Hi,

I am playing arround with Net::HTTP and have this little script to  
grap a websites HTML:

require “net/http”  
page = “[http://www.google.co.uk](http://www.google.co.uk)”  
response = Net::HTTP.get\_response(URI.parse(page))  
puts response.body if response.body\_permitted?

I aim to print out the body of the response object only if it is  
permitted but I get this:

NoMethodError: undefined method `body\_permitted?’ for #\<Net::HTTPOK  
200 OK readbody=true\>

So I am not sure what is going on as get\_response returns an  
HTTPResponce object so calling body\_permitted?’ on it should work.

Any ideas?

David.

If you mean you want to print the body only for a 200 (OK) response,  
then  
one way is

require “net/http”  
page = “[http://www.google.co.uk](http://www.google.co.uk)”  
response = Net::HTTP.get\_response(URI.parse(page))  
puts response.body if Net::HTTPSuccess === response

(“ri Net::HTTP” gives a bunch of examples; if you search for  
get\_response  
you find this one, except written as a case statement)

I did a search for body\_permitted? in /usr/lib/ruby/1.8/net/http.rb, and  
I  
see it’s defined as a class method, not an instance method. So the  
following  
also works:

require “net/http”  
page = “[http://www.google.co.uk](http://www.google.co.uk)”  
response = Net::HTTP.get\_response(URI.parse(page))  
puts response.body if response.class.body\_permitted?
