谷歌与oauth 2

I am trying to connect with google via oauth V2

I make http request

https://accounts.google.com/o/oauth2/token?code=4/55Ji5pVGxrhCUB3yMu6BYdi2qARQ&redirect_uri=https%3A%2F%2Fwww.choozon.net%2Foauth2callback&client_id=408311227080.apps.googleusercontent.com&scope=https%3A%2F%2Fmail.google.com%2Fmail%2Ffeed%2Fatom&client_secret=********&grant_type=authorization_code

why the response is

Method Not Allowed     Error 405

HTTP 405 means that you are trying to use a verb that is not allowed by the resource. For example using a POST on a read-only GET resource or PUT on a write resource that only accepts POSTs.
