Question

如果用户删除了我所需要的任何许可,我想将用户转至 o页。

出于某种原因,在我试图从FB.api呼救功能中转出时,以下的法典造成了无休止的漏洞。我如何解决这一问题的想法?

var perms           = [ publish_actions ,  email ,  user_birthday ,  user_location ],
    permsString     = perms.join( , ),
    permissionsUrl  =  https://www.facebook.com/dialog/oauth ;
    permissionsUrl  +=  ?client_id=  + config.facebook.appId;
    permissionsUrl  +=  &redirect_uri=  + encodeURI(canvasUrl);
    permissionsUrl  +=  &scope=  + permsString;

    FB.getLoginStatus(function (response) {

        if (response.status ===  connected ) {

            FB.api( /me/permissions , function(response) {

                // using underscore here...
                var keys = _.keys(response.data[0]),
                    diff = _.difference(perms, keys);

                // send the user through the auth again if they ve removed any of the perms we need
                if (diff.length) {

                    window.location.href = permissionsUrl; // results in an endless redirect loop
                    // window.location.href =  http://randomwebsite.com ; // does redirect successfully!!!!
                }
            });
        }

    }, true);

这是自我这样做以来的一段时期,但从记忆中,我以这样的方式解决了这一问题:

var redirectMe = function (link) {
  window.location.href = link;
};

FB.getLoginStatus(function (response) {
    if (response.status ===  connected ) {
        FB.api( /me/permissions , function(response) {
            if (true) {
                redirectMe( http://www.browsehappy.com );
            }
        });
    }
}, true);
