Ruby: Checking if URI is HTTPS?
I would like to check if the URI will need SSL authentication:
url = URI.parse("http://www.google.com") # [some code] if url.instance_of? URI::HTTPS http.use_ssl=true http.verify_mode = OpenSSL::SSL::VERIFY_NONE end
However, those few lines throw the following error..
/usr/lib/ruby/1.8/uri/common.rb:436:in `split': bad URI(is not URI?): HTTPS (URI::InvalidURIError) from /usr/lib/ruby/1.8/uri/common.rb:485:in `parse' from /usr/lib/ruby/1.8/uri/common.rb:608:in `URI' from links.rb:18
Why is it happening?
>> uri = URI.parse("http://www.google.com") => #<URI::HTTP:0x1014ca458 URL:http://www.google.com> >> uri.scheme => "http" >> uri = URI.parse("https://mail.google.com") => #<URI::HTTPS:0x1014c2e60 URL:https://mail.google.com> >> uri.scheme => "https"
So you could check uri's scheme against simple "https" string.
as shown in the previous answer, HTTP and HTTPS are different classes. in particular, HTTPS is a subclass of the HTTP class. thus you could check with instance_of?.
http = URI.parse "http://example.com" https = URI.parse "https://example.com" http.instance_of? URI::HTTPS #=> false https.instance_of? URI::HTTPS #=> true
but if this hierarchy ever gets changed, then your code could break, thus the above answer might be more future-proof.
