Be awesome! Feel free to clone and use according to the licence. If you make a useful change that can benefit others, send a pull request! This ensures that one version has all the good stuff and doesn't fall behind.

Code example

See _example/ for a simple webserver using the openID implementation. Also, read the comment about the NonceStore towards the top of that file. The example must be run for the openid-go directory, like so:

go run _example/server.go

App Engine

In order to use this on Google App Engine, you need to create an instance with a custom *http.Client provided by urlfetch.

oid := openid.NewOpenID(urlfetch.Client(appengine.NewContext(r)))

Here is a set of libraries I found on GitHub that could make using this library easier depending on your backends. I haven't tested them, this list is for reference only, and in no particular order:

  • Gacnt/myopenid "A Yohcop-Openid Nonce/Discovery storage replacement", using MySQL.
  • Gacnt/sqlxid "An SQLX Adapter for Nonce / Discovery Cache store"
  • Gacnt/gormid "Use GORM (Go Object Relational Mapping) to store OpenID DiscoveryCache / Nonce in a database"
  • hectorj/mysqlOpenID "MySQL OpenID is a package to replace the in memory storage of discoveryCache and nonceStore."
