Can't upload image to server swift - swift

Question

I'm trying to upload an image to the server. As for now, I get an error response which checks if name='image', and the error means that it's not. The line where I set it is this:
body.appendString("Content-Disposition: form-data; name='image'; filename='test.jpg'")
my full code of the POST request is this: I do get a 200 and the only problem is with the name parameter which I really can't figure out.
func imageUploadRequest()
{
let stringUrl = "http://88.162.41.55/app_backend/public/api/v1/image?_r=1836486547600309"
let URL = NSURL(string: stringUrl.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)!
let request = NSMutableURLRequest(URL: URL)
request.HTTPMethod = "POST";
request.setValue("Bearer \(jwtToken)", forHTTPHeaderField: "Authorization")
let boundary = generateBoundaryString()
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let imageData = UIImageJPEGRepresentation(image, 1)
if(imageData == nil) {
print("image data is nil")
return
}
let body:NSMutableData = NSMutableData()
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name='image'; filename='test.jpg'")
body.appendString("Content-Type: image/jpg")
body.appendData(imageData!)
body.appendString("\r\n")
body.appendString("--\(boundary)--\r\n")
request.HTTPBody = body
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}
let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print(" response = \(responseString!)")
do {
let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary
print("json", json)
} catch {
print("bad things happened")
}
}
task.resume()
}
Any ideas? Thank you so much!!

Sample NSURLSession
func getMetaData(lePath:String, completion: (string: String?, error: ErrorType?) -> Void) {
// **** get_metadata ****
let request = NSMutableURLRequest(URL: NSURL(string: "https://api.dropboxapi.com/2/files/get_metadata")!)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
request.addValue("Bearer ab-blah", forHTTPHeaderField: "Authorization")
request.addValue("application/json",forHTTPHeaderField: "Content-Type")
request.addValue("path", forHTTPHeaderField: lePath)
let cursor:NSDictionary? = ["path":lePath]
do {
let jsonData = try NSJSONSerialization.dataWithJSONObject(cursor!, options: [])
request.HTTPBody = jsonData
print("json ",jsonData)
} catch {
print("snafoo alert")
}
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
if let error = error {
completion(string: nil, error: error)
return
}
let strData = NSString(data: data!, encoding: NSUTF8StringEncoding)
//print("Body: \(strData)\n\n")
do {
let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions.MutableContainers);
completion(string: "", error: nil)
} catch {
completion(string: nil, error: error)
}
})
task.resume()
}
