Output Raw HTTP Request without Sending in Ruby

Question

I am trying to setup a POST request to a rest api using ruby. What I want to do is to output the raw HTTP request without actually sending the request. I have looked at HTTParty and Net:HTTP, but it seems the only way to output the request is only once you send the request. So basically I want a convenient way for creating an HTTP request string without actually having to send it.

if you are trying to make this for testing 3rd party service... and you want to mock this request (not sending the actual request to the 3rd party service but generate a response for this request locally) ... then i urge you to check https://github.com/bblimke/webmock — a14m, Mar 08 '14 at 23:16

The HTTParty.get and similar methods methods are helper functions that wraps a lot of the internal complexity; you should just peek inside the method to find that HTTParty.get to find that inside it it just makes a call to perform_request:

def get(path, options={}, &block)
  perform_request Net::HTTP::Get, path, options, &block
end

and peeking into perform_request, we get that it just constructs a Request object and call perform on it:

def perform_request(http_method, path, options, &block) #:nodoc:
  options = default_options.merge(options)
  process_headers(options)
  process_cookies(options)
  Request.new(http_method, path, options).perform(&block)
end

You should take a look into the Request class.

Thanks for the answer. Already tried that, but internally in the Request class the method to create the request is private (setup_raw_request). I could open the class and change somethings, but that wouldn't be the ideal elegant solution I am looking for. — Wahaj Ali, Mar 09 '14 at 07:54

Take a look at Typhoeus

request = Typhoeus::Request.new(
  "www.example.com",
  method: :post,
  body: "this is a request body",
  params: { field1: "a field" },
  headers: { Accept: "text/html" }
)

It allows you to create the request and then you can run it or not with

 request.run
