How to get response headers when using Alamofire in Swift?

Question

I\'m using Alamofire for my Rest (POST) request and getting JSON response seamlessly. But i can access only response body. I want to get response headers. Isn\'t it possible

Answer 1

As response is of NSHTTPURLResponse type, you should be able to get the headers as followed:

response.allHeaderFields

Answer 2

Here is how to access the response headers in Swift 3:

Alamofire.request(.GET, requestUrl, parameters:parameters, headers: headers)
   .responseJSON { response in
   if let headers = response.response?.allHeaderFields as? [String: String]{
      let header = headers["token"]
      // ...
   }
}

Answer 3

This code gets response header in Swift 4.2

Alamofire.request(pageUrlStr, method: .post, parameters: Parameter, encoding: URLEncoding.httpBody, headers: nil).responseJSON
            { response in
                //to get JSON return value
                if let ALLheader = response.response?.allHeaderFields  {
                    if let header = ALLheader as? [String : Any] {
                        if let cookies = header["Set-Cookie"] as? String {
                            UserDefaults.standard.set(cookies, forKey: "Cookie")
                        }
                    }
                }
}
