Swift HTTP POST Request Login - html

Question

Hey I'm trying to figure out this problem for quite some time so now I'm asking you guys for help.
In my Project I'm trying to send a POST request to a website with a login form to access the server.But I somehow don't manage to pass the data.
The website I'm trying to access is https://edu.sh.ch
in the Inspector of my browser I can see it needs a Post method to pass the data :
<form id="form1" name="form1" autocomplete="off" method="post" action="/uniquesigfe5a0f1f915f15b647d0b7a5306be984/uniquesig0/InternalSite/Validate.asp" onsubmit="return(SubmitForm());"></form>
here's my code:
func PostingCredentials(){
let myUrl = NSURL(string: self.manipulatedUrl)
let request = NSMutableURLRequest(URL:myUrl!);
request.HTTPMethod = "POST";
// Compose a query string
let form1 = "user_name=MyUsername&password=MyPassword"
request.HTTPBody = form1.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil
{
println("error=\(error)")
return
}
println("response = \(response)")
// You can print out response object
let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
//
println("responseString = \(responseString)")
}
task.resume()
}
Note that self.manipulateUrl equals to the url which shows up when I log in normally and submit my credentials (https://edu.sh.ch/uniquesigfe5a0f1f915f15b647d0b7a5306be984/uniquesig0/InternalSite/Validate.asp)
The Post Function posts something but the response is always some sort of error page( I'm not getting any error in the code but the response of the server is an error)
So for the end my main question are :
whats the problem with my code
where do I have to send my POST method to,to the login page url or the validation url?
Thanks in advance

Some Problem with your webpage. Something is wrong in web coding. Then also you can try below code :
let form1 = "user_name=MyUsername&password=MyPassword"
let request:NSMutableURLRequest = NSMutableURLRequest(URL: NSURL(string: "https://edu.sh.ch")!)
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-type")
request.HTTPBody = form1.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) { (response:NSURLResponse!, data:NSData!, error:NSError!) -> Void in
var str = NSString(data: data, encoding: NSUTF8StringEncoding)
//var dict = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as! NSArray
}
