var response: NSURLResponse?
var error: NSError?

// create some JSON data and configure the request
let jsonString = "json=[{\"str\":\"Hello\",\"num\":1},{\"str\":\"Goodbye\",\"num\":99}]"
request.HTTPBody = jsonString.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")

// send the request
NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)

// look at the response
if let httpResponse = response as? NSHTTPURLResponse {
    println("HTTP response: \(httpResponse.statusCode)")
} else {
    println("No HTTP response")
}
