Ruby TCPSocket/HTTP请求 [英] Ruby TCPSocket / HTTP request

问题描述

我刚开始使用TCPSockets.我只是想获得Google主页.这是我的代码:

I just started with TCPSockets. I am simply trying to get the google home page. This is my code:

require 'socket'

host = 'http://www.google.com'
port = 80

s = TCPSocket.open host, port
s.puts "GET / HTTP/1.1\r\n"
s.puts "Host: Firefox"
s.puts "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
s.puts "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"
s.puts "\r\n"

while line = s.gets
  puts line.chop
end


s.close

这将返回:

HTTP/1.1 302 Document has moved
Location: http://92.242.140.29/?nxdomain=http%3A%2F%2Ffirefox&AddInType=2&PlatformInfo=pbrgen

为什么?我的目标是获取Google主页的内容.谢谢
