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 they give. I am to calculate a HMAC hash and include it under an apisign header.
$apikey='xxx';
$apisecret='xxx';
$nonce=time();
$uri='
$sign=hash_hmac('sha512',$uri,$apisecret);
$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:'.$sign));
$execResult = curl_exec($ch);
$obj = json_decode($execResult);
I am simply using an .rb file with ruby installed on windows from command prompt. I am using net/http in the ruby file. How can I send a GET request with a header and print the response?

Using net/http as suggested by the question.
References:
Net::HTTPNet::HTTP::get- Setting headers:
Net::HTTP::GetNet::HTTPGenericRequestandNet::HTTPHeader(for methods that you can call onNet::HTTP::Get)
So, for example:
require 'net/http'
uri = URI("")
req = Net::HTTP::Get.new(uri)
req['some_header'] = "some_val"
res = Net::HTTP.start(uri.hostname, uri.port, use_ssl: uri.scheme == 'https') { |http|
http.request(req)
}
puts res.body # <!DOCTYPE html> ... </html> => nil
Note: if your response has HTTP result state 301 (Moved permanently), see Ruby Net::HTTP - following 301 redirects
Install httparty gem, it makes requests way easier, then in your script
require 'httparty'
url = '
headers = {
key1: 'value1',
key2: 'value2'
}
response = HTTParty.get(url, headers: headers)
puts response.body
then run your .rb file..
As of Ruby 3.0, Net::HTTP.get_response supports an optional hash for headers:
Net::HTTP.get_response(URI('), { 'Accept' => 'text/html' })
Unfortunately this does not work for Ruby 2 (up to 2.7).
