I''m trying to connect to a remote server in order to post an XML
request with
payment details. Can connect OK, but can''t seem to get it to log in.
I definitely have the correct username and password, since I can log in
manually at the URL through my web browser. At the moment, I do get a
response back, but it''s a "401 Authorization Required".
Have tried lots of other things like using Net::HTTP.Post.new instead, but
couldn''t ever seem to get it to work (couldn''t use SSL etc.) -
are there any
really good examples around of how to do this?
Wondered if someone could point out the mistakes in the following code, which
is where I''ve arrived at due to NoMethod errors and other problems with
the
alternative versions I tried:
require ''net/https''
def payment
limit = 5
@output_text = ""
query = render_to_string :action => ''payment'' # Generates
the XML to send
begin
response = ''''
site = Net::HTTP.new("secure-test.example.com", 443)
site.use_ssl = true
headers = {''Content-Type'' =>
''text/xml''}
response = site.post("/the/url/of/payment/system", query, headers)
response.basic_auth "username", "password" #### THE
PROBLEM LINE?
rescue
limit -= 1
if limit > 0
retry
else
raise "Could not connect to payment server"
end
end
@output_text = response.body
rescue RuntimeError => detail
flash[:error] = detail
end
Any help would be greatly appreciated!!
Thanks,
~Dave

Check out the example from here:
http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html
Here''s the relevant piece:
#3: Detailed control
url = URI.parse(''http://www.example.com/todo.cgi'')
req = Net::HTTP::Post.new(url.path)
req.basic_auth ''jack'', ''pass''
req.set_form_data({''from''=>''2005-01-01'',
''to''=>''2005-03-31''},
'';'')
res = Net::HTTP.new(url.host, url.port).start { http.request(req) }
case res
when Net::HTTPSuccess, Net::HTTPRedirection
# OK
else
res.error!
end
The important steps, it seems to me, in order (Note: I''ve never used
this
code, but I''ve done stuff in Java that has a similar flow):
1. Create a new Post object
2. Add the basic auth info
3. Set the form data
4. Send the request
The code below has some issues:
1. Its setting the headers on no object, so this line is useless
2. Its setting the basic auth information after the request has been sent

Try putting the response.basic_auth line above the post. Basic authentication parameters are sent as part of the request, so maybe try that?

Hi All,
After I run generate scaffold ActiveAlert active_alert_admin , the
resulting list.rhtml page has this code snippet at its heart:
(The database table was named active_alerts.) --
<% for column in ActiveAlert.content_columns %>
<td><%=h active_alert.send(column.name) %></td>
Can anyone explain the second line above?
OK. This seems somewhat opaque to me...I understand ActiveAlert is the ORM
object for the db table. But what is active_alert ?
Also, I have put a timestamp in one of the table columns, but its output
default is uselessly verbose. How would I capture that column''s
output and format it in a more parsimonius way?
One way I can think of is to write my own format helper and go:
myDateFormat(active_alert.send(column.name)) - The helper would regexp test
for a DateTime and reformat a DateTime using strformat()...
Any help appreciated

From what I remember, it''s because there is no "http" object ever created - who knows where it''s supposed to come from!? The problems with the other examples seemed to come from inability to log in, and overall I found available documentation to be rather thin on the ground. So, after a fair bit of searching around, I finally found this example, which logs in by creating a header rather than using basic_auth... http://www.con-way.com/XML/samplecode/Ruby/xTrackRubyCode.htm ... and modified it to end up with the following working code: require "net/https" def payment username = ''user'' password = ''pass'' paymentXmlHost = ''secure-test.example.com'' paymentXmlUri = ''/url/to/payment/script'' xmlRequest = render_to_string :action => ''payment'' # Prepare the XML view myConnection = Net::HTTP.new(paymentXmlHost,443) myConnection.use_ssl = true limit = 5 @response = "" begin mySession = myConnection.start headers = {} headers[''Content-Type''] = ''text/xml'' headers[''authorization'']=''Basic ''+Base64.b64encode(username+'':''+password) xmlResponse = mySession.request_post(paymentXmlUri, xmlRequest, headers) rescue limit -= 1 if limit > 0 retry else raise "Could not connect to payment server" end end @response = xmlResponse.body rescue RuntimeError => detail flash[:error] = detail end Still tweaking it and tidying it to do what I want it to do, but the above actually works, so hopefully will save someone else wasting time in future! Thanks everyone for the attempts at help though - I have no idea why this was so tricky to do, or why there are apparently so few detailed working examples or docs around! :-S ~Dave -- Dave Silvester Rent-A-Monkey Website Development Web: http://www.rentamonkey.com/
