Send post variables to API

Question

I am trying to send post parameters to my API, it gets four variables :

• labelled
• id_produit
• id_magasin
• Prix

Here's my code:

@IBAction func AddProduct(sender: AnyObject) {
    
    
    let myUrl = NSURL(string: "http://vps43623.ovh.net/yamoinscher/api/products/create_product");let request = NSMutableURLRequest(URL:myUrl!);
    request.HTTPMethod = "POST";
    // Compose a query string
    let postString = "id=123456789&libelle=Florida&id_magasin=1&prix=1500";
    
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding);
    
    
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
    
        data, response, error in
        
        if error != nil
        {
            print("error=\(error)")
            return
        }
        
        // print out response object
        print("response = \(response)")
        
        // Print out response body
        let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
        print("responseString = \(responseString)")
        
  
        }
    task.resume()
    
    }

And when I execute this code I get this response:

response = Optional(<NSHTTPURLResponse: 0x7fadeaf532a0> { URL: http://vps43623.ovh.net/yamoinscher/api/products/create_product } { status code: 200, headers {
Connection = "keep-alive";
"Content-Length" = 0;
"Content-Type" = "application/x-www-form-urlencoded";
Date = "Thu, 28 Apr 2016 09:15:09 GMT";
"MS-Author-Via" = DAV;
Server = nginx;
"X-Powered-By" = PleskLin;
} })

responseString = Optional()

The console tells me that there is no variables sent to the api. Can any one help me please?

@IBAction func AddProduct(sender: AnyObject) {


        let myUrl = NSURL(string: "http://vps43623.ovh.net/yamoinscher/api/products/create_product");let request = NSMutableURLRequest(URL:myUrl!);
        request.HTTPMethod = "POST";
        // Compose a query string
        let postString = "id=123456789&libelle=Florida&id_magasin=1&prix=1500";
        let postLength = String(postData.length)

        request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding);

        request.setValue(postLength, forHTTPHeaderField: "Content-Length")
        request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
        request.setValue("application/json", forHTTPHeaderField: "Accept")

        let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {

            data, response, error in

            if error != nil
            {
                print("error=\(error)")
                return
            }

            // print out response object
            print("response = \(response)")

            // Print out response body
            let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
            print("responseString = \(responseString)")


            }
        task.resume()

        }
