Запрос на загрузку изображений Swift с помощью camfind ⇐ IOS

[Anonymous]

Привет, я пытаюсь использовать Mashape API CamFind для загрузки запроса изображения, но не знаю, как это сделать. Camfind хочет:

• многоформальный закодированный запрос
• заголовок, содержащий ключ
• параметры: image_request[locale] и image_request[image]

Я застрял на этом очень долго, буду благодарен за любую помощь, получаю ошибку 400
Вот мой код :
func post(){
var TWITTERFON_FORM_BOUNDARY:String = "AaB03x"
let url = NSURL(string: "https://camfind.p.mashape.com/image_requests")!
var request:NSMutableURLRequest = NSMutableURLRequest(URL: url, cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 10)
var MPboundary:String = "--\(TWITTERFON_FORM_BOUNDARY)"
var endMPboundary:String = "\(MPboundary)--"
var data:NSData = UIImagePNGRepresentation(imageView.image)
var filename:String = "image request image"
var body:NSMutableString = NSMutableString();
// params

let path = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0] as! NSString
let documentDirectoryPath:NSString = path.stringByAppendingString("items.db")

let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory
let nsUserDomainMask = NSSearchPathDomainMask.UserDomainMask
let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
let imageURL = paths[0].stringByAppendingString("image.png")
UIImagePNGRepresentation(imageView.image).writeToFile(imageURL, atomically: true)

let parameters:NSDictionary = ["focus[x]": "480", "focus[y]": "640","image_request[language]": "en","image_request[locale]": "en_US","image_request[image]": imageURL]

for (key, value) in parameters {
body.appendFormat("\(MPboundary)\r\n")
body.appendFormat("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
body.appendFormat("\(value)\r\n")
}
let parametersNS : NSData = NSKeyedArchiver.archivedDataWithRootObject(parameters)
// image upload
body.appendFormat("%@\r\n",MPboundary)
body.appendFormat("Content-Disposition: form-data; name=\"\(filename)\"; filename=\"pen111.png\"\r\n")
body.appendFormat("Content-Type: image/png\r\n\r\n")
var end:String = "\r\n\(endMPboundary)"
var myRequestData:NSMutableData = NSMutableData();
myRequestData.appendData(body.dataUsingEncoding(NSUTF8StringEncoding)!)

myRequestData.appendData(parametersNS)

myRequestData.appendData(end.dataUsingEncoding(NSUTF8StringEncoding)!)
var content:String = "multipart/form-data; boundary=\(TWITTERFON_FORM_BOUNDARY)"
request.setValue(content, forHTTPHeaderField: "Content-Type")
request.setValue("\(myRequestData.length)", forHTTPHeaderField: "Content-Length")
request.HTTPBody = myRequestData
request.HTTPMethod = "POST"
request.setValue("9hcyYCUJEsmsh4lNTgpgVX1xRq0Ip1uogovjsn5Mte0ONVBtes", forHTTPHeaderField: "X-Mashape-Key")
let session = NSURLSession.sharedSession()
let dataTask = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
println(error)
} else {
let httpResponse = response as? NSHTTPURLResponse
let statusCode = (response as? NSHTTPURLResponse)?.statusCode ?? -1
let statusDescripton = httpResponse?.description

println(httpResponse)

}
})

dataTask.resume()

}
