module HTTParty::ClassMethods

Common Request Options

Request methods (get, post, patch, put, delete, head, options) all take a common set of options. These are:

:body:

Body of the request. If passed an object that responds to to_hash, will try to normalize it first, by default passing it to ActiveSupport::to_params. Any other kind of object will get used as-is.

:http_proxyaddr:

Address of proxy server to use.

:http_proxyport:

Port of proxy server to use.

:http_proxyuser:

User for proxy server authentication.

:http_proxypass:

Password for proxy server authentication.

:limit:

Maximum number of redirects to follow. Takes precedences over :no_follow.

:query:

Query string, or an object that responds to to_hash representing it. Normalized according to the same rules as :body. If you specify this on a POST, you must use an object which responds to to_hash. See also #default_params.

:timeout:

Timeout for opening connection and reading data.

:+local_host:

Local address to bind to before connecting.

:+local_port:

Local port to bind to before connecting.

:+body_steam:

Allow streaming to a REST server to specify a body_stream.

:+stream_body:

Allow for streaming large files without loading them into memory.

There are also another set of options with names corresponding to various class methods. The methods in question are those that let you set a class-wide default, and the options override the defaults on a request-by-request basis. Those options are:

end
maintain_method_across_redirects(value = true) click to toggle source

Declare that you wish to maintain the chosen HTTP method across redirects. The default behavior is to follow redirects via the GET method, except if you are making a HEAD request, in which case the default is to follow all redirects with HEAD requests. If you wish to maintain the original method, you can set this option to true.

@example

class Foo
  include HTTParty

@see HTTParty::ResponseError#response

@example

class Foo
  include HTTParty
  base_uri 'http://google.com'
  no_follow true
end

end
# File lib/httparty.rb, line 173
def open_timeout(t)
  raise ArgumentError, 'open_timeout must be an integer or float' unless t && (t.is_a?(Integer) || t.is_a?(Float))
  default_options[:open_timeout] = t
end
options(path, options = {}, &block) click to toggle source

Perform an OPTIONS request to a path

# File lib/httparty.rb, line 527
def options(path, options = {}, &block)
  perform_request Net::HTTP::Options, path, options, &block

class Foo
  include HTTParty
  pem File.read('/home/user/my.pem'), "optional password"
end
# File lib/httparty.rb, line 311
def pem(pem_contents, password = nil)
  default_options[:pem] = pem_contents
  default_options[:pem_password] = password
end
pkcs12(p12_contents, password) click to toggle source

Allows setting a PKCS12 file to be used

class Foo
  include HTTParty
  pkcs12 File.read('/home/user/my.p12'), "password"
end
# File lib/httparty.rb, line 322
def pkcs12(p12_contents, password)
  default_options[:p12] = p12_contents
  default_options[:p12_password] = password
end
post(path, options = {}, &block) click to toggle source

Allows making a post request to a url.

class Foo
  include HTTParty
end

# Simple post with full url and setting the body
Foo.post('http://foo.com/resources', body: {bar: 'baz'})

# Simple post with full url using :query option,
# which gets set as form data on the request.
Foo.post('http://foo.com/resources', query: {bar: 'baz'})
# File lib/httparty.rb, line 491
def post(path, options = {}, &block)

def put(path, options = {}, &block)
  perform_request Net::HTTP::Put, path, options, &block
end
query_string_normalizer(normalizer) click to toggle source

Override the way query strings are normalized. Helpful for overriding the default rails normalization of Array queries.

For a query:

get '/', query: {selected_ids: [1,2,3]}

The default query string normalizer returns:

/?selected_ids[]=1&selected_ids[]=2&selected_ids[]=3

Let's change it to this:

/?selected_ids=1&selected_ids=2&selected_ids=3

Pass a Proc to the query normalizer which accepts the yielded query.

@example Modifying Array query strings

class ServiceWrapper
  include HTTParty

  query_string_normalizer proc { |query|
    query.map do |key, value|
      value.map {|v| "#{key}=#{v}"}
    end.join('&')
  }
end

@param [Proc] normalizer custom query string normalizer. @yield [Hash, String] query string @yieldreturn [Array] an array that will later be joined with '&'

# File lib/httparty.rb, line 355
def query_string_normalizer(normalizer)
  default_options[:query_string_normalizer] = normalizer
end
read_timeout(t) click to toggle source

Allows setting a default #read_timeout for all HTTP calls in seconds

class Foo
  include HTTParty
  read_timeout 10
end
# File lib/httparty.rb, line 184
def read_timeout(t)
  raise ArgumentError, 'read_timeout must be an integer or float' unless t && (t.is_a?(Integer) || t.is_a?(Float))
  default_options[:read_timeout] = t
end
resend_on_redirect(value = true) click to toggle source

Declare that you wish to resend the full HTTP request across redirects, even on redirects that should logically become GET requests. A 303 redirect in HTTP signifies that the redirected url should normally retrieved using a GET request, for instance, it is the output of a previous POST. #maintain_method_across_redirects respects this behavior, but you can force HTTParty to #resend_on_redirect even on 303 responses.

@example

class Foo
  include HTTParty
  base_uri 'http://google.com'
  resend_on_redirect
end
# File lib/httparty.rb, line 301
def resend_on_redirect(value = true)
  default_options[:resend_on_redirect] = value
end
ssl_ca_file(path) click to toggle source

Allows setting an OpenSSL certificate authority file. The file should contain one or more certificates in PEM format.

Setting this option enables certificate verification. All certificates along a chain must be available in #ssl_ca_file or #ssl_ca_path for verification to succeed.

class Foo
  include HTTParty
  ssl_ca_file '/etc/ssl/certs/ca-certificates.crt'
end
# File lib/httparty.rb, line 395
def ssl_ca_file(path)
  default_options[:ssl_ca_file] = path
end
ssl_ca_path(path) click to toggle source

Allows setting an OpenSSL certificate authority path (directory).

Setting this option enables certificate verification. All certificates along a chain must be available in #ssl_ca_file or #ssl_ca_path for verification to succeed.

class Foo
  include HTTParty
  ssl_ca_path '/etc/ssl/certs/'
end
# File lib/httparty.rb, line 409
def ssl_ca_path(path)
  default_options[:ssl_ca_path] = path
end

Allows setting of SSL version to use. This only works in Ruby 1.9+. You can get a list of valid versions from OpenSSL::SSL::SSLContext::METHODS.

class Foo
  include HTTParty
  ssl_version :SSLv3
end
# File lib/httparty.rb, line 366
def ssl_version(version)
  default_options[:ssl_version] = version
end
uri_adapter(uri_adapter) click to toggle source

Allows setting a custom URI adapter.

class Foo
  include HTTParty
  uri_adapter Addressable::URI
end
# File lib/httparty.rb, line 434
def uri_adapter(uri_adapter)
  raise ArgumentError, 'The URI adapter should respond to #parse' unless uri_adapter.respond_to?(:parse)
  default_options[:uri_adapter] = uri_adapter
end
