Uploading multipart image giving error ios - ios

Question

I am trying to create a multipart request to upload my image. But it's not working as expected. Can some one explain where I am doing wrong.
static func makeImageRequest(_ urlString: String,version:String, method:FYIHTTPMethod,formData:Data?,fileName:String, completionHandler: #escaping (_ dictionary:NSDictionary?, _ error:NSError?) -> Void ) -> URLSessionTask {
let fullURL:String = "https://" + domain + ":8243/fyi/" + version + "/" + urlString
let request = NSMutableURLRequest(url: URL(string: fullURL)!)
request.timeoutInterval = 300
request.httpMethod = method.rawValue
request.setValue("multipart/form-data;boundary=*****", forHTTPHeaderField: "Content-Type")
request.httpBody = formData
let accessToken = FYISession.sharedInstance.getAccessToken()
request.setValue("Bearer \(accessToken)", forHTTPHeaderField: "Authorization")
request.setValue("application/json", forHTTPHeaderField: "Accept")
request.setValue(fileName, forHTTPHeaderField: "image")
let defaultConfigObject:URLSessionConfiguration = URLSessionConfiguration.default
let defaultSession:URLSession = URLSession(configuration: defaultConfigObject, delegate: FYIURLSessionDelegate(), delegateQueue: OperationQueue.main)
let task = defaultSession.dataTask(with: request as URLRequest, completionHandler: { data, response, error in
guard error == nil && data != nil else {
DispatchQueue.main.async {
completionHandler(nil, error as NSError?)
}
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
var message = ""
if let dta = data{
do {
let json = try? JSONSerialization.jsonObject(with:dta, options: JSONSerialization.ReadingOptions.allowFragments) as? NSDictionary
message = json??.object(forKey: "message") as? String ?? ""
}
}
let httpError:NSError = NSError(domain: "HTTP", code: httpStatus.statusCode, userInfo: FYIConnection.userInfo(message))
DispatchQueue.main.async {
completionHandler(nil, httpError)
}
return
}
if (data != nil) {
do {
let json:NSDictionary = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.allowFragments) as! NSDictionary
let api_status:Bool = json.object(forKey: "api_status") as! Bool
if (api_status){
DispatchQueue.main.async {
completionHandler(json,nil)
}
}else {
let message:String = json.object(forKey: "message") as! String
let httpError:NSError = NSError(domain: FYIConnection.bundleIdentifier(), code: FYIError.apiError.rawValue, userInfo: FYIConnection.userInfo(message))
DispatchQueue.main.async {
completionHandler(nil, httpError)
}
}
} catch let jsonError as NSError {
DispatchQueue.main.async {
completionHandler(nil,jsonError)
}
}
}else {
let httpError:NSError = NSError(domain: FYIConnection.bundleIdentifier(), code: 1, userInfo: FYIConnection.userInfo(""))
DispatchQueue.main.async {
completionHandler(nil, httpError)
}
}
})
task.resume()
return task
}
And the body is
override func createBodyWithParameters(_ parameters: [String: String]?, image: UIImage?, paths: [String]?, boundary: String) -> Data {
let body = NSMutableData()
let data = UIImagePNGRepresentation(image!)
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name=\"file\"; filename=\"" + (self.txtMobileNumber?.text ?? "") + ".png" + "\"\r\n")
body.appendString("\r\n")
body.append(data!)
body.appendString("\r\n")
body.appendString("--\(boundary)--\r\n")
return body as Data
}

Answer 1

Try to fix body like this:
override func createBodyWithParameters(_ parameters: [String: String]?, image: UIImage?, paths: [String]?, boundary: String) -> Data {
let body = NSMutableData()
let mimeType = "image/jpeg"
let data = UIImagePNGRepresentation(image!)
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name=\"file\"; filename=\"" + (self.txtMobileNumber?.text ?? "") + ".png" + "\"\r\n")
body.appendString("Content-Type: \(mimeType)\r\n\r\n")
body.appendString("\r\n")
body.append(data!)
body.appendString("\r\n")
body.appendString("--\(boundary)--\r\n")
return body as Data
}
Also try to add this:
request.setValue(String(describing: formData.length), forHTTPHeaderField: "Content-Length")
