Geturl with net/http package

[Rasmus Debitsch]

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"
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'
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?

You behind a proxy? There is another method in http which takes proxy
host / port as an argument.

Remove the 'http://' from the 'server' variable.

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. Any chance this could be patched?

I also recommend accessors for @address and @port.

I'd say the server method shouldn't accept url specs
(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://serverort/request), but the methods server, port, and
request should accept just that.

Now it works. Sometimes it is so easy.
