How do I get publish_actions permission with Facebook - facebook

Question

I follow a tutor for connection with Facebook which uses the following code to connect to Facebook successfully.
The code follows -
FB.Event.subscribe('auth.authResponseChange', function (response) {
if (response.status === 'connected') {
// the user is logged in and has authenticated your
// app, and response.authResponse supplies
// the user's ID, a valid access token, a signed
// request, and the time the access token
// and signed request each expire
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
// TODO: Handle the access token
// Do a post to the server to finish the logon
// This is a form post since we don't want to use AJAX
var form = document.createElement("form");
form.setAttribute("method", 'post');
form.setAttribute("action", 'loadMainPage.ashx');
var field = document.createElement("input");
field.setAttribute("type", "hidden");
field.setAttribute("name", 'accessToken');
field.setAttribute("value", accessToken);
form.appendChild(field);
document.body.appendChild(form);
form.submit();
} else if (response.status === 'not_authorized') {
// the user is logged in to Facebook,
// but has not authenticated your app
} else {
// the user isn't logged in to Facebook.
}
});
};
How can I ask for publish_actions permission ?

What platform are you using? See Facebook's official docs.
An excerpt:
Requesting permissions
Each type of login flow has its own method of requesting these permissions:
Web login with the JavaScript SDK uses a scope option with the FB.login function call.
Other types of web login should add the scope parameter to the Login
dialog URL that they redirect to.
Android login uses the setReadPermissions and setPublishPermissions
on the LoginButton class.
iOS login uses the readPermissions and publishPermissions properties
in the FBLoginView class.
