Hi, i have to open an uri with open-uri but URI is raising me an error that an URL is an invalid uri: > > p URI.split(“[http://xpto.com/index.asp?action=showproduct&id={D3E21D33-6DFF-4355-9324-AE1395CEB247}](http://xpto.com/index.asp?action=showproduct&id=%7BD3E21D33-6DFF-4355-9324-AE1395CEB247%7D)”) > > URI::InvalidURIError: bad URI(is not URI?): > > [http://xpto.com/index.asp?action=showproduct&id={D3E21D33-6DFF-4355-9324-AE1395CEB247}](http://xpto.com/index.asp?action=showproduct&id=%7BD3E21D33-6DFF-4355-9324-AE1395CEB247%7D) > > from > > /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/uri/common.rb:436:in > > `split’ > > from (irb):8 > > from :0 That’s a strange ID but valid. I even checked the RFC 2396 and {} is not a reserved character. Best regards, VP ---

If you also supply a patch against the uri lib, you get bonus points 🙂 ---

Rob, to be in the ‘unwise’ doesn’t mean that it not conforms to the standard for URIs. I’m escaping and it works, but in my option it could be handled by the lib.

Sorry, Victor, but yes it does. Quoting from the end of RFC 2396 section 2.4.3: > [@](#): > > Other characters are excluded because gateways and other transport > agents are known to sometimes modify such characters, or they are used > as delimiters. > unwise = “{” | “}” | “|” | "" | “^” | “[” | “]” | “`” > Data corresponding to excluded characters must be escaped in order to > be properly represented within a URI. So that last sentence pretty much nails it. Curly braces “…must be escaped in order to be properly represented within a URI.” So you’ll have to continue to escape them yourself. It wouldn’t be right for the URI class to depart from the standard here. -Rob On Aug 28, 2009, at 11:40 AM, Victor Pereira wrote: > Rob B. wrote: > > > here a description of those US-ASCII characters that have been > > irb\> u="[http://xpto.com/index.asp](http://xpto.com/index.asp)? > > > > > Michael F. > > > CTO, The Rubyists, LLC > > > 972-996-5199 > > > > Rob B.
