问题 How do I encode or 'escape' the URL before I use OpenURI to open(url) ? We're using OpenURI to open a remote url and return the xml: getresult = open(url).read The problem is the URL contains some user-input text that contains spaces and other characters, including "+", "&", "?", etc. potentially, so we need to safely escape the URL. I saw lots of examples when using Net::HTTP, but have not found any for OpenURI. We also need to be able to un-escape a similar string we receive in a session

问题 I am writing a Ruby 1.8.7 script which has to request really large XML files(1 - 5MB) from server which is quite slow(1min30sec for 1MB). The requested file is written to disk. I set the timeout in my script to some ridiculous amount of seconds, since I really want to get the file, not just move on if it takes too long. Still with the high amount of seconds I keep getting timeouts. Is there a best practice for this? right now I use open(DIR + "" + number + "" + ".xml", 'wb') do |file| begin

问题 I'm trying to get a url using open-uri. my code is outrageously simple url = open("http://localhost:3000/descriptions") return render :text => url.to_json When I run this code, I get a timeout error. When I request just "http://localhost:3000", I get my home page (which is correct). So it seems this is breaking on the path somewhere. I've tried using net-http with uri (not sure if that would make a difference) and I still have the same issue. I want to get a path and a query, but I can't seem
