copied!<p>Open-URI is convenient, but that ease of use means they're removing the access to a lot of the configuration details the other HTTP clients like Net::HTTP allow.</p> <p>It depends on what version of Ruby you're using. For 1.8.7 you can use the <a href="http://rubydoc.info/stdlib/timeout/1.9.2/frames" rel="nofollow noreferrer">Timeout</a> module. From the docs:</p> <pre><code>require 'timeout' begin status = Timeout::timeout(5) { getresult = open(cstr, "UserAgent" => "Ruby-OpenURI").read } rescue Timeout::Error => e puts e.to_s end </code></pre> <p>Then check the length of getresult to see if you got any content: </p> <pre><code>if (getresult.empty?) puts "got nothing from url" end </code></pre> <p>If you are using Ruby 1.9.2 you can add a <a href="http://rubydoc.info/stdlib/open-uri/1.9.2/frames" rel="nofollow noreferrer"><code>:read_timeout => 10</code></a> option to the <code>open()</code> method.</p> <hr> <p>Also, your code could be tightened up and made a bit more flexible. This will let you pass in a URL or default to the currently used URL. Also read Nokogiri's <a href="http://rubydoc.info/gems/nokogiri/1.4.4.2/frames" rel="nofollow noreferrer">NodeSet</a> docs to understand the difference between <code>xpath</code>, <code>/</code>, <code>css</code> and <code>at</code>, <code>%</code>, <code>at_css</code>, <code>at_xpath</code>:</p> <pre><code>def get_name_from_remote_url(cstr = 'http://someurl.com') doc = Nokogiri::XML(open(cstr, 'UserAgent' => 'Ruby-OpenURI')) # xpath returns a nodeset which has to be iterated over # my_data = doc.xpath('/session/name').text # => 'Fred' or 'Sam' etc # at returns a single node doc.at('/session/name').text end </code></pre>
