Upgrading from v2.x to v3.x

Savon 3 replaces its HTTP transport client, HTTPI with Faraday, introducing major breaking changes.

While this brings significant new features and improvements, it also removes or changes some existing features and options.

Removed Options

ssl_cert_key_file, ssl_cert_key_password, ssl_cert_file, ssl_ca_cert

These options are no longer supported, as Faraday does not directly support them, and attempting to use them will raise an error.

Resolution:

For ssl_cert_key_file and ssl_cert_key_password open and decrypt the client key using OpenSSL, and provide the OpenSSL::PKey::RSA, OpenSSL::PKey::DSA as the ssl_cert_key option instead.

For ssl_cert_file pass the OpenSSL::X509::Certificate as the ssl_cert option instead.

For ssl_ca_cert pass the file as the ssl_ca_cert_file option instead.

For more information please see https://lostisland.github.io/faraday/#/customization/ssl-options

ssl_ciphers

Specifying SSL ciphers is no longer supported, as Faraday does not support this, and attempting to use this option will raise an error.

Resolution: remove code that attempts to set ssl_ciphers.

digest_auth

Digest authentication is no longer natively supported. If you need to use it, consider Faraday::DigestAuth

Changed options

cookies

The cookies option now distinguishes between empty and nil string values. If you want to send an empty cookie, you must now set it to an empty string, rather than nil. Nil is reserved for cookie flags like HttpOnly or Secure. For example:

cookies({accept: 'application/json', 'some-cookie': 'foo', "empty-cookie": "", HttpOnly: nil})

will send the following cookies:

"accept=application/json; some-cookie=foo; empty-cookie=; HttpOnly"

ssl_verify_mode

The ssl_verify_mode option now expects an OpenSSL::SSL:: constant. Previously, HTTPI would allow the passing of a symbol like :none or :peer.

ssl_verify_mode: :none

should now be written as:

ssl_verify_mode: OpenSSL::SSL::VERIFY_NONE

adapters

Savon's adapters option now forwards adapter names and options to faraday.
While not fully supported or tested, it can be used to specify a custom adapter to use. Must be compliant with faraday's adapter api.

https://lostisland.github.io/faraday/#/adapters/index

For example

client = Savon.client(
  wsdl: "http://example.com?wsdl",
  adapter: [:typhoeus, {connect_timeout: 10}]
)

Would create a savon client using the typhoeus adapter with a connect_timeout of 10 seconds.
