How to issue an access token?

open "https://accounts.google.com/o/oauth2/auth\
?client_id=${GOOGLE_CLIENT_ID}\
&redirect_uri=http://localhost\
&scope=https://www.googleapis.com/auth/calendar\
&response_type=code\
&approval_prompt=force\
&access_type=offline"

curl \
  -d "client_id=${GOOGLE_CLIENT_ID}"\
  -d "client_secret=${GOOGLE_CLIENT_SECRET}"\
  -d "redirect_uri=http://localhost"\
