I met a problem using open-uri.
I want to set the timeout of the open process. And i see the open method has
a option named "read_timeout".
So i just code as
open("www.abc.com", {:read_timeout => 10}).
But, i can't see the effect. What's wrong with that? Any help thanks.
You can use the timeout library.
timeout(10) do
open "www.abc.com"
end
it raises a TimeoutError if the request doesn't complete in 10 seconds.

Yes, i know that. Thanks. 
But i confused by the read_timeout option of the open method.

timeout(10) do
open "www.abc.com"
endit raises a TimeoutError if the request doesn't complete in 10 seconds.

Read here. it might help:
open(name, *rest, &block)
makes possible to open various resources including URIs. If the first
argument respond to `open’ method, the method is called with the rest
arguments.
If the first argument is a string which begins with xxx://, it is parsed
by URI.parse. If the parsed object respond to `open’ method, the method
is called with the rest arguments.
Otherwise original open is called.
Since open-uri.rb provides URI::HTTP#open, URI::HTTPS#open and
URI::FTP#open, Kernel[#.]open can accepts such URIs and strings which
begins with http://, https:// and ftp://. In these case, the opened file
object is extended by OpenURI::Meta.

Where did you see a read_timeout option? I can't find it in any
documentation, although I might be missing something.
Also you are opening "www.abc.com" which Kernel open is seeing as a
file name rather than a URI.

thanks.Where did you see a read_timeout option? I can't find it in any

Oh, sorry, it's my mistake of careless.

What's your version? No read_timeout option of the open-uri version in Ruby
1.8. But 1.9 or openuri in rubygems has.
module OpenURI
Options = {
:proxy => true,
:proxy_http_basic_authentication => true,
:progress_proc => true,
:content_length_proc => true,
:http_basic_authentication => true,

Well I must have missed where you said that you were using 1.9. <G>
The general assumption is that folks are using 1.8.x which is the
stable branch, 1.9 is experimental.
In any case, if you're trying to open "www.abc.com" instead of
"http://www.abc.com" the OpenURI code isn't going to come into play
anyway. I don't think that 1.9 changed that. In fact here's the
actual 1.9 code in lib/open-uri.rb which monkeypatches Kernel#open
def open(name, *rest, &block) # :doc:
if name.respond_to?(:open)
name.open(*rest, &block)
elsif name.respond_to?(:to_str) &&
%r{\A[A-Za-z][A-Za-z0-9+\-\.]*://} =~ name &&
(uri = URI.parse(name)).respond_to?(:open)
uri.open(*rest, &block)
else
open_uri_original_open(name, *rest, &block)
end
end
