swift – Alamofire请求cookies

我是初学者,我无法弄清楚如何使用Alamofire制作.GET请求(但需要进行autenthication).我设法用其他Web服务(登录)执行此操作,因为它需要参数参数：

parameters = [
 "username" : username
"password" : password 
]

然后：

Alamofire.request(.POST,loginUrl,parameters: parameters).responseJSON { (request,response,data,error) -> Void in

     //handling the response       
}

在回复标题中我得到一些信息：

[transfer-encoding: Identity,Server: Nginx/1.4.1,Content-Type: application/json,P3P: policyref="http://www.somewebpage.com",CP="NON DSP COR CURa TIA",Connection: keep-alive,Date: Sun,08 Mar 2015 13:49:20 GMT,vary: Accept-Encoding,Cookie,Set-Cookie: sessionid=5xeff47e65f674a4cc5b2d54f344304b; Domain=.somedomain.com; Path=/,tbauth=1; Domain=.somedomain.com; Path=/,content-encoding: gzip]

它的类型为[NSObject：AnyObject]

如何将该信息存储在NSURLDefaults中并准备有效的请求参数(cookie)？我需要所有字段还是只需要Set-Cookie？

我试过手动设置参数：

parameters = [
 "Cookie" : "sessionid=5xeff47e65f674a4cc5b2d54f344304b; Domain=.somedomain.com; Path=/,tbauth=1; Domain=.somedomain.com; Path=/"
]

但它确实返回错误NSURLErrorDomain -1017(NSURLErrorCannotParseResponse)

感谢所有回复.

let URL = NSURL(string: query)!
let mutableurlRequest = NSMutableuRLRequest(URL: URL)
mutableurlRequest.HTTPMethod = "GET"

let prefs = NSUserDefaults.standardUserDefaults()
let cookie = prefs.valueForKey("COOKIE") as String

mutableurlRequest.setValue(cookie,forHTTPHeaderField: "Cookie")

Alamofire.request(mutableurlRequest).responseJSON { (request,error) -> Void in

     //handling the response       
}
