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 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 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 an object which responds to #to_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.

#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

Yields:

  • (Hash, String)

    query string

Yield Returns:

  • (Array)

    an array that will later be joined with '&'

  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) ⇒ Object

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.

Examples:

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

#ssl_ca_file(path) ⇒ Object

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.
