, port)
  while line = s.gets
    puts line.chop
  end
s.close

Now you should write TCP-server+client in another application. But you have got the idea.
