了解Laravel和Cookie

Question

This is the first time I'm working with both cookies and Laravel. I'm trying to store a simple value, sectionID , and retrieve it for the user so that they can continue working from their last visited section. If there is no saved value, I want to return 0.

Server side routes:

Route::get('cookieget', function() {
    return Cookie::get('sectionID', 0);
});

Route::post('cookieset', function() {
     Cookie::make('sectionID', Input::get('sectionID'), 60*24);
});

Client side is quite complex but these are the relevant parts:

UserController.js

function UserController(userID) {
    var outer = this;

    ...

    this.setCookie = function(maxUserSectionID) {

        $.ajax({
            type: 'POST',
            url: "cookieset",
            data: {
                sectionID: maxUserSectionID
            },
            success: function(data) {
                console.log("Set max sectionID cookie to " + maxUserSectionID);
            }
        });
    }

    this.getSectionIDFromCookie = function() {
        $.ajax({
            type: 'GET',
            url: "cookieget",
            async: false,
            success: sectionController.handleNewSection
        });


    }
}

SectionController.js

function SectionController(editor, lessonNr)
{

    // setup initial data
    // the 0-based index of the current section
    this.currentSection = null;
    // the furthest the user has reached in this lesson
    this.maxSection = 0;
...

    // methods

    this.nextSection = function() {

        if (outer.currentSection > outer.maxSection) {
            outer.maxSection = outer.currentSection;
            userController.setCookie(outer.lessonJSON['sections'][outer.maxSection]['sectionID']);
        }

    ...
    };

    ...

    this.checkCookie = function() {
        userController.getSectionIDFromCookie();
    }

    this.handleNewSection = function(newSectionID) {
        alert(newSectionID);
        outer.currentSection = parseInt(newSectionID);
...
    }

    // called from outside as "constructor"
    this.setup = function() {
        ...
    outer.checkCookie();
    }

}

First of all, my main problem is that the cookie always returns 0, even though I'm sure that setCookie is called successfully.

Second, I'm wondering if there's more elegant ways of doing it? I assume now it puts a lot of load on the server if isers are moving through sections too quickly.

Must return a response with cookie to set your cookie properly:

Route::post('cookieset', function() {
    $response = Response::make('Hello World');

    return $response->withCookie(Cookie::make('sectionID', Input::get('sectionID'), 60*24););
});
