Savon: How to change header from being <env:Header> to <soap:Header> or something different

In Savon, is there a way开发者_StackOverflow中文版 to change

<env:Header>

to be

<soap:Header>

or anything different?

I've tried in the request block putting an additional header tag like this:

soap.header['soap:Header']

But that won't work.

I've browsed Savon Docs and haven't found anywhere to change that tag, only by manually building the XML.

EDITED for Savon 1.0.0

The value can be set in the configure block where you can also set logging and other parameters. Simply put

Savon.configure do |c|
  c.env_namespace = :soap
end

into your code.

For newer versions of Savon:

Savon.client(env_namespace: :soapenv)
