具有非阻塞或多线程功能的 Ruby Tcp Server 类

问题描述

找不到任何有助于制作非阻塞/多线程服务器的 gem 或类.在哪里可以找到?

Can't find any gem or class which can help to made a non-blocking/multithread server. Where to find any?

推荐答案

Ruby套接字上的文档 有一些很好的例子.使用来自该页面的信息，我使用非阻塞套接字拼凑了一个简单的客户端和服务器.这些主要是该页面的代码副本，并进行了一些更改.

The Ruby docs on sockets have some pretty good examples. Using information from that page, I cobbled together a simple client and server using non-blocking sockets. These are mostly copies of code from that page with a few changes.

简单的服务器代码(带有您可能感兴趣的 accept_nonblock 调用):

The simple server code (with the accept_nonblock call that you may be interested in):

 require 'socket'
 include Socket::Constants


 socket = Socket.new(AF_INET, SOCK_STREAM, 0)
 sockaddr = Socket.sockaddr_in(6212, 'localhost')
 socket.bind(sockaddr)
 socket.listen(5)
 begin
   client_socket, client_sockaddr = socket.accept_nonblock
 rescue Errno::EAGAIN, Errno::ECONNABORTED, Errno::EINTR, Errno::EWOULDBLOCK
   IO.select([socket])
   retry
 end
 puts client_socket.readline.chomp
 client_socket.puts "hi from the server"
 client_socket.close
 socket.close

还有一个与之交谈的客户:

And a client that talks to it:

 require 'socket'
 include Socket::Constants

 socket = Socket.new(AF_INET, SOCK_STREAM, 0)
 sockaddr = Socket.sockaddr_in(6212, 'localhost')
 begin
   socket.connect_nonblock(sockaddr)
 rescue Errno::EINPROGRESS
   IO.select(nil, [socket])
   begin
     socket.connect_nonblock(sockaddr)
   rescue Errno::EINVAL
     retry
   rescue Errno::EISCONN
   end
 end
 socket.write("hi from the client\n")
 results = socket.read
 puts results
 socket.close
