2.4 – OAuth2

First, save your OAuth2 provider configuration into a JSON file, for example:

{
  "providers" : [{
    "name" : "Google",
    "client_id" : "650561938988-t2r66k1ms3hpoi3k1e2g7l2adlarau8s.apps.googleusercontent.com",
    "client_secret" : "-D-nhxWn2E97tZWWLg5IQ6Ak",
    "request_uri" : "https://accounts.google.com/o/oauth2/auth",
    "redirect_uri" : "http://localhost/oauth2callback",
    "access_token_uri": "https://accounts.google.com/o/oauth2/token",
    "scope": "openid email"
  },
  {
    "name" : "Live",
    "client_id" : "0000000040133A31",
    "client_secret" : "p9WwBr2Pyrq6mtaeZCwTSwqbIF39Br3Z",
    "request_uri" : "https://login.live.com/oauth20_authorize.srf",
    "redirect_uri" : "http://www.remotespark2.com/oauth2callback",
    "access_token_uri": "https://login.live.com/oauth20_token.srf",
    "scope": "wl.emails",
    "profile_uri": "https://apis.live.net/v5.0/me"
  }]
}

Second, specify the position of this file in gateway.conf:

oauth2 = \\user\\local\bin\\SparkViewGateway\\oauth2.json
