Question

现在我尝试使用此代码连接到由unicorn创建的套接字

require 'socket'

def foo
  socket = UNIXSocket.new("path_to_socket/tmp/unicorn.sock")

  data = "GET /time HTTP/1.1\n" 
  data << "Connection: Close\n" 
  data << "User-Agent: Mozilla/5.0\n" 
  data << "Accept: */*\n" 
  data << "Content-Type: application/x-www-form-urlencoded\n" 
  data << "\n\r\n\r"

  socket.puts(data)

  while(line = socket.gets) do
    puts line
  end 
end

foo

但总是得到“HTTP / 1.1 400 Bad Request”

拜托，任何人都能说出我做错了吗？

Answer 1

使用net / http ...

require "net/http"
require "socket"

sock = Net::BufferedIO.new(UNIXSocket.new("path_to_socket/tmp/unicorn.sock"))
request = Net::HTTP::Get.new("/time")
request.exec(sock, "1.1", "/time")

begin
  response = Net::HTTPResponse.read_new(sock)
end while response.kind_of?(Net::HTTPContinue)
response.reading_body(sock, request.response_body_permitted?) { }

response.body
response.code

这非常有用，但请注意，Net :: HTTP #exec方法标记为仅供内部使用。可能因为它没有进行资源管理等等。

以下工作调整建议的策略以覆盖Net :: HTTP＃connect（连接到套接字）。我喜欢使用HTTParty gem来处理我的HTTP请求。因此，此处的策略使用了针对HTTParty的自定义ConnectionAdaptor。现在我可以在我的包含类上更改:: default_params =调用，以控制我们是使用Unix还是TCP / HTTP套接字。
