Assuming I have a user logged in to Facebook (Cookies are saved in the browser's cache), what is the simplest way to get its access token? I'm experimenting with Facebook's Graph API, and I don't want to bother with creating an application in order to get access tokens (at least not now).
If I remember correctly, a few days ago I went to http://graph.facebook.com/me on my browser (while being logged in), which redirected me to http://graph.facebook.com/me?access_token=..., but now I get that instead (and no redirection):
{
"error": {
"type": "OAuthException",
"message": "An active access token must be used to query information about the current user."
}
}
Unfortunately, I couldn't rely on previously answered questions, since I strongly believe things changed very recently.
All the docs you're going to need are here: https://developers.facebook.com/docs/authentication/
If you just want a single access token for yourself to test some things in the API, you could use the Graph API Explorer ( https://developers.facebook.com/tools/explorer ) to generate an access token for you for that app and copy/paste it to your code.
Be sure to include the 'offline_access' permission to get a token which won't quickly expire.
