Saving cookies in Alamofire (Swift)

I want to store my cookies so that when i reopen the application i can restore the ones stored in the previous instance. To initialize alamofire i use:

let manager = Alamofire.Manager.sharedInstance

And my code to load cookies is:

let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(headerFields, forURL: URL)
Alamofire.Manager.sharedInstance.session.configuration.HTTPCookieStorage?.setCookies(cookies, forURL: URL, mainDocumentURL: nil)

But when i reboot the phone it forgets all the cookies.

Solution

  • 1.Add method to save cookies in NSUserDefaults

    func setCookie (cookie:NSHTTPCookie)
{        
    NSUserDefaults.standardUserDefaults().setObject(cookie.properties, forKey: "kCookie")
    NSUserDefaults.standardUserDefaults().synchronize()
}

    2.And method to retrieve them after reboot

    func getCookie () -> NSHTTPCookie
{
    let cookie = NSHTTPCookie(properties: NSUserDefaults.standardUserDefaults().objectForKey("kCookie") as! [String : AnyObject])
    return cookie!
}

    3.Retrieve cookies from request in Alamofire 

    let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(response.response?.allHeaderFields as! [String: String], forURL: (response.response?.URL!)!)

//Save method
setCookie(cookies.first!)

    4.Use getCookie method after reboot before any request

    NSHTTPCookieStorage.sharedHTTPCookieStorage().setCookie(getCookie())
