Mapping allHeaderFields in AlamofireObjectMapper response - ios

Question

I am using AlamofireObjectMapper
and response from my server is in JSON but it also include some key in the headers
Alamofire.request(URL).responseObject { (response: DataResponse<MyMappable>) in
let weatherResponse = response.result.value
print(weatherResponse?.location)
}
and my map able class is like this
class MyMappable: Mappable {
var location: String?
required init?(map: Map){
}
func mapping(map: Map) {
location <- map["location"]
}
}
all of the above code is working but my problem is I want to map some value is header, I can get these header in the response only
let allHeaders = response.response?.allHeaderFields
if let headers = allHeaders as? [String: String], let someValue = headers["key"]
{
print("my value is: \(someValue)")
}
but I want to map it in the MyMappable class, is it possible ?

Answer 1

I could not find a way to map header Fields with payload
what I could find was, we can get all header fields from response and store it in our class in two ways.
first one is like this
Alamofire.request(URL).responseObject { (response: DataResponse<MyMappable>) in
let myMappable = response.result.value
myMappable.allHeaderFields = response.response?.allHeaderFields
print(myMappable?.location)
}
and the second way (which one used by me) if you are using generic class as parent then you can cast your response like blow
Alamofire.request(URL).responseObject { (response: DataResponse<MyMappable>) in
let myMappable = response.result.value
if let genericResp = myMappable as? GenericResponse<AnyGeneric> {
genericResp.mHeaders = response.response?.allHeaderFields
}
}
