如何只为一个方法而不是全局设置 TCPSocket 属性？
How do I set TCPSocket attributes for only a method and not globally?
我正在使用 Rails 4.2.7 和 Ruby 2.3.0。我有通过 SOCKS 代理获取网页的代码
require "resolv-replace.rb"
require 'open-uri'
require 'uri'
require "socksify"
require 'socksify/http'
...
def get_content_via_socks(socks_server, socks_port, url, headers)
TCPSocket::socks_server = socks_server
TCPSocket::socks_port = socks_port
uri = URI(url)
res1 = Net::HTTP.SOCKSProxy(nil, nil).start(uri.host, uri.port, :use_ssl => (uri.scheme == "https")) do |http|
http.read_timeout = 500
puts "launching #{uri} on #{socks_server}:#{socks_port}"
resp = http.get(uri, initheader = headers)
end
end
唯一的问题是即使我已经设置
TCPSocket::socks_server = socks_server
TCPSocket::socks_port = socks_port
在我的本地方法中，它似乎影响了整个应用程序。那是我打电话给
http = Net::HTTP.new(uri.host, uri.port)
从另一个方法，它失败，除非上面的socks_server和socks_port是运行。如何仅为该方法设置 socks_server 和 socks_port 而不影响应用程序的其余部分？请不要在这里说设置参数
res1 = Net::HTTP.SOCKSProxy(nil, nil)
这些参数没有意义。您可以将它们设置为 "abc" 和 "def"，它们的行为与将它们设置为有效值时的行为完全相同。

备注
Please don't say set the parameters here
res1 = Net::HTTP.SOCKSProxy(nil, nil)
抱歉，我不得不说您应该设置这些参数。 :)
在设置 TCPSocket::socks_server 时我无法让你的示例工作，但在使用 Net::HTTP.SOCKSProxy(socks_server, socks_port) 时它工作得很好。
我用过：
$ ruby -v && gem list socksify
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]
*** LOCAL GEMS ***
socksify (1.7.0)
设置
在 linux 客户端上，我使用这些命令连接到两个 linux 服务器，同时在 2 个不同的终端中：
ssh -D 1085 linux_server1 -N
ssh -D 1084 linux_server2 -N
我的客户端现在有 2 个 Socks 代理，运行 在端口 1084 和 1085 上。
测试
这些方法连接到 [http://whatismyip.akamai.com][1] 以检查是否正在使用 SOCKS 代理。
require 'socket'
require 'socksify'
require 'socksify/http'
require 'uri'
require 'net/http'
def translate_ips(str)
my_ips = {
"XXX.XXX.XXX.XXX" => 'local_ip :(',
"YYY.YYY.YYY.YYY" => 'socks_ip1 :D',
"ZZZ.ZZZ.ZZZ.ZZZ" => 'socks_ip2 :D'
}
str.gsub(/\d{1,3}\.\d{1,3}\.\d{1,3}.\d{1,3}/,my_ips)
end
def get_content_via_socks_v1(socks_server, socks_port, url, headers)
TCPSocket::socks_server = socks_server
TCPSocket::socks_port = socks_port
uri = URI(url)
res1 = Net::HTTP.SOCKSProxy(nil, nil).start(uri.host, uri.port, :use_ssl => (uri.scheme == "https")) do |http|
http.read_timeout = 500
puts "launching #{uri} on #{socks_server}:#{socks_port}"
resp = http.get(uri, initheader = headers)
end
end
def get_content_via_socks_v2(socks_server, socks_port, url, headers)
uri = URI(url)
Net::HTTP.SOCKSProxy(socks_server, socks_port).start(uri.host, uri.port, use_ssl: (uri.scheme == 'https')) do |http|
http.read_timeout = 500
puts "launching #{uri} on #{socks_server}:#{socks_port}"
http.get(uri, headers)
end
end
puts translate_ips(get_content_via_socks_v1('localhost', 1085, 'http://whatismyip.akamai.com', nil).body)
puts translate_ips(get_content_via_socks_v1('localhost', 1084, 'http://whatismyip.akamai.com', nil).body)
puts
puts translate_ips(get_content_via_socks_v2('localhost', 1085, 'http://whatismyip.akamai.com', nil).body)
puts translate_ips(get_content_via_socks_v2('localhost', 1084, 'http://whatismyip.akamai.com', nil).body)
它输出：
launching http://whatismyip.akamai.com on localhost:1085
local_ip :(
launching http://whatismyip.akamai.com on localhost:1084
local_ip :(
launching http://whatismyip.akamai.com on localhost:1085
socks_ip1 :D
launching http://whatismyip.akamai.com on localhost:1084
socks_ip2 :D
Net::HTTP.SOCKSProxy(socks_server, socks_port) 版本工作得很好！
如果我尝试使用 Net::HTTP.SOCKSProxy("bogus", "bogus")，该方法会引发异常：
in `rescue in block in connect': Failed to open TCP connection to whatismyip.akamai.com:80 (getaddrinfo: Servname not supported for ai_socktype) (SocketError)
多线程
在方法的开头设置 TCPSocket::socks_server 不是线程安全的。
将 Net::HTTP.SOCKSProxy 与块一起使用应该可以防止竞争条件：
threads = []
10.times do
sleep 0.1
threads << Thread.new { puts translate_ips(get_content_via_socks_v2('localhost', 1085, 'http://whatismyip.akamai.com', nil).body)}
threads << Thread.new { puts translate_ips(get_content_via_socks_v2('localhost', 1084, 'http://whatismyip.akamai.com', nil).body)}
end
threads.join
它输出：
launching http://whatismyip.akamai.com on localhost:1084
socks_ip2 :D
launching http://whatismyip.akamai.com on localhost:1085
socks_ip1 :D
launching http://whatismyip.akamai.com on localhost:1084

Net::HTTP.SOCKSProxy(socks_server, socks_port) 版本工作得很好！
如果我尝试使用 Net::HTTP.SOCKSProxy("bogus", "bogus")，该方法会引发异常：
in `rescue in block in connect': Failed to open TCP connection to whatismyip.akamai.com:80 (getaddrinfo: Servname not supported for ai_socktype) (SocketError)
多线程
在方法的开头设置 TCPSocket::socks_server 不是线程安全的。
将 Net::HTTP.SOCKSProxy 与块一起使用应该可以防止竞争条件：
threads = []
10.times do
sleep 0.1
threads << Thread.new { puts translate_ips(get_content_via_socks_v2('localhost', 1085, 'http://whatismyip.akamai.com', nil).body)}
threads << Thread.new { puts translate_ips(get_content_via_socks_v2('localhost', 1084, 'http://whatismyip.akamai.com', nil).body)}
end
threads.join
它输出：
