Swift2 NSHTTPCookie厨师与负责人字段

调用API时，我收到以下响应：

<NSHTTPURLResponse: 0x7f96f0510f80> { URL: https://insula.magister.net/api/sessie } { status code: 201, headers {
    "Cache-Control" = "max-age=120, private";
    "Content-Length" = 0;
    Date = "Thu, 30 Jul 2015 17:27:11 GMT";
    "Set-Cookie" = "SESSION_ID=c8714acb-22f8-4295-90ee-82e9469890e1; domain=insula.magister.net; path=/api; secure; httponly";
    "Strict-Transport-Security" = "max-age=31536000";
    Vary = "Accept-Encoding,Cookie";
    "X-Frame-Options" = DENY;
} }

但是我不能让

cookiesWithResponseHeaderFields

工作，我应该传递一个

[String:String]

数组作为第一个参数，但是响应似乎不符合要求

let cookies=NSHTTPCookie.cookiesWithResponseHeaderFields（HTTPResponse.allHeaderFields，forURL:url）

但是作为

HTTPResponse.allHeaderFiles

是

[NSObject:AnyObject]

类型的数组，它不能满足

[String:String]

参数类型。 谁知道该怎么办呢？

有一个带一个的

您应该将

allHeaderFields

属性强制转换为所需的类型，即

[String:String]

，如下所示：

  let foundCookies: [NSHTTPCookie]?
  if let responseHeaders = HTTPResponse.allHeaderFields as? [String:String] {
    foundCookies = NSHTTPCookie.cookiesWithResponseHeaderFields(responseHeaders, forURL:url)
  }

  let foundCookies: [NSHTTPCookie]?
  if let responseHeaders = HTTPResponse.allHeaderFields as? [String:String] {
    foundCookies = NSHTTPCookie.cookiesWithResponseHeaderFields(responseHeaders, forURL:url)
  }
