Adding a header into a HTTP post request

Giacecco

4/11/2006 4:32:00 PM

Dear all,
I am trying to manually build a soap envelope to call a web service,
because I cannot use soap4r: it has some strange compatibility problems
when interfacing my Oracle BPEL Process Manager.

My code is the following, and I think it is quite ok. I am only missing
how to set custom http headers in the request. I believe I need to set
"Content-Type" to "text/xml" and "SOAPAction" to "initiate. Please
help!

Gianfranco



require 'net/http'

Net::HTTP.start('whatever', 7777) do |http|
postString = '<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envel...
xmlns:xsd="http://www.w3.org/2001/XMLSc...
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance...
<soapenv:Body>
(...)
</soapenv:Body>
</soapenv:Envelope>'
response = http.post2('/whatever', postString)
case response
when Net::HTTPSuccess
puts 'Ok!'
else
response.error!
end
end

I'd check out http.rb. The method binding for post2 includes an
optional initheader argument. Not sure it this is what you need but it
sounds like it.

The documentation doesn't explain parameter "initheader" but it sounds
as if that could be what you need:

It was very easy in the end: you can add whatever http header you want
as the third parameter in post2 as in the following...

response = http.post2('/whatever', postString, {'Content-Type' =>
'text/xml', 'SOAPAction' => 'initiate'})

Thank you all for your help. Is it just me, or the Ruby documentation
is a bit weak?
