-## What
+# Ruby OAuth 2 has moved to GitLab
 
-OAuth 2.0 is the industry-standard protocol for authorization.
-OAuth 2.0 focuses on client developer simplicity while providing specific authorization flows for web applications,
-    desktop applications, mobile phones, and living room devices.
-This is a RubyGem for implementing OAuth 2.0 clients and servers in Ruby applications.
-See the sibling `oauth` gem for OAuth 1.0 implementations in Ruby.
+Please update references: https://gitlab.com/oauth-xx/oauth2/

-## What is new for v2.0?
-
-- Officially support Ruby versions >= 2.7
-- Unofficially support Ruby versions >= 2.5
-- Incidentally support Ruby versions >= 2.2
-- Drop support for the expired MAC Draft (all versions)
-- Support IETF rfc7523 JWT Bearer Tokens
-- Support IETF rfc7231 Relative Location in Redirect
-- Support IETF rfc6749 Don't set oauth params when nil
-- Support [OIDC 1.0 Private Key JWT](https://openid.net/specs/openid-connect-core-1_0.html#ClientAuthentication); based on the OAuth JWT assertion specification [(RFC 7523)](https://tools.ietf.org/html/rfc7523)
-- Support new formats, including from [jsonapi.org](http://jsonapi.org/format/): `application/vdn.api+json`, `application/vnd.collection+json`, `application/hal+json`, `application/problem+json`
-- Adds new option to `OAuth2::Client#get_token`:
-    - `:access_token_class` (`AccessToken`); user specified class to use for all calls to `get_token`
-- Adds new option to `OAuth2::AccessToken#initialize`:
-    - `:expires_latency` (`nil`); number of seconds by which AccessToken validity will be reduced to offset latency
-- By default, keys are transformed to camel case.
-  - Original keys will still work as previously, in most scenarios, thanks to `rash_alt` gem.
-  - However, this is a _breaking_ change if you rely on `response.parsed.to_h`, as the keys in the result will be camel case.
-  - As of version 2.0.4 you can turn key transformation off with the `snaky: false` option.
-- By default, the `:auth_scheme` is now `:basic_auth` (instead of `:request_body`)
-  - Third-party strategies and gems may need to be updated if a provider was requiring client id/secret in the request body
-- [... A lot more](https://github.com/oauth-xx/oauth2/blob/master/CHANGELOG.md#2.0.0)

-## Compatibility
-
-Targeted ruby compatibility is non-EOL versions of Ruby, currently 2.7, 3.0 and
-3.1. Compatibility is further distinguished by supported and unsupported versions of Ruby.
-Ruby is limited to 2.2+ for 2.x releases. See `1-4-stable` branch for older rubies.
-
-<details>
-  <summary>Ruby Engine Compatibility Policy</summary>
-
-This gem is tested against MRI, JRuby, and Truffleruby.
-Each of those has varying versions that target a specific version of MRI Ruby.
-This gem should work in the just-listed Ruby engines according to the targeted MRI compatibility in the table below.
-If you would like to add support for additional engines,
-  first make sure Github Actions supports the engine,
-  then submit a PR to the correct maintenance branch as according to the table below.
-</details>
-
-<details>
-  <summary>Ruby Version Compatibility Policy</summary>
-
-If something doesn't work on one of these interpreters, it's a bug.
-
-This library may inadvertently work (or seem to work) on other Ruby
-implementations, however support will only be provided for the versions listed
-above.
-
-If you would like this library to support another Ruby version, you may
-volunteer to be a maintainer. Being a maintainer entails making sure all tests
-run and pass on that implementation. When something breaks on your
-implementation, you will be responsible for providing patches in a timely
-fashion. If critical issues for a particular implementation exist at the time
-of a major release, support for that Ruby version may be dropped.

