Accessing Kernel namespace from within classes

Ruby
1

Hi all

Hoping someone could tell me the answer to the following.

I have a class defined in a file: TestWebsite. The main program
requires the ‘net/http’ library and also the TestWebsite file. The
class “TestWebsite” contains several class methods that use things
such as “Net::HTTP.get_response()” however I get the following errors:

/net/http.rb:380:in get_response': undefined methodrequest_uri’
for #<URI::Generic:0x2d3b9c URL:example.com> (NoMethodError)
from /opt/local/lib/ruby/1.8/net/http.rb:543:in start' from /opt/local/lib/ruby/1.8/net/http.rb:379:inget_response’
from ./test_website.rb:10:in `test’

It’s my guess the the class methods aren’t able to access the net/
http library which is in the kernel namespace, if this is true then
what must I do to allow them access?

Many thanks,

Gabriel

Are you using a complete URI or just part of one? For example,
‘domain.com’ is not a URI. Further:

[root@server15 mwhite]# ruby -r uri -e ‘p
URI.parse(“google.com”).host’
nil
[root@server15 mwhite]# ruby -r uri -e ‘p URI.parse(“http://
google.com”).host’
“google.com”

If that’s not the problem, maybe you could give us some code? Good
luck!

Oh thank you so much, you spotted that one a million miles off, I
missed out the http://. Have corrected this but now getting errors like:
./test_website.rb:13:in `test’: uninitialized constant
TestWebsite::NET (NameError)
MMM something to keep my mind ticking over.

Many thanks

No problem. If you need more help, be sure to give us the code that is
causing the error and not just the error.

You can force constants to be evaluated from the
top-level rather than from the current lexical scope by
prefixing the constant with ‘::’

class TestSuite
ok = ::Net::HTTPOK
end
