How to set a proxy in rubys net/http?
提问by ada91
I'm trying to set a proxy and to use it in a simple get request like in the documentation.
But I always receive an error!
The adress and port are right with open-uri it worked.. it's
http://proxy:8080.
我正在尝试设置代理并在文档中这样的简单获取请求中使用它。但我总是收到一个错误！地址和端口与 open-uri 是正确的，它起作用了..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', '')
}
What am I doing wrong? Thanks for all answers!
我究竟做错了什么？感谢所有的答案！

Net::HTTP.new('google.de', nil, proxy_addr, proxy_port).start { |http|
This will create an httpobject for you to use in the block. Use that rather than generating new ones each time, here Net::HTTP.get('google.de', '')
这将创建一个http对象供您在块中使用。使用它而不是每次都生成新的，在这里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', '')
}

There is another option:
还有另一种选择：
Net::HTTP will automatically create a proxy from the http_proxyenvironment variable if it is present.
http_proxy如果环境变量存在，Net::HTTP 将自动从环境变量创建代理。
So you can use
所以你可以使用
ENV['http_proxy'] = 'http://172.16.3.160:4226' # your http://address:port here
and Net::HTTP will use it for all requests by default.
默认情况下，Net::HTTP 将对所有请求使用它。
It can be helpful for net_http requests in third-party libraries (for example it works for gem gibbonfor MailChimp).
它可以是在第三方库net_http请求（例如，它适用于创业板有帮助长臂猿为MailChimp）。
Pass nilfor the proxy address to disable default http_proxy.
通过nil为代理地址禁用默认http_proxy。

Here is the code that works if you are making a REST api call behind a proxy:
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
