Good morning, I looked for several sites a way to do a POST request for a server, found several ways and tried all of them, but none worked. I can receive the data from the page and even send GET variables in the URL, but POST variables are simply not sent.

func teste(){

    var request = NSMutableURLRequest(URL: NSURL(string: "http://minhaurl/efetuarLogin.php?variavel=teste&get=valor")!)

    var session = NSURLSession.sharedSession()

    request.HTTPMethod = "POST"

    var params = ["CPF":"00000000000", "senha":"12345678"] as Dictionary

    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")

    var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in

        var strData = NSString(data: data, encoding: NSUTF8StringEncoding)
        var err: NSError?

        var json = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error: &err) as NSDictionary

        if((err) != nil) {

            println(err!.localizedDescription)

        } else {

            println("JSON: \(json)")

        }

    })

    task.resume()

}

In the PHP page I try to access the variables through $ _POST, $ _GET and even $ _REQUEST, only GET variables are received on the server.

Can anyone tell me what may be going wrong? Thanks in advance.

Because the JSON header, and so on, do not expect to receive your CPF and password ) as $_POST['senha'] for example, since it was not a form that was sent.

You need to get the "body" of the request, which is a JSON , decode and then yes you will have the variables you need. On the server side, with PHP try something like this:

$inputJSON = file_get_contents('php://input');
$input = json_decode($inputJSON, TRUE);

// $input['CPF'], $input['senha']

No iOS is all correct. See if that solves your question.

In the implementation you posted does not contain errors, it is just a very simple request.

Try removing the parameters from your URL in the request, as it may be being processed by the server and bypassing your httpBody.
