我正在尝试设置代理并在文档中的简单获取请求中使用它。但我总是收到错误消息!地址和端口对 open-uri 是正确的,它可以工作.. 它是 http://proxy:8080.

proxy_addr = 'proxy'
proxy_port = 8080

Net::HTTP.new('google.de', nil, proxy_addr, proxy_port).start { |http|
  # always proxy via your.proxy.addr:8080
  Net::HTTP.get('google.de', '')
}

我究竟做错了什么?感谢所有答案!

还有另一种选择:

Net::HTTP 将自动从http_proxy 环境变量创建一个代理(如果存在)。

所以你可以使用

ENV['http_proxy'] = 'http://172.16.3.160:4226' # your http://address:port here

Net::HTTP 默认将其用于所有请求。

它对第三方库中的 net_http 请求很有帮助(例如它适用于MailChimp的 gem gibbon)。

传递nil代理地址以禁用默认值http_proxy

Net::HTTP.new('google.de', nil, proxy_addr, proxy_port).start { |http|

这将创建一个http对象供您在块中使用。在这里使用它而不是每次都生成新的Net::HTTP.get('google.de', '')

proxy_addr = 'proxy'
proxy_port = 8080

Net::HTTP.new('google.de', nil, proxy_addr, proxy_port).start { |http|
  # always proxy via your.proxy.addr:8080
  http.get('google.de', '')
}

如果您在代理后面进行 REST api 调用,以下是有效的代码:

require "uri"
require 'net/http'
    
proxy_host = '<proxy addr>'
proxy_port = '<proxy_port'
proxy_user = '<username>'
proxy_pass = '<password>'
    
uri   = URI.parse("https://saucelabs.com:80/rest/v1/users/<username>")
proxy = Net::HTTP::Proxy(proxy_host,
                         proxy_port,
                         proxy_user,
                         proxy_pass)
    
req = Net::HTTP::Get.new(uri.path)

req.basic_auth(<sauce_username>,
               <sauce_password>)
    
result = proxy.start(uri.host,uri.port) do |http|
  http.request(req)
end
    
puts result.body
