Oauth

Middleware for token authentication

Available middleware:

• FaradayMiddleware::OAuth
• FaradayMiddleware::OAuth2

Example use (OAuth 2):

## in Faraday 0.8 or above:
connection = Faraday.new('http://example.com/api') do |conn|
  conn.request :oauth2, 'token'
  conn.adapter Faraday.default_adapter
end

This will cause the 'token' to be inserted in both the query params (as access_token) and headers (as Token token=<token_value>).

As of FaradayMiddleware 0.11, you can specify the token_type option as :bearer:

connection = Faraday.new('http://example.com/api') do |conn|
  conn.request :oauth2, 'token', token_type: :bearer
  conn.adapter Faraday.default_adapter
end

This will cause the token to be inserted ONLY as a header (as Bearer <token_value>), which is more standard-compliant.

DEPRECATION WARNING

Inserting the token as a parameter is now considered a security issue, therefore the next major release of Faraday will only add tokens on headers.
