紅寶石1.9.3簡單的GET請求，麒麟通過插座

Question

現在我嘗試連接到我的插座由麒麟cretaed與此代碼

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 

但總是得到一個「HTTP/1.1 400錯誤的請求」

請，任何機構可以說我做錯了嗎？

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

這是非常有用的，但請注意的Net :: HTTP＃exec方法標記僅供內部使用。可能是因爲它沒有做資源管理等

以下工作相適應的建議的戰略覆蓋的Net :: HTTP＃連接（連接到插座）。我喜歡使用HTTParty gem來處理我的HTTP請求。所以這裏的策略使用了一個用於HTTParty的自定義ConnectionAdaptor。現在，我只需更改我的包含類中的:: default_params = call，以控制我們是使用Unix還是TCP/HTTP套接字。