-## Usage Examples
-
-### `authorize_url` and `token_url` are on site root (Just Works!)
-
-```ruby
-require 'oauth2'
-client = OAuth2::Client.new('client_id', 'client_secret', site: 'https://example.org')
-# => #<OAuth2::Client:0x00000001204c8288 @id="client_id", @secret="client_sec...
-client.auth_code.authorize_url(redirect_uri: 'http://localhost:8080/oauth2/callback')
-# => "https://example.org/oauth/authorize?client_id=client_id&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Foauth2%2Fcallback&response_type=code"
-
-access = client.auth_code.get_token('authorization_code_value', redirect_uri: 'http://localhost:8080/oauth2/callback', headers: {'Authorization' => 'Basic some_password'})
-response = access.get('/api/resource', params: {'query_foo' => 'bar'})
-response.class.name
-# => OAuth2::Response
-```
-
-### Relative `authorize_url` and `token_url` (Not on site root, Just Works!)
-
-In above example, the default Authorization URL is `oauth/authorize` and default Access Token URL is `oauth/token`, and, as they are missing a leading `/`, both are relative.
-
-```ruby
-client = OAuth2::Client.new('client_id', 'client_secret', site: 'https://example.org/nested/directory/on/your/server')
-# => #<OAuth2::Client:0x00000001204c8288 @id="client_id", @secret="client_sec...
-client.auth_code.authorize_url(redirect_uri: 'http://localhost:8080/oauth2/callback')
-# => "https://example.org/nested/directory/on/your/server/oauth/authorize?client_id=client_id&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Foauth2%2Fcallback&response_type=code"
-```
-
-### Customize `authorize_url` and `token_url`
-
-You can specify custom URLs for authorization and access token, and when using a leading `/` they will _not be relative_, as shown below:
-
-```ruby
-client = OAuth2::Client.new('client_id', 'client_secret',
-                            site: 'https://example.org/nested/directory/on/your/server',
-                            authorize_url: '/jaunty/authorize/',
-                            token_url: '/stirrups/access_token')
-# => #<OAuth2::Client:0x00000001204c8288 @id="client_id", @secret="client_sec...
-client.auth_code.authorize_url(redirect_uri: 'http://localhost:8080/oauth2/callback')
-# => "https://example.org/jaunty/authorize/?client_id=client_id&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Foauth2%2Fcallback&response_type=code"
-client.class.name
-# => OAuth2::Client
-```
-
-### snake_case and indifferent access in Response#parsed
-
-```ruby
-response = access.get('/api/resource', params: {'query_foo' => 'bar'})
-# Even if the actual response is CamelCase. it will be made available as snaky:
-JSON.parse(response.body)         # => {"accessToken"=>"aaaaaaaa", "additionalData"=>"additional"}
-response.parsed                   # => {"access_token"=>"aaaaaaaa", "additional_data"=>"additional"}
-response.parsed.access_token      # => "aaaaaaaa"
-response.parsed[:access_token]    # => "aaaaaaaa"
-response.parsed.additional_data   # => "additional"
-response.parsed[:additional_data] # => "additional"
-response.parsed.class.name        # => OAuth2::SnakyHash (subclass of Hashie::Mash::Rash, from `rash_alt` gem)
-```
-
-#### What if I hate snakes and/or indifference?
-
-```ruby
-response = access.get('/api/resource', params: {'query_foo' => 'bar'}, snaky: false)
-JSON.parse(response.body)         # => {"accessToken"=>"aaaaaaaa", "additionalData"=>"additional"}
-response.parsed                   # => {"accessToken"=>"aaaaaaaa", "additionalData"=>"additional"}
-response.parsed['accessToken']    # => "aaaaaaaa"
-response.parsed['additionalData'] # => "additional"
-response.parsed.class.name        # => Hash (just, regular old Hash)
-```
-
-<details>
-  <summary>Debugging</summary>
-
-Set an environment variable, however you would [normally do that](https://github.com/bkeepers/dotenv).
-
-```ruby
-# will log both request and response, including bodies
-ENV['OAUTH_DEBUG'] = 'true'
-```
-
-By default, debug output will go to `$stdout`. This can be overridden when
-initializing your OAuth2::Client.
-
-```ruby
-require 'oauth2'
-client = OAuth2::Client.new(
-  'client_id',
-  'client_secret',
-  site: 'https://example.org',
-  logger: Logger.new('example.log', 'weekly')
-)
-```
-</details>
-
-## OAuth2::Response
-
-The `AccessToken` methods `#get`, `#post`, `#put` and `#delete` and the generic `#request`
-will return an instance of the #OAuth2::Response class.
-
-This instance contains a `#parsed` method that will parse the response body and
-return a Hash-like [`OAuth2::SnakyHash`](https://github.com/oauth-xx/oauth2/blob/master/lib/oauth2/snaky_hash.rb) if the `Content-Type` is `application/x-www-form-urlencoded` or if
-the body is a JSON object.  It will return an Array if the body is a JSON
-array.  Otherwise, it will return the original body string.
-
-The original response body, headers, and status can be accessed via their
-respective methods.
-
-## OAuth2::AccessToken
-
-If you have an existing Access Token for a user, you can initialize an instance
-using various class methods including the standard new, `from_hash` (if you have
-a hash of the values), or `from_kvform` (if you have an
-`application/x-www-form-urlencoded` encoded string of the values).
-
-## OAuth2::Error
-
-On 400+ status code responses, an `OAuth2::Error` will be raised.  If it is a
-standard OAuth2 error response, the body will be parsed and `#code` and `#description` will contain the values provided from the error and
-`error_description` parameters.  The `#response` property of `OAuth2::Error` will
-always contain the `OAuth2::Response` instance.
-
-If you do not want an error to be raised, you may use `:raise_errors => false`
-option on initialization of the client.  In this case the `OAuth2::Response`
-instance will be returned as usual and on 400+ status code responses, the
-Response instance will contain the `OAuth2::Error` instance.
-
-## Authorization Grants
-
-Currently the Authorization Code, Implicit, Resource Owner Password Credentials, Client Credentials, and Assertion
-authentication grant types have helper strategy classes that simplify client
-use. They are available via the [`#auth_code`](https://github.com/oauth-xx/oauth2/blob/master/lib/oauth2/strategy/auth_code.rb), [`#implicit`](https://github.com/oauth-xx/oauth2/blob/master/lib/oauth2/strategy/implicit.rb), [`#password`](https://github.com/oauth-xx/oauth2/blob/master/lib/oauth2/strategy/password.rb), [`#client_credentials`](https://github.com/oauth-xx/oauth2/blob/master/lib/oauth2/strategy/client_credentials.rb), and [`#assertion`](https://github.com/oauth-xx/oauth2/blob/master/lib/oauth2/strategy/assertion.rb) methods respectively.
-
-These aren't full examples, but demonstrative of the differences between usage for each strategy.
-```ruby
-auth_url = client.auth_code.authorize_url(redirect_uri: 'http://localhost:8080/oauth/callback')
-access = client.auth_code.get_token('code_value', redirect_uri: 'http://localhost:8080/oauth/callback')
-
-auth_url = client.implicit.authorize_url(redirect_uri: 'http://localhost:8080/oauth/callback')
-# get the token params in the callback and
-access = OAuth2::AccessToken.from_kvform(client, query_string)
-
-access = client.password.get_token('username', 'password')
-
-access = client.client_credentials.get_token
-
-# Client Assertion Strategy
-# see: https://tools.ietf.org/html/rfc7523
-claimset = {
-  iss: 'http://localhost:3001',
-  aud: 'http://localhost:8080/oauth2/token',
-  sub: 'me@example.com',
-  exp: Time.now.utc.to_i + 3600,
-}
-assertion_params = [claimset, 'HS256', 'secret_key']
-access = client.assertion.get_token(assertion_params)
-
-# The `access` (i.e. access token) is then used like so:
-access.token # actual access_token string, if you need it somewhere
-access.get('/api/stuff') # making api calls with access token
-```
-
-If you want to specify additional headers to be sent out with the
-request, add a 'headers' hash under 'params':
-
-```ruby
-access = client.auth_code.get_token('code_value', redirect_uri: 'http://localhost:8080/oauth/callback', headers: {'Some' => 'Header'})
-```
-
-You can always use the `#request` method on the `OAuth2::Client` instance to make
-requests for tokens for any Authentication grant type.
-
-## Versioning
-
-This library aims to adhere to [Semantic Versioning 2.0.0][semver].
-Violations of this scheme should be reported as bugs. Specifically,
-if a minor or patch version is released that breaks backward
-compatibility, a new version should be immediately released that
-restores compatibility. Breaking changes to the public API will
-only be introduced with new major versions.
-
-As a result of this policy, you can (and should) specify a
-dependency on this gem using the [Pessimistic Version Constraint][pvc] with two digits of precision.
-
-For example:
-
-```ruby
-spec.add_dependency 'oauth2', '~> 2.0'
-```

