如何使用Swift从NSURLSession获取cookie?

swift

我有一个NSURLSession调用dataTaskWithRequest以这种方式发送POST请求

func makeRequest(parameters: String, url:String){
    var postData:NSData = parameters.dataUsingEncoding(NSASCIIStringEncoding)!
    var postLength:NSString = String(postData.length )
    var request = NSMutableURLRequest(URL: NSURL(string: url)!)
    var session = NSURLSession.sharedSession()
    request.HTTPMethod = "POST"

    var error:NSError?
    //request.HTTPBody = NSJSONSerialization.dataWithJSONObject(postData, options: nil, error: &error)
    request.HTTPBody = postData
    request.setValue(postLength, forHTTPHeaderField: "Content-Length")
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    request.setValue("application/json", forHTTPHeaderField: "Accept")

    var task = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in

        println("Response:\(response)")

        // Other stuff goes here

})

响应等于:

<NSHTTPURLResponse: 0x7fcd205d0a00> { URL: http://XXX.XXX.XXX:0000/*** } { status code: 200, headers {
    "Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
    Connection = close;
    "Content-Length" = 16;
    "Content-Type" = "application/json; charset=utf-8";
    Date = "Mon, 13 Apr 2015 00:07:29 GMT";
    Expires = "Thu, 19 Nov 1981 08:52:00 GMT";
    Pragma = "no-cache";
    Server = "Apache/2.2.15 (CentOS)";
    "Set-Cookie" = "MYCOOKIEIS=12dsada342fdshsve4lorewcwd234; path=/";
    "X-Powered-By" = "PHP/5.3.14 ZendServer/5.0";
} }

我的问题是我不知道如何获取名称为MYCOOKIEIS的“ Set-Cookie”中的cookie。

我将在用户登录时使用它,因此,如果用户未登录->登录(调用登录api),否则请转到主屏幕并调用其他API。

有人可以帮助我从那里拿走饼干吗?

Swift呈现形式可能类似于:

let task = session.dataTask(with: request) { data, response, error in
    guard
        let url = response?.url,
        let httpResponse = response as? HTTPURLResponse,
        let fields = httpResponse.allHeaderFields as? [String: String]
    else { return }

    let cookies = HTTPCookie.cookies(withResponseHeaderFields: fields, for: url)
    HTTPCookieStorage.shared.setCookies(cookies, for: url, mainDocumentURL: nil)
    for cookie in cookies {
        var cookieProperties = [HTTPCookiePropertyKey: Any]()
        cookieProperties[.name] = cookie.name
        cookieProperties[.value] = cookie.value
        cookieProperties[.domain] = cookie.domain
        cookieProperties[.path] = cookie.path
        cookieProperties[.version] = cookie.version
        cookieProperties[.expires] = Date().addingTimeInterval(31536000)

        let newCookie = HTTPCookie(properties: cookieProperties)
        HTTPCookieStorage.shared.setCookie(newCookie!)

        print("name: \(cookie.name) value: \(cookie.value)")
    }
}
task.resume()
