Demonstrates how to get a Twitter OAuth2 token for application-only authentication.

This example is deprecated and no longer valid.

Ruby

require 'chilkat'

success = false

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

# Note: Define your Twitter apps at https://apps.twitter.com/

# We're going to send an HTTPS POST that looks like this:

# POST /oauth2/token HTTP/1.1
# Host: api.twitter.com
# User-Agent: My Twitter App v1.0.23
# Authorization: Basic eHZ6MWV2RlM0d0VFUFRHRUZQSEJvZzpMOHFxOVBaeVJn
#                      NmllS0dFS2hab2xHQzB2SldMdzhpRUo4OERSZHlPZw==
# Content-Type: application/x-www-form-urlencoded;charset=UTF-8
# Content-Length: 29
# Accept-Encoding: gzip
# 
# grant_type=client_credentials

# Update these values with your consumer key and secret (also known as API key and API secret).
consumerKey = "TWITTER_CONSUMER_KEY"
consumerSecret = "TWITTER_CONSUMER_SECRET"

http = Chilkat::CkHttp.new()

http.put_BasicAuth(true)
http.put_Login(consumerKey)
http.put_Password(consumerSecret)

req = Chilkat::CkHttpRequest.new()
req.AddParam("grant_type","client_credentials")

req.put_HttpVerb("POST")
req.put_ContentType("application/x-www-form-urlencoded")

resp = Chilkat::CkHttpResponse.new()
success = http.HttpReq("https://api.twitter.com/oauth2/token",req,resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print "Response Status Code: " + resp.get_StatusCode().to_s() + "\n";

if (resp.get_StatusCode() != 200)
    print "Expected a 200 response status code for success." + "\n";
    print resp.bodyStr() + "\n";
    exit
end

# We should get a JSON response like this:

# {
#     "token_type":"bearer",
#     "access_token":"..."
# }

json = Chilkat::CkJsonObject.new()
json.Load(resp.bodyStr())

print "Access token = " + json.stringOf("access_token") + "\n";
