Module: HTTParty::ClassMethods

Defined in:
lib/httparty.rb

Overview

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 a 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 a Hash representing it. Normalized according to the same rules as :body. If you specify this on a POST, you must use a Hash. See also HTTParty::ClassMethods.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.

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:

  • :base_uri: see HTTParty::ClassMethods.base_uri.

  • :basic_auth: see HTTParty::ClassMethods.basic_auth. Only one of :basic_auth and :digest_auth can be used at a time; if you try using both, you’ll get an ArgumentError.

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

  • :digest_auth: see HTTParty::ClassMethods.digest_auth. Only one of :basic_auth and :digest_auth can be used at a time; if you try using both, you’ll get an ArgumentError.

  • :format: see HTTParty::ClassMethods.format.

  • :headers: see HTTParty::ClassMethods.headers. Must be a Hash.

  • :maintain_method_across_redirects: see HTTParty::ClassMethods.maintain_method_across_redirects.

  • :no_follow: see HTTParty::ClassMethods.no_follow.

  • :parser: see HTTParty::ClassMethods.parser.

  • :connection_adapter: see HTTParty::ClassMethods.connection_adapter.

  • :pem: see HTTParty::ClassMethods.pem.

  • :query_string_normalizer: see HTTParty::ClassMethods.query_string_normalizer

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

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

#ciphers(cipher_names) ⇒ Object

#query_string_normalizer(normalizer) {|Hash, String| ... } ⇒ Object

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.

Examples:

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

Parameters:

  • normalizer (Proc) —

    custom query string normalizer.

Yields:

  • (Hash, String) —

    query string

Yield Returns:

  • (Array) —

    an array that will later be joined with ‘&’
