Configuration

Savon provides a couple of basic configuration options:

Savon.configure do |config|

  # By default, Savon logs each SOAP request and response to $stdout.
  # Here's how you can disable logging:
  config.log = false

  # The default log level used by Savon is :debug.
  config.log_level = :info

  # In a Rails application you might want Savon to use the Rails logger.
  config.logger = Rails.logger

  # The XML logged by Savon can be formatted for debugging purposes.
  # Unfortunately, this feature comes with a performance and is not
  # recommended for production environments.
  config.pretty_print_xml = true

  # Savon raises SOAP and HTTP errors, but you can disabling this behavior.
  config.raise_errors = false

  # Savon expects your service to use SOAP 1.1. You can change that to 1.2
  # which affects error handling and smaller differences. If you have to
  # set this, it's probably a bug. Please open a ticket.
  config.soap_version = 2

  # The XML namespace identifier used for the SOAP envelope defaults to :env
  # but can be configured to use a different identifier. If you need this
  # feature, please open a ticket because Savon should figure out the
  # namespace and identifier itself.
  config.env_namespace = :soapenv

  # The SOAP header can be configured to default to a Hash that gets
  # translated to XML by Gyoku. I would love to remove this feature,
  # so if you rely on it, open a ticket and let me know why you need it.
  config.soap_header = { auth: { username: "admin", password: "secret" } }

end

The example above used the global config. Each Savon::Client clones the global config on instantiation to allow different client objects to use a different logger, custom error handling or any other setting.

Here's an example of how to access the per-client config and change the error handling:

client = Savon.client("http://service.example.com?wsdl")
client.config.raise_errors = false

Please note that disabling Savon's logger does not disable logging of any dependant libraries.
HTTPI for example will continue to log HTTP requests and has to be configured separately. Here's how you can disable logging for HTTPI:

HTTPI.log = false
