Defined in:

lib/github_api/response/follow_redirects.rb

Public: Follow HTTP 301, 302, 303, 307, and 308 redirects.

For HTTP 301, 302, and 303, the original GET, POST, PUT, DELETE, or PATCH request gets converted into a GET. With ‘:standards_compliant => true`, however, the HTTP method after 301/302 remains unchanged. This allows you to opt into HTTP/1.1 compliance and act unlike the major web browsers.

This middleware currently only works with synchronous requests; i.e. it doesn’t support parallelism.

If you wish to persist cookies across redirects, you could use the faraday-cookie_jar gem:

Faraday.new(:url => url) do |faraday|
  faraday.use FaradayMiddleware::FollowRedirects
  faraday.use :cookie_jar
  faraday.adapter Faraday.default_adapter
end

ALLOWED_METHODS =

HTTP methods for which 30x redirects can be followed

Set.new [:head, :options, :get, :post, :put, :patch, :delete]

REDIRECT_CODES =

HTTP redirect status codes that this middleware implements

Set.new [301, 302, 303, 307, 308]

ENV_TO_CLEAR =

Keys in env hash which will get cleared between requests

Set.new [:status, :response, :response_headers]

FOLLOW_LIMIT =

Default value for max redirects followed

3

URI_UNSAFE =

Regex that matches characters that need to be escaped in URLs, sans the “%” character which we assume already represents an escaped sequence.

/[^\-_.!~*'()a-zA-Z\d;\/?:@&=+$,\[\]%]/

• #call(env) ⇒ Object
• #initialize(app, options = {}) ⇒ FollowRedirects constructor

  Public: Initialize the middleware.

Public: Initialize the middleware.

options - An options Hash (default: {}):

:limit               - A Numeric redirect limit (default: 3)
:standards_compliant - A Boolean indicating whether to respect
                       the HTTP spec when following 301/302
                       (default: false)
:callback            - A callable that will be called on redirects
                       with the old and new envs
