Imgur extends OAuth2Provider
in package

Application

implements CSRFToken, TokenRefresh

Imgur OAuth2

Note: imgur sends an "expires_in" of 315360000 (10 years!) for access tokens, but states in the docs that tokens expire after one month. Either manually saving the expiry with the token to trigger auto refresh or manually refreshing via the refreshAccessToken() method is required.

Interfaces

CSRFToken: Specifies the methods required for the OAuth2 CSRF token validation ("state parameter")
TokenRefresh: Indicates whether the provider is capable of the OAuth2 token refresh.

                    getTokenResponseData(ResponseInterface $response) : array<string|int, mixed>

we don't bother checking the content type here as it's sometimes vendor specific, not set or plain wrong: the spec mandates a JSON body which is what almost all providers send - weird exceptions:

mixcloud sends JSON with a "text/javascript" header
deezer sends form-data with a "text/html" header (???)
silly amazon sends gzip compressed data... (handled by decodeJSON)

$response : ResponseInterface

Return values

array<string|int, mixed>
