GET-Evidence

The OAuth2 needs credentials setup with Google.

From Tom's post: https://arvados.org/blogs/30

Step 1. Tell Google Developer Console how to recognize your web application.¶

• Visit https://console.developers.google.com/project
• Click “Create Project”. Give it a name and ID.
• In the new project, click “APIs” in the “APIs & auth” section in the left nav.
• Find “Google+ API” in the big list and enable it.
• Click “Credentials” in the “APIs & auth” section in the left nav.
• Under OAuth, click the “Create a new Client ID” button. In the dialog:
• Application type: Web application
• Authorized Javascript origins: https://your-app.example.com/
• Authorized redirect URIs: https://your-app.example.com/google-oauth2.php
• Yes, you can use stuff like “localhost:1234” in both of these fields, for testing.
• Click “Create Client ID”
• You should have a “Client ID for web application” table on the right.
• Copy the client ID and client secret. You’ll need those soon.
