Hi,  
In the following test script (similar to pickaxe p. 700 ):

require ‘net/http’  
require ‘uri’

def fetch (uri\_str, limit=10)  
fail ‘http redirect limit exceeded’ if limit.zero?  
response = Net::HTTP.get\_response(URI.parse(uri\_str))  
case response  
when Net::HTTPSuccess  
response  
when Net::HTTPRedirection  
fetch(response[‘location’], limit-1)  
else  
response.error!  
end  
end

fetch(‘[heise.de](http://heise.de)’);

with  
ruby test.rb  
I get the result:

Exception `NoMethodError’ at /usr/local/lib/ruby/1.8/net/http.rb:380

- undefined method `request_uri' for #<URI::Generic:0x188f84 URL:heise.de> /usr/local/lib/ruby/1.8/net/http.rb:380:in `get\_response’: undefined  
method `request_uri' for #<URI::Generic:0x188f84 URL:heise.de> (NoMethodError) from /usr/local/lib/ruby/1.8/net/http.rb:545:in `start’  
from /usr/local/lib/ruby/1.8/net/http.rb:379:in `get_response' from test.rb:6:in `fetch’  
from test.rb:18

I had a look at /usr/local/lib/ruby/1.8/uri/http.rb  
The function was defined there:

# 

```
 # == Description
 #
 # Returns: path + '?' + query
 #
 def request_uri
   r = path_query
   if r[0] != ?/
     r = '/' + r
   end

   r
 end

```

It should be a function of the standard libray. I am quite new to  
ruby. How can I debug this problem? Or any hints what I can do?

Thanks in advance for your help,

Holger

this is not a uri.

try

harp:~ \> ruby -r uri -e’ p URI.parse(“[heise.de](http://heise.de)”).host ’  
nil

harp:~ \> ruby -r uri -e’ p URI.parse(“[http://heise.de](http://heise.de)”).host ’  
“[heise.de](http://heise.de)”

Oh my god … thank you vey much. You are right. I was a it confused  
because of the NoMethodError and I thought I had installed something  
wrongly. Thanks for your hint 🙂
