There are a few ways to do it. Personally I would use the Javascript SDK. Another way is to update your Facebook App settings (using Facebook Developer App) to require users to permit Extended Permissions 'publish_stream'.

Below is code using the Javascript SDK FB.api function:

FB.login(function(response) {
  if (response.authResponse) {
      // user is logged in and granted some permissions.
      console.log("user is logged in and granted some permissions.")
  } else {
    // User cancelled login or did not fully authorize.
    console.log("he failed to login or something")
  }
}, {scope:'publish_stream'});

Inside scope: you can put a comma-separated string of permissions, if you want to ask for multiple.
