Facebook：使用getAccessToken方法获取应用程序访问令牌

Question

On facebook documentation page, there is written:

Facebook::getAccessToken()

Get the current access token being used by the SDK. This may be a user access token or an application access token. See the permissions page for more information on access tokens.

But there is no explanation how to force the method to return app token, not the user token. It is not exmplained nor on permission page. Cn anybody help, how this method works?

Answer 1

The App access_token is usually just APP_ID|APP_SECRET . In my code, I tend to just do this:

$app_token = APP_ID . '|' . APP_SECRET;
