【问题描述】：

我已经编写了一个代码以在 Ruby 中接收 TCP 请求，但我无法获取即将到来的请求的 IP 地址。
我的代码如下：

 require 'socket'
puts "Starting the Server..................."
server = TCPServer.new 53492 # Server bound to port 53492
loop do
  Thread.start(server.accept) do |client|
    # client = server.accept # Wait for a client to connect
    # client.puts "Hello you are there!"
    result = ''
    ansiString = client.recv(100).chomp
    p "String = #{ansiString}"
   begin
  #  How to get the request IP adress here
    rescue Errno::EPIPE
      puts "Connection broke!"
    end
  end
end

【解决方案1】：

见IPSocket#peeraddr。

p client.peeraddr(false)[3]

或者更清楚一点：

address_family, port, hostname, numeric_address = client.peeraddr(false)
p numeric_address

【解决方案2】：

require 'socket'
puts "Starting the Server..................."
server = TCPServer.new 53492 # Server bound to port 53492
loop do
  Thread.start(server.accept) do |client|
    # client = server.accept # Wait for a client to connect
    # client.puts "Hello you are there!"
    p "Client address = #{client.peeraddr[3]}"  ## Answer
    result = ''
    ansiString = client.recv(100).chomp
    p "String = #{ansiString}"
   begin
  #  How to get the request IP adress here
    rescue Errno::EPIPE
      puts "Connection broke!"
    end
  end
end
