The following curl command works as expected:
curl 'https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=myappid&client_secret=myclientsecret'

I want to do the same thing in my Ruby program. The following code gives me an error:

fb_access_token_url = URI.parse(                                             
    'https://graph.facebook.com/oauth/access_token' +                        
    '?grant_type=client_credentials' +                                       
    '&client_id=' + FACEBOOK_APP_ID +                                        
    '&client_secret=' + FACEBOOK_APP_SECRET)                                 
fb_access_token = Net::HTTP.get(fb_access_token_url)

So does this code:

fb_access_token_host = 'graph.facebook.com'                                  
fb_access_token_path_and_params = (                                          
    '/oauth/access_token' +                                                  
    '?grant_type=client_credentials' +                                       
    '&client_id=' + FACEBOOK_APP_ID +                                        
    '&client_secret=' + FACEBOOK_APP_SECRET)                                 
https_port = Net::HTTP.https_default_port()                                  

fb_access_token = Net::HTTP.get_response(fb_access_token_host,               
                                         fb_access_token_path_and_params,       
                                         https_port)

The error is as follows:

Errno::ECONNRESET: Connection reset by peer

    Thanks to Manoj Awasthi for making me realize that there were ssl methods that I couldn’t use.

    The problem was that I was requiring net/http rather than net/https.

    Working snippet:

    fb_access_token_url = URI.parse(                                             
    'https://graph.facebook.com/oauth/access_token' +                        
    '?grant_type=client_credentials' +                                       
    '&client_id=' + FACEBOOK_APP_ID +                                        
    '&client_secret=' + FACEBOOK_APP_SECRET)                                 
https = Net::HTTP.new(fb_access_token_url.host, fb_access_token_url.port)    
https.use_ssl = true                                                         
https.verify_mode = OpenSSL::SSL::VERIFY_NONE                                
fb_access_token = https.request_get(fb_access_token_url.path + '?' +         
                                    fb_access_token_url.query)
