(Ruby) Duplicate curl -u user:password with Chilkat HTTP

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

#  It requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()
req = Chilkat::CkHttpRequest.new()

#  The AddHeader method corresponds to the curl "-H" argument.
req.AddHeader("Accept","application/json")
req.AddHeader("Accept-Language","en_US")

#  The curl "-d" argument specifies the HTTP request body.  In this case,
#  we're sending an application/x-www-form-urlencoded request, and therefore
#  the body contains the URL-encoded query parameters.
req.AddParam("grant_type","client_credentials")

http.put_Login("PAYPAL_REST_API_CLIENT_ID")
http.put_Password("PAYPAL_REST_API_SECRET")

#  Sends a POST request where the Content-Type is application/x-www-form-urlencoded
# resp is a CkHttpResponse
resp = http.PostUrlEncoded("https://api.sandbox.paypal.com/v1/oauth2/token",req)
if (http.get_LastMethodSuccess() != true)
    print http.lastErrorText() + "\n";
    exit
end

if (resp.get_StatusCode() != 200)
    print "Error status code: " + resp.get_StatusCode().to_s() + "\n";
    print resp.bodyStr() + "\n";

    exit
end

#  The JSON response is in the resp BodyStr property
print resp.bodyStr() + "\n";
print "-- Success." + "\n";
