error while requesting json in SWIFT + ios - ios

Question

I am requesting some data by json , I am new to SWIFT for iOS so I don't get whats the problem in my code :
var URL="http://X.X.X.X.X/Api/UserManagement/getMobileUser";
var UserId=uname.text;
var pword=passwd.text;
var PostData: NSString = "{\"data\":{},\"action\":\"System\",\"method\":\"getMobileUser\",\"username\":\" mpc01\",\"password\":\"mpc01\",\"type\":\"rpc\",\"tid\":\"144\"}"
let request = NSMutableURLRequest(URL: NSURL(string: URL)!)
request.HTTPMethod = "POST"
let postString = PostData
//var st:NSData = PostData.dataUsingEncoding(NSUTF8StringEncoding)!
// request.HTTPBody = PostData.dataUsingEncoding(NSUTF8StringEncoding)
request.HTTPBody = (postString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
//let data = (postString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil {
println("error=\(error)")
return
}
println("response = \(response)")
let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
println("responseString = \(responseString)")
}
task.resume()
THE response I get is :
response = { URL: http://X.X.X.X/Api/UserManagement/getMobileUser } { status code: 500, headers {
"Cache-Control" = "no-cache";
"Content-Length" = 36;
"Content-Type" = "application/json; charset=utf-8";
Date = "Sat, 03 Jan 2015 06:11:51 GMT";
Expires = "-1";
Pragma = "no-cache";
Server = "Microsoft-IIS/7.5";
"X-AspNet-Version" = "4.0.30319";
"X-Powered-By" = "ASP.NET";
} }
responseString = Optional({"Message":"An error has occurred."})

I had a similar problem trying to POST to MailGun for some automated emails I was implementing in an app.
I was able to get this working properly with a large HTTP response. I put the full path into Keys.plist so that I can upload my code to github and broke out some of the arguments into variables so I can have them programmatically set later down the road.
// Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?
if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
keys = NSDictionary(contentsOfFile: path)
}
if let dict = keys {
// variablize our https path with API key, recipient and message text
let mailgunAPIPath = dict["mailgunAPIPath"] as? String
let emailRecipient = "bar#foo.com"
let emailMessage = "Testing%20email%20sender%20variables"
// Create a session and fill it with our request
let session = NSURLSession.sharedSession()
let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler#<my domain>.com%3E&to=reservations#<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)
// POST and report back with any errors and response codes
request.HTTPMethod = "POST"
let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
if let error = error {
print(error)
}
if let response = response {
print("url = \(response.URL!)")
print("response = \(response)")
let httpResponse = response as! NSHTTPURLResponse
print("response code = \(httpResponse.statusCode)")
}
})
task.resume()
}
The Mailgun Path is in Keys.plist as a string called mailgunAPIPath with the value:
https://API:key-<my key>#api.mailgun.net/v3/<my domain>.com/messages?
Hope this helps!
