# Public: Parse response bodies as YAML.
#
# Warning: This is not backwards compatible with versions of this middleware prior to
# faraday_middleware v0.12 - prior to this version, we used YAML.load rather than
# YAMl.safe_load, which exposes serious remote code execution risks - see
# https://github.com/ruby/psych/issues/119 for details. If you're sure you can trust
# YAML you're passing, you can set up an unsafe version of this middleware as follows:
#
# class UnsafelyParseYaml < FaradayMiddleware::ResponseMiddleware
# dependency do
# require 'yaml'
# end
#
# define_parser do |body|
# YAML.load body
# end
# end
#
# Faraday.new(..) do |config|
# config.use UnsafelyParseYaml
# ...
# end
class ParseYaml < ResponseMiddleware
dependency 'safe_yaml/load'
define_parser do |body, parser_options|
if SafeYAML::YAML_ENGINE == 'psych'
SafeYAML.load(body, nil, parser_options || {})
else
SafeYAML.load(body, parser_options || {})
end
end
end
end
# deprecated alias
Faraday::Response::ParseYaml = FaradayMiddleware::ParseYaml
