class HTTParty::ConnectionAdapter
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.
@example log the uri and options
class LoggingConnectionAdapter < HTTParty::ConnectionAdapter def connection puts uri puts options Net::HTTP.new(uri) end end
@example count number of http calls
class CountingConnectionAdapter < HTTParty::ConnectionAdapter @@count = 0 self.count @@count end def connection self.count += 1 super end end
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 #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. -
:
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
Constants
- StripIpv6BracketsRegex
