ios - 如何快速从 NSHTTPCookies 获取服务器 jwt？

Question

我使用 Alamofire 从服务器获得响应 cookie。我的代码如下:

    let urlPath :String = LOGIN_URL

    Alamofire.request(.POST, urlPath, parameters: parameters).responseJSON { response in

        print(response)

        if let
            headerFields = response.response?.allHeaderFields as? [String: String],
            URL = response.request?.URL
        {
            let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(headerFields, forURL: URL)
            print(cookies)

        }
    }

第 9 行:print(cookies) 输出:

[NSHTTPCookie

这里，值是我期望从服务器发送的 jwt。

但是不能像cookies.value或者cookies["value"]那样访问。那么，要解码 jwt 我怎样才能访问 value ？

Answer 1

好的。我已经解决了这个问题。

我需要将 cookie 作为 NSObject 获取，然后从中提取值。

   let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(headerFields, forURL: URL) as NSObject
   let jwtfromCookie = (cookies.valueForKey("value"))!
   print(jwtfromCookie)