-# History
-
-`faraday` v0.17.3 is the first version that stops using `&Proc.new` for block forwarding,
-   and thus is the oldest version oauth2 is compatible with.
-
-```ruby
-gem 'faraday', ['>= 0.17.3', '< 3.0']
-```
-
-# Ruby
-
-We use the Github Action `ruby/setup-ruby@master` to install Ruby, and it has a matrix of
-[supported versions](https://github.com/ruby/setup-ruby/blob/master/README.md#supported-versions) (copied below).
-
-| Interpreter           | Versions                                                                                 |
-|-----------------------|------------------------------------------------------------------------------------------|
-| `ruby`                | 1.9.3, 2.0.0, 2.1.9, 2.2, all versions from 2.3.0 until 3.1.1, head, debug, mingw, mswin |
-| `jruby`               | 9.1.17.0 - 9.3.3.0, head                                                                 |
-| `truffleruby`         | 19.3.0 - 22.0.0, head                                                                    |
-| `truffleruby+graalvm` | 21.2.0 - 22.0.0, head                                                                    |
-
-In the naming of gemfiles, we will use the below shorthand for interpreter,
-and version. Platforms will be represented without modification.
-
-| Interpreter           | Shorthand |
-|-----------------------|-----------|
-| `ruby`                | r         |
-| `jruby`               | jr        |
-| `truffleruby`         | tr        |
-| `truffleruby+graalvm` | trg       |
-
-Building onto that, we can add the MRI target spec,
-since that's what all Rubygems use for minimum version compatibility.
-
-| Interpreter + Version      | MRI spec | Shorthand  |

