HTTPS request error: undefined method `set_body_internal' - ruby

Question

The following code fails to execute:
require 'net/http'
uri = URI('https://example.com:8443')
http = Net::HTTP.new(uri.host, uri.port)
# Enable SSL/TLS ?
if uri.scheme == "https"
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
http.ca_file = File.join(File.dirname(__FILE__), "ca-rsa-cert.pem")
end
http.start {
http.request(uri)
}
The error is:
$ ./TestCert.rb
/usr/lib/ruby/1.9.1/net/http.rb:1292:in `request': undefined method `set_body_internal'
for #<URI::HTTPS:0x00000001a47fd0 URL:https://example.com:8443> (NoMethodError)
from ./TestCert.rb:16:in `block in <main>'
from /usr/lib/ruby/1.9.1/net/http.rb:745:in `start'
from ./TestCert.rb:15:in `<main>'
Unlike Ruby NoMethodError (undefined method `set_body_internal') with HTTP get, I'm using HTTPS and I don't care about a response. I simply need Ruby to make the connection to test the SSL/TLS server.
I did try to capture a response per the related question, but that had the same error:
http.start {
response = http.request uri
}
And this had the same error:
response = http.start {
http.request uri
}
And http.get failed too (but with a different error - undefined method 'empty?'):
response = http.start {
http.get uri
}
And another failure (but with a different error - undefined method 'empty?'):
http.start {
response = http.get uri
}
If it matters, this is a Debian 7.3 (x64) system running Ruby 1.9.3p194.
How do I make a HTTP request over SSL/TLS using Ruby?

I think your call http.request(uri) is wrong, you should pass a kind of request object like Net::HTTP::Get instead of the uri. Try with the following code:
require 'net/http'
uri = URI('https://example.com:8443')
http = Net::HTTP.new(uri.host, uri.port)
# Enable SSL/TLS ?
if uri.scheme == "https"
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
http.ca_file = File.join(File.dirname(__FILE__), "ca-rsa-cert.pem")
end
req = Net::HTTP::Get.new('/')
http.request(req)
Or call directly request_get('/'). That method will create the Get object for you, like the documentation explain:
def request_get(path, initheader = nil, &block) # :yield: +response+
request(Get.new(path, initheader), &block)
end
