how do I include a header in an http request in ruby

Question

Have the below code working:

uri = URI.parse("http://www.ncdc.noaa.gov/cdo-web/api/v2/datasets/")
response = Net::HTTP.get_response(uri)

Now I also need to pass a header with this token hash in it:

token: "fjhKJFSDHKJHjfgsdfdsljh"

I cannot find any documentation on how to do this. How do I do it?

There are many gems for Ruby that will make it much easier to use HTTP than Net::HTTP. I'd recommend researching those and picking one. Net::HTTP is really for those times when nothing else already exists. — the Tin Man

get_response is a shorthand for making a request, when you need more control - do a full request yourself.

There's an example in ruby standard library here:

uri = URI.parse("http://www.ncdc.noaa.gov/cdo-web/api/v2/datasets/")
req = Net::HTTP::Get.new(uri)
req['token'] = 'fjhKJFSDHKJHjfgsdfdsljh'

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

Thanks, but doesn't that send the request twice? When you call Net::Http.new, doesn't that send a request?

@JPB no, it initialises the request, connects to server and then sends the request.

This doesn't work anymore. Probably a https (SSL) issue.

Though you surely could use Net::HTTP for this goal, gem excon allows you to do it far easier:

require 'excon'
url = 'http://www.ncdc.noaa.gov/cdo-web/api/v2/datasets/'
Excon.get(url, headers: {token: 'fjhKJFSDHKJHjfgsdfdsljh'})

That's just one of many gems which do this. httparty, Faraday and curb are also very popular.