-We will run tests on as many of these as possible, in a matrix with each supported major version of `faraday`,
-which means 0.17.3+ (as `f0`), 1.10.x (as `f1`), 2.2.x (as `f2`).
-
-Discrete versions of `faraday` to test against, as of 2022.02.19, with minimum version of Ruby for each:
-
-* 2.2.0, Ruby >= 2.6
-* 1.10.0, Ruby >= 2.4
-* 0.17.4, Ruby >= 1.9

-# Changelog
-All notable changes to this project will be documented in this file.
-
-The format (since v2) is based on [Keep a Changelog v1](https://keepachangelog.com/en/1.0.0/),
-and this project adheres to [Semantic Versioning v2](https://semver.org/spec/v2.0.0.html).

-## Unreleased
-### Added
-### Changed
-### Fixed
-### Removed
-
-## [2.0.7] - 2022-08-22
-### Added
-- [#629](https://github.com/oauth-xx/oauth2/pull/629) - Allow POST of JSON to get token (@pboling, @terracatta)
-
-### Fixed
-- [#626](https://github.com/oauth-xx/oauth2/pull/626) - Fixes a regression in 2.0.6. Will now prefer the key order from the lookup, not the hash keys (@rickselby)
-  - Note: This fixes compatibility with `omniauth-oauth2` and AWS
-- [#625](https://github.com/oauth-xx/oauth2/pull/625) - Fixes the printed version in the post install message (@hasghari)
-
-## [2.0.6] - 2022-07-13
-### Fixed
-- [#624](https://github.com/oauth-xx/oauth2/pull/624) - Fixes a [regression](https://github.com/oauth-xx/oauth2/pull/623) in v2.0.5, where an error would be raised in refresh_token flows due to (legitimate) lack of access_token (@pboling)
-
-## [2.0.5] - 2022-07-07
-### Fixed
-- [#620](https://github.com/oauth-xx/oauth2/pull/620) - Documentation improvements, to help with upgrading (@swanson)
-- [#621](https://github.com/oauth-xx/oauth2/pull/621) - Fixed [#528](https://github.com/oauth-xx/oauth2/issues/528) and [#619](https://github.com/oauth-xx/oauth2/issues/619) (@pboling)
-  - All data in responses is now returned, with the access token removed and set as `token`
-    - `refresh_token` is no longer dropped
-    - **BREAKING**: Microsoft's `id_token` is no longer left as `access_token['id_token']`, but moved to the standard `access_token.token` that all other strategies use
-  - Remove `parse` and `snaky` from options so they don't get included in response
-  - There is now 100% test coverage, for lines _and_ branches, and it will stay that way.

-- [#312](https://github.com/oauth-xx/oauth2/pull/312) - **BREAKING**: Set `:basic_auth` as default for `:auth_scheme` instead of `:request_body`. This was default behavior before 1.3.0. (@tetsuya, @wy193777)

-  - Original keys will still work as previously, in most scenarios, thanks to `rash_alt` gem.
-  - However, this is a _breaking_ change if you rely on `response.parsed.to_h`, as the keys in the result will be camel case.
-  - As of version 2.0.4 you can turn key transformation off with the `snaky: false` option.
