SWIFT and PHP exchange with JSON - php

Question

iam using swift function to send POST query to php script
func post_retJSON_inJSON(params : Dictionary<String, String>,tourl:String)
{
let myUrl = NSURL(string: tourl);
let request = NSMutableURLRequest(URL:myUrl!);
request.HTTPMethod = "POST";
var err: NSError?
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let task = NSURLSession.sharedSession().dataTaskWithRequest(request)
{
data, response, error in
if error != nil
{
println("error=\(error)")
return
}
// You can print out response object
println("response = \(response)")
// Print out response body
let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
println("responseString = \(responseString)")
//Let's convert response sent from a server side script to a NSDictionary object:
var err: NSError?
var myJSON = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error:&err) as? NSDictionary
if let parseJSON = myJSON {
// Now we can access value of First Name by its key
var firstNameValue = parseJSON["firstName"] as? String
println("firstNameValue: \(firstNameValue)")
}
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
task.resume()
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
}
With this php
$firstName= $_POST["firstName"];
$lastName = $_POST["lastName"];
$returnValue = array("firstName"=>$firstName, "lastName"=>$lastName);
// Send back request in JSON format
echo json_encode($returnValue);
AND then in swift i have a response
Optional({"firstName":null,"lastName":null})
I think i already try everything but I cant get in PHP parametres sended by SWIFT query. Help me please to figureout it!!!

Answer 1

solved with this php and the same swift as in top
// Read request parameters
$postdata = json_decode(file_get_contents("php://input"),TRUE);
$firstName= $postdata["firstName"];
$lastName = $postdata["lastName"];
// Store values in an array
$returnValue = array("firstName"=>$firstName, "lastName"=>$lastName);
// Send back request in JSON format
echo json_encode($returnValue);
