JSONObject vs JSONArray Swift - json

Question

Im trying to do a PUSH HTTP Request and im getting an error describing that i need to supply a JSON Array and not a JSONObject, how do i create an Array from my single object, is it possible to do so?
func printdata(){
let myJsonDict: [String:AnyObject] = [
"action": "Websites",
"method":"school_webpage",
"tid":2,
"data":["schoolId":14273],
"type":"rpc"
]
do{
let jsonObject = try NSJSONSerialization.dataWithJSONObject(myJsonDict, options: NSJSONWritingOptions.PrettyPrinted)
HTTPPostJSON("http://wwww.oncoursesystems.com/json.axd/direct/router", data:jsonObject ) { (response, error) -> Void in
print(response);
}
}
catch{
}
}
func HTTPsendRequest(request: NSMutableURLRequest, callback: (String, String?) -> Void) {
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
(data, response, error) -> Void in
if (error != nil) {
callback("", error!.localizedDescription)
} else {
callback(NSString(data: data!, encoding: NSUTF8StringEncoding)! as String, nil)
}
}
task.resume()
}
func HTTPPostJSON(url: String, data: NSData, callback: (String, String?) -> Void) {
let request = NSMutableURLRequest(URL: NSURL(string: url)!)
request.HTTPMethod = "POST"
request.addValue("application/json",forHTTPHeaderField: "Content-Type")
request.addValue("application/json",forHTTPHeaderField: "Accept")
request.HTTPBody = data
HTTPsendRequest(request, callback: callback)
}
My method call
override func viewDidLoad() {
super.viewDidLoad()
searchController.searchResultsUpdater = self
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
searchController.searchBar.sizeToFit()
definesPresentationContext = true
self.tableView.tableHeaderView = searchController.searchBar
names = HtmlController.loadData() as NSArray as! [String]
names.removeAtIndex(0)
clean()
refreshController = UIRefreshControl()
refreshController.addTarget(self, action: #selector(WebpageController.refresh(_:)), forControlEvents: UIControlEvents.ValueChanged)
self.tableView.addSubview(refreshController)
printdata()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}

Do you mean a POST request?
This works for me:
func HTTPPostJSON(url: String, data: AnyObject, callback: (String, String?) -> Void) {
let request = NSMutableURLRequest(URL: NSURL(string: url)!)
request.HTTPMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(data, options: [])
HTTPsendRequest(request, callback: callback)
}
Note the method signature, pass your data as ["String": AnyObject] and handle the serialization inside the HTTPPostJSON method. I think part of what's wrong might be related to passing formatted json (when using the pretty options).
Edit:
Based on your comments, have you updated your print method to cater for the new method signature? it should be something along the lines of:
func printdata(){
let myJsonDict: [String:AnyObject] = [
"action": "Websites",
"method":"school_webpage",
"tid":2,
"data":["schoolId":14273],
"type":"rpc"]
HTTPPostJSON("http://wwww.oncoursesystems.com/json.axd/direct/router", data:myJsonDict) {
(response, error) -> Void in
print(response);
}
}
