Overview

Default connection adapter that returns a new Net::HTTP each time

Custom Connection Factories

If you like to implement your own connection adapter, subclassing HTTPParty::ConnectionAdapter will make it easier. Just override the #connection method. The uri and options attributes will have all the info you need to construct your http connection. Whatever you return from your connection method needs to adhere to the Net::HTTP interface as this is what HTTParty expects.

Configuration

There is lots of configuration data available for your connection adapter in the #options attribute. It is up to you to interpret them within your connection adapter. Take a look at the implementation of HTTParty::ConnectionAdapter#connection for examples of how they are used. Some things that are probably interesting are as follows:

  • :timeout: timeout in seconds

  • :open_timeout: http connection open_timeout in seconds, overrides timeout if set

  • :read_timeout: http connection read_timeout in seconds, overrides timeout if set

  • :debug_output: see HTTParty::ClassMethods.debug_output.

  • :pem: contains pem data. see HTTParty::ClassMethods.pem.

  • :verify: verify the server’s certificate against the ca certificate.

  • :verify_peer: set to false to turn off server verification but still send client certificate

  • :ssl_ca_file: see HTTParty::ClassMethods.ssl_ca_file.

  • :ssl_ca_path: see HTTParty::ClassMethods.ssl_ca_path.

  • :connection_adapter_options: contains the hash you passed to HTTParty.connection_adapter when you configured your connection adapter

Examples:

log the uri and options

class LoggingConnectionAdapter < HTTParty::ConnectionAdapter
  def connection
    puts uri
    puts options
    Net::HTTP.new(uri)
  end
end

count number of http calls

class CountingConnectionAdapter < HTTParty::ConnectionAdapter
  @@count = 0

  self.count
    @@count
  end

  def connection
    self.count += 1
    super
  end
end
