Synopsis

See full example: cmd/groupcache-oauth2-client-example/main.go.

import "github.com/udhos/groupcache_oauth2/clientcredentials"

// initialize groupcache and return workspace.
// see the example client for an implementation of this function.
groupcacheWorkspace := startGroupcache()

options := clientcredentials.Options{
    TokenURL:                        tokenURL,
    ClientID:                        clientID,
    ClientSecret:                    clientSecret,
    Scope:                           scope,
    HTTPClient:                      http.DefaultClient,
    GroupcacheWorkspace:             groupcacheWorkspace,
}

client := clientcredentials.New(options)

// use client to make requests, it will automatically fetch and cache tokens.
// client.Do automatically manages token retrieval, caching, and background refreshing.
resp, errDo = client.Do(req)
