Oauth2 Client

This library is designed to simplify consuming Oauth2 enabled REST Services. It wraps a restclient and takes care of reauthenticating expired access_tokens when needed.

Flows

Implemented flows are:

• Client Credentials Grant
• Resource Owner Password Credentials Grant

Example

Retrieve a client with access_token using Password Credentials Grant

1> oauth2c:retrieve_access_token(<<"password">>, <<"Url">>, <<"Uid">>, <<"Pwd">>).
{ok, Headers, Client}

Retrieve a client with access_token using Client Credentials Grant

2> oauth2c:retrieve_access_token(<<"client_credentials">>, <<"Url">>, <<"Client">>, <<"Secret">>).
{ok, Headers, Client}

The Opaque Client object is to be used on subsequent requests like:

3> oauth2c:request(get, json, <<"Url">>, [200], Client).
{{ok, Status, Headers, Body} Client2}

See restclient for more info on how requests work.
