What?
This is koa middleware to retrieve information about an authenticated user (the userinfo) given their access token.
See the relevant part of the OpenID specification for details on userinfo.
How to Use
In a koa app, add as middleware:
app.use(userinfo({ site: 'https://login-test.u5auth.com/userinfo' }))
The middleware fails with a status of 401 if no token is available. This can be ignored by setting the option allowMissingOrInvalidToken: true.
How to Run Sample
Check the site in the sample and adjust to your userinfo provider (your OAuth2 / OpenID provider). Then:
npm install
npm run sample
This runs a sample server (on port PORT or 3000), which responds with a text representation of your userinfo, if you call it with a valid access token.
Example call:
export TOKEN=123
curl -v -H "Authorization: Bearer $TOKEN" localhost:3000
