I have a function that includes a responseObject in it's completion handler. At the moment this returns the json body when I call it, along with any errors.
Some parts of the API I am using however, don't return any data in the response body, they just return a response (200, 404, etc...)
I was thinking about appending the response inside the empty json object that is getting returned, then realised that would be silly and it would probably be better if I returned the NSHTTPURLResponse as well, but everything I have found just explains how to return the responseObject along with the error...
This is the function that returns the completion handler:
func makePostRequest(url : String, params : AnyObject, completionHandler: (responseObject: NSHTTPURLResponse, JSON?, error: NSError?) -> ()) -> Request? {
println("params = \(params)")
return Alamofire.request(.POST, url, parameters: params as? [String : AnyObject], encoding: .JSON)
.responseJSON { (request, response, data, error) in completionHandler(
//This is wrong
response: response as? NSHTTPURLResponse,
responseObject:
{
println("Request is \(request)")
println("Response is \(response)")
println("Data is \(data)")
println("Error is \(error)")
//Append the response to this JSON object?
//
var json:JSON = [:]
if let anError = error
{
println(error)
}
else if let data: AnyObject = data
{
json = JSON(data)
}
//probably better to return the two...
//
return (response, json)
}(),
error: error
)
}
}
And this is how its used:
networking.makePostRequest(documentUrl, params: docParams) { response, json, error in
println("response is: \(response)")
println("document json: \(json)")
println("document error: \(error)")
}
I've added in the 'response' bits to all the bits of code, i'm sure this is possible? just not sure how to achieve it..
For anyone stuck trying to figure out how to return stuff this way, I solved it like this:
func makePostRequest(url : String, params : AnyObject, completionHandler: (httpResponse: NSHTTPURLResponse, responseObject:JSON?, error: NSError?) -> ()) -> Request? {
println("params = \(params)")
return Alamofire.request(.POST, url, parameters: params as? [String : AnyObject], encoding: .JSON)
.responseJSON { (request, response, data, error) in completionHandler(
//This is wrong
httpResponse: response!,
responseObject:
{
println("Request is \(request)")
println("Response is \(response)")
println("Data is \(data)")
println("Error is \(error)")
//Append the response to this JSON object?
//
var json:JSON = [:]
if let anError = error
{
println(error)
}
else if let data: AnyObject = data
{
json = JSON(data)
}
return json
}(),
error: error
)
}
}
and then calling it like this:
networking.makePostRequest(workDocumentUrl, params: params) { response, json, error in
if response.statusCode == 200{
//do something
}
println("json: \(json)")
println("error: \(error)")
}
