Hello, I want to retrieve an image from the world wind server using the Ruby http package. But I can't get it work. In tcl/tk it works like this: package require http set url "[http://data.worldwind.arc.nasa.gov/t?T=105&L=0&X=81&Y=48](http://data.worldwind.arc.nasa.gov/t?T=105&L=0&X=81&Y=48)" set token [::http:geturl $url] upvar #0 $token state and the jpeg image is in the state(body) variable. Using Ruby I expected something like this: require 'net/http' server = '[http://data.worldwind.arc.nasa.gov](http://data.worldwind.arc.nasa.gov)' request = '/t?T=105&L=0&X=81&Y=48' http = Net::HTTP.new(server) http.start resp,data = http.get(request, nil) http.finish But http.start returns "SocketError: getaddrinfo: no address associated with hostname." always. Is there a command like geturl in the net/http package? > **···** > > -- > Rasmus ---

You behind a proxy? There is another method in http which takes proxy host / port as an argument. > **···** > > On 8/17/05, Rasmus Debitsch \ wrote: > > > Hello, > > > > I want to retrieve an image from the world wind server using the Ruby http > > package.

Now it works. Sometimes it is so easy. Thanks, Rasmus "Mohit Muthanna" \ schrieb im Newsbeitrag news:fdb3980a05081713547af1fd61@mail.gmail.com...

I'd say the server method shouldn't accept url specs ([http://servername](http://servername) is not a server name, it is a url). There could be a url or address method which accepts a url (i.e. protocol://server:port/request), but the methods server, port, and request should accept just that. > **···** > > On 8/17/05, Daniel Berger \ wrote: > > > Mohit Muthanna wrote: > > \> Remove the 'http://' from the 'server' variable. > > > > It would take a minimal amount of code to make it work with or without > > the "http://" prefix.

You should be using the URI class to parse and assemble URLs; there's no need to duplicate that functionality in net/http. URI provides address and port accessors. Also, if you want an easy wrapper around net/http and uri, there's already open-uri. (Also, I've contributed some improved documentation for net/http which will hopefully make it to ruby-doc.org soon.) mathew > **···** > > -- > \           WE HAVE TACOS
