Ruby Proxy Authentication GET/POST with OpenURI or net/http

Question

I'm using ruby 1.9.3 and trying to use `open-uri` to get a url and try posting using `Net:HTTP` Im trying to use proxy authentication for both: Trying to do a `POST` request with `net/http`: ``` require 'net/http' require 'open-uri' http = Net::HTTP.new("google.com", 80) headers = { 'User-Agent' => 'Ruby 193'} resp, data = http.post("/", "name1=value1&name2=value2", headers) puts data ``` And for `open-uri` which I can't get to do `POST` I use: ``` data = open("http://google.com/","User-Agent"=> "Ruby 193").read ``` How would I modify these to use a proxy with HTTP Authentication I've tried (for open-uri) ``` data = open("http://google.com/","User-Agent"=> "Ruby 193", :proxy_http_basic_authentication => ["http://proxy.com:8000/", "proxy-user", "proxy-password"]).read ``` However all I will get is a `OpenURI::HTTPError: 407 Proxy Authentication Required`. I've verified all and it works in the browser with the same authentication and proxy details but I can't get ruby to do it. How woul…

Accepted Answer

Try:

```
require "open-uri"
proxy_uri = URI.parse("http://proxy.com:8000")

data = open("http://www.whatismyipaddress.com/", :proxy_http_basic_authentication => [proxy_uri, "username", "password"]).read
puts data
```

As for Net::HTTP, I recently implemented support for proxies with http authentication into a Net::HTTP wrapper library called http. If you look at my last pull-request, you'll see the basic implementation.

EDIT: Hopefully this will get you moving in the right direction.

```
Net::HTTP::Proxy(proxy_uri.host, proxy_uri.port,"username","password").start('whatismyipaddress.com') do |http| 
  puts http.get('/').body
end
```

EDIT 11/24/2020: `Net::HTTP::Proxy` is now considered obsolete. You can now configure proxies when creating a new instance of `Net::HTTP`. See the documentation for Net::HTTP.new for more details.
