Ruby - Send GET request with headers

Question

I am trying to use ruby with a website\'s api. The instructions are to send a GET request with a header. These are the instructions from the website and the example php code

Answer 1

Using net/http as suggested by the question.

References:

• Net::HTTP https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP.html
• Net::HTTP::get https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP.html#method-c-get
• Setting headers: https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP.html#class-Net::HTTP-label-Setting+Headers
• Net::HTTP::Get https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP/Get.html
• Net::HTTPGenericRequest https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTPGenericRequest.html and Net::HTTPHeader https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTPHeader.html (for methods that you can call on Net::HTTP::Get)

So, for example:

require 'net/http'    

uri = URI("http://www.ruby-lang.org")
req = Net::HTTP::Get.new(uri)
req['some_header'] = "some_val"

res = Net::HTTP.start(uri.hostname, uri.port) {|http|
  http.request(req)
}

puts res.body #  ...  => nil

Note: if your response has HTTP result state 301 (Moved permanently), see Ruby Net::HTTP - following 301 redirects
